Most residential replacements in Illinois today use architectural shingles. Read the full guide. Three-tab shingle A single-layer asphalt shingle cut into three equal tabs. It is flatter and usually carries a shorter warranty and lower wind rating than an architectural shingle. Read the full guide. Class 4 impact-resistant shingle A shingle that passed the UL 2218 impact test at its highest level (Class 4), in which a 2-inch steel ball is dropped onto the same spot twice without cracking the shingle. Some insurers offer premium discounts for them. Read the full guide. Wind uplift rating A shingle's tested resistance to being lifted by wind, stated as a wind speed or test class. The rating only applies when the shingle is installed to the manufacturer's nailing instructions. Read the full guide. Underlayment The water-resistant layer installed over the roof deck and under the shingles. Synthetic underlayment is lighter and more tear-resistant than traditional asphalt-saturated felt.

Practical advice from a GAF-certified Illinois contractor. **Content:** Cost & Financing Trill publishes ranges — not bait pricing. These guides explain how roof cost is calculated in Illinois, what drives the variance, and the financing options Trill offers for replacements. Cost Calculator (Illinois) Interactive estimator using current Illinois material and labor rates. Cost by Roof Size Square-foot pricing brackets for typical Illinois homes. Cost by Shingle Type Three-tab vs architectural vs luxury — installed-price differences. Roof Cost vs Home Value How much of a roof replacement returns at resale in Madison County. Emergency Roof Repair Cost After-hours and tarp pricing — what Trill charges and why. Financing Options (Illinois) 0% APR, HELOC, and personal loan paths Trill customers use most. HELOC vs Personal Loan Tax implications, rates, and lien differences explained. Illinois Insurance Claim Paths How State Farm, Allstate, and Farmers each handle Illinois roof claims. Compare Roofing Cost in the Context of the Whole System Roofing cost depends on the measured roof area, pitch, number of layers, access, tear-off requirements, decking condition, flashing, ventilation, material choice, and the details around valleys, walls, chimneys, and penetrations. A price based only on square footage cannot show the full scope of a specific property. The cost and financing guides in this section explain common pricing terms, the difference between roof area and floor area, factors that change an estimate, and questions to ask when comparing proposals. They are intended to help property owners understand what is included rather than predict an exact price without an inspection. Compare written scopes line by line. Look for material specifications, underlayment, flashing, ventilation, disposal, warranties, and how unexpected decking work will be handled. Trill Roofing can inspect the property and prepare an estimate based on the roof that is actually there. Cost & Financing: common questions Is Trill Roofing licensed and insured in Illinois?… --- ### Process & Scheduling - **URL:** https://trillroofing.com/resources/process-and-scheduling/ - **Published:** 2026-05-13 - **Modified:** 2026-08-20 - **Author:** Andy Pfleger **Summary:** Process And Scheduling, expert roofing guide from Trill Roofing. Practical advice from a GAF-certified Illinois contractor. **Content:** Process & Scheduling Trill installs roofs in 1–3 days from the day the trucks arrive. These guides walk through what to expect from your first call through the final walk-through. What to Expect on Install Day Crew arrival, dumpster placement, tear-off, and clean-up — hour by hour. How Long Does a Roof Replacement Take Realistic timelines by roof size, weather, and complexity. Pre-Installation Checklist What to move, cover, or unplug the day before Trill arrives. Roof Inspection Report Explained How to read the report Trill leaves after every inspection. Scheduling a Roof Replacement When to call, when materials arrive, and how weather affects the date. Trill Warranty Registration How Trill registers your manufacturer warranty on your behalf. Plan the Roofing Process Around the Property Roofing schedules depend on more than the installation date. Material availability, weather, roof complexity, access, permits, property use, and the scope discovered during inspection can all affect timing. A clear process helps the owner understand what must happen before crews arrive and what to expect while work is underway. These guides cover inspection, estimating, scheduling, preparation, installation, cleanup, and final review. They also explain practical details such as moving vehicles, protecting items near the house, planning around pets, and keeping access clear for materials and equipment. Ask questions early if the property has limited access, business hours, shared driveways, solar equipment, landscaping concerns, or interior areas that need special protection. Trill Roofing can account for those conditions while planning the work and communicate changes if weather or hidden roof conditions affect the schedule. Process & Scheduling: common questions Is Trill Roofing licensed and insured in Illinois? Yes.

Practical advice from a GAF-certified Illinois contractor. **Content:** Insurance & Storm Damage Storm season in Illinois means hail, wind, and ice. These guides explain what insurance covers, how to document damage, and how to navigate a claim without giving up your right to choose your contractor. Ice Dam Prevention Why ice dams form and the two roof details that prevent them. Hail Damage Roof Assessment How adjusters score hail strikes and what counts as a covered claim. Roof Insurance Claim Documentation The photo, video, and contractor-report stack that wins claims. Roof Warranty Types Manufacturer warranties versus workmanship warranties — what each actually covers. Choosing a Roofing Contractor in Illinois Licensing, insurance, and reference checks that separate Trill from storm-chasers. Document Storm Damage Before Making Roofing Decisions After a severe storm, start with safety and visible documentation. Photograph conditions from the ground, note the date and type of weather, and record interior leaks or new stains. Avoid climbing onto a wet, steep, or visibly damaged roof. Missing shingles, displaced metal, debris impact, and damaged gutters can justify a closer inspection. The insurance and storm-damage guides in this section explain the difference between documenting a condition and determining coverage. Policy language, deductibles, age, prior damage, and the cause of loss can affect a claim. A roofer can document roofing conditions and repair options, while the insurance carrier determines what the policy covers. If temporary protection is needed, keep receipts and photographs of the condition before and after the work. Clear records make conversations with the roofer and insurer easier. Trill Roofing can inspect the roof, identify visible storm-related concerns, and explain the roofing work that may be required. Insurance & Storm Damage: common questions Is Trill Roofing licensed and insured in Illinois? Yes. Trill Roofing holds Illinois roofing contractor license #104.020330 through IDFPR and carries general liability and workers compensation… --- ### Repair & Maintenance - **URL:** https://trillroofing.com/resources/repair-and-maintenance/ - **Published:** 2026-05-13 - **Modified:** 2026-08-20 - **Author:** Andy Pfleger **Summary:** Repair And Maintenance, expert roofing guide from Trill Roofing. Practical advice from a GAF-certified Illinois contractor. **Content:** Repair & Maintenance A roof that gets attention twice a year lasts 25–30% longer than one that doesn’t. These guides cover the inspection cadence, common repairs, and maintenance habits that protect your investment. Roof Maintenance Schedule Spring and fall checklist Trill recommends for every Illinois homeowner. What a Roof Inspection Includes The 22-point inspection Trill runs — and what each item is looking for. Chimney Flashing Repair Why chimneys cause more leaks than any other roof penetration. Soffit & Fascia Repair When soffit rot signals a bigger ventilation problem upstream. Algae & Moss Removal Safe ways to remove black streaks and moss without voiding your shingle warranty. Use Maintenance to Catch Small Roofing Problems Earlier Roof maintenance is less about a single checklist and more about noticing change. Loose or missing shingles, lifted flashing, cracked sealant, clogged drainage, damaged pipe boots, and staining near penetrations can all deserve attention. Conditions after wind, hail, heavy rain, or freeze-thaw cycles are especially useful to document. The guides in this section explain how inspections, leak tracing, minor repairs, drainage, and routine observation fit together. They can help you recognize when a visual check is reasonable and when walking on a roof or opening a roofing assembly should be left to a trained roofer. If a problem is active, protect the interior when it is safe to do so and record where water appears. The point where moisture shows inside is not always directly below the roof entry point. A professional inspection can connect the interior evidence with roof-surface conditions and establish a practical repair plan. Repair & Maintenance: common questions Is Trill Roofing licensed and insured in Illinois? Yes. Trill Roofing holds Illinois roofing contractor license #104.020330 through IDFPR and carries general liability and workers compensation insurance.

Practical advice from a GAF-certified Illinois contractor. **Content:** Installation Details The line items that separate a 30-year roof from a 12-year roof are mostly invisible after installation — flashings, ventilation, ice barriers. These guides cover the install-day details Trill won’t cut corners on. Attic Ventilation Sizing How to calculate the intake and exhaust your attic needs to avoid premature shingle failure. Roof Flashing Explained Where flashing matters most and how Trill installs it on every penetration. Tear-Off vs Overlay Why Trill almost never recommends overlaying — and the two cases where it’s defensible. Ridge Vent vs Box Vent Continuous ridge ventilation versus traditional box vents on Illinois roofs. Madison County Roofing Permits Permits, inspections, and HOA paperwork Trill handles before tear-off day. Cold-Weather Roofing in Illinois What’s safe to install below 40°F and what we postpone until spring. Gutter & Roof Integration How drip edge, fascia, and gutters tie into a watertight system. Skylight Installation & Replacement Replacing skylights during a re-roof saves cost and prevents the most common leak source we see. TPO & EPDM Commercial Roofing Single-ply membrane options for flat and low-slope commercial buildings. Installation Details That Affect Long-Term Roof Performance A roofing system is more than the visible shingle or membrane. Decking, underlayment, ice and water protection, starter material, flashing, fasteners, ventilation, ridge details, drainage, and penetrations all work together. Weakness in one detail can allow water or heat problems even when the main roof covering looks intact. The guides in this section explain common installation terms and the purpose of key components. Use them to understand an estimate, prepare questions for a roofer, and recognize why two proposals with the same surface material may describe different scopes of work. Details should be selected for the roof design, manufacturer requirements, local conditions, and the property’s ventilation and drainage needs. Trill Roofing reviews those conditions… --- ### Materials & Shingles - **URL:** https://trillroofing.com/resources/materials-and-shingles/ - **Published:** 2026-05-13 - **Modified:** 2026-08-20 - **Author:** Andy Pfleger **Summary:** Materials And Shingles, expert roofing guide from Trill Roofing. Practical advice from a GAF-certified Illinois contractor. **Content:** Materials & Shingles From asphalt shingles to standing-seam metal, the material on your roof drives its lifespan, weather rating, and curb appeal. These guides break down the choices Illinois homeowners face — and the trade-offs Trill Roofing weighs on every estimate. Asphalt Shingle Types Compared Three-tab, architectural, and luxury shingles — what changes between tiers, and which Trill recommends for the Riverbend climate. Class 4 Impact-Resistant Shingles How Class 4 shingles cut hail-claim costs and unlock insurance discounts in Illinois. Roof Decking: OSB vs Plywood The decking decision most contractors don’t explain — and why it matters more than the shingle on top. Synthetic vs Felt Underlayment Why Trill stopped installing 15-lb felt and what synthetic underlayment buys you on day one and year fifteen. Wind Uplift Ratings in Illinois How shingle wind ratings line up with the gusts Illinois actually sees — and what to ask your installer. Drip Edge Installation The flashing detail Illinois code requires and most leaks trace back to. Roof Pitch & Material Choice Why a 4/12 pitch limits your material options and how to choose around it. Solar vs Passive Attic Ventilation Powered vents, ridge vents, and gable vents — which actually moves air in Madison County. Tile, Metal & Asphalt Compared A real cost-and-lifespan comparison for the three materials Trill installs most often. Standing-Seam Metal Roofing in Illinois When metal pays off in the Riverbend and when it’s overkill. Roof Lifespan by Material Realistic lifespan ranges by material — based on what Trill sees coming off Illinois homes. Materials & Shingles: common questions Is Trill Roofing licensed and insured in Illinois? Yes.

Here’s the honest breakdown of asphalt shingle categories – what’s different between them, what wind and impact ratings actually mean, and what we install on Illinois homes and why. The three categories that matter Asphalt shingles sold for residential roofs in the US fall into three real categories. Marketing materials add more names (“luxury,” “designer,” “premium architectural”) but for installation, warranty, and performance purposes there are three: 3-tab shingles – single-layer, thin, lightweight, lowest cost Architectural (dimensional, laminate) shingles – multi-layer, heavier, deeper shadow lines, most homes get these today Impact-resistant shingles – usually architectural in shape but built with a polymer-modified asphalt core that passes UL 2218 hail testing. Class 4 is the highest rating. “Designer” and “luxury” lines are architectural shingles with thicker laminations or aggressive shadow lines for a more dramatic look – they’re a subset of architectural, not a separate category. 3-tab shingles – when (not) to use them 3-tab shingles were the residential standard from the 1960s through the early 2000s. They’re recognizable by the three flat tabs cut into each shingle, creating a uniform striped appearance on the roof. Technical specs: Single layer of asphalt-coated fiberglass mat Wind warranty typically 60 mph (some lines warranty to 70 mph) Manufacturer warranty: 20-25 years (often pro-rated heavily after year 10) Weight: ~200-240 lbs per square (100 sq ft) Why we rarely install them in Illinois: our wind events regularly exceed 60 mph, and the wind warranty voids when shingles get blown off. The IBC-derived design wind speed… --- ### Trill Roofing Warranty Registration \| Trill Roofing - **URL:** https://trillroofing.com/resources/process-and-scheduling/trill-roofing-warranty-registration-process/ - **Published:** 2026-05-12 - **Modified:** 2026-10-05 - **Author:** Andy Pfleger **Summary:** Trill Roofing Warranty Registration Process By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor After your Trill Roofing installation is complete, we handle the... **Content:** Trill Roofing Warranty Registration Process By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor After your Trill Roofing installation is complete, we handle the manufacturer warranty registration with GAF, CertainTeed, or Owens Corning – depending on which line was installed. This is a step that gets skipped by less-organized contractors, and skipping it can void or weaken your warranty when you need it most. Here’s what we do, when we do it, and what you receive. Why warranty registration matters Most premium shingle warranties require registration within a specific window – typically 60 days from installation – to activate the full warranty terms. Without registration: The standard (limited) warranty applies, not the extended tier Some manufacturers reduce the labor warranty period Transferability to a new owner may be limited or voided Enhanced manufacturer warranties (such as GAF System Plus) cannot be registered later – the window is hard The registration is a 5-minute task. The consequences of skipping it can be tens of thousands of dollars in warranty value lost. When we register your warranty Within 30-60 days of your installation completing: We verify the install passed final inspection We document the products installed (line, color, batch numbers) We submit registration through the manufacturer’s contractor portal (GAF, CertainTeed, or OC) You receive a confirmation email with your warranty certificate The manufacturer mails you a printed warranty document within 4-6 weeks You don’t need to do anything during this process – we handle it on your behalf. GAF warranty we register As a GAF Certified Contractor, Trill Roofing registers the GAF System Plus Limited Warranty on qualifying installs: Available when the roof uses GAF shingles plus qualifying GAF accessory products (such as starter strip, ridge cap, and underlayment or leak barrier) Enhanced coverage on GAF… --- ### Illinois Roof Insurance Claims by Carrier \| Trill Roofing - **URL:** https://trillroofing.com/resources/cost-and-financing/illinois-roof-insurance-claims-state-farm-allstate-farmers/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** IL Roof Insurance Claims: State Farm, Allstate, Farmers, American Family By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Four insurance carriers dominate the... **Content:** IL Roof Insurance Claims: State Farm, Allstate, Farmers, American Family By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Four insurance carriers dominate the Illinois homeowner market: State Farm, Allstate, Farmers, and American Family. Each handles roof storm damage claims slightly differently – different adjuster processes, different scope preferences, different supplement-approval patterns. This guide covers the carrier-specific details so you know what to expect when filing. State Farm – Illinois’s largest carrier State Farm holds approximately 25-30% of IL homeowner market share, particularly strong in the Riverbend and central Illinois. Claim process: File via State Farm mobile app, online portal, or local agent Adjuster assigned within 24-72 hours Site inspection typically scheduled within 7-14 days Decision and scope within 14-30 days of inspection What to know: State Farm uses both staff adjusters and independent adjusters; service quality varies Scopes are typically reasonable but sometimes miss code-required items (ice barrier extent, drip edge) Supplements are approved when properly documented – we use code citations and itemized line items Class 4 impact-resistant shingle discount: typically 5-15% on renewal premiums Deductibles: usually $1,000-$2,500 standard; some policies have separate higher wind/hail deductibles ($2,500-$5,000) State Farm is generally cooperative with contractor adjuster-meets when scheduled in advance. Allstate Allstate holds approximately 10-15% of IL market share. Claim process: File via Allstate app, allstate.com, or 1-800-ALLSTATE Adjuster assigned within 24-48 hours Inspection within 7-14 days Scope and decision within 30 days typically What to know: Allstate often uses third-party adjuster firms for storm claims Scopes can be aggressive in the carrier’s favor – submitting supplements is more common Their “Impact-Resistant Roofing” discount is one of the larger ones in IL (often 5-25%) Deductibles: $1,000-$2,500 standard; wind/hail deductibles sometimes percentage-based (1-2% of dwelling coverage) Working with Allstate often involves more documentation back-and-forth.… --- ### HELOC vs Personal Loan for a Roof \| Trill Roofing - **URL:** https://trillroofing.com/resources/cost-and-financing/heloc-vs-personal-loan-for-roof/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** HELOC vs Personal Loan: Which Is Better for a New Roof?

By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor For homeowners financing a roof replacement outside contractor-offered 0% APR programs, the two main options are a HELOC (home equity line of credit) or a personal loan. They look similar – both can fund a roof project – but the underlying mechanics, rates, and risks are quite different. This guide compares them head-to-head for Illinois homeowners. Side-by-side comparison Feature HELOC Personal loan Collateral Your home None (unsecured) Current IL rates (2026) Prime + 0-2% (~8-12%) 8-18% based on credit Rate type Variable Usually fixed Repayment term 10-20 years 2-7 years Approval time 30-60 days 1-5 days Closing costs $0-$1,000+ Origination fee or none Tax deductibility Yes if used for home improvement Generally no Default consequence Foreclosure risk Credit damage; no asset loss Flexibility Draw as needed during draw period Single lump sum When HELOC is the better choice HELOC makes more sense when: You have substantial home equity (typically 20%+ available to borrow against) You want flexibility to draw for the roof now and other projects later (bathroom, kitchen, etc.) You can handle variable rates – if rates rise, your payment rises You want the lowest current rate – HELOCs are typically 2-6% cheaper than personal loans You want a longer repayment timeline with lower monthly payments Tax deductibility matters – interest may be deductible if used for capital home improvements (consult tax advisor) HELOC drawbacks: Slow to set up (30-60 days) Variable rate exposure Your home is collateral Some lenders require appraisals (~$400-$600) When personal loan is the better choice Personal loan makes more sense when: You don’t want your home as collateral – keeping the roof investment separate from home equity simplifies… --- ### Roof Financing Options Illinois \| Trill Roofing - **URL:** https://trillroofing.com/resources/cost-and-financing/roof-financing-options-illinois/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Roof Financing Options for Illinois Homeowners By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor A $15,000-$25,000 roof replacement isn’t usually a cash purchase.... **Content:** Roof Financing Options for Illinois Homeowners By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor A $15,000-$25,000 roof replacement isn’t usually a cash purchase. Most Illinois homeowners finance the project across one of several common paths. This guide compares them – contractor-offered financing, home equity products, unsecured loans, credit cards – with realistic rates and pros/cons for each. Option 1: Contractor-offered financing Most established roofing contractors (Trill Roofing included) partner with consumer finance companies that offer point-of-sale financing for the project. Common terms: 0% APR promotional periods – typically 12-24 months, sometimes 60+ months for higher-tier programs Standard APR after promo – 15-30% (high if you don’t pay off during the promo) Loan amounts – typically $5,000-$100,000 Approval speed – same-day approval at signing Credit requirements – most programs require 650+ FICO; some have lower thresholds Best for: homeowners who can pay off within the promotional 0% period. The convenience of point-of-sale + 0% interest if paid on time is hard to beat. Worst case: if you don’t pay off during the promo, the deferred interest can hit retroactively (depending on program). Read the terms. Option 2: Home Equity Line of Credit (HELOC) If you have home equity, a HELOC lets you borrow against it at variable rates. Current IL HELOC rates (2026): typically prime + 0-2%, so 8-12% APR Limits: up to 80-90% of home equity Setup time: 30-60 days for new HELOCs; immediate use if you already have one Repayment: interest-only during draw period (typically 10 years), then principal + interest for 10-20 years Tax deductibility: interest may be tax-deductible if used for home improvement (consult your tax advisor) Best for: homeowners with existing HELOCs who can draw against them immediately, or those planning multiple home improvements and wanting flexible access to… --- ### Emergency Roof Repair Cost \| Trill Roofing - **URL:** https://trillroofing.com/resources/cost-and-financing/emergency-roof-repair-cost/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Emergency Roof Repair Cost in Illinois By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor When you have water coming through your ceiling, the... **Content:** Emergency Roof Repair Cost in Illinois By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor When you have water coming through your ceiling, the question of cost is real but secondary. The first priority is stopping further damage. This guide explains what emergency roof response actually costs in the Riverbend, what insurance covers, and when an emergency repair is the right call vs full replacement. What “emergency” means Emergency roof response is for situations where: Water is actively entering the house (visible leak, wet drywall, dripping) Wind or storm damage has created an opening in the roof system A tree fell on the roof Interior damage will compound rapidly without intervention Distinguished from urgent (need within days but not immediately) or routine (need within weeks). Emergency tarping cost Emergency tarping is the most common first-response work – install a heavy-duty plastic tarp over the damaged area, secure with battens, weight, or screws to prevent further water entry. Cost ranges: Standard tarp (single area, accessible) – $300-$600 Multiple-area tarp (storm damage across multiple slopes) – $600-$1,500 Complex tarp (steep pitch, multi-story, late-night response) – $800-$2,000 After-hours surcharge (nights, weekends) – typically 50-100% over standard daytime rates Tarping is a temporary fix – typically lasts 30-60 days before needing replacement or permanent repair. The cost is usually covered by homeowner insurance as a “mitigation” expense when filed under a storm claim. Active leak repair (without tarp) For situations where the damage is localized and can be repaired immediately: Single failed pipe boot – $250-$450 Flashing repair at one penetration – $400-$800 Replacement of a few missing shingles – $200-$500 Valley repair – $800-$2,000 Soft spot patch (small decking section) – $400-$900 Same-day response charges typically add $100-$300 over scheduled-repair pricing. Weekend/after-hours charges are higher.

By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Homeowners considering a roof replacement often ask whether the cost translates to higher home value. The answer is nuanced: a new roof doesn’t add value dollar-for-dollar, but it can prevent value loss, accelerate a sale, and pass home inspections without negotiation. This guide explains the real impact on appraisal, resale, and inspection outcomes for Illinois homes. Appraisal impact – what new roof actually adds When an appraiser values your home, the roof is one factor among many. A new roof affects appraisal in two ways: Direct value add – typically 50-70% of replacement cost. A $15,000 roof replacement might add $7,500-$10,500 to the home’s appraised value. Avoided value reduction – a roof clearly at end of life (15+ years old, granule loss, leaks) reduces the home’s appraised value or appraises only to “as-is condition.” New roof eliminates this penalty. The direct-value calculation is real but doesn’t recover the full cost. The avoided-loss calculation is often the bigger driver – a $15,000 roof that prevents a $20,000-$30,000 valuation penalty has effectively returned more than 100%. Resale impact in Illinois A roof in good condition affects resale several ways: Faster sale. Homes with new or recent roofs sell 5-15% faster in IL markets. Days on market matters because each week reduces sale price slightly. Higher sale price. Same-style homes in the same neighborhood with a recent roof sell for 2-5% more. Fewer inspection issues. Home inspectors flag old roofs in their reports; buyers use this for price negotiation. New roofs pass inspection cleanly. Insurance binding. Some buyers can’t get homeowner insurance bound (or pay much higher premiums) for homes with old or damaged roofs.

Choice becomes about upfront budget, aesthetic, and ownership timeline. 3-tab (skip these unless matching) 3-tab shingles are 60% of mid-1990s Illinois roofs but rarely the right choice for a new install today. Pros: cheapest upfront Cons: low wind rating (60 mph), short lifespan, shorter warranty, looks dated. We don’t recommend 3-tab unless matching an existing partial roof.

This guide shows realistic 2026 Riverbend pricing for common Illinois home sizes – from a small 1,500 sq ft ranch through a 4,000 sq ft two-story – so you can match your home to a price range before getting quotes. How to estimate your roof’s square footage The fast estimate: take your home’s floor area and multiply by a pitch factor: Low pitch (3/12-4/12): floor area × 1.25 Standard pitch (5/12-6/12): floor area × 1.4 Steep pitch (7/12-9/12): floor area × 1.55 Very steep (10/12+): floor area × 1.75 Example: a 2,000 sq ft single-story home with a 6/12 pitch = approximately 2,800 sq ft of roof surface. This estimate is rough. A real measurement (which we do during the inspection) accounts for overhangs, dormers, hips, and other complexity. Pricing by roof size – standard architectural Mid-range architectural shingles (GAF Timberline HDZ or equivalent), standard installation in the Riverbend: Roof size (sq ft) Low end High end Typical 1,500 $6,750 $10,500 $8,250 2,000 $9,000 $14,000 $11,000 2,500 $11,250 $17,500 $13,750 3,000 $13,500 $21,000 $16,500 3,500 $15,750 $24,500 $19,250 4,000 $18,000 $28,000 $22,000 “Typical” is the median; your specific quote moves based on complexity, decking condition, and shingle tier (covered in the cost calculator).

From there, six variables move your specific quote up or down. This guide explains each variable, gives realistic ranges, and lets you build a rough estimate for your home before any contractor walks the roof. Variable 1: Roof square footage Total roof surface area, not floor area. Roof square footage is typically 1.3-1.7x the home’s floor area depending on pitch and overhangs. For a typical 2,000 sq ft floor-area home: Low-pitch (4/12): ~2,400-2,800 sq ft of roof Standard pitch (6/12): ~2,800-3,200 sq ft of roof Steep pitch (9/12+): ~3,200-3,800 sq ft of roof Cost at $5.50 per sq ft midpoint: 2,500 sq ft roof: ~$13,750 3,000 sq ft roof: ~$16,500 3,500 sq ft roof: ~$19,250 Variable 2: Pitch Steeper roofs cost more to install (labor + safety): 2/12-5/12 (low to moderate): base pricing 6/12-8/12 (standard): base pricing, no premium 9/12-10/12 (steep): ~15-25% labor premium 11/12-12/12+ (very steep): ~30-50% labor premium Pitch premium reflects the slower work, roof jacks, and safety harnessing required. Variable 3: Complexity (valleys, dormers, chimneys) A simple gable roof is cheapest. Each complexity element adds labor: Each valley: +$300-$500 for labor and flashing Each dormer: +$400-$800 for cut shingles and flashing Each chimney: +$600-$1,400 for re-flashing (more if cricket needed for wide chimneys) Each skylight: +$200-$400 for flashing integration Other penetrations (pipes, vents): minor add per item A roof with 4 valleys + 2 dormers + 1 chimney + 1 skylight = $2,500-$4,500 in complexity premium over a simple gable of the same square footage.

Knowing how scheduling works lets you plan around the right window for your project – whether that’s locking in spring availability now, getting urgent storm damage handled fast, or scheduling around weather sensitivities. This guide explains realistic timing by season. The Illinois roofing season Practical Illinois roofing happens roughly April through November, with peak activity May through October. Outside this window: December-February – emergency work only (active leaks, claim deadline projects). Cold-weather installation has performance implications (see our cold-weather roofing guide). March – variable. Some years allow March installs; others stay too cold and wet. April-November – normal scheduling. Lead times vary by season within this window. Lead times by season For non-urgent replacements (you have a working roof, planning ahead): Season Typical lead time Why Early spring (Apr-May) 4-6 weeks High demand from winter-damaged roofs + homeowner planning Mid spring (May) 3-5 weeks Peak season pressure Early summer (Jun) 2-4 weeks Demand stabilizes Mid summer (Jul-Aug) 2-3 weeks Standard scheduling; storm work can shift things Late summer (Aug-Sep) 1-3 weeks Demand drops slightly Fall (Oct-Nov) 1-2 weeks End-of-season urgency from homeowners wanting to beat winter Emergency leaks and storm damage with active interior issues are prioritized and typically scheduled within days regardless of season. What “lead time” actually means Lead time is the duration from when you sign the contract to the day install starts. It includes: 1-2 days for material ordering 1-3 days for shingle delivery to the supplier 1-2 weeks for shingle delivery from supplier to jobsite (varies by manufacturer + season) Permit application + approval (typically 2-5 business days in… --- ### Roof Inspection Report Explained \| Trill Roofing - **URL:** https://trillroofing.com/resources/process-and-scheduling/roof-inspection-report-explained/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** What’s in a Trill Roofing Inspection Report By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Every Trill Roofing free inspection produces a written... **Content:** What’s in a Trill Roofing Inspection Report By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Every Trill Roofing free inspection produces a written PDF report that you keep regardless of whether you hire us for the work. This guide walks through what’s in the report, why each section matters, and how you can use the document – for insurance claims, second-opinion comparisons, or just personal records. Section 1 – Property summary The first page of the report includes: Property address and inspection date Inspector name and IL roofing license number Roof system summary: estimated age, shingle type, approximate square footage Roof pitch and geometry notes Existing ventilation summary (intake/exhaust types) Building geometry: number of stories, attached structures, complexity score This section establishes the baseline of what we’re looking at. Useful for insurance claim documentation and for comparing quotes across contractors.

This is the checklist we walk through with every Trill Roofing customer – what to do inside the house, outside, and with your schedule so install day goes smoothly. Inside the house – attic prep Tear-off creates vibration and dust that drops from the rafters into the attic. Anything stored there that’s sensitive should be covered or moved: Holiday decorations in cardboard boxes (cover with plastic sheets) Stored clothing or fabric items (dust gets into fibers) Electronics or appliances (cover with sheets) Items immediately below the attic hatch (most likely to receive falling dust) You don’t need to clear the attic – just cover dust-sensitive items. Inside the house – ceiling-mounted items Vibration from hammers and dropped shingles can rattle ceiling fixtures: Ceiling fans – let them stop (don’t run during install) Hanging light fixtures with delicate glass shades – consider removing the shade temporarily Wall-mounted artwork on ceiling-adjacent walls – secure or temporarily remove Picture frames close to the ceiling – check fasteners Major damage from vibration is rare but light shades occasionally fall. A few minutes of pre-install securing prevents the problem. Outside the house – driveway and yard The driveway becomes the staging area for the dumpster, crew vehicles, and materials: Move cars to the street the night before Move bikes, lawn equipment, and other driveway items Clear the entryway so crew has access to the front door If you have a basketball hoop on the driveway, plan to relocate or accept it will be near the dumpster Yard: Trim back shrubs immediately adjacent to the house… --- ### How Long Does a Roof Replacement Take? \| Trill Roofing - **URL:** https://trillroofing.com/resources/process-and-scheduling/how-long-does-a-roof-replacement-take/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** How Long Does a Roof Replacement Take?

By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor For most Illinois homes, a roof replacement is a one-day job. But “one day” hides a range – a 1,500 sq ft single-gable ranch wraps in 6 hours; a 3,500 sq ft Victorian with three chimneys and four valleys can take 2-3 days. This guide explains what actually drives the timeline so you can plan around your install accurately. The variables that drive install time Five factors set the duration of a roof replacement: Roof square footage. A 1,500 sq ft roof is dramatically faster than 3,500 sq ft. Each additional 1,000 sq ft adds ~3-4 hours of crew time. Pitch. Steep roofs (8/12+) require roof jacks, slower foot placement, and safety harnessing. A 12/12 roof takes 30-50% longer than the same size at 5/12. Complexity. Valleys, dormers, hips, chimneys, skylights, and other penetrations all add time. A simple gable roof is fastest; a roof with 4 valleys and 2 chimneys can take twice as long for the same square footage. Decking condition. If significant decking needs replacement (10+ sheets), each sheet adds 10-20 minutes plus material time. Weather window. If a storm forces a mid-day stop, the schedule extends a day. Crews often wrap the roof at a safe stopping point and resume the next morning. Typical durations by roof size Roof size Simple gable Moderate complexity Complex (valleys, dormers) Under 1,500 sq ft 4-6 hours 6-8 hours 1 day 1,500-2,500 sq ft 6-9 hours (1 day) 1 day 1-1.5 days 2,500-3,500 sq ft 1 day 1-1.5 days 2 days Over 3,500 sq ft 1.5 days 2 days 2-3 days These assume a 4-6 person crew working a 9-hour day.

The goal is no surprises: you know when to move cars, what noise to expect, how the property will be left, and when the work is done. Before install day (the week before) About a week before your scheduled install date: Materials delivery – Shingles, underlayment, ice barrier, drip edge, and flashing arrive at your property typically 1-3 days before install. We coordinate placement (driveway is most common; sometimes side yard for steeper homes). Permit posted – Madison County or your village’s building permit is posted at the front of the property. Weather confirmation – We monitor the forecast and confirm 24-48 hours out. If a major rain event is forecast for install day, we’ll reschedule rather than start. Final walkthrough call – Your project manager confirms the scope, parking, and any access concerns. Morning of install – 6:30-7:30 AM The crew arrives early to start when it’s cool and to maximize daylight: Crew foreman walks the perimeter with you (or alone if you’re at work) for a final scope check Tarps and plywood placed against the house, over landscaping, and over windows to protect from falling debris Ladders and roof jacks set up for safety Magnetic sweep equipment positioned for end-of-day cleanup This is the loudest stage – equipment unloading, ladders extending. About 30-45 minutes of setup before actual roof work begins. Tear-off – 8:00 AM to 11:00 AM The crew strips the existing shingles, underlayment, and any failing flashing down to the decking.

This guide gives realistic lifespan ranges for common roofing materials in Illinois climate, plus what shortens those lifespans and what extends them. Asphalt shingle lifespan ranges Asphalt shingle lifespan in IL climate, based on field observation rather than marketing claims: 3-tab shingles: 15-20 years typical; 25 years on premium 3-tab in ideal conditions Standard architectural shingles (30-year line): 22-28 years typical Premium architectural (50-year line): 28-35 years typical; 40+ years on the highest-end with excellent installation and conditions Class 4 impact-resistant: same lifespan as the underlying architectural design (typically 25-35 years), but with much higher hail resilience Designer/luxury asphalt: 35-50 years with quality installation The “lifetime warranty” you see on most premium architectural is technically lifetime of the original purchaser, but the warranty pro-rates aggressively after year 15. Practical replacement timing is when the shingles show widespread granule loss, curling, or repeated leak issues – typically 25-35 years on quality architectural. What shortens asphalt shingle life Several factors reduce shingle lifespan below the typical range: Inadequate attic ventilation – by far the biggest lifespan reducer. Hot attic temps cook the asphalt from below, accelerating aging. Excessive walking – HVAC techs, cable installers, antenna installations create granule loss and stress on shingles Heavy tree shade with no algae-resistant granules – algae colonies hold moisture and accelerate granule loss Improper installation – wrong nail placement, missing starter strips, poor flashing Hail and severe weather events – major storms can effectively cut years off a shingle’s… --- ### TPO and EPDM Commercial Roofing \| Trill Roofing - **URL:** https://trillroofing.com/resources/installation-details/tpo-epdm-commercial-roofing/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** TPO and EPDM Commercial Roofing By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Commercial buildings – and many residential additions, garage roofs, and... **Content:** TPO and EPDM Commercial Roofing By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Commercial buildings – and many residential additions, garage roofs, and low-slope porch roofs – use single-ply membrane systems instead of asphalt shingles. The two dominant products are TPO (thermoplastic polyolefin) and EPDM (ethylene propylene diene monomer, a synthetic rubber). This guide compares them, explains when each makes sense, and covers what’s involved in installation and warranty. Why single-ply membrane on low-slope roofs Asphalt shingles require minimum 2/12 pitch to shed water effectively. Below that, water can pool and find its way under the shingles. For roofs in the 1/4:12 to 2:12 range (most commercial buildings, many residential additions and porches), shingles aren’t an option. Single-ply membrane systems use a continuous sheet of synthetic material covering the entire roof. The seams are heat-welded (TPO) or seam-taped (EPDM) into watertight joints. Because there are no shingles to lift in wind or accumulate water in low spots, single-ply works on essentially flat roofs. The two products dominate this market: TPO and EPDM. TPO (thermoplastic polyolefin) TPO is a white reflective single-ply membrane introduced commercially in the early 1990s. It’s now the dominant choice for new commercial flat roofs in the US. Specs: Color: typically white (reflective); gray and tan also available Thickness: 45, 60, or 80 mil – thicker grades have longer life and warranty Lifespan: 20-30 years Cost: $5-$10 per sq ft installed Installation: heat-welded seams (hot air gun creates a continuous bond) Reflectance: high (white surface reduces summer cooling load – meaningful for commercial cooling costs) Pros: Reflective surface reduces cooling costs White appearance can qualify for ENERGY STAR roofing Heat-welded seams are very strong and watertight Good chemical resistance Cons: White surface shows dirt easily Some debate about long-term UV… --- ### Standing Seam Metal Roofing in Illinois \| Trill Roofing - **URL:** https://trillroofing.com/resources/materials-and-shingles/standing-seam-metal-roofing-illinois/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Standing Seam Metal Roofing for Illinois Homes By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Standing seam metal roofing is the most common... **Content:** Standing Seam Metal Roofing for Illinois Homes By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Standing seam metal roofing is the most common premium roofing alternative to asphalt shingles on Illinois homes. The visible vertical seams, longer lifespan, and lower-maintenance profile appeal to homeowners building or renovating in a contemporary, farmhouse, or barn-style aesthetic. This guide covers what standing seam actually is, the panel material choices, profile options, costs, and when it makes more sense than premium asphalt. What “standing seam” means Standing seam refers to the seams between roof panels. The panels (typically 12-24 inches wide) run vertically from eave to ridge. The edges of adjacent panels are bent upward and locked together, creating a raised “standing” seam between every panel. The seam is the structural connection. It’s also the visual character of the roof – those vertical lines from eave to ridge define the standing-seam look. Critically: the fasteners (screws or clips) are concealed inside the seams. You don’t see exposed fasteners on the panel face. This is the difference between standing seam and “exposed-fastener” or “R-panel” metal roofing – exposed fastener roofs use visible screws through the panel face, which is fine for barns and outbuildings but rarely appropriate for residential. Panel materials Standing seam panels are made from several materials, each with different characteristics: Galvalume steel – most common for residential standing seam in IL. Steel core coated with an aluminum-zinc alloy. Painted with Kynar finish for color and UV resistance. Lifespan: 40-60 years Cost: mid-range ($9-$13 per sq ft installed) Maintenance: low Best for: most residential applications Aluminum – softer metal, doesn’t rust at all (even in coastal environments). Lighter than steel. Lifespan: 40-50 years Cost: slightly higher than galvalume ($10-$15) Maintenance: low Drawback: dents more easily than… --- ### Tile vs Metal vs Asphalt Roofing Compared \| Trill Roofing - **URL:** https://trillroofing.com/resources/materials-and-shingles/tile-metal-asphalt-roofing-compared/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Tile vs Metal vs Asphalt: Roofing Material Comparison By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Asphalt shingles cover about 80% of Illinois... **Content:** Tile vs Metal vs Asphalt: Roofing Material Comparison By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Asphalt shingles cover about 80% of Illinois roofs because they hit the right balance of cost, performance, and ease of installation. But they’re not the only option. Standing seam metal is increasingly common on premium homes. Clay and concrete tile, while rare in our region, appear on certain architectural styles. This guide compares all three across the dimensions that matter for an Illinois homeowner. Asphalt shingles – the baseline Asphalt shingles dominate the IL residential market for clear reasons: Cost: $4.50-$8.50 per square foot installed for architectural; less for 3-tab; more for Class 4 impact-resistant Lifespan: 20-30 years for architectural; 15-25 for 3-tab Weight: 200-340 lbs per square – standard roof framing handles easily Installation labor: standardized, available from any local roofer Warranty: 30-50 year manufacturer warranties standard Repair-ability: easy to repair, individual shingles can be replaced Aesthetic flexibility: wide range of colors, textures, and styles (including slate-look and shake-look) For most Illinois homes, asphalt is the right answer. The other materials make sense in specific situations. Standing seam metal roofing Metal roofing on residential homes typically means standing seam – panels with raised vertical seams running from eave to ridge. The seams are mechanically locked or snap-lock and the panels are concealed-fastener (no exposed nails or screws on the visible roof).

The reality is more nuanced. For most Illinois homes, a well-balanced passive ventilation system (ridge vent + soffit intake) outperforms a solar attic fan added to an unbalanced system. This guide compares the two approaches and explains when solar fans make sense. How attic ventilation should work The goal of attic ventilation is to maintain airflow that: Removes hot air in summer (reduces cooling load, extends shingle life) Removes moisture year-round (prevents condensation on the deck underside) Keeps the roof deck temperature uniform (prevents ice dams in winter) Passive ventilation accomplishes this using the stack effect: warm air rises, exits at the ridge, and pulls cool air in at the soffits. No moving parts, no electricity, runs continuously. Solar fans add active exhaust – a fan pulls air out of the attic more aggressively than passive flow alone. The question is whether that aggressive pull helps or hurts. For the detailed sizing math, see our attic ventilation sizing guide. This piece focuses on the active-vs-passive question. When solar fans actually help Solar attic fans deliver real benefit in specific situations: Attics where passive ridge vent isn’t installable – complex hip roofs with short ridge lengths, or homes where the roof geometry doesn’t accommodate continuous ridge vent Specific zones of large attics – multi-section attics where one part doesn’t connect to the ridge vent stack effect Retrofit ventilation – homes where re-roofing isn’t planned but ventilation needs improvement; solar fan can be added without major work Above garage or workshop attics – heat extraction in spaces that get very… --- ### Skylight Installation and Replacement \| Trill Roofing - **URL:** https://trillroofing.com/resources/installation-details/skylight-installation-and-replacement/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Skylight Installation and Replacement Guide By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Skylights add daylight, ventilation, and architectural character to a home... **Content:** Skylight Installation and Replacement Guide By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Skylights add daylight, ventilation, and architectural character to a home – but they’re also the single most leak-prone roof penetration. When a skylight is installed correctly and the right product is selected, it can last 25-30 years. When it’s installed wrong, it starts leaking within years. This guide covers skylight types, when to replace vs reflash, what to specify, and how skylights integrate with a full roof replacement. Skylight types – curb-mounted vs deck-mounted Two main installation styles for residential skylights: Curb-mounted skylights – a wood frame (“curb”) is built up from the roof deck, typically 4-6 inches tall. The skylight unit sits on top of the curb. The roofing material wraps up the sides of the curb and is flashed at the top edge. Pros: more weatherproof (skylight is elevated above the roof surface), easier to replace without disturbing roof shingles Cons: more visible profile, can look bulky from outside Best for: low-slope roofs, modern aesthetic, replacement projects Deck-mounted skylights – the skylight unit mounts directly to the deck, flush with the roof surface. Roofing material flashes around the skylight frame. Pros: lower profile, more aesthetic on traditional roofs Cons: more vulnerable to wind-driven rain and snow accumulation, harder to replace without disturbing roofing Best for: steeper-pitched roofs, traditional aesthetics Both types work when installed correctly. The choice is largely aesthetic and depends on roof pitch and existing architecture. Why skylights leak – and how to prevent it Common skylight leak causes: Failed flashing. The metal flashing kit around the skylight has multiple components (sill, step, head, apron). If any piece is missing, undersized, or not lapped correctly with the surrounding shingles, water enters. Failed sealant on the glazing.… --- ### Gutter & Roof Integration \| Trill Roofing - **URL:** https://trillroofing.com/resources/installation-details/gutter-and-roof-integration/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Gutter & Roof Integration: When to Replace Together By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Gutters and roofs are different products installed... **Content:** Gutter & Roof Integration: When to Replace Together By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Gutters and roofs are different products installed at different times by different contractors. But they work together as a single water-management system – and when one fails, it often takes the other with it. This guide explains how the roof and gutter system interact, when to replace them together vs separately, and the drip edge details that determine whether the system actually works. How the roof-and-gutter system works together Picture a heavy rainstorm. Water hits the roof, runs down the slope to the eave, and needs to be captured by the gutter rather than running behind it onto the fascia, soffit, and wall. This handoff between roof and gutter is where most failure happens. The components that make it work: Drip edge at the eave – bends water out and over the gutter lip instead of letting it wick back behind Properly sized and positioned gutter – wide enough to capture flow, hung at the right angle and depth relative to the roof edge Adequate downspouts – enough capacity to carry the gutter’s water away Clean gutter – debris-free so water actually flows to the downspouts When all of these work, water from the roof leaves the property quickly. When any one fails, water finds the fascia, soffit, foundation, or basement. The drip edge + gutter relationship Drip edge is the L-shaped metal trim at the eave (covered in detail in our drip edge installation guide). For drip edge to work with a gutter: The drip edge has to extend over the back edge of the gutter, not just to the fascia The vertical leg of the drip edge has to drop into the gutter trough, not… --- ### Cold Weather Roofing in Illinois \| Trill Roofing - **URL:** https://trillroofing.com/resources/installation-details/cold-weather-roofing-illinois/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Cold Weather Roofing in Illinois: When It Makes Sense By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Most Illinois roofing happens between April... **Content:** Cold Weather Roofing in Illinois: When It Makes Sense By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Most Illinois roofing happens between April and November – but if your roof fails in January, waiting until spring isn’t always an option. Cold weather roofing is technically possible and sometimes necessary, but it has real tradeoffs that homeowners should understand before committing to a winter install. This guide covers when winter roofing makes sense, what changes about the installation, and how Trill Roofing handles cold-weather work. Why temperature matters Asphalt shingles have a thin strip of factory-applied adhesive on the underside. When shingles are installed and exposed to warm sun, the adhesive softens and bonds the shingle to the one below. This seal-down is what keeps shingles from blowing off in wind events. The seal-down process requires: Direct sunlight for several hours Ambient temperatures above ~40°F A few consecutive days without precipitation or freezing temperatures When these conditions aren’t present, the seal strip stays inert and the shingle doesn’t bond properly. In Illinois winter – typically December through March – those conditions are rare. The cold weather installation problem Two specific issues come up in cold weather roofing: 1. Cracking shingles. Asphalt becomes brittle in cold weather. Below about 40°F, shingles can crack along the nailing zone when bent or nailed. Architectural shingles (thicker, with polymer modification) handle cold better than 3-tab. Below 25°F, even architectural shingles can crack during install – manufacturers recommend not installing at all below this temperature. 2. Seal strip won’t activate. Without seal-down, shingles are held in place only by the nails. Single-shingle wind tolerance drops dramatically – a 130 mph rated shingle might lift in a 30 mph gust if the seal hasn’t activated. The combination means cold-installed shingles… --- ### Roof Pitch and Material Selection \| Trill Roofing - **URL:** https://trillroofing.com/resources/materials-and-shingles/roof-pitch-and-material/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Roof Pitch and Material Selection By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Not every roofing material works on every roof. The slope... **Content:** Roof Pitch and Material Selection By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Not every roofing material works on every roof. The slope (or pitch) of your roof determines which products are viable, which warranties apply, and which installation techniques are required. This guide explains how pitch is measured, the minimum pitch requirements for each common roofing material, and what your options are if your roof falls into the low-slope category. How roof pitch is measured Roof pitch in the US is expressed as rise over run – how many inches the roof rises vertically for every 12 inches of horizontal run. Common pitches: 2/12 – very low slope (2 inches of rise per 12 inches of horizontal). Almost flat to the eye. 4/12 – low to moderate. Typical of ranch homes and additions. 6/12 – standard residential. Most Illinois homes are 5/12 to 7/12. 9/12 – steep. Many Victorian and historic Illinois homes. 12/12 – very steep. 45-degree angle. Beyond 12/12 – extreme. Requires roof jacks, scaffolding, and specialized installation. You can measure your roof’s pitch using a level and a tape measure: hold the level horizontal against the roof for a 12-inch run, then measure the vertical gap at the end. Or measure from inside the attic against the rafter. Asphalt shingle minimum pitch Asphalt shingles – the material on most residential roofs – have a minimum pitch requirement: Below 2/12 – NOT allowed for asphalt shingles. Manufacturer warranties void; the shingles will leak. 2/12 to 4/12 – asphalt shingles allowed only with full coverage of ice and water shield underlayment across the entire roof (not just at eaves and valleys). Special installation, additional cost. 4/12 and above – standard asphalt shingle installation with synthetic underlayment + ice barrier at eaves… --- ### Drip Edge Installation Explained \| Trill Roofing - **URL:** https://trillroofing.com/resources/materials-and-shingles/drip-edge-installation/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Drip Edge Installation: Why It’s Code in Illinois By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Drip edge is L-shaped metal trim installed... **Content:** Drip Edge Installation: Why It’s Code in Illinois By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Drip edge is L-shaped metal trim installed at the eaves and rake edges of a roof. It’s small, inexpensive, and required by the Illinois building code on every residential roof. But on older homes – and on cheap roofing jobs – it’s often missing or installed incorrectly, which causes fascia rot, water damage behind the gutters, and a host of other problems that don’t show up for years. This guide covers what drip edge actually does, the correct install sequence, and how to spot when yours is wrong. What drip edge actually does Drip edge serves three functions on a residential roof: Directs water off the roof and into the gutter (at eaves) – without drip edge, water can wick back under the shingle edge and flow behind the gutter instead of into it Protects the deck edge – the exposed edge of the plywood or OSB decking is vulnerable to water damage; drip edge caps it Provides a clean termination point for the shingles at the rakes (the gable-end edges of the roof) It’s a small, simple component – typically a strip of bent aluminum about 5 inches wide along the eaves and rakes – but the function is critical. Without it, water finds the deck edge and rots out fascia, soffit, and decking over years. Illinois code requirements The International Residential Code, adopted by Illinois (IRC R905.2.8.5), requires drip edge installation: At eaves and rakes of all shingle roofs Minimum 3-inch lap over adjoining pieces Minimum 0.019-inch thick metal (aluminum is most common; galvanized steel and copper also acceptable) Extending at least 1/4 inch below the roof sheathing This is non-negotiable for code compliance on… --- ### How to Choose a Roofing Contractor in Illinois \| Trill Roofing - **URL:** https://trillroofing.com/resources/insurance-and-storm-damage/choose-roofing-contractor-illinois/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** How to Choose a Roofing Contractor in Illinois By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Picking a roofing contractor in Illinois isn’t... **Content:** How to Choose a Roofing Contractor in Illinois By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Picking a roofing contractor in Illinois isn’t always straightforward. Storm season brings out-of-state crews, door-to-door salespeople, and aggressive marketing. Mixed in with them are legitimate local contractors doing solid work – but separating them takes knowing what to ask and what to verify. This guide walks through the Illinois licensing system, the questions that matter, and the red flags that should send you in the other direction. Step 1: Verify the IL license Illinois licenses roofing contractors through IDFPR (Illinois Department of Financial and Professional Regulation) under the Illinois Roofing Industry Licensing Act. Any contractor installing roofs in Illinois must hold an active IDFPR roofing license. To verify a contractor’s license: Go to IDFPR’s public license lookup Search by license number (the contractor should give you this on their first contact) or by business name Confirm the license shows as Active, not Expired or Disciplined Note the license number for your records Trill Roofing carries IL roofing license #104.020330. Active in good standing. You can verify it at the link above. If a contractor: Won’t give you their license number Claims to be “licensed in [other state]” but not specifically IL Has a license that shows Expired or Disciplined …walk away. Unlicensed roofing work has cascading problems with insurance, warranty, and resale. Step 2: Verify insurance Two insurances matter for roofing contractors: General liability insurance: covers damage the contractor causes to your property or surrounding properties. A worker drops a ladder on your siding, a tool damages your neighbor’s car parked nearby – general liability covers it. Workers compensation insurance: covers injuries to the contractor’s employees on your property. Without this, an injury at your house could… --- ### Roof Warranty Types Explained \| Trill Roofing - **URL:** https://trillroofing.com/resources/insurance-and-storm-damage/roof-warranty-types/ - **Published:** 2026-05-12 - **Modified:** 2026-10-05 - **Author:** Andy Pfleger **Summary:** Roof Warranty Types: Manufacturer vs Workmanship vs Labor By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Every roofing quote mentions a warranty. “Lifetime... **Content:** Roof Warranty Types: Manufacturer vs Workmanship vs Labor By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Every roofing quote mentions a warranty. “Lifetime warranty” appears on most premium shingle marketing. The actual coverage is more layered than the marketing suggests, and the differences matter when something goes wrong years later. This guide explains the three main warranty types on residential roofing, what each actually covers, what voids them, and how to evaluate the warranty offer on a specific quote. Type 1: Manufacturer material warranty The shingle manufacturer (GAF, CertainTeed, Owens Corning, etc.) warrants the shingle itself against manufacturing defects. Coverage includes: Material defects – granule shedding outside expected ranges, premature curling, asphalt blistering, color streaking from a manufacturing error Wind warranty – typically 110-130 mph if the shingle was installed with the correct nailing pattern Algae resistance – when applicable (separate 10-year warranty for AR shingles) Standard manufacturer warranties run 30-50 years on architectural shingles, with the term often described as “limited lifetime” – meaning lifetime of the original purchaser, often pro-rated heavily after the first 10-15 years. What manufacturer warranties don’t cover: Damage from wind exceeding the rating Hail damage (insurance handles this) Damage from improper installation (this is why the contractor matters) Damage from inadequate ventilation (most warranties require code-compliant ventilation) Damage from acts of God, falling trees, ice dam leakage from heat loss Manufacturer warranties are usually transferable to one subsequent owner (some require notification to the manufacturer within a window after sale). Type 2: Contractor workmanship warranty Separate from the manufacturer warranty: the roofing contractor warrants their own installation work. This covers errors in installation – incorrect flashing, missed nailing pattern, wrong placement of ice barrier, etc. Workmanship warranty terms vary widely by contractor: 1-2 years – minimal coverage,… --- ### Algae Streaks & Moss on Asphalt Roofs \| Trill Roofing - **URL:** https://trillroofing.com/resources/repair-and-maintenance/algae-moss-roof-removal/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Algae Streaks & Moss on Asphalt Roofs: Removal and Prevention By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor The dark streaks running down... **Content:** Algae Streaks & Moss on Asphalt Roofs: Removal and Prevention By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor The dark streaks running down asphalt roofs are everywhere in Illinois – especially on north-facing slopes and shaded sections. They’re not dirt, not dirt stains, and not always harmless. This guide explains what’s actually growing up there, when it’s purely cosmetic vs. when it’s shortening shingle life, how to remove it safely, and how to prevent it from coming back when you re-roof. What’s actually growing on your shingles The dark streaks are caused by Gloeocapsa magma – a type of blue-green algae (cyanobacteria) that feeds on the limestone filler in standard asphalt shingles. The algae thrives in moist, shaded conditions and produces a dark pigment that becomes visible as the colony grows. The streaks typically run vertically down the roof slope, are darker at the top (where moisture lingers near the ridge), and most pronounced on: North-facing slopes (less direct sun, slower drying) Slopes under tree cover or in shade from neighboring buildings Older roofs (5+ years) where granule wear has exposed more limestone filler Coastal or humid regions – and Illinois summers easily qualify Moss is a separate organism – true plants that root into the shingle surface and grow as green cushions, typically in heavily shaded areas. Moss is much more damaging than algae because it physically lifts shingles and traps moisture against the deck. Cosmetic vs damaging Algae staining is mostly cosmetic. The algae feeds on filler material, not on the asphalt itself, so it doesn’t directly shorten shingle life. However: The dark color absorbs more heat, increasing thermal stress on the shingles below – speeding asphalt aging The algae layer traps moisture against the shingle, accelerating granule loss over years… --- ### Soffit & Fascia Repair \| Trill Roofing - **URL:** https://trillroofing.com/resources/repair-and-maintenance/soffit-fascia-repair/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Soffit & Fascia Repair: When Wood Rots at the Eaves By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Soffit and fascia are two... **Content:** Soffit & Fascia Repair: When Wood Rots at the Eaves By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Soffit and fascia are two of the most overlooked exterior components of a home – until something goes wrong. They sit at the eaves of the roof and quietly do critical jobs: keeping water out of the wall cavity, providing intake ventilation for the attic, and finishing the roof line cleanly. When they fail, it’s almost always because of water – either from above (gutter back-up, missing drip edge) or from below (humidity issues with poor attic ventilation). What soffit and fascia actually are Fascia is the vertical board running along the eave edge of the roof – the board that the gutter attaches to. On most Illinois homes it’s a 1×6 or 1×8 board, traditionally painted wood, sometimes wrapped in aluminum coil stock. The fascia caps the ends of the roof rafters and provides the mounting surface for the gutter. Soffit is the horizontal panel running underneath the eave overhang – the surface you see when you look up at the roof from below. Soffit can be wood, aluminum, vinyl, or fiber cement. It encloses the underside of the eave overhang and typically has vent perforations to allow air into the attic for intake ventilation. Both components together create the structural and visual termination of the roof at the eaves, and both contribute to attic ventilation when properly installed. Why they fail Common failure modes for soffit and fascia on Illinois homes: Gutter back-up. Clogged gutters overflow, water runs down behind the gutter against the fascia, and the wood gets saturated repeatedly. Over years, the fascia rots, paint peels, and eventually the wood becomes too soft to hold the gutter mounting brackets. Missing drip… --- ### Chimney Flashing Repair \| Trill Roofing - **URL:** https://trillroofing.com/resources/repair-and-maintenance/chimney-flashing-repair/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Chimney Flashing Repair: How It’s Done Right By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Chimney leaks are one of the most common... **Content:** Chimney Flashing Repair: How It’s Done Right By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Chimney leaks are one of the most common roof complaints in Illinois homes. The leak shows up as a stain on the ceiling near the chimney chase, or as moisture inside the firebox. The fix is rarely as simple as “caulk the gap.” Proper chimney flashing is a four-component system – when any one of those components fails, water finds its way in. This guide walks through the components, common failure modes, and what proper repair looks like. Chimney flashing – the four components Every masonry chimney rising through a sloped roof should have these four flashing zones, each of which is a distinct piece of metal: Base flashing – single piece of metal at the downhill side of the chimney that catches water flowing toward the chimney from above. Bent up against the chimney face and out under the shingles below. Step flashing – running up both sides of the chimney parallel to the roof slope. Same principle as sidewall step flashing on dormers: one piece between each shingle course, stepping up the chimney. Cricket (or saddle) – a small roof-like structure built into the back (uphill) side of wider chimneys (more than ~30 inches wide) to divert water around the chimney instead of letting it pool against the brick. Smaller chimneys can sometimes skip the cricket but wider chimneys always need one. Counter-flashing – the upper layer of metal that’s set into a kerf cut in the chimney’s mortar joints, then bent down over the top edge of the step flashing and base flashing. This is what prevents water from running behind the step flashing from above. All four components have to be present and properly… --- ### Madison County Roofing Permits \| Trill Roofing - **URL:** https://trillroofing.com/resources/installation-details/madison-county-roofing-permits/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Madison County Roofing Permits: What’s Required By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Roofing work in Madison County, Illinois requires building permits... **Content:** Madison County Roofing Permits: What’s Required By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Roofing work in Madison County, Illinois requires building permits in most circumstances, and the specific authority – city, village, or county – varies depending on where your home sits. This guide walks through who issues permits for which areas, when a permit is required (and when it isn’t), what the inspection process looks like, and what your contractor should handle so you don’t have to chase paperwork. When a permit is required Madison County and the cities/villages within it generally require a building permit for: Full roof replacement (tear-off and re-shingle) – always requires a permit Re-roofing with overlay (new shingles over existing) – generally requires a permit Roof repair affecting structural members – replacing rafters, decking sections, or structural sheathing Adding skylights, chimneys, or roof penetrations Permits are not typically required for: Shingle repair affecting a small area (a few shingles, single penetration flashing) Gutter and downspout work (separate scope) Soffit and fascia repair on existing geometry The threshold varies by jurisdiction. When in doubt, your contractor should know and pull the permit anyway – the penalty for unpermitted work is significantly more expensive than the permit itself. Who issues the permit (by location) Madison County is divided between municipal building departments and the county building department. Where your home sits determines who handles the permit: Location Permit authority Within city limits of Alton, Edwardsville City building department Within village limits of Bethalto, Brighton, East Alton, Glen Carbon, Godfrey, Wood River, Worden, etc. Village building department + Madison County (varies by village) Unincorporated Madison County Madison County Building Code Enforcement The Village of Godfrey specifically requires permits through Madison County’s building code enforcement office for roofing work, with… --- ### What a Real Roof Inspection Includes \| Trill Roofing - **URL:** https://trillroofing.com/resources/repair-and-maintenance/what-roof-inspection-includes/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** What a Real Roof Inspection Includes (vs a Sales Call) By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor “Free roof inspection” means different... **Content:** What a Real Roof Inspection Includes (vs a Sales Call) By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor “Free roof inspection” means different things from different contractors. For some it’s a 10-minute walk-around looking for problems to sell you on. For others it’s a 90-minute technical assessment that produces a written report you could use to file an insurance claim or get a second opinion. This guide explains what a real roof inspection covers, what a sales-call “inspection” looks like, and how to tell the difference before you let someone on your roof. What a real inspection includes A proper residential roof inspection from a qualified contractor includes: Exterior walk-around – perimeter of the home, evaluating soft metals (gutters, AC fins, deck furniture) for impact marks, checking soffit and fascia condition, looking for water staining patterns on siding Roof access – actually walking the roof (or carefully inspecting from a ladder/drone for steep pitches or compromised structures) Slope-by-slope shingle assessment – examining each roof slope for hail bruising, granule loss, lifted or missing shingles, curling, blistering Test squares – marking a 10 ft x 10 ft test area on representative slopes and counting impact damage if hail is suspected Flashing inspection – step flashing at sidewalls, valley flashing, chimney counter-flashing, pipe boots, drip edge, ridge cap. Each gets evaluated separately because each fails differently. Penetration check – every plumbing vent, vent fan, chimney, skylight, satellite mount inspected for sealant condition and water staining Attic inspection – entering the attic to look at the underside of the roof deck for water staining, mold, frost damage, evidence of inadequate ventilation Ventilation evaluation – counting intake (soffit) and exhaust (ridge, gable, box) vents, calculating NFA, identifying mixed-exhaust issues Photo documentation – 30-60 photos covering every slope,… --- ### Ridge Vent vs Box Vent vs Power Fan \| Trill Roofing - **URL:** https://trillroofing.com/resources/installation-details/ridge-vent-vs-box-vent/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Ridge Vent vs Box Vent vs Power Fan: Roof Exhaust Compared By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor If you’re getting a... **Content:** Ridge Vent vs Box Vent vs Power Fan: Roof Exhaust Compared By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor If you’re getting a roof replaced or troubleshooting an attic that’s too hot in summer and condenses moisture in winter, the question of which exhaust ventilation strategy to use comes up. There are three real options: continuous ridge vent, box vents (also called turtle vents or static vents), or powered ventilation. Each has tradeoffs. This is what we install and why. How attic exhaust ventilation works Attic ventilation is a continuous airflow system: cool air enters at the soffits (intake), travels up through the attic, and exits at the highest point of the roof (exhaust). The driving force is the stack effect – warm air rises naturally, creating low pressure at the soffits that pulls in cooler outside air. Exhaust ventilation only works if intake is balanced. Without enough soffit intake, the exhaust pulls air from wherever it can – including from the conditioned space below through gaps in the attic floor. This wastes energy and can pull humid living-space air into the attic. For more on the calculation side, see our attic ventilation sizing guide. This piece focuses on the exhaust hardware choices. Continuous ridge vent – what we install on most homes A continuous ridge vent runs along the entire length of the roof’s ridge line. The ridge cap shingles cover and protect it from above; the slot beneath allows air to exit. Pros: Even exhaust along the entire ridge – the attic ventilates uniformly rather than from a single point Highest effective exhaust point – physics of the stack effect work best when exhaust is as high as possible Aesthetically clean – visible profile is just a slightly raised ridge cap,… --- ### Wind Uplift Ratings for IL Roofs \| Trill Roofing - **URL:** https://trillroofing.com/resources/materials-and-shingles/wind-uplift-ratings-illinois/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Wind Uplift Ratings for Illinois: Class F, G, H Explained By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Every architectural asphalt shingle sold... **Content:** Wind Uplift Ratings for Illinois: Class F, G, H Explained By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Every architectural asphalt shingle sold in the US carries a wind uplift rating – Class A, F, G, or H. The number indicates how much wind speed the shingle is rated to withstand before the seal strip fails and shingles start lifting off the deck. For Illinois homes – which sit in an active wind corridor – the rating that goes on the roof is one of the more consequential spec decisions in a replacement project. What wind uplift testing actually measures Asphalt shingle wind ratings come from two standard test methods: ASTM D3161 – older standard. Mounts shingles on a deck and blows air at increasing speeds for 2 hours per speed level. Pass criteria: no shingles lift more than slightly from the deck. Class A – 60 mph (essentially no wind warranty) Class D – 90 mph Class F – 110 mph ASTM D7158 – newer (2008+) and more rigorous. Tests for the full structural integrity of the seal strip under sustained wind. Most premium shingles today carry D7158 ratings: Class D – 90 mph design wind speed Class G – 120 mph design wind speed Class H – 130 mph design wind speed Class H (D7158) is the highest rating commonly available on residential asphalt shingles. Almost all current premium architectural lines hit Class H – GAF Timberline HDZ, CertainTeed Landmark, Owens Corning Duration. Wind speeds Illinois actually sees The IRC-derived basic wind speed for Madison County is approximately 115 mph (3-second gust). This is the design wind speed for new construction in the IRC – the speed an engineered structure is required to handle.

It’s the second line of defense – when wind-driven rain or ice dam meltwater finds its way past the shingles, the underlayment is what stops the water from reaching the deck. For decades, the standard was 15-lb felt (“tarpaper”). Today, synthetic underlayment is the right answer on virtually every Illinois install. Here’s why, with the technical specs. What underlayment does Underlayment serves four functions in a properly installed roof system: Backup water barrier – water that gets past the shingles (lifted in wind, meltwater under ice dam, condensation drip) hits the underlayment before reaching the deck Deck protection during install – when shingles are off mid-installation and an afternoon storm rolls in, underlayment keeps the deck dry for the rest of the project Smoothing layer – underlayment evens out small imperfections in the deck so the shingles lie flat Vapor management – modern synthetics allow some vapor to pass while blocking liquid water Ice and water shield (a self-adhered rubberized membrane) is a different product – installed in valleys, at eaves, and around penetrations. Underlayment covers the rest of the deck. Both are required by IL code in different zones. 15-lb felt – the old standard Asphalt-saturated felt (“15-lb felt” or “tarpaper”) was the default underlayment for residential roofs through the 1990s. It’s still widely available, still inexpensive, and still occasionally installed by contractors looking to shave dollars off a quote. Felt specs: Weight: 15-lb felt is actually about 8 lbs per 100 sq ft (the “15-lb” name is historical and inaccurate). 30-lb felt is heavier – maybe 16 lbs per… --- ### Roof Maintenance Schedule for Illinois Homes \| Trill Roofing - **URL:** https://trillroofing.com/resources/repair-and-maintenance/roof-maintenance-schedule/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Roof Maintenance Schedule for Illinois Homes By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Roofs that get inspected and maintained on a schedule... **Content:** Roof Maintenance Schedule for Illinois Homes By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Roofs that get inspected and maintained on a schedule typically last 30-50% longer than roofs that get attention only when something obvious goes wrong. The reason: most roof failures start small and slow. A pipe boot starts cracking at year 8 but doesn’t leak until year 12 – by then, water has been wicking into the decking for a year. Catching that boot at the year-8 inspection costs $300. Letting it go costs $3,000 in interior repairs and decking replacement. This guide is the seasonal maintenance schedule we recommend for Illinois homes. It assumes a standard asphalt-shingle residential roof. Spring (March-May) – post-winter assessment Spring is the most important inspection of the year for Illinois roofs. Winter freeze-thaw, ice dams, snow load, and wind events accumulate damage that needs to be documented and addressed before summer storm season. What to look at: Walk the perimeter and check the gutters for granule accumulation (a small amount is normal; piles in the downspouts suggest accelerated shingle wear) Inspect the soffit and fascia for water staining or rot (especially at the eaves where ice dams form) Look up at the roof from each side of the house with binoculars; note any obviously lifted, missing, or out-of-place shingles Check the attic in the morning for water stains on rafters or decking (winter condensation issues show up here) Look at the chimney mortar joints from the ground – cracked or missing mortar lets water in even with good flashing What to schedule: Free professional roof inspection if it’s been over 18 months since the last one Storm damage claim assessment if you suspect a winter wind or ice event caused damage (IL has a… --- ### Roof Decking: OSB vs Plywood \| Trill Roofing - **URL:** https://trillroofing.com/resources/materials-and-shingles/roof-decking-osb-vs-plywood/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Roof Decking: OSB vs Plywood and When to Replace By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Roof decking is the sheet material... **Content:** Roof Decking: OSB vs Plywood and When to Replace By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Roof decking is the sheet material – plywood or OSB – that’s nailed to the roof rafters. The shingles, underlayment, ice barrier, and flashing all attach to it. When decking goes soft or rotted, the roof system above it has nothing solid to hold onto, and shingles pull free even in moderate wind. This guide explains the differences between OSB and plywood decking, when decking needs replacement, and what to expect during a Trill Roofing tear-off when soft spots are found. OSB vs plywood – what’s actually different Both materials are wood-based panels glued and pressed into 4×8 sheets. The differences: Plywood: Made from thin layers (“plies”) of wood veneer cross-laminated for strength Common in residential construction from the 1950s through about 1990 More expensive than OSB Generally heavier When exposed to moisture and then dried, plywood delaminates but retains most structural strength Holds nails very securely OSB (Oriented Strand Board): Made from wood strands oriented in layers and bonded with adhesive Standard since the early 1990s – most Illinois homes built since then have OSB decking Less expensive than plywood Lighter When exposed to prolonged moisture, OSB swells and loses structural strength permanently Holds nails well but slightly less than plywood For roof decking purposes, both materials are acceptable when properly installed and protected from moisture. The bigger variable is age and exposure history. How decking fails Roof decking has one job: stay dry. When it doesn’t, several failure modes appear: Soft spots from chronic leaks. A failed pipe boot, flashing, or roof valley can leak slowly for years without showing up inside the house – the water gets absorbed by the decking. The wood… --- ### Roof Insurance Claim Documentation \| Trill Roofing - **URL:** https://trillroofing.com/resources/insurance-and-storm-damage/roof-insurance-claim-documentation/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Roof Insurance Claim Documentation: What You Need By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Filing a roof storm damage claim in Illinois... **Content:** Roof Insurance Claim Documentation: What You Need By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Filing a roof storm damage claim in Illinois follows a clear documentation process. The homeowners who get full and fair settlements are the ones with thorough documentation up front, not the ones who fight after the initial scope comes back low. This guide walks through what documentation actually gets submitted, what carriers look for, the 2-year IL claim deadline, and where Trill Roofing fits in. The 2-year deadline in Illinois Illinois statute (215 ILCS 5/143.1) gives policyholders 2 years from the date of loss to file a property damage claim. “Date of loss” means the date of the storm event, not the date you discover the damage. If you’re trying to claim damage from a storm 26 months ago, the carrier will deny on timeliness – even if the damage is real and obvious. Practical implications: If you suspect damage from a recent storm, file within months, not years If you have damage you think might be older, look up NOAA storm data for the past 24 months to identify candidate events For damage that’s been accumulating from multiple events, file against the most recent applicable storm NOAA storm data – establishing the event Carriers want a verifiable storm event corresponding to your claim date. The standard reference is NOAA’s Storm Events Database, which records: Date, time, and location of severe weather events Hail size (when measurable) Wind speed (when measurable) Spotter reports and damage reports for the affected area For Madison County (Godfrey, Alton, Edwardsville, etc.), NOAA data is searchable by county and zip code. We pull this data for every storm claim and include the relevant events in the damage report.

Adjusters and contractors look at the same indicators in the same order. This guide walks through how a hail damage roof assessment is actually done – what witness marks are, how test squares work, the difference between cosmetic granule loss and a real claim, and what a homeowner can do (and shouldn’t do) before the adjuster shows up. What hail does to an asphalt roof Hail damage to asphalt shingles takes two forms: 1. Bruising (the real damage). A hailstone strike compresses the granules into the asphalt mat below and can crack the fiberglass reinforcement layer underneath. From the surface it looks like a circular dark spot (where granules were displaced) but the structural damage is the cracked mat. Bruises don’t always leak immediately – many sit for 6-18 months before water finds the crack and starts traveling under the shingle. 2. Granule loss without bruising (often cosmetic). Hail can knock granules off the surface without cracking the underlying mat. The shingle looks worse but it’s still structurally sound. This is the gray area: granule-loss-only damage shortens shingle life (UV breaks down the asphalt faster without granules protecting it) but doesn’t cause immediate leaks. The line between “bruise that warrants a claim” and “cosmetic granule loss” is what every assessment is trying to draw. Witness marks – confirming a hail event hit your address Before evaluating the shingles, both contractors and adjusters look at “soft metals” on the property – items that hail dents easily and definitively. These include: Aluminum gutters and downspouts (dents in… --- ### Tear-Off vs Overlay: Why We Always Tear Off \| Trill Roofing - **URL:** https://trillroofing.com/resources/installation-details/tear-off-vs-overlay/ - **Published:** 2026-05-12 - **Modified:** 2026-10-05 - **Author:** Andy Pfleger **Summary:** Tear-Off vs Overlay: Why We Always Tear Off By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor If you’re getting roofing quotes, you might... **Content:** Tear-Off vs Overlay: Why We Always Tear Off By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor If you’re getting roofing quotes, you might see two options: tear off the old shingles and install new ones, or “overlay” – install new shingles directly over the existing layer. Overlay is cheaper upfront. It also costs you more in the long run, voids most warranties, and hides decking damage that turns into bigger repairs later. This is why Trill Roofing always tears off – even when it’s not the cheapest line item on the quote. What Illinois code allows The Illinois adoption of the International Residential Code (IRC R908) allows up to two layers of asphalt shingles on a residential roof. So if your current roof has one layer of shingles, overlay is technically legal. If it already has two layers, code requires tear-off – you can’t add a third. Some local jurisdictions (City of Edwardsville, parts of Madison County) have additional restrictions, and HOA covenants in some subdivisions prohibit overlay regardless of code. Always confirm local rules before quoting overlay. Why overlay is the wrong call (almost always) Here’s what overlay actually does to your roof system: 1. It hides decking damage. The single most important reason to tear off: you can’t inspect the roof decking without removing the shingles. Soft spots, rotted plywood, ice dam damage at the eaves, water damage around chimneys – none of these are visible from above the shingles. Overlay puts new shingles over decking that may need replacement. A few years later, when the soft spot fails and you get a leak, the fix is to tear off the new shingles, replace the deck, and re-shingle. You pay twice. 2. It compounds underlayment problems. The original underlayment under the… --- ### Roof Flashing Explained \| Trill Roofing - **URL:** https://trillroofing.com/resources/installation-details/roof-flashing-explained/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Roof Flashing Explained: Step, Valley, Chimney, Pipe, Drip Edge By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Ninety percent of roof leaks we... **Content:** Roof Flashing Explained: Step, Valley, Chimney, Pipe, Drip Edge By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Ninety percent of roof leaks we see start at flashing, not at the shingles themselves. Shingles are the visible part of the roof – but it’s the metal flashing at every penetration, every sidewall, every valley, every chimney, and every eave that actually keeps water out. This guide walks through each flashing type, how it works, how it fails, and what to look for during an inspection. Step flashing – sidewalls Step flashing protects the joint where a sloped roof meets a vertical wall (most commonly a dormer sidewall or where a single-story addition meets a two-story house). The name comes from the installation pattern: an L-shaped piece of bent metal sits between each shingle course, with one leg up the wall and one leg flat on the roof, “stepping” up the roof slope. Why it’s the right design: water flowing down the wall hits the upturned leg and is redirected onto the next shingle below. Water flowing down the roof slides over the flat leg and is shed off the eave. How it fails: Caulk-only installations (no metal step flashing – just sealant in the wall-roof joint) fail within 2-5 years as the caulk cracks Step flashing covered by stucco or siding that doesn’t have proper kick-out flashing at the bottom of the wall directs water into the wall cavity instead of out Bent or corroded step flashing from prior repair attempts Reused step flashing during shingle replacement (when it should have been replaced) Every Trill Roofing replacement includes new step flashing at sidewalls, with proper kick-out flashing at the bottom of any wall-roof intersection to direct water away from the building. Valley flashing –… --- ### Ice Dam Prevention for Illinois Homes \| Trill Roofing - **URL:** https://trillroofing.com/resources/insurance-and-storm-damage/ice-dam-prevention/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Ice Dam Prevention for Illinois Homes By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Every winter we get calls from Illinois homeowners with... **Content:** Ice Dam Prevention for Illinois Homes By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Every winter we get calls from Illinois homeowners with active ceiling leaks where the cause is an ice dam at the eave. By the time the leak shows up inside, the ice has been building for days or weeks and water is backing up under the shingles. This guide explains what actually causes ice dams, why the common “fix” (heat cable along the gutter line) is a band-aid, and what prevention looks like when done right. How ice dams form Ice dams are a heat-loss problem, not a snow problem. The mechanism: Snow accumulates on the roof. Heat escapes from the conditioned space below through the attic floor (insulation gaps, air leaks, recessed lights, attic hatch). That heat warms the underside of the roof deck above the heated portion of the house. The warm deck melts snow on the upper portion of the roof. Water flows down the roof slope. When the water reaches the eave overhang – which is over unheated space and stays at outside air temperature – it refreezes. Ice accumulates along the eave, growing into a dam. More meltwater backs up behind the dam, finds the gap between shingles, and works under them. Water hits the roof deck, runs along the underside, and shows up inside. The dam itself is just the symptom. The underlying problem is uneven roof-deck temperature: warm above the heated space, cold above the eave overhang. Why “heat cable along the gutter” doesn’t fix it The most common “DIY” ice dam fix is heat cable installed in a zigzag pattern along the bottom 3-4 feet of the roof. It works in a narrow sense – it melts the ice in the… --- ### Attic Ventilation Sizing for Illinois Roofs \| Trill Roofing - **URL:** https://trillroofing.com/resources/installation-details/attic-ventilation-sizing/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Attic Ventilation Sizing for Illinois Roofs By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR \#104.020330 · GAF Certified Contractor Most roof warranty failures we see trace back to... **Content:** Attic Ventilation Sizing for Illinois Roofs By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Most roof warranty failures we see trace back to one thing: bad attic ventilation. Shingles that should last 30 years curl and lose granules in 12. Plywood decking rots. Ice dams form along the eaves every winter. Energy bills creep up. All from an attic that doesn’t breathe right. This guide walks through how attic ventilation actually works, how to calculate the right amount for your roof (the “NFA” calculation), and what gets specified incorrectly on most Illinois homes. How attic ventilation works Attic ventilation is a continuous airflow system: cool outside air enters at the soffits (intake), travels up through the attic, and exits at or near the ridge (exhaust). The driving force is the stack effect – warm air rises, creating low pressure at the soffits that pulls in cooler air. When this works: In summer: hot air doesn’t accumulate in the attic. Cooling load drops. Shingles run cooler, so the asphalt doesn’t soften and curl. In winter: warm air escaping from the conditioned space below doesn’t get trapped. The roof deck stays cold, which prevents ice dams (more on that below). Year-round: moisture from cooking, bathing, and laundry doesn’t condense on the underside of the roof deck. When it doesn’t work – undersized, unbalanced, or short-circuited – every one of those failure modes shows up. The NFA (Net Free Area) calculation Building codes (including the International Residential Code adopted by Madison County and most IL jurisdictions) require a minimum attic ventilation ratio of 1:300 – meaning 1 square foot of net free vent area for every 300 square feet of attic floor area, when intake and exhaust are roughly balanced (50/50 split). Without balanced intake, the… --- ### Class 4 Impact-Resistant Shingles in Illinois \| Trill Roofing - **URL:** https://trillroofing.com/resources/materials-and-shingles/class-4-impact-resistant-shingles/ - **Published:** 2026-05-12 - **Modified:** 2026-05-13 - **Author:** Andy Pfleger **Summary:** Class 4 Impact-Resistant Shingles in Illinois: Worth It?

By Andy Pfleger, Owner & Licensed RooferIllinois Roofing License IDFPR #104.020330 · GAF Certified Contractor Class 4 impact-resistant shingles cost a few hundred dollars more upfront than standard architectural shingles, and in Illinois – where hail is part of the weather pattern – they usually pay that back via your homeowner insurance discount in 3-7 years. Here’s what Class 4 actually is, how the UL 2218 test works, what discount you’ll see from State Farm / Allstate / Farmers / American Family, and the simple math on whether they pencil out for your home. What “Class 4” actually means The Class 4 designation comes from UL 2218 – a standardized impact-resistance test where steel balls are dropped onto a shingle from a fixed height. The shingle is then inspected for cracks in the underlying mat: Class 1: 1.25″ steel ball (about marble size) Class 2: 1.5″ steel ball Class 3: 1.75″ steel ball Class 4: 2.0″ steel ball (golf ball size) To pass Class 4, the shingle has to survive two strikes from a 2-inch steel ball in the same spot without the mat cracking. That’s hail-event level impact. Class 4 shingles look identical to standard architectural shingles on the roof. The difference is in the asphalt – it’s modified with polymers (typically SBS rubber, sometimes APP plastomer) that make the shingle flexible enough to absorb impact without cracking. Why this matters in Illinois The Riverbend, Madison County, and most of central/southern Illinois sit inside what NOAA classifies as a “hail alley” – the broad zone from Texas through the Plains into the Midwest where hail-producing storms are most frequent. Madison County averages 2-4 measurable hail events per year, with the major events (1.5″+ hailstones) hitting every 3-5 years. Standard architectural shingles… --- --- # Navigation - [Section Overview](https://trillroofing.com/resources/llms.txt): Return to Resources section index - [Main Documentation](https://trillroofing.com/llms.txt): Return to main site documentation - [Main Full Content](https://trillroofing.com/llms-full.txt): Complete detailed content for the entire site ## Other Sections - [Services Section](https://trillroofing.com/services/llms.txt): Overview of the services section - [Services Full Content](https://trillroofing.com/services/llms-full.txt): Detailed content for the services section - [Service-areas Section](https://trillroofing.com/service-areas/llms.txt): Overview of the service-areas section - [Service-areas Full Content](https://trillroofing.com/service-areas/llms-full.txt): Detailed content for the service-areas section Main site guide: https://trillroofing.com/llms.txt
