If your Trill Roofing replacement is scheduled, this guide walks through exactly what happens on install day – from the time the crew arrives to the final cleanup. 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. Old materials drop into a dumpster positioned on the driveway (or sometimes thrown directly to ground tarps and shoveled into the dumpster).
Noise level: Loud. Shingle hammers, occasional sawing for stubborn nails, debris hitting the dumpster. If you’re sensitive or work from home, plan to be elsewhere or use noise-cancelling.
What you’ll see: Crew of 4-6 people on the roof simultaneously, dumpster filling rapidly, your roof looking exposed and weathered down to plywood.
Inside the house: Some dust falls from rafters into the attic. If you have anything in the attic that’s dust-sensitive, cover it before install day. Ceiling fixtures and skylights occasionally vibrate from impact.
Decking inspection – 11:00 AM to 11:30 AM
Once tear-off is complete, the crew foreman walks the entire deck. Any soft or rotted sections are marked with spray paint. The foreman calls you (or knocks on the door) with a summary:
- How many sheets of decking need replacement
- Cost (we charge our cost on the material – no markup)
- Approval to proceed
You approve verbally; the cost is added to the final invoice. For most Riverbend homes this is 0-5 sheets. Major decking replacement (10+ sheets) is rare on homes built after 1990.
Install – 11:30 AM to 4:00 PM
This is the rebuild phase, in order:
- Replace damaged decking sheets where marked
- Install ice and water shield at eaves (24″ inside warm-wall line), in valleys, around all penetrations
- Roll out synthetic underlayment across remaining deck
- Install new drip edge at eaves and rakes
- Install starter strip course
- Install field shingles, working from eave up the slope (one slope at a time)
- Install step flashing at sidewalls as shingle courses progress
- Replace chimney counter-flashing if needed (kerf the brick mortar, insert new metal, re-mortar)
- Install new pipe boots at each penetration
- Install ridge cap shingles at the ridge line
Noise reduces during this phase – mostly nail guns, which are short bursts rather than continuous hammering. Most of a typical 2,000 sq ft installation finishes today.
Cleanup – 4:00 PM to 5:30 PM
End-of-day cleanup is non-negotiable:
- Tarps and plywood folded up
- Magnetic sweep across the driveway, yard, sidewalks (twice – once close to the house, once at the perimeter)
- Gutters cleaned of debris from the install
- Property walk-around with the crew foreman to identify anything missed
- Dumpster pickup scheduled (typically the day after install)
If anything was damaged during install (rare but possible – a shrub trampled, a gutter dented), we identify and quote the repair before the crew leaves.
Multi-day installs
Most Trill Roofing residential installs complete in one day. Two-day installs happen when:
- Roof is over 3,500 sq ft
- Roof has complex geometry (lots of valleys, dormers, multiple chimneys)
- Significant decking replacement adds time
- Weather window closes mid-job and forces a wrap
If the install will be multi-day, we cover any exposed deck with synthetic underlayment overnight so a passing storm doesn’t reach the inside. We always leave the roof watertight at the end of any working day, regardless of where the install is in progress.
After install – the final week
Within a few days of install:
- Final inspection – Madison County or village inspector checks the work. We coordinate the appointment; you don’t need to be home unless your jurisdiction requires it.
- Manufacturer warranty registration – We submit registration with GAF (or CertainTeed / Owens Corning) within 60 days. You receive a registration certificate by email.
- Final invoice – Includes the agreed scope plus any decking replacement approved during install.
- Follow-up call – Our project manager calls to confirm satisfaction and answer any questions about the work.
