Asphalt shingles are the right material for almost every East Alton home – they handle Illinois freeze-thaw and hail better than wood shake, last longer than 3-tab, and don’t carry the upfront cost of metal. Trill Roofing installs architectural and impact-resistant asphalt shingles from GAF, CertainTeed, and Owens Corning across East Alton and the Riverbend.
Architectural vs. 3-tab vs. impact-resistant
Three categories of asphalt shingle, very different products:
3-tab – the old standard. Thin, single-layer, lower wind rating (typically 60 mph). Cheapest but shortest lifespan. We don’t recommend 3-tab on new installs in the Riverbend because our wind events outpace what the shingle can handle.
Architectural (dimensional, laminate) – the workhorse. Multiple layers fused together, Class H wind rating (130 mph), 30 to 50 year manufacturer warranty. About 80% of our installs use this category. Examples: GAF Timberline HDZ, CertainTeed Landmark, Owens Corning Duration.
Class 4 impact-resistant – same architectural design but with a polymer-modified asphalt core that resists hail. Passes UL 2218 Class 4 testing (highest rating). State Farm, Allstate, Farmers, and American Family typically offer a 5-25% IL homeowner premium discount when you install Class 4. Adds about $0.50-$0.85/sq ft over standard architectural.
What shingle to pick for a East Alton home
Post-war housing in East Alton often has the original roof decking – 1/2-inch plywood or 1×8 lumber sheathing – that’s been through 60+ years of moisture cycling. Decking replacement is a more common line item here than in newer subdivisions.
Older East Alton homes commonly have soft decking around vent penetrations and chimneys; we check sheathing condition carefully on every replacement quote in this village.
GAF Certified – what it means for your install
Trill Roofing is a GAF-certified contractor. What it means for you:
- Extended manufacturer labor warranty on your install (typically 25-50 years vs. the standard 10-25)
- Material defect coverage that doesn’t depend on us being in business – GAF stands behind the warranty directly
- Quarterly installation audits – GAF spot-checks our work to keep the certification
- Access to GAF’s premium product lines (Golden Pledge, System Plus) that aren’t sold to non-certified contractors
If you go with CertainTeed or Owens Corning instead, we still pull manufacturer-certified status on those lines.
