Asphalt Shingle Roofing in Grafton, IL

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 Grafton home

Grafton’s riverfront location means high humidity, more sun exposure on south-facing slopes, and a history of major Mississippi flood events. Homes above the floodplain are typical roofing work; homes within the flood zone may have additional considerations for water-resistant material choices.

Grafton homes near the river often have heavier moss and algae growth on north and shaded slopes – algae-resistant shingles (with copper or zinc granules) are worth the small upgrade cost here.

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.
