Grand Chain Roofing Contractor

Owens Corning Duration shingles with SureNail technology rated to ASTM D3462 and D7158 Class H wind resistance. Our Grand Chain crews install TruDefinition Duration in a full Owens Corning system. ProArmor synthetic underlayment, VentSure ridge vent, and Starter+ starter strip. Preferred Protection warranty included.

Missing shingles cause water intrusion through the exposed underlayment and decking. We don't just replace the missing shingle. We check the deck for moisture damage with a Protimeter pin meter, replace any compromised underlayment, and weave new CertainTeed Landmark shingles into the existing pattern.

We work with every major insurance carrier. State Farm, Allstate, USAA, Liberty Mutual, Farmers, Nationwide. Our supplement team knows Xactimate line items and fights for full replacement when your roof qualifies.

A new roof installation starts with getting the specs right. Roof pitch determines your material options. Attic space determines ventilation needs. Local code determines underlayment requirements. We handle all of that before the first shingle goes on.

We install 24-gauge and 26-gauge standing seam in Galvalume and pre-painted steel. Concealed fastener system means nothing's exposed to weather. Panels lock together at the seam and clip to the roof deck.

GAF Timberline HDZ architectural shingles with StrikeZone nailing area. The highest-selling shingle in North America. Impact-rated to UL 2218 Class 4 when installed with the full GAF Roof System. Our Grand Chain crews install Timberline in the full system configuration to qualify for Golden Pledge warranty. ASTM D3462 and D7158 Class H certified.

Modified bitumen is our go-to for residential flat roofs in Grand Chain. Two-ply torch-applied system with a granulated cap sheet. It handles foot traffic, thermal cycling, and Illinois UV better than single-ply at the residential scale.

Our Grand Chain commercial crews handle everything from small retail strip centers to 50,000 sq ft warehouses. TPO, EPDM, modified bitumen, metal. We're certified installers for all major commercial membrane systems.

If your gutters overflow during rain, they're either clogged, undersized, or pitched wrong. Sometimes all three. We'll assess the issue and fix it. Might be a cleaning, might be a replacement.

Our Grand Chain roof inspections cover shingles, flashing, pipe boots, ridge vent, soffit, gutters, and decking condition. You get a written report with photos. If nothing's wrong, we tell you that.

After we tarp and secure your roof, we document everything for insurance purposes. Photos, measurements, damage descriptions. Your adjuster gets a professional report, not a handwritten note.

A skylight installed wrong will leak. The flashing has to integrate with the shingle courses. Step flashing on the sides, headwall flashing on top, and a sill pan underneath. We use manufacturer flashing kits because they're engineered to work with the skylight frame.
