GAF + Elevate (formerly Firestone) certified for TPO, EPDM, modified bitumen and PVC. Single-ply mechanically attached or fully adhered, up to 200,000 sq ft. 20-year manufacturer NDL warranties on qualifying installs.
Commercial roofing is a different discipline. Rooftop HVAC, through-deck penetrations, drain slopes, fire code, and a warranty that the manufacturer — not just the contractor — has to underwrite. Facility managers and building owners need a roofer who understands the building as a system and the claim as a document.
We carry the two certifications that unlock manufacturer-backed No-Dollar-Limit warranties: GAF Certified Commercial Installer and Elevate (Firestone) Red Shield. Most Chicago-area commercial roofers carry one. Very few carry both.
The right system depends on the building's use, foot traffic, insulation target, and warranty term.
A No-Dollar-Limit warranty means the manufacturer covers the full cost of any covered repair for the full term, regardless of amount. Only certified contractors can sell it — and only after the manufacturer's own inspector signs off.
