North America's largest roofing manufacturer — and a featured brand on Roof Gutter Now roof replacements across Northeast Ohio.
GAF has been manufacturing roofing products for over 130 years and is the largest roofing manufacturer in North America. Their Timberline shingle line is the best-selling shingle brand on the continent, and their products are engineered as complete systems — shingles, underlayment, starter strips, ridge caps, and ventilation designed to work together.
For homeowners, the name matters for one practical reason: warranty strength. When a full GAF system is installed correctly, the manufacturer stands behind it — which means your roof is protected by a company that will still be around decades from now.
Our go-to GAF shingle for full replacements — LayerLock technology, wide nailing zone, and strong wind ratings for Ohio storm seasons.
We pair GAF shingles with matched underlayment, starter, ridge cap, and ventilation so warranty coverage stays intact — no mixed-brand shortcuts.
GAF spec sheets and product documentation slot directly into our insurance claim packages, making scope and pricing easy for adjusters to verify.
From Charcoal to Weathered Wood, we bring GAF sample boards to your estimate so you pick from real shingles, not a screen.
A properly installed GAF system carries manufacturer warranty options that outlast most mortgages.
Wind and impact ratings built for the freeze-thaw, hail, and gust cycles Northeast Ohio actually gets.
A documented brand-name roof system is a selling point when your home hits the market.
A sample of the High Definition color collection — we bring real shingle boards to your estimate so you choose from the actual product, not a screen.
Warranty coverage depends on the system, not just the shingle. Here's what we install together — and why skipping components is how other contractors void warranties.
