GAF is the largest roofing manufacturer in North America, and their Timberline shingle line is the best-selling residential roofing product in the country. Western Building Center stocks GAF shingles, underlayment, ventilation, and roofing accessories at all 11 Montana and Idaho locations.
Montana roofs face severe conditions — heavy snow loads, freeze-thaw cycling, high winds, and hail. GAF Timberline HDZ shingles are designed for these conditions with a wind rating up to 130 mph, a Class A fire rating, and GAF’s LayerLock nailing zone for fast, accurate installation. The lifetime limited warranty covers manufacturing defects, and GAF’s WindProven limited wind warranty is available when installed with specific GAF accessories.
Our roofing team provides material takeoffs from your plans, competitive contractor pricing, and boom truck delivery that places shingle bundles directly on your roof. Whether you’re re-roofing a starter home in Ronan or building a custom home in Whitefish, WBC and GAF have your roof covered.
