The new Glenwood offering marks what GAF calls the industry’s thickest triple-layer asphalt shingle. With it’s thickness and staggered exposure, Glenwood shingles’ triple-layer construction provides maximum dimensionality for an authentic wood-shake look at a fraction of the cost of traditional wood shakes. The shingles also carry a Class A fire rating, which wood shakes can’t offer, and StainGuard protection helps prevent blue-green algae from discoloring the roof. DuraGrip Adhesive seals each shingle tightly, reducing the risk of blow-off. Glenwood Shingles feature a lifetime limited transferrable warranty with SmartChoice Protection allowing for non-prorated material and installation labor coverage for the first 10 years. Pricing will vary.
