BIRCHWOOD Timberline HDZ Algae Resistant Laminated High Definition Shingles (33.33 sq. ft. per Bundle) (21-Pieces)
BIRCHWOOD Timberline HDZ CA$52.96/EAProduct Overview
LayerLock™ Technology — Proprietary technology mechanically fuses the common bond between overlapping shingle layers.
Up to 99.9% nailing accuracy — The StrikeZone™ nailing area is so easy to hit that a roofer placed 999 out of 1,000 nails correctly in our test.
WindProven™ Limited Wind Warranty — When installed with the required combination of GAF Accessories, Timberline® HDZ™ Shingles are eligible for an industry first: a wind warranty with no
maximum wind speed limitation.
Our legendary Dura Grip™ sealant pairs with the smooth microgranule surface of the StrikeZone™ nailing area for fast tack. Then, an asphalt-toasphalt monolithic bond cures for
durability, strength, and exceptional wind uplift performance.
StainGuard® Algae Protection — Helps protect the beauty of your roof against unsightly blue-green algae discoloration.
