WindProven™ Limited Wind Warranty¹

• Code Compliance:  Meets the prescriptive solar reflectance and thermal emittance requirements according to the 2016 Title 24 Standards and is rated by the Cool Roof Rating Council. Find out more about Title 24 here.
• Beautiful Look:  Feature GAF proprietary color blends and enhanced shadow effect for a genuine wood-shake look.
• High Performance:  Designed with Advanced Protection^® Shingle Technology, which reduces the use of natural resources while providing excellent protection for your home.
• 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.¹
• 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.²
• Stays in Place: Our legendary Dura Grip™ sealant pairs with the smooth microgranule surface of the StrikeZone^® nailing area for fast tack. Then, an asphalt-to asphalt monolithic bond cures for durability, strength, and exceptional wind uplift performance.
• Highest Roofing Fire Rating:  UL Class A, listed to ANSI/UL 790.
• Peace Of Mind:  Lifetime limited transferable warranty with Smart Choice^® Protection (non-prorated material and installation labor coverage) for the first ten years.³ A cool roof from GAF helps minimize solar heat gain by reflecting incoming sun rays and re-emitting the absorbed energy — thereby reducing the heat going into the house and in the attic. This may translate into savings on air-conditioning bills.⁴
