      • 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

      115-year WindProven™ limited wind warranty on Timberline HDZ® Shingles requires the use of GAF starter strips, roof deck protection, ridge cap shingles, and leak barrier or attic ventilation. See GAF Roofing System Limited Warranty for complete coverage and restrictions. Visit gaf.com/LRS for qualifying GAF products.

      2Results based on a study conducted by Home Innovation Research Labs, an independent research lab, comparing the installation of Timberline HD® Shingles to Timberline HDZ® Shingles on a 16-square roof deck using standard 4-nail nailing pattern under controlled laboratory conditions. Actual results may vary.

      3See GAF Shingle & Accessory Limited Warranty for complete coverage and restrictions. The word “Lifetime” refers to the length of coverage provided by the GAF Shingle & Accessory Limited Warranty and means as long as the original individual owner(s) of a single-family detached residence [or the second owner(s) in certain circumstances] owns the property where the shingles are installed. For owners/structures not meeting the above criteria, Lifetime coverage is not applicable.

      4Potential for savings depends on various factors including, but not limited to, radiative properties of shingles installed, climate zone, utility rates, location, and HVAC equipment efficiency. For the radiative properties of each shingle in this brochure, visit the CRRC’s Rated Products Directory at coolroofs.org/products.
