Savings in energy costs are not assured, and the extent of potential savings can fluctuate depending on factors like the climate region, utility expenses, roofing materials’ radiative properties, insulation levels, HVAC equipment efficiency, and various other considerations.
The Timberline HDZ® RS shingles meet the 2022 Title 24, Part 6 Cool Roof Standards set by the California Code of Regulations and have received a rating from the Cool Roof Rating Council (CRRC).

Qualifying for the Windproven™ Limited Wind Warranty2 involves no maximum wind speed limit, given that it’s installed alongside the necessary combination of four approved GAF accessory products.

This can be employed to meet the Cool Roof Requirements of the California Code of Regulations, specifically in accordance with the 2019 Title 24, Part 6 guidelines.

Unprecedented and vibrant color combinations that haven’t been observed in a cool roof context.
The WindProven™ limited wind warranty, spanning 215 years and applicable to GAF Shingles featuring LayerLock™ Technology, mandates the utilization of GAF Starter Strips, Roof Deck Protection, Ridge Cap Shingles, as well as Leak Barrier or Attic Ventilation. To access comprehensive coverage and limitations, refer to the GAF Roofing System Limited Warranty. To view qualifying GAF products, visit gaf.com/LRS. For installations that do not qualify for the WindProven limited wind warranty, consult the GAF Shingle & Accessory Limited Warranty for complete coverage and restrictions.
Actual energy savings are not assured and the extent of savings can differ based on factors such as climate region, utility costs, roofing product properties, insulation quality, HVAC system efficiency, and other variables.

LayerLock® technology enables the most extensive nailing area in the industry, allowing for swift and precise nailing. The StrikeZone® nailing region is incredibly user-friendly, to the extent that during our test, a roofer accurately positioned 999 out of 1,000 nails.5

When GAF shingles equipped with LayerLock® technology are set up using the specified combination of four eligible GAF accessories, they become eligible for the WindProven™ Limited Wind Warranty, which does not impose any upper limit on the maximum wind speed.4
Findings derived from a study conducted by Home Innovation Research Labs, an autonomous research laboratory, which compared the installation of Timberline HD® Shingles with Timberline HDZ® Shingles on a 16-square roof deck. The comparison involved a standard 4-nail nailing pattern and took place in controlled laboratory settings. It’s important to note that real-world outcomes might differ.
