How a WindProven™ Limited Warranty

Can Benefit Property Owners!

Gleason Roofing LLC and GAF make a great team providing our customers with an Industry-first wind-proven limited warranty 

What Does the WindProven™ Limited Wind Warranty Entail?

As a result of years of innovation and testing, GAF has the confidence to offer an industry-first wind-proven limited warranty with no maximum wind speed limitation on Timberline® Shingles with LayerLock® Technology when the shingles are installed with the required combination of four qualifying GAF accessory products.1

The patented LayerLock® Technology on Timberline® Shingles mechanically fastens together the two layers of a Timberline® Shingle during manufacturing for strength. In addition, the StrikeZone® nailing area (which is the widest in the industry) is covered with microgranules that allow the GAF Dura Grip™ sealant to create a strong asphalt-to-asphalt bond. Because of their unique construction, only four nails are typically required to secure these shingles, unless otherwise required by local codes. The system is completed by installing the required combination of four qualifying accessories—GAF Starter Strips, Roof Deck Protection, Ridge Cap Shingles, and Leak Barrier or Attic Ventilation.1

Is There a Cost for This Protection?

When installed with the required combination of four qualifying GAF accessory products, Timberline® Shingles with LayerLock® Technology qualify for coverage under the WindProven™ Limited Wind Warranty1 (this coverage applies to the shingles only and not the whole system). The warranty cannot be purchased.

How to Submit a Warranty Claim

Should a homeowner experience an issue with blown-off shingles, The homeowner can start the process online and monitor the claim’s status. Once a claim is opened, the owner will be notified about additional information required to process it—such as photos, installation documentation, and shingle samples. If you find yourself in this situation, your customer may call you for assistance or repairs. Keep in mind that the homeowner has nine months to gather the information required for claim processing. If repairs are needed before the claim is fully processed—because of leaks, for example—be sure to provide notice to GAF and preserve evidence of the original damage to support the claim under the warranty.

Helping Property Owners Reduce Risk

People living in hurricane-prone or other windy areas can benefit from the industry’s first limited wind warranty with no maximum wind speed limitation.1

Installing Timberline® Shingles with LayerLock® Technology and the required combination of four qualifying GAF accessory products, their LayerLock®-labeled Timberline® Shingles qualify for the WindProven Limited Wind Warranty.1 Your customers will know that they are protected, no matter how fast the wind blows.

Wind isn’t just an issue for hurricane-prone areas, of course. It can be a major component of spring and summer storms, which are often accompanied by wind-driven rain. So, no matter where you work, it’s important to educate your customers and offer the protection they need.
