America’s #1-Selling Roof Shingle
Discover Why Timberline HDZ Is America’s Best Shingle

WindProven™ Infinite Wind Speed Protection
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.

StainGuard Plus™ Algae Protection
Timberline HDZ® Shingles come with a 25-year StainGuard Plus™ Algae Protection Limited Warranty1 against blue-green algae discoloration, and proprietary time-release technology that releases algae-fighting copper steadily, over time, for long-lasting algae fighting power.

LayerLock™ Technology
LayerLock™ technology mechanically fuses the common bond between overlapping shingle layers. When paired with Dura Grip sealant, an asphalt-to-asphalt monolithic bond cures for durability, strength, and exceptional wind uplift performance.

Dura Grip™ Adhesive Technology
Dura Grip™ Adhesive bond helps GAF Shingles pass the industry’s two toughest wind resistance tests. The sun’s heat activates the Dura Grip™ Adhesive, creating a strong bond between the shingle and the layer below it. It also acts as a sealant that helps prevent water penetration between shingles.
Frequently Asked Questions
The word “Lifetime” refers to the length of coverage provided by your GAF warranty and means
as long as you, the original owner(s) [or the second owner(s) if coverage was properly
transferred during the Smart Choice Protection Period], own the property where the shingles
and/or accessories are installed. The Lifetime limited warranty is applicable only to shingles and
accessories installed on a single-family detached residence owned by individuals. For any other
type of owner or building, such as a corporation, governmental entity, religious entity,
condominium or homeowner association, school, apartment building, office building, or multi-
use structure, the length of the warranty is 40 years.
