Most homeowners don't think about all the components that make up the roof of their home, but there's a lot going on underneath your shingles. The shingles are the outermost layer of your roof and they help protect you from the sun's rays, rain, snow, and wind. Digging deeper, there's another layer of protection between the roof deck and the shingles: underlayment, which plays a vital role in helping protect your home from moisture damage.

The revolutionary LayerLock™ technology, patented by GAF, has changed the game for both roofing contractors and homeowners, making Timberline HDZ® shingles easy and fast to install and providing the industry's first unlimited wind speed warranty.
