We Protect what matters most

GAF Timberline HDZ Shingle Guide

It's never just a roof. It's a promise, kept.

Providing a home means making a promise — of shelter, security, and stability. It says to the people who count on you, “You’re going to be safe, dry, and warm under this roof.”
Choosing a Timberline HDZ® roof is a great way to help keep that promise.
It’s our first shingle ever to come with patented LayerLock™ Technology. That means it’s engineered for the best possible installation.
