Timberline HDZ

It’s a shingle that helps your roofer do their best work.

LayerLock™ Technology strengthens the bond between layers of your Timberline® HDZ™ Shingles. To help your roofer give you the best possible installation. And to help you rest easy when the wind is howling outside.

Here’s how it works:

The strength added by LayerLock™ Technology allowed GAF to create the StrikeZone™ nailing area — the industry’s widest nail zone — which offered 99.9% nailing accuracy in our test.

Timberline® LayerLock™ Technology also powers the industry’s first wind warranty with no maximum wind speed limitation. HDZ™ Shingles are eligible for the WindProven™ limited wind warranty when installed with the required combination of four qualifying GAF Accessories.
