LayerLock™ Technology

Only from GAF

New LayerLock™ Technology powers the industry's widest nailing zone and the first wind warranty with no maximum wind speed limitation.

Engineered For the Best Possible Installation

Take a peek inside: see a CT Scan of an actual shingle to see how LayerLock™ Technology fuses the common bond.

Enhanced Common Bond

Proprietary technology mechanically fuses the common bond between overlapping shingle layers.

DuraGrip™

Our legendary DuraGrip™ sealant pairs with the smooth microgranule surface of the StrikeZone™ nailing area for fast tack.

Accuracy

Up to 99% nailing accuracy

The StrikeZone™ nailing area is so easy to hit that a roofer placed 999 out of 1,000 nails correctly in our tests.**

Up to 600% larger nailing area

LayerLock™ Technology mechanically fuses the common bond between overlapping shingle layers. The added strength at the common bond powers the StrikeZone™ — the industry's widest nailing area.† 

Clear Nailing Target

Nails can be placed anywhere in the StrikeZone™ Nailing Area — on or between the lines! 
Note: the first course of shingles installed should always be nailed on the lower nail zone line.‡

Speed

Up to 30% faster nail fastening

Thanks to the industry's largest nail zone.**

Time Motion Study

In an independent research study, Timberline® HDZ™ Shingles were fastened to the roof deck with 30% faster nail fastening* vs. our standard architectural shingles**

Secondary Fastening

All nails placed within the StrikeZone™ Nailing Area penetrate the shingle below for secondary fastening.

Alignment Guide

The top paint line of the StrikeZone™ Nailing Area acts as a visual indicator for faster shingle alignment with the previous course; the top line lines up with the top of the shingle below.

Windproven™

No Max Wind Speed Limitation

When installed with the required combination of GAF Accessories, Shingles with LayerLock™ Technology are eligible for an industry first: a wind warranty with no maximum wind speed limitation!*

No Max Wind Speed Limitation

Then, an asphalt-to-asphalt monolithic bond cures for durability, strength, and exceptional wind uplift performance.

Fast Tack

Our legendary Dura Grip™ sealant pairs with the smooth microgranule surface of the StrikeZone™ Nailing Area for fast tack.
