LayerLock™ Technology

Only From GAF

The 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.

*15-year WindProven™ limited wind warranty on Timberline® Shingles with LayerLock™ Technology requires the use of GAF starter strips, roof deck protection, ridge cap shingles, and leak barrier or attic ventilation. See GAF Roofing System Limited Warranty for complete coverage and restrictions. Visit gaf.com/LRS for qualifying GAF products.

Remember the last time this happened on one of your roofs? Yeah, we couldn’t either and GAF is on millions of rooftops so I think we would have heard something about this rather peculiar phenomenon. So why do some shingle manufacturers make such a fuss about nails, nail placement and reinforcement tapes while completely ignoring the critical role that sealant plays in wind performance? Well, instead of a benchtop sales demo we went to this highly regarded hurricane research facility to show you it’s not all about the nails. Dura Grip™: available on all GAF Shingles, including our new Timberline® HDZ™ Shingles. Learn more at gaf.com/layerlock
