Introducing our patented LayerLock™ Technology
Powering the industry's largest nailing area
¿Habla español?
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.
The StrikeZone™ nailing area is so easy to hit that a roofer placed 999 out of 1,000 nails correctly in our tests.**
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.‡
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.
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.
