Asphalt Roofing

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 JW Roofing and a GAF Timberline HDZ® roof is a great way to help keep that promise. It’s the first shingle ever to come with patented LayerLock™ Technology. That means it’s engineered for the best possible installation.

A GAF Timberline HDZ® roof is so much more than shingles. It’s layers of protection, working together to help keep your home safe from rain, snow, sun, and wind. In fact, installing 4 qualifying GAF Accessories — GAF starter strips, roof deck protection, ridge cap shingles, and either leak barrier or attic ventilation — in one roof system makes Timberline HDZ® Shingles eligible for the

WindProven™ limited wind warranty. Timberline HDZ® Shingles also feature GAF Time-Release Algae-Fighting Technology, for long-lasting algae-fighting power, and come with a 25-year StainGuard Plus™ Algae Protection Limited Warranty against blue-green algae discoloration.

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

KEY BENEFITS:

• 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.

• Up to 99.9% nailing accuracy — The StrikeZone™ nailing area is so easy to hit that a roofer placed 999 out of 1,000 nails correctly in our test. Up to 30% faster nail fastening thanks to the industry's largest nail zone.

• Dura Grip™ sealant pairs with the smooth micro-granule surface of the StrikeZone™ nailing area for fast tack. Then, an asphalt-to asphalt monolithic bond cures for durability, strength, and exceptional wind uplift performance.

• WindProven™ Limited Wind Warranty— When installed with the required combination of GAF Accessories, Timberline HDZ® Shingles are eligible for an industry first: a wind warranty with no maximum wind speed limitation.

• 25-year StainGuard Plus™ Algae Protection Limited Warranty against blue-green algae discoloration. Proprietary GAF Time-Release Algae-Fighting Technology helps protect shingles from unsightly stains.
