Easy-to-Install Roof Shingles

At the 2020 International Roofing Expo, GAF unveiled their Timberline® HDZ™ Shingle—and soon, you’ll see them up on the roof of the TOH TV Cape Ann Project House. Read on to find out how this revolutionary new architectural roofing shingle makes accurate nailing fast and easy.

Think of nailing a shingle like hitting a ball: the larger the ball, the easier it is to hit. That’s why GAF designed their new Timberline® HDZ™ Shingles with the industry’s largest, high-visibility nailing target—accuracy saves time, and it will get your crew off the roof quicker. Let’s take a closer look at how it works.

Anatomy of a Timberline® HDZ™ Shingle

  1. StrikeZone™ Nailing Area: The StrikeZone™ Nailing Area provides an up to 600% larger nailing target¹ for improved accuracy, and up to 30% faster nail fastening.² By nailing in the StrikeZone Nailing Area, nails pass through two courses of shingles for secondary fastening. Fun Fact: The StrikeZone Nailing Area is so easy to hit that a roofer placed 999 out of 1,000 nails correctly in an independent test.*
  2. LayerLock™ Technology: LayerLock™ Technology mechanically fuses the common bond. Dura Grip™ Sealant pairs with the smooth microgranule 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.

A Photo Finish

Ease and speed of installation aside, beauty and ability to uphold the authenticity of the roof’s architectural integrity are just as critical when it comes to roofing, especially at a project like the TOH TV Cape Ann Project House.

With nearly 6,000 square feet of roof to cover, this 1891 Shingle-style home needed a roof that would appear authentic to the home’s original style. The Timberline® HDZ™ Shingles shown here feature proprietary shadow bands that are applied using a sophisticated, computer-controlled “feathering” technique.

When combined with a randomly blended top layer, the result is an authentic wood-shake shingle look with exceptional depth, contrast, and dimension for a striking finish.
