"The Ultimate Choice For A Rugged Wood Shake Look"
<< Back to Shingle Styles & Colors
For Homeowners
- Sophisticated Design...
Carefully sculpted shingle tabs combined with a subtle “shadow effect” result in a sophisticated yet rugged design
- Incredible Appearance...
Grand Canyon’s massive, extra-thick shingle tabs are up to 20% thicker, to give your roof the unmatched dimensionality and depth of real wood shakes
- Super-Heavyweight “Plus” Construction...
At over 400 lbs. per square, compare Grand Canyon shingles to any of the so-called “heavyweight” shingles on the market!
- Natural Color Palette...
Specially-formulated color palette is designed to accentuate Grand Canyon’s natural wood shake look
- High Performance...
Custom-specified, ultra-high performance Micro Weave® core provides better protection layer for layer
- Safer...
Class A fire listing from Underwriters Laboratories—the highest rating possible—and safer than wood shakes!
- Stays In Place...
Dura Grip® adhesive seals each shingle tightly and reduces the risk of shingle blow-off. Shingles now warranted to withstand winds up to 130 mph!1
The Ultimate Peace Of Mind...
Lifetime ltd. warranty with Smart Choice® Protection for the first ten years (non-prorated material and installation labor)2
- Perfect Finishing Touch...
For the best look, use Timbertex® Distinctive Ridge Cap shingles. (In the West, use high profile Ridglass® Ridge Cap shingles, or Sequoia®/Canyon™ Ridge Cap shingles are also a good choice.)
