Timberline ® High Definition ® shingles are unlike any others, thanks to our patented High Definition ® shadow bands (U.S. Patent No. 5,666,776). Each shadow band is applied using a sophisticated, computer-controlled "feathering” technique. When combined with our randomly-blended top layer, it results in a shingle with exceptional depth and dimension—and a striking look unmatched by any other brand. But don’t just take our word for it. See for yourself. When you compare Timberline ® High Definition ® shingles to typical architectural shingles, it’s easy to see why they’ll look sharper and more beautiful on your roof—while enhancing the resale value of your home!
