Why Timberline® AS II ?
Timberline® AS II SBS Modified IR Shingles combine all the beauty of Timberline® Shingles with UL 2218 Class 4 impact resistance. Their beauty is unlike any other, thanks to our proprietary shadow bands. 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. When you compare Timberline® AS II SBS Modified IR 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.
