Discover the difference that Berkshire Shingles can make on your home. These laminated shingles have a large 8-3/8" x 8-1/2" tab and feature unique shadow lines behind the tabs that add to the look of dimension.

Significant wind can cause shingles to blow off the roof deck. Missing shingles can lead to leaks and other interior damage. The quality and performance of the sealant on a shingle helps plays an important part in wind resistance performance. Owens Corning certifies our shingles to industry recognized wind resistance standards through independent third-party testing laboratories. To see the wind resistance warranty on this product, refer to the TECHNICAL SPECIFICATIONS tab.
Algae growth may cause brown to black streaks on roofs but this discoloration does not impact the service life of the shingles. Algae species are transported through the air and growth occurs to varying degrees in all regions of the country; especially those subjected to warm, humid conditions. Algae should not be mistaken for fungus growth, soot, dirt, or moss. Almost all types of roofing systems are susceptible to algae discoloration. Where noted on the individual Product Detail page Technical Specifications tab, Owens Corning provides limited warranty coverage on some of our shingles for algae resistance. For full details of coverage, refer to the actual warranty for details, limitations, and requirements.
