Are Owens Corning shingles good quality?

Yes, Owens Corning shingles are considered good quality and are one of the top three shingle brands in North America alongside GAF and CertainTeed, with a strong reputation among contractors. Owens Corning Duration series, which is the flagship architectural shingle, is considered good quality because it features SureNail Technology, a woven fabric strip in the nailing area that provides excellent fastening strength and 130 mph wind warranty, TruDefinition color with vibrant granule blends for attractive curb appeal, and StreakGuard algae protection with 25-year warranty that uses copper and zinc granules to prevent blue-green algae streaking. Owens Corning shingles use fiberglass mat construction that resists tearing and provides good fire resistance. They are manufactured with good granule adhesion to prevent premature granule loss. Warranty is strong with lifetime limited warranty defined as 50 years for original owner and 10-year algae warranty. Owens Corning has a large network of Preferred and Platinum Preferred contractors who can offer extended warranties. Price is competitive at 100 to 150 dollars per square for materials. While GAF has larger market share, Owens Corning is often praised for SureNail Technology that improves installation accuracy. For most homeowners, Owens Corning Duration is a very good quality shingle offering excellent balance of appearance, durability, wind resistance, and value.
