Owens Corning is investing in the longevity of a roof’s curb appeal as it transitions shingle lines and all hip and ridge shingles to a 25-year Algae Resistance Limited Warranty (up from 10 years).
Covering most Owens Corning laminate shingles, including Oakridge® Series, Duration® Series, Berkshire®, Woodcrest®, and Woodmore®, the warranty uses a system approach that pairs proprietary shingle technology with hip and ridge components to help protect homes’ roofs against stains and streaks caused by blue-green algae for up to 25 years. To get the most protection (and this enhanced warranty), approved Owens Corning hip and ridge shingles will need to be installed alongside a new algae resistant laminate shingle roof.
