Cap Shingles

Cap shingles are defined as specially manufactured or field-cut shingles installed along the ridge and hip lines of a roof to provide a finished, weatherproof seal at these peak intersections. Factory-made cap shingles such as Owens Corning DecoRidge are typically 9 inches by 33 inches and are designed to match the profile and color of the field shingles. Proper cap shingle installation is critical because ridge and hip lines experience the highest wind loads on a roof.
