Ridge Cap

A ridge cap is defined as the finished covering installed over the ridge and hip lines of a roof, consisting of specially designed shingles or metal trim that seals the joint where two roof planes meet. Factory-manufactured ridge cap shingles like Owens Corning DecoRidge provide a thicker, more uniform profile than field-cut shingles. Ridge caps are the last component installed during a roof replacement and must be secured with longer nails (minimum 2-inch) to penetrate through the overlapping shingle layers into the decking.
