Mountain Ridge is a self-sealing shingle of three-piece construction and thickness of five layers that combines durability with flexibility and good looks, for use in capping hips, ridges, or rakes of shingled roofs. Mountain Ridge high-profile hip and ridge accessory is the perfect finishing touch for your roof with blended color and high-profile design. The difference is noticeable...by blending in. Mountain Ridge meets the hip and ridge accessory requirements for the CertainTeed Integrity Roof System which is comprised of underlayments, shingles, accessory products and ventilation all working together. Blended color creates a unified look with the field shingles, instead of a "striped" look. Rounded edges give a substantial, finished look. The Integrity Roof System is designed to provide optimum performance-no matter how bad the weather conditions are.
