The CertainTeed Integrity Roof System®

A superior roof is stronger than the sum of its parts. A quality roofing system involves the underlayments, shingles, accessory products, and ventilation all working together. Day after day, year after year. At CertainTeed, we call that the Integrity Roof System®. The Integrity Roof System is designed to provide optimum performance -- no matter how bad the weather conditions are.
