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.

Waterproofing shingle underlayment prevents leaks from wind-driven rain and ice dams.

Water-resistant layer over the roof deck and a secondary barrier against leaks.

Perfect starts every time and designed to work in tandem with the roof shingles above.

Choose the best, covered by the strongest warranty in the business.

Perfect finish for hip and ridge lines, complementing all CertainTeed shingles.

Engineered for ideal roof ventilation especially when matched with CertainTeed Intake Vents.
