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.

Consumer Construction recommends the Integrity Roof System for a flawless roofing system that will last for decades.

Step 1:

WinterGuard™ Waterproofing Shingle Underlayment Protection for vulnerable areas – Designed to prevent leaks from wind-driven rain and ice dams. WinterGuard is especially effective on low slopes, flashing areas and in valleys. WinterGuard is required as a valley liner in valleys and at the eaves as ice dam protection.

Step 2:

DiamondDeck Synthetic Underlayment – A secondary barrier against leaks DiamondDeck provides a protective water-resistant layer over your roof deck. It is a synthetic, scrim-reinforced, water-resistant underlayment that has exceptional dimensional stability compared to standard felt underlayment.

Step 3:

Shingles & Accessories – High-quality shingles are available in a wide variety of styles and colors covered by one of the best warranties in the business. Accessories provide the perfect finishing touch while effective ventilation helps guard against premature roof deck deterioration and provides year-round benefits. A properly balanced ventilation system is required.
