Protection for vulnerable areas…

WinterGuard™ waterproofing shingle underlayment is the solution for winning the battle against water penetration in your roof's most vulnerable places. WinterGuard is a composite material of asphalt polymers, formed into a rolled sheet. The asphalt makes it vapor-tight, and the polymers make the asphalt elastic and sticky. This protective barrier is able to stretch and seal around nails driven through it. Placing WinterGuard a minimum of 24" past the interior wall line at the eave provides your first line of defense.

WinterGuard is one of the key components in the CertainTeed Integrity Roof System™ which is comprised of underlayments, shingles, accessory products and ventilation all working together. The Integrity Roof System is designed to provide optimum performance--no matter how bad the weather conditions are.

MetaLayment™
    Underlayments

MetaLayment™

When it comes to applying a metal, shingle, slate or mechanically-fastened tile roof, you need an underlayment that will increase the protection of your investment.  Fulfill that need with CertainTeed's MetaLayment.  Clogged gutters, high winds and ice dams cause water to accumulate on lower sloped roofs which can cause damage.  MetaLayment can combat these elements.  It is waterproof, does not rip and seals around nails driven through it.
DiamondDeck™
  30 Years Underlayments

High Performance Synthetic Underlayment

CertainTeed’s DiamondDeck™ High Performance Synthetic Underlayment is manufactured to provide best-in-class performance in terms of both weather protection and contractor safety.


DiamondDeck is a synthetic, scrim-reinforced, water-resistant underlayment that can be used beneath shingle, shake, metal or slate roofing. It has exceptional dimensional stability compared to standard felt underlayment.

 
Felt underlayment can wrinkle when it becomes wet and “telegraph” those wrinkles through to the shingles applied over it. DiamondDeck eliminates this problem and its special top surface treatment provides excellent slip resistance, even when wet.

  • Excellent 6-month UV stability – Finish roof when you are ready
