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.
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 the weather conditions.
Due to variations in computer monitors and printers, the color sample seen on your computer screen may not exactly match the corresponding color. To verify actual product color, ask to see the actual product, available through your CRE Roof Masters roofing contractor near me.
WinterGuard is warranted against manufacturing defects and to remain watertight for the same period as the warranty duration carried by the shingles applied above it -- up to a maximum of 50 years.
