Jansen Roofing & Repair Inc. – Ice Protection for Eaves and Valleys
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’s adhesive bottom surface is protected with a disposable silicone coated release film, which is split down the middle for simple and cost-effective application. The “Peal & Flop” method is especially effective in valleys and other difficult places using manageable lengths. Even more important, WinterGuard can be repositioned before deck adhesion occurs.
