New Roof and Roof Repair Ice and Water Barrier Products

Your roofing system must include protection from wind-driven rain. This is accomplished by installing Ice & Water Barrier directly beneath the shingles.
Owens Corning offers WeatherLock® Self-Sealing Ice & Water Barrier Products and Fiberglas Reinforced Felt Underlayment product. All are designed for both new roof and roof repair projects.
We recommend using WeatherLock® Self-Sealing Ice & Water Barrier Products on areas of the roof where water has a tendency to collect or flow, like vents, chimneys and skylights. By preventing water collection, you’ll be better able to prevent ice dams from forming on your roof. Ice dams are ridges of ice that cause water to back up and sit on a roof, instead of properly draining off. This water can work its way under the roof covering and flow into the attic—and cause water damage to a home’s interior.
