WeatherLock® Self-Sealing Barrier
To protect roofs from wind-driven rain, Owens Corning offers WeatherLock® Self-Sealing Ice & Water Barrier Products and our new Fiberglas™ Reinforced Felt Underlayment product. All are designed for both new construction and reroofing projects.
Also use WeatherLock® Self-Sealing Ice & Water Barrier Products on areas of the roof where water has a tendency to collect or flow. These areas include valleys, vents, chimneys and skylights. It’s important to prevent water collection on a roof because that can cause an ice dam to form. This ridge of ice causes 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.
