WeatherLock Self-Sealing Ice & 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® Roofing offers WeatherLock™ Self-Sealing Ice & Water Barrier Products and are designed for both new construction and re-roofing 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 build-up 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.

What Causes Ice Dams?

An ice dam is a ridge of ice that forms at the edge of a roof and prevents melting snow from draining off the roof. The water that backs up behind the dam can leak into a home and cause damage to walls, ceilings, insulation and other parts of the house.
