GRACE ICE & WATER SHIELD® protects a homeowner’s roof from the damaging effects of water intrusion due to wind-driven rain and ice dams because it:
- Fully adhered roofing underlayment sticks aggressively to deck surface
- Forms a watertight seal around fasteners used to install shingles and other roof coverings
- Forms watertight seal at overlaps
- Protects all standard sloped roofs–slate, tile, shakes or metal, as well as ordinary asphalt shingles
