When you’re protecting a home, it pays to start with the original. GRACE VYCOR™ ICE & WATER SHIELD® from CertainTeed is the premier self-adhered roofing underlayment—delivering unmatched leak protection for sloped roofs of all kinds. With over 45 years of best-in-class performance history, it’s no wonder professional contractors trust this underlayment to safeguard their work and their reputation.
Watertight Performance
GRACE VYCOR™ ICE & WATER SHIELD® provides roof protection where it matters most. Its advanced rubberized asphalt layer creates a watertight bond right to the roof deck—wrapping snugly around nails and fasteners. That means added peace of mind at critical spots like valleys, vents, and edges, where leaks are most likely. The result? Long-lasting protection against water intrusion caused by ice dams and wind-driven rain.
Easy to Install. Hard to Outperform.
Engineered for straightforward installation and robust protection, GRACE VYCOR™ ICE & WATER SHIELD® underlayment stands up to the toughest roofing challenges.
- Foldless release liner for smoother, more efficient application.
- RIPCORD® split-release feature simplifies installation in valleys, around chimneys, and along roof-to-wall transitions.
- Forms watertight laps with no special treatments or additional steps.
- Suitable for use with shingles, slate, tile, cedar, and standing seam metal roofing.
Innovation and Integrity
CertainTeed’s commitment to sustainable building practices adds even more value to our best-in-class underlayment. In 2023, we acquired RenuCore recycling technology, allowing us to transform reclaimed shingle scrap into water-resistant pellets used in hot mix asphalt—keeping materials out of landfills and extending their life in the built environment.
