Grace Ice & Water Shield Underlayment

The most severe weather is no match for Grace self-adhered underlayment

Roofing contractors and builders stake their reputations on quality workmanship. A roofer's workmanship is only as good as the product being installed. That's why we trust Grace Ice & Water Shield's roofing underlayment to protect homes in the most extreme climates around the world, and architects choose our products because they meet the most demanding design requirements.

All Grace self-adhering underlayment's outperform other brands because they:

• Seal aggressively to roof decks to create a watertight bond and prevent water migration

• Seal tightly around roof fasteners to prevent leaks

• Seal to form watertight bonds at vulnerable overlaps for superior water-shedding

Additionally, RIPCORD® Split Release On-Demand technology makes it easier to protect vulnerable details like chimneys, valleys, and roof-to-wall transitions.
