The most severe weather is no match for our self-adhered underlayments

Roofing contractors and builders stake their reputations on quality workmanship. That's why they trust our roofing underlayments 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 of our self-adhering underlayments 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.

We sweat the details to make roofing faster, easier and more profitable for contractors and owners

We advanced roofing technology in 1978 by introducing the first self-adhering roofing underlayment product. Our R&D team innovates continuously to improve installation efficiency and ensure our products are the most durable and resilient.

  • GRACE ICE & WATER SHIELD® is the original self-adhered underlayment that delivers superior waterproofing performance and has been installed on more than two million homes, including many in the most severe climates.

  • GRACE ULTRA™ is a unique self-adhered underlayment formulated with a butyl adhesive that delivers unmatched thermal stability. It is suitable for use under copper, COR-TEN® steel and zinc roof coverings.

  • GRACE ICE & WATER SHIELD® HT is a version of the flagship product that is formulated to be more thermally stable and ideal for use under metal roofing or in high-temperature roofing assemblies.

  • GRACE SELECT® is a code-compliant performance alternative to granular underlayments. It’s lower thickness makes it lighter and easier to apply than heavy granular surfaced materials.
