GRACE ICE & WATER SHIELD® roofing underlayment

Premium performance underlay, protecting roofs since 1978

For architects and roofing contractors, roofs are a source of everlasting concern. Seventy percent of all construction litigation is related to leaks, and every leak is a lost opportunity, representing a cost to repair and a corresponding loss of customer trust. Severe weather seems to be the new normal, and the risk of damage from ice dams and wind-driven rain are higher than ever. Underlayments are the last line of defense in a roofing system, and selection of high quality underlay can be the difference between success and failure.


Aggressive protection since 1978

GRACE ICE & WATER SHIELD® has protected the roofs of over 2 million homes, and been installed on marquee projects in 25 countries, since its introduction in 1978. This high performance solution provides superior performance at an excellent value. GRACE ICE & WATER SHIELD® outperforms the competition, letting contractors shine and keeping families safe and dry.


GRACE ICE & WATER SHIELD® doesn’t just perform well in severe weather, it makes life easier for contractors.

Better for homeowners

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 instal shingles and other roof coverings
  • Forms watertight seal at overlaps
  • Protects all standard sloped roofs--slate, tile, wooden shingles or metal, as well as ordinary asphalt shingles

GRACE ICE & WATER SHIELD® is designed to perform for the life of the roof covering.

Better for contractors

The material is also designed to make jobs faster, easier and safer for roofing contractors.

  • Superior waterproofing protection
  • Embossed surface prevents slips and falls
  • Convenient centre-lines, lap-lines and measurement markings

GRACE ICE & WATER SHIELD® lets contractors save time on jobs without compromising on quality or safety.
