GRACE Ice & Water Shield Underlayment Review

GRACE Ice & Water Shield Underlayment

GRACE ICE & WATER SHIELD® self-adhered roofing underlayment is a premier membrane composed of two waterproofing materials—an aggressive rubberized asphalt adhesive backed by a layer of slip resistant coated high density cross laminated polyethylene film. The rubberized asphalt surface is backed with a foldless release paper that protects its adhesive quality. During application, the release paper is easily removed, allowing the rubberized asphalt to bond tightly to the roof deck. The Ripcord® embedded in the adhesive provides the applicator a “split release on demand” feature.

  • Provides best in class roof leak protection
  • Ripcord® split release makes it easier to waterproof detail areas
  • Provides long lasting adhesion to roof deck without primers or fasteners
  • Forms superior, high quality laps
  • Rubberized asphalt seals around roof fasteners
  • 108 square foot roll

GRACE ICE & WATER SHIELD® is a versatile underlayment material that may be used on sloped roofs, under mechanically attached roof coverings such as asphalt shingles, slate, tile, cedar, and standing seam metal in many climate and assembly conditions.

GRACE ICE & WATER SHIELD® is supplied in 3 ft wide rolls of varying lengths. Membrane strips are also available in 75 ft (22.9 m) long rolls at widths of 6 in. (150 mm), 9 in. (225 mm), 12 in. (300 mm) and 18 in. (450 mm).

    Best underlayment I’ve come across. Most of my work is based in Massachusetts where winters can be rough and lots of ice damming happens and it does wonders keeping the water out. Cons would be the paper on the back is one piece and the rip cord can be annoying to get out. And if the temperature is above 80 there is no second chances once the papers peeled.

    + PROS: Works great, seals nails nails when applied at high temps
    - CONS: Paper backing can be a pain, pricey

    Grace is our go to Ice & Water, Metal or asphalt with our weather in Illinois & Iowa. As an installer first, I noticed it very easy to work with and walk on. The cost is certainly worth the product

    I prefer to use a granulated ice and water shield. Grace is a pain in the butt to install.

    + PROS: It does the same job as granulated
    - CONS: It's doesn't have the easy to remove Plastic film... they use brown paper and it is a pain to install.
