The leading self-adhered membrane roofing underlayment offers premium leak protection for sloped roofs to resist water penetration due to water back-up behind ice dams or winddriven rain. Grace Ice &Water Shield also offers leak protection in trouble prone areas like valleys, skylights, protrusions and other flashing areas. Sold by the roll. Size: 225 square feet roll.
For more than 25 years, Grace Ice & Water Shield® has been recognized as the original and leading self-adhered roofing underlayment. Whatever the roof covering composition is, clay, shingle, metal roofing or other, Grace Ice & Water Shield® is your best insurance against ice-packed roofs.
It is applied to the roof deck prior to the application of the finished roof covering, which is most often shingles but can also be tile or metal. The membrane goes under shingles and seals around nails that hold the shingles in place, so water that doesn't drain properly cannot penetrate the roof. It also creates a weather-tight barrier against wind-driven rains that cause shingles to lift and leak. Affordable and easy to install, it provides added peace of mind for many years, even in the most brutal winters.
Grace Ice &Water Shield® is a premier membrane composed of two waterproofing materials—an aggressive rubberized asphalt adhesive backed by a layer of high density cross laminated polyethylene. 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. In addition, embedded in the membrane is a split release on demand feature called Ripcord®.
- Easy to handle and apply—The self-adhesive membrane bonds firmly to the roof deck without heat or special adhesives. Ripcord is a unique, patented feature that makes Grace Ice &Water Shield easier to apply by giving the applicator a split release on demand. Faster application of the membrane in the straightaways, as well as ease of membrane positioning in detailed areas (valleys, around dormers, etc.), are just some of the benefits.
- Foldless release paper—The foldless release paper provides multiple performance enhancements: fewer edge catches, 180° pull-back, ease of membrane cutting (single cuts) and membrane positioning, quicker “one man installs” resulting in an easier, more productive release.
- Seals around nails—The rubberized asphalt layer in Grace Ice &Water Shield seals around roofing nails, resisting leakage caused by water back-up behind ice dams, or from wind-driven rain.
- Dual barrier protection—Rubberized asphalt and polyethylene are combined to form two waterproofing barriers providing maximum protection.
- Membrane will not crack, dry out or rot— Grace Ice &Water Shield resists attacks from fungus and bacteria; maintains its integrity for long lasting protection.
- Protects under all standard sloped roof coverings—Grace Ice &Water Shield protects under slate, tile, cedar shakes or metal, as well as under conventional asphalt shingles.
- Slip resistant surface—Grace Ice & Water Shield has a slip resistant embossed surface to maximize traction and safety for applicators.
- Proven track record—Grace Ice & Water Shield is the name brand in roofing underlayments with a 30-year track record of protecting roofs from ice dams and wind-driven rain.
- Reroofable—Unlike some granular surfaced membranes, Grace Ice & Water Shield will not adhere to the underside of the exposed roof covering. Grace Ice & Water Shield can be applied over the old Grace underlayment (except over Grace Basik®) in retrofit applications, making reroofing easier, less costly (since there is no need for removing the existing underlayment), more durable and environmentally friendly (as the structural deck remains intact avoiding the need to purchase additional wood decking)
