Ice and Watershield

ICE & WATER SHIELD is a self-adhered roofing underlayment and is a 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 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.
Product Description.

​​Seals around fasteners — The rubberized asphalt layer in ICE & WATER SHIELD membrane seals around fasteners, resisting leakage caused by water back-up behind ice dams, or from wind driven rain.

Superior Adhesion to the Deck — The self-adhesive membrane bonds firmly to the roof deck without need for heat or special adhesives.

Watertight Laps — Membrane easily forms water-tight overlaps without special treatment.

Protects under all standard sloped roof coverings — ICE & WATER SHIELD roofing underlayment protects under slate, tile, cedar shakes or metal, as well as under conventional asphalt shingles.

Slip resistant surface — ICE & WATER SHIELD self-adhered membrane has a slip resistant embossed surface to maximize traction and safety for applicators.

Reroofable — Unlike granular surfaced membranes, ICE & WATER SHIELD smooth surface underlayment will not adhere to the underside of the exposed roof covering. ICE & WATER SHIELD membrane can be applied over the old GCP self-adhered underlayment in retrofit applications, making re-roofing easier, less costly (since there is no need to remove the existing underlayment), more durable and environmentally friendly (as the structural deck remains intact avoiding the need to purchase additional wood decking).

​​Membrane will not crack, dry out or rot — ICE & WATER SHIELD® roofing underlayment resists attacks from fungus and bacteria; maintains its integrity for long lasting protection.
