GAP WaterGuard Rain & Ice Protection

    Product Use

    It is ideal for low-slope applications (2″ to 4″ per 12″) that demand complete roof coverage and protection, particularly along the eaves; in fact, its application is required by many building codes in cold weather climates (where icing along the eaves is anticipated or where the average January temperature is 25°F or less) or areas of high wind to prevent moisture intrusion caused by ice dams and wind-blown rain.

    Material Performance

    GAP WaterGuard Rain & Ice Protection is manufactured on a woven fiberglass mat with a SBS polymer modified asphalt top coating and surfaced with a sand release agent. The bottom coat is an aggressive asphalt-based adhesive, protected with a factory applied, split-release film that is removed prior to installation.
