Product Use:
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:
G.A.P. 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.
