Products / WeatherWatch Mineral-Surfaced Leak Barrier

WeatherWatch Mineral-Surfaced Leak Barrier is a self-adhering, fiberglass-reinforced leak barrier with a traditional mineral surface for use with asphalt shingle roof systems. It is installed at eaves, rakes, valleys, and around chimneys and skylights to help prevent leaks caused by wind-driven rain, ice dams, and backed-up gutters, self-sealing around fastener penetrations.
