Metal Gable Roof Flashing is used to trim the edge of the roofing panel at the gable end of the roof. It should match the eave flashing that extends along the drip edge of the roof. Eave flashing can be used in its place if the panel is allowed to hang over the gable end. Butyl tape between the trim and the panel eliminates leaks. The primary function of Metal Gable Roof Flashing is to shed or direct water away from roof edges and penetrations to prevent infiltration into the building.
