A Base Flashing is located at the joint between a roofing surface and an intersecting vertical surface, such as a wall or a parapet. Base Flashings are typically angles that are used for attaching roofing materials to as well as capping the top to ensure that the base of the roof is secured. It also allows for the expansion and contraction of the roof and wall. We recommend using a metal primer before installing the roofing materials to the base of the base flashings. This will allow the parts to stick and not break away over time. We offer any style base flashing available.
