What are Flashings?

Flashings are thin, waterproof sections of material designed to protect seams in building construction from water intrusion. Flashings are typically used in places where surfaces are joined that are susceptible to leakage. Roof protrusions such as chimneys or vent pipes are common locations for the use of flashings. Walls adjoining roofs, gutters, and window and door frames are also routinely protected with flashings.
