Counter-flashing (or cover flashing, cap flashing) is a term used when there are two parallel pieces of flashing employed together such as on a chimney, where the counter-flashing is built into the chimney and overlaps a replaceable piece of base flashing.
The counter flashing can be made of a wide variety of materials. It can be wood siding, stucco, vinyl or aluminum siding, or other material which forms the outside surface of a wall. In chimneys and along brick walls, the counter flashing is almost always the same metal which is used for the base or step flashing. Two part metal flashing systems are not harmed in any way by the sun's ultra-violet (UV) rays. UV rays can easily defeat caulking, plastic roof cement or most other flashing substitutes. UV radiation can remove the elasticity of these products and make them brittle.
