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.
This detail is used where the copper cap flashing should not be visible on the building facade. The cap flashing, therefore, does not fully cover the coping. The roof side of the coping is detailed similar to Detail 9.3D.
