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 purpose of fascia flashing is to support the shingle edge and to provide a drip edge to prevent water from running back underneath the roofing shingles and down along the fascia and soffit. Preformed eaves flashing/drip edge should be installed under the starter course of the shingle roofing.
