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.
Flashing is an extremely common practice among mobile home owners looking to protect their homes from water damage. It's used for roofing and is meant to keep water from entering your house. Your roof is usually made up of a waterproof membrane and then shingles on top of that. What flashing does, is fit between the waterproof membrane and shingle, and blocks any holes or gaps that may be present between the two sections.
