Cope trim, also known as drip cap molding, is a type of molding used to protect the edges of a roof from water damage. It is typically made of metal or plastic and is installed along the eaves and rakes of a roof.
Cope trim is important because it helps to prevent water from seeping into the roof and causing damage to the structure of the house. It also helps to improve the appearance of a roof and can add value to a home.
