Abstract: A removable roof flashing cover system for use on structures which are faced with siding, such as aluminum or vinyl siding. By use of this invention, the space between the terminal edge of the siding and roof line can be compensated for during the initial installation or at a subsequent point in time. This invention is particularly useful in compensating for spaces or gaps which may occur in the roof line as a result of reroofing. The composite assembly consists of a channel, a wall bracket, and a removable face panel. The channel and the wall bracket are secured to a vertical building surface. The removable face panel is secured between the channel and wall bracket. When the system of this invention is utilized, a building which is covered with siding can be easily reflashed during a reroofing operation. It is preferred that the channel be J-shaped.
