A building fascia is disclosed, which comprises an elongate gutter and a soffit. Being made from sheet aluminum, steel, or copper, the gutter has back, bottom, and front walls and a channel extending along and into the gutter from the back or bottom wall, preferably from the back wall. Being made therefrom or from vinyl or other polymeric material, the soffit has an edge portion inserted into the channel. Lips formed on the edge portion and on one of two side walls of the channel have sufficient flexibility and are shaped to permit the edge portion to be readily inserted with a snap action but to restrain the edge portion against being withdrawn from the panel. Preferably, one of the side walls of the channel is spaced narrowly from the bottom wall of the gutter, the narrowly spaced walls flaring into the gutter so that ice forming between the narrowly spaced walls is extruded into the gutter. The gutter has a rib extending along an upper edge of the front wall, a ledge sloping downwardly and backwardly from a lower edge of the rib, and a flange extending and sloping downwardly and frontwardly from a lower edge of the ledge. The building fascia further comprises a mounting bracket extending across the gutter, between the upper edge of the front wall and an upper edge of the back wall. A front portion of the mounting bracket is shaped as a hook and is hooked over the flange. |
