Abstract: An elongate continuous soffit panel having an adjustable width comprises a first member having a soffit portion including a proximal periphery and a generally parallel and spaced apart distal periphery extending along a lengthwise dimension of the soffit panel, and having a fascia portion coextensive with the soffit portion along the distal periphery and extending generally upwardly therefrom for fastening the soffit panel to roof fascia of a building. The continuous soffit panel also comprises a second member connected to the first member and having a flange portion extending generally at an angle from the soffit portion of the first member for fastening the soffit panel to a side of a building, the second member being adjustably connected to the first member so that the width of the soffit panel is adjustable responsive to variations in distance between the side of the building and the roof fascia.
