ABSTRACT:
A gutter for a building includes a longitudinal body having a central concave channel, a front edge and a rear edge. The concave channel defines inner and outer surfaces. A curled retaining flange is formed along the front edge and defines inner and outer surfaces. A transition portion is formed at the intersection of the concave channel and the retaining flange. Tangents of the outer surfaces of the concave channel and the retaining flange originating at the transition portion form an acute angle. If desired, a roof flange can be formed along the rear edge of the longitudinal body.
