Abstract: A gutter and hanger arrangement for a building includes a hanger with a flashing section for anchoring to a roof, a fascia section for overlying a portion of a building vertical wall and a hanger flange joined to the fascia section and having elongate corrugations for slidably attaching a gutter thereto. The gutter includes a bottom wall joined to inner and outer side walls and forming a trough therebetween, the juncture of the bottom wall and the inner side wall comprising an abutment surface for engaging the building vertical wall below the flashing section. The inner side wall is spaced laterally from and extends upwardly of the abutment surface and has a corrugated gutter flange extending generally downwardly in spaced relation to the inner side wall and terminating adjacent the abutment surface to form a passage for sliding the hanger flange longitudinally into interengagement with the gutter flange. The corrugations interlock and inhibit upward movement and disengagement of the gutter from the hanger.
