ABSTRACT:
A non-clogging eaves trough comprising an elongated sheet formed with a flange attachable to the roof of a building. The sheet includes a continuous smoothly curved portion extending outwardly, downwardly and then inwardly of the flange, and an upwardly open trough carried by and below the curved portion. The curved portion overhangs the trough, and a generally vertical screen extends between the trough and the curved portion and engages the latter at the sharp angle beneath the outermost reach of the curved portion so as to avoid diverting water from the smoothly curved portion.
