A cover member adapted to be mounted in a conventional gutter on a building structure in covering relation to the open top to the gutter trough provides a forward upwardly-extending lip portion having a curved outward surface adapted to form a dam to water runoff from the building structure to slow the speed of water runoff flowing over the lip portion to cause the overflowing water to follow the curved outward surface of the lip portion into the gutter while causing leaves and like debris to fall gravitationally over the lip portion outwardly of the gutter. In one embodiment, the lip portion is formed as an integral upwardly and rearwardly curled forward edge to the cover member. In a second embodiment, a coil spring rests between the curled lip portion and the front wall of the gutter to act as a filter against debris entering the gutter. In a third embodiment, the lip portion is formed as a circular bead fitted to the forward edge of the cover member, with a spiral groove in the bead serving to direct overflowing water runoff into the gutter. As desired, drain openings may be formed in the cover member adjacent the lip portion to increase the capacity of the cover member for handling water runoff.
