Abstract: A gutter cover is adapted for covering an opening of a generally U-shaped eaves gutter used for catching and distributing rainwater runoff from a pitched roof. The gutter cover includes an elongated cover panel having a longitudinal upstream section adapted for residing proximate a top rear edge of the gutter adjacent an eaves of the roof, and a longitudinal downstream section located away from the roof eaves. The downstream section is adapted for engaging an outwardly-spaced leading edge of the gutter. The cover panel defines a first row of longitudinally-spaced debris filter openings adapted for receiving rainwater runoff from the roof into the gutter. A longitudinal weir ridge is formed downstream of the first row of debris filter openings, and is adapted for slowing and flattening a downstream flow of rainwater runoff bypassing the first row of debris filter openings. The cover panel further defines a second row of longitudinally-spaced debris filter openings downstream of the weir ridge.
