  • Patent number: 4937986
    Abstract: A gutter protector adapted for mounting on a sloping shingled roof for attachment under the next-to-last row of shingles and extending at an inclination to the roof with perforations for flow of water through the gutter protector directly into the gutter and onto the roof and into the gutter. There are a series of alternating perforated sections and imperforate sections that are relatively inclined to cause change of direction of flow to facilitate flow of water through the perforations and to facilitate lifting and washing of leaves and debris from section to section and off the gutter protector away from the roof. An outer end portion extends upwardly from the gutter to obstruct view of the other sections from ground level.
