Abstract: Disclosed is a device for protecting a roof gutter so that the gutter will remain clean for the free flow of rain water therethrough. The device is a lid in the form of a curb overlying the rim of the gutter along the length thereof. The curb has a raised, porous edge rising above the rim of the gutter and forming a wall for catching and holding debris, while allowing rain water to pass therethrough. Special advantages are obtained when the device additionally includes a strip or toe section which is contiguous with the curb section and overlies that portion of the roof which is adjacent to the gutter. Both the curb section and the toe section of the device are advantageously porous throughout, being made from a meshed fabric.
