ABSTRACT:
Roof-mounted devices for providing drainage channels through ice dams that may form on a roof under winter conditions are spaced along the margin of the roof, each device comprising an elongated, heat-collecting metal plate which is installed in a transversely upright position between an adjacent pair of shingles. The plate extends longitudinally in a downward direction along the slope of the roof with its lower end portion projecting clear of the roof. Opposed, major vertical surfaces are thus presented by the plate and are black in color to maximize the collection of solar energy thereby causing a drainage channel to form along the surfaces through dams of ice or snow.
