Abstract: An ice dam remediation apparatus comprises a photovoltaic cell panel DC power source (9) directly connected electrically to a low-voltage electrical heat tape or wire cable (8). The heat tape or wire cable (8) is arranged near the eave (6) of a rooftop (2) in an orientation that will create a plurality of runoff channels or tunnels (11) through the ice or snow covering the roof. The channels or tunnels (11) are oriented along the dip of the rooftop, thus permitting water to drain off the edge (6) of the rooftop (2) instead of freezing and contributing to the formation of an ice dam along the edge (6) of the rooftop (2). Preferably, the photovoltaic cell (9) is situated on a sunny roof surface (3), so as to provide maximum power to the heat tape or wire cable (8), which is situated on a shady portion (2) of the roof, where ice dam formation is most likely.
