Patent ID: 7121056

Claim:
A heated roofing system, comprising: a) a plurality of shingles each having an upper edge, a lower edge, two side edges, an upper surface, a lower surface, and a predetermined width and comprising an electrically powered resistive heating element, each of said resistive heating elements having a pair of electrical interconnection leads, each terminating in an electrical connector oriented toward and positioned near to said upper edge of said shingle and structured for interconnecting said resistive heating element to a power supply cable near said upper edge of said shingle, said shingles being structured for installation in an abutted, end-to-end arrangement; and b) an elongated, substantially flat power supply cable having a distal end adapted for connection to an electrical power source and having electrical drop-down leads spaced periodically at a distance substantially equal to said predetermined width of said shingles therealong, said electrical drop-down leads comprising pairs of cable electrical connectors capable of removable electrical interconnection with respective pairs of said electrical connectors of said electrical interconnection leads of said plurality of shingles; whereby electrical power may be applied to each of said resistive heating elements in each of said shingles.
