ABSTRACT:
Modular roofing panels for removing snow and ice from the edge of a roof are interconnected. A defective panel or one damaged by severe weather can be replaced without incurring extensive wiring difficulty. An electrically operated valve element at the edge of the panels can selectively guide water from the roof either over the gutter thus effectively bypassing it, or into the gutter.
