A roof de-icing cable keeps ice dams from forming. It doesn’t clear a roof of snow or melt a dam that is already there, so it needs to be installed and switched on before the snow comes. Most kits here are 5 W/ft constant-wattage cable for asphalt shingle roofs, with clips and spacers in the box, and cost well under $1.50 a foot. Self-regulating cable costs more but can overlap itself, and some is rated for metal and flat roofs, which most constant-wattage kits are not.
