The Problem With Zig-Zag Heat Cables

Ice Cables

Traditional “Zig-Zag” heat cables are not designed to clear your entire roof edge: rather, they merely melt away ice and snow in the area immediately surrounding the cables. Here are some of the problems inherent in these heat cables’ design:

 

  • At best, any heating cable, either self-regulating or constant wattage, works only moderately well when there is a very modest amount of snow accumulation.
  • In areas where structures have 12″ of snow or more accumulated on rooftops for a large portion of the winter, or where annual snowfall exceeds 75″, zig-zag cables are rendered practically useless:
  • Tunnels will form in the snow pack resulting in the reformation of ice dams between, on top of and all around the cables’ “zig-zag pattern”. With anything more than a moderate amount of snow, the cables simply can’t do anything to help.
  • Zig-zag cables are unsightly during warm weather months: a constant reminder even on warm sunny days that winter will be back again!
