"Wrap-on" roof & gutter de-icing cables.

This pre-assembled cable has been designed for the sole purpose of preventing the formation of ice dams on pitched roofs with non-combustible tab shingles and in metal or plastic gutters and downspouts. It provides drainage channels so that as natural thawing occurs, water has a path to flow off the roof and through the gutters and downspouts. This cable is not for use on a flat roof nor is it intended to clear the roof of snow and ice.
