Watch me install a neater, more reliable alternative to electric rooftop de-icing cables in the video below.  When a roof gets warm enough in winter to melt rooftop snow, the resulting water runs down the roof and re-freezes along the cold, unheated edges. This can cause water leaks and a buildup of ice. Click below to watch my installation of a virtually invisible heating system that melts rooftop ice without visible cables.
