Abstract

If roof top snow melt water is allowed to refreeze on the colder areas of the roof, an ice dam can be formed. A heated drainage path ensures this water is drained away from the structure's foundation. The various sheet metal raceway products disclosed contain spring-like folded members to securely press against the self-regulating heating cable, thereby maximizing the thermal conduction between the heating cable and the sheet metal raceways. The spring-like members of the raceways ensure a tight thermal contact to heating cables of different thicknesses. The spring-like members compensate for metal fatigue to provide a longer useful life of the installed system. The system also allows easy end of life replacement of the heating cable.
