Here HotShingle2X was installed on this metal shingle roof in a high snow load region. It is important to know that HotShingle2X can be installed on any new construction or new roof project regardless of the roofing material. As you can see in this photo, heat trace cable raceways are strategically separated from each other for maximum melting capacity. In fact, any 2X HotEdge design relying on two heat trace cables offers a minimum of 20 inch melt back from roof edge. We are able to accomplish this with two heat trace cables because our designs rely on direct heat transfer and are separated to achieve optimal melt transfer up from the roof edge.
