In the roof valley, it creates a pathway for snow melt water to travel down the drain without refreezing
Heat Tape Asphalt Shingled Roof:
HotValley and HotShingleLOK are two types of ice melt systems used on the roof edge of asphalt shingle roofs. Ice dams can form on any type of roof, but HotEdge has created unique ice melt systems that will get rid of ice dams. HotVally and HotShingleLOK use a unique combination of metal flashing along with heat cable to keep snow melt from refreezing on the roof edge. Unlike other heat tape systems that typically have a zig zag pattern, the heat cable warms the metal plate melting the snow in its entirety instead of in patches. HotVally will keep the roof valley clear of snow while HotShingleLok keeps the entire roof edge clear of snow and ice.
