This photo shows a rarely installed double HotValley. This roof valley is, perhaps, in one of the most extreme commercial locations within the continental United States. Because of severe wind drifting and accelerated snow accumulations, a double wide melt path was needed to adequately handle snow melt water effectively.

In this photo, you can see a large tunnel created by the radiant heat from a HotValley system. Although this location is high snow load and understandably snow fell at such a rapid rate and drifted and the result is a melt path (tunnel) for snow melt water. As you can see, it would be impossible for snow melt water to pool and leak into the structure since there is a clear path down the roof valley.

HotValley was designed to prevent problematic ice build-up in all roof valleys. With a single heat trace cable a sufficient melt path is created and maintained for snow melt water to travel to the roof edge. As you can see in from this photo, this roof valley is a deep large valley. Snow drifting and deep snow accumulations are common at this location. A tunnel representing a melt pathway is maintained for snow melt water in this extreme winter environment.
