HOTVALLEY PHOTOS: SHINGLED ROOF
As you can see in this photo, HotValley is performing and created a melt path for snow melt water in this roof valley where ice problems would be problematic. As a result, snow melt water can freely flow down to the roof edge and ice problems in the roof valley are eliminated.
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.
