As you can see on this iconic commercial property at 11,200 foot elevation where average annual snowfall averages 310 inches, the HotSeam was installed behind a small dormer. This area was very problematic with ice build-up. In the spring, massive ice build-up would shift causing damage on back side of the dormer(see inset). Now, with HotSeam in place, is it possible to completely eliminate destructive ice build-up. HotValley was used to allow snowmelt to run around the dormer to the roof edge!
Using HotSeam on a standing seam metal roof it is possible to achieve a melt back further than what the HotEdge Rail could accomplish on its own. Here, we are able to achieve a 3 foot melt back using HotSeam. Please note, melt back beyond what the HotEdge Rail can deliver is rarely necessary since most ice dams and all icicles develop on the roof edge!
Many customers are interested in a melt line that would exceed what the HotEdge Rail is able to accomplish from the drip edge. On this project, HotSeam is able to create a melt line 4+ feet up from the drip edge on this standing seam metal roof. Hot Seam is attached to the standing seam using clamps to press heat tape firmly against the metal panel resulting in heat transfer that extends from seam to seam. It is possible to keep an entire problematic area on a standing seam metal roof structure free of snowpack and ice with the HotSeam product.
Before photo: Ice dams and very large icicles always developed on this problematic area on a metal roof at 11,000 feet elevation. Icicles so large they would break off and fall back and break restaurant windows.
After photo: All ice dams and icicles have been eliminated as a result of a HotEdge Roof Ice Prevention System. It is easy to see how HotEdge and HotSeam can work together to eliminate problems.
