This location is a very high snowload region of the Rocky Mountains.
Historically, snowpack/ice would build behind the dormer and significant
damage would result during freeze and thaw cycles to the back side of the
dormer. To prevent repeat performances, the HotSeam system was installed.
As seen in this photo, it is possible to eliminate 100% of snow/ice build-up
in problematic regions on any roof structure.
As shown in this photo, HotSeam was installed to prevent 100% of the
snow/ice problems that would historically develop on this problematic roof
edge. HotSeam is simple to install on existing standing seams and the heat
trace cable is simple to inspect, maintain, and replace. With HotSeam, melt
back is not limited.
