Ice dams can form dangerous icicles and cause water ingress into buildings. The ice dams form because melting snow and ice on a roof freeze when they reach the cold roof edge. The ice forms a barrier and melted water accumulates behind this ice dam. Pooled water behind the dam may leak into the building, causing water damage, or climb over the ice-filled gutter, forming icicles.
Our roof & gutter de-icing systems offer a better way to help prevent ice dams and icicles. With its self-regulating heating cable, the systems provide a continuous drain path for melted ice and snow from the roof through the gutter and downspout. Versatile, reliable, energy-saving, and cost-effective, these systems are the effective answer for roof and gutter de-icing applications.
A few additional issues to watch:
Heat tape should not be used over the thermal insulation or near flammable materials.
Check heat tapes at least once a year, paying particular attention to older tape which may develop cracks in the insulation.
