In colder months, clogged gutters can become frozen and turn into a solid block of heavy ice and debris. This can cause gutters to buckle and pull away from your house. An ice dam is a buildup of ice under the roof edge. The ice eventually creeps up under the shingles and warps them. Further damage can lead to rotting roof rafters and interior leaks. Faulty insulation and or poor attic ventilation is the root cause of ice dams. Certain Gutter Helmet dealers can install a self-regulating heat cable that can mitigate ice dams and frozen gutters. Additionally, Gutter Helmet‘s patented brackets are specifically designed to carry and conceal the heat cable. Ask your local dealer about this special service.
