After it snows, a cycle of melting and refreezing can occur. Heat escapes from the attic and warms the underside of the roof, which causes some of the snow to melt. The sun can also cause snow on the roof to melt. Water runs down along the roof to the eaves, which extend beyond the edge of the house. Since the eaves are not heated, the water can refreeze. This freezing can cause an ice dam to form. The gutters can fill with ice and cause them to back up, which can make it impossible for water to drain into the gutters and downspouts.
The weight of the ice in the gutters can cause them to sag. If the problem is not corrected, the weight can eventually cause the gutters to fall off the house. Water can also leak under the shingles and into the inside of the house, where leaks can cause damage to the ceiling, insulation, and interior of the building. This can cause thousands of dollars worth of damage to a home.
Gutter heaters from Ice Arrest can melt snow on your roof so that it can flow into the gutters, eliminating ice dams. This is an effective solution that can prevent ice dams from forming and spare you from a host of problems.
An ice dam is a serious problem that can cause major damage to your home. Be prepared to prevent ice dams this winter by installing gutter heaters on your roof to melt snow and allow it to flow easily into your gutters and away from your house.
