During the winter, heat escaping from an attic or coming from the sun can cause snow on a roof to melt. The water then runs down to the eaves, which are unheated, and refreezes. This ice can get backed up and clog gutters, forming ice dams. If the problem is not corrected, the weight of the ice can pull down gutters and shingles. Water can leak into the house and cause expensive damage.
One of the most effective ways to prevent ice dams is to install low-wattage gutter heater cables along the lower edge of the roof. The gutter heaters resemble heavy-duty extension cords and are plugged into a standard electrical outlet. Gutter heaters are usually laid in a zig-zag pattern on the roof and run through the gutters and several feet into the downspouts.
Gutter heater cables vary in terms of length. The length of cables needed will depend on how far the cables will need to run from the bottom of the roof line.
Gutter heaters melt snow on the roof so that the water runs down into the gutters and downspouts and away from the house. They can effectively prevent ice dams from forming and protect your roof, ceiling, gutters, and shingles.
Gutter heaters from Ice Arrest have controls that respond to changes in temperature. They will automatically turn on if the temperature gets below 38 degrees Fahrenheit and moisture is present. You won’t have to worry about remembering to turn the cables on and off every day.
It is important to install gutter heaters before snowy weather begins. It is dangerous to install them if there is already a lot of snow and ice on the roof. Fall is the right time to think about installing gutter heaters on your roof to prevent ice dams this winter.
