Ice dams form when warm air leaks from the attic and melts snow on the roof edge. In Minneapolis homes with poor insulation, this happens fast once winter temperatures drop below freezing. We run self-regulating heat cable along the eaves and valleys to keep water moving. Old houses in the North Loop and Northeast often have this issue because the original roof decks lack enough ventilation.
Cheap crews sometimes skip the drip edge or use constant-wattage cable that overheats and fails within two seasons. We follow Hennepin electrical permit rules and pull them before any line voltage work starts. The cable we use is rated for 5 watts per foot and ties into existing GFCI outlets so it shuts off when not needed.
Most calls come from Uptown and Powderhorn after a big snow followed by a warm spell. We check the attic for missing baffles and add insulation where heat is escaping. This stops the melt-refreeze cycle that pushes water under shingles and into the living space.
Call 24/7 if water is already coming through the ceiling. We can get temporary heat cable up the same day in most cases and schedule the full permanent run during normal hours Mon-Sat 7am-7pm from our shop at 3433 NE Broadway St.
