Icicles hanging along the eaves of your home may perhaps seem beautiful, but they spell problems. That’s due to the fact the similar circumstances that allow icicles to form—snow-covered roofs and freezing weather—also lead to ice dams: thick ridges of sound ice that establish up along the eaves.

The birth of an ice dam: Warmth from the attic heats almost everything but eaves

Dams can tear off gutters, loosen shingles, and result in drinking water to again up and pour into your dwelling. When that happens, the effects aren’t quite: peeling paint, warped flooring, stained and sagging ceilings. Not to point out soggy insulation in the attic, which loses R-price and gets to be a magnet for mold and mildew.

Birth of an Ice Dam

  1. Warmth collects in the attic and warms the roof, other than at the eaves.
  2. Snow melts on the warm roof and then freezes on the chilly eaves.
  3. Ice accumulates alongside the eaves, forming a dam. Meltwater from the warm roof backs up guiding it, flows below the shingles, and into the home.

Rapidly Fixes

Although a permanent deal with for ice dams commonly requires rising the insulation, sealing, and ventilation in the attic, there are straightforward techniques to diminish the injury right after the dam has shaped.

Hacking away at ice dams with a hammer, chisel, or shovel is lousy for your roofing—and unsafe for you. And throwing salt on them will do a lot more to hurt to your plantings than to the ice. Limited of praying for heat weather, here are two halt-gap actions we suggest:

Blow in chilly air

Get a box supporter into the attic and intention it at the underside of the roof wherever drinking water is actively leaking in. This focused dose of cold air will freeze the water in its tracks. “You can expect to quit the leak in a issue of minutes,” says TOH typical contractor Tom Silva.

Rake it

Pull off snow with a lengthy-dealt with aluminum roof rake (higher than) when you stand properly on the floor. A rake with wheels will not harm the roofing.

Use Calcium Chloride

Fill the leg of discarded pair of pantyhose with a calcium chloride ice melter. Lay the hose on to the roof so it crosses the ice dam and overhangs the gutter. If needed, use a extended-managed backyard garden rake or hoe to press it into posture.

The calcium chloride will finally soften through the snow and ice and generate a channel for drinking water to stream down into the gutters or off the roof.
