Ice dam prevention is most effective from inside the attic, where the goal is a roof deck too cold to melt the snow sitting on it.

An ice dam starts with house heat warming the upper slope. Meltwater runs toward the overhang, which hangs out past the wall in the cold, and freezes there into a ridge that traps more water behind it and pushes it under the shingles.

Three Attic Steps For Ice Dam Prevention

Ice dam prevention inside the attic comes down to three steps in a set order. Step one is attic air sealing, which keeps warm air off the roof boards.

Step two adds insulation depth, holding heat in the rooms below. Step three places a baffle at each eave, which lets outdoor air enter at the soffits and sweep under the roof deck. Done together, they keep the entire roof near the outdoor temperature.

Ice Dam Prevention For Caledon Snowfall

Roughly four and a half feet of snow falls on Caledon in an average winter, and the higher ground to the north and west often collects more. Heavy snow on a warm roof is how ice dams grow, so this work pays off in Caledon.

Heating Cables Treat The Symptom

Roof cables and snow raking can keep a channel open, yet neither touches the heat loss behind the ice. Working from the attic fixes the cause and lowers the heating bill as a bonus.

If meltwater has already wet the fill near the eaves, that strip is pulled out and replaced as part of the work.

Ice Dam Prevention Price Range

Ice dam prevention is priced as a bundle of sealing, insulation and baffles. On a 1,200-square-foot attic it typically runs $2,300 to $4,800, depending on the depth already in place.

Attic Insulation Cost

Attic insulation cost comes down to four things: attic floor area, the depth already there, the material chosen and whether old insulation must come out first.
