Photo Album: Problem with ice dams on the roof of a house in Sainte-Anne-de-Bellevue, Qc

The problem Every winter Mrs. Cherbina had problems with ice dams on the roof of her house. The cause of this problem is the lack of insulation in the attic. It also created mold in the attic. The solution - Eliminate mold, plug air leaks and blow out good a insulation. We removed the old insulation which was fiberglass to seal all air leaks on the attic floor with expanded foam, added baffles in the soffits to ventilate the attic well and then blown a little over 16 '' of our cellulose fiber insulation to achieve an R- 60 value.

The attic was poorly insulated, had mold and the lack of insulation caused ice dams in winter at the end of

Mold in the attic .

Poor insulation and ventilation of the attic will cause the proliferation of mold

Insulate the access hatch to the attic

Very often the access hatch is a plywood board so this represents a very large air leak as it is very thin, it does not insulate this space well. We add an insulating panel on it for better insulation.

Cellulose fibers

With the air leaks sealed, the mold removed, and the access hatch isolated, we blow just over 16 '' of cellulose fiber to properly insulate the attic and achieve an R-60 value.
