The problem
During winter, ice dams and huge icicles formed on the roof of Mrs. Forget's house. A lack of insulation in the attic was the cause of this problem. Even though Mrs. Forget had re-insulated her attic a few years ago, but the same problem had reappeared.
The solution
We removed the fiberglass insulation that was in the attic to seal all air leaks (joints and holes) with expanded foam. Subsequently, we added deflectors to allow better ventilation of the attic. Finally, we blew a little more than 16'' of cellulose fibers to reach an R-60 value.
