Job Stories From Montréal, QC
Ice damming on a roof in Montréal, Qc

Henri owns a beautiful house in Montréal. He is living there since 1986 and plans to stay for another couple of years. For a while, Henri noticed during winter that his house had ice damming on the roof. Then, wondering what would be the problem, he called Systèmes Sous-sol Québec for a free inspection and estimate. 

Our sales representative made a free inspection of the house. The client's problem was the attic. The attic was not well insulated and had a lot of air leaks. So when the hot air enters the attic due to air leaks and bad insulation, it warms up the roof and causes snow melting and then creates ice damming on the roof. Then water infiltration in the attic will certainly happen quickly. 

Our production team went to our customer's house to fix his attic. First, they removed the old fibreglass insulation. Mold was even found in the fibreglass. Then, once removed, they sealed all holes that were provoking air leaks. Holes that were found were wiring holes, around the pipes and air duct. Once all holes were sealed, they install our cellulose insulation on the entire attic ground. 

Our cellulose insulation gives the best results for a perfect insulated attic. It is effective, quick to install, safe and environmentally friendly.

After the job was done, the customer quickly saw the difference. His home was warmer during winter and no more ice damming were on the roof.

Not enough cellulose insulation in attic.Need to add more
Vicinity of Boul. Saint-Germain in Montréal
We have icicles as well as ice dams in front. We only heat the house to 71 degrees Fahrenheit or about 21 degrees Celsius. We have a fan in the attic to cool it. The bathroom fan is vented into the attic..
Vicinity of Pasteur in Montréal
Ice damn (and long icicles) on the back of the roof over a foot thick. Ice damn along the front of the house a little less thick. Some ice along the side also. Our roof and eaves were completely re-done in 2009. We had the insulation of our small attic crawlspace done in 2010, but I doubt if it was done properly. I assume that the problem is improper insulation in the crawlspace. I would like an estimate of the work to correct the situation. I assume this will be done in the Spring?

We leave in a 800sq ft flat roof row house in Montréal. We have noticed condensation on our clings this winter and recognize the previous owner who did renovations did a poor job with insulation. We are hoping to redo our roof but would like to get it insulated at the same time. Do you offer that service and how much would a job like that cost approximately?
