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.

Je viens de faire l'achat d'une maison de ville en rangée. L'inspecteur en bâtiment a indiqué dans son rapport que l'isolation du grenier est déficiente. Il y a présentement entre 6 et 8 pouces d'isolation. Il s'agit d'isolant en fibre de verre et de polyuréthane giclé. Également un conduit et un évent de plomberie ne sont pas isolés. Pourriez-vous me faire une soumission pour ramener l'isolation à du R50. Merci!
