Very professional

August 2019: Modification of the roof ventilation with the addition of the new roof.
Big caveat:
Each attic has its specific recipe which contains the vapor barrier, insulation and ventilation. If any of these items are changed it can create dramatic problems in a home. We must therefore keep its original recipe to ensure the health of the attic.
If this recipe is changed greatly, the modification can create concerns that will become more and more serious and will become critical for the health of the people in the building.

I had an emergency leak and Mathieu was fast to help and gave me a detailed report with photos. Excellent service and very friendly!!! Highly recommend!!!!
