This roofing company is the best company in Montreal, the team are fantastic, both Martin, the owner and Guy are very friendly and they do superior job. The most important is the great service after installation, summer or winter I call them, they come right the way to check if I have any issue. My roof was done in 2009 and I called them this year in 2017 because I get condensation at one corner of the skylight, they came, added insulation in some area of the roof and when I asked for the cost, Martin told me it is OK and refused to take any money.
