Really impressed by the responsiveness and integrity of the team, Martin and Louis-Philip. I had a minor issue on my roof with my chimney top blowing off. They came in for an inspection the next day, and ended up fixing it without charging a fees. Will be happy to contact them again for my roofing needs!

We had a water infiltration issue in our garage and contacted Toiture Kolossus for an inspection. They were responsive, professional, and very thorough in explaining what was causing the problem and what needed to be done to prevent further damage.
They provided a clear inspection report, walked us through the situation with photos and a video, and implemented temporary preventive measures to limit further water infiltration. You can tell they care about doing things properly and helping homeowners understand what’s going on, rather than just rushing through a job.
Even though this was a stressful situation for us, their professionalism and communication gave us peace of mind. I would definitely recommend Toiture Kolossus for inspections, diagnostics, and emergency mitigation work related to roofing and water infiltration issues.

Excellent workers. They removed the old roof and installed new shingles, all in one day, cleaned up perfectly when they were done and took away the old materials in a container. They gave me pictures of their work on the roof, an easy to understand explanation of what they had done and ten years of guarantee. They were punctual, respectful of my property, kind and safe.

We had to do the shingles and flashing of our roof. Every step of the project with Les Toitures Kolossus was done to our complete satisfaction. They were professional, always on time, responsive and friendly. The cost was completely fair too. I had the feeling that they are more passionate about the project than I was and I trusted their judgement and excellent work completely. I have no hesitation in recommending them to anyone.
(Oh! and they took such excellent care in protecting our plants and leaving everything super clean when they were done!)
