They came out the next morning, found a few soft spots and repaired everything the same visit. Price was very reasonable and they showed me photos of the work before and after. Good flat roof repair is hard to find in this city so I am keeping their number saved.

Clean install, no leaks, and it actually looks way better than the old one. The team was friendly, showed up when they said they would, and cleaned everything up after. Great choice for skylight replacement on flat roofs in Toronto. Fair price too would happily recommend them to anyone

 Trustindex verifies that the original source of the review is Google. Had some issues with my flat roof after that last storm, so I called Flat Roofs Toronto for a repair. They came out quickly, explained what was wrong, and fixed it the same day. Super friendly crew and very reasonable pricing. It's hard to find a good flat roof repair company in Toronto, so I'm glad I found these guys. Would definitely use them again.

They were straightforward about the cost, came out on schedule and completed the replacement in about six hours. The new skylight is clean, well sealed and the installation quality is clearly better than what was there before

 Trustindex verifies that the original source of the review is Google. Had a flat roof skylight repair done after another roofing contractor's patch job failed. They were upfront about what had gone wrong with the previous repair and what the proper fix would be. Got it done right this time and the skylight has been leak free for eight months now

 Trustindex verifies that the original source of the review is Google. Flat roof skylight replacement was exactly what we needed. Professional throughout, priced the job fairly and completed the installation cleanly and on schedule. New skylight looks great and the waterproofing around it is properly done. Been through a tough Toronto winter without any issues
