  I waited 2 years to post this. I recently had my flat roof replaced by Best Flat Roof in June 2024, and I cannot recommend them enough. My 1986 home had been struggling with years of "lay-over" jobs where previous contractors buried old gravel under new tar. This trapped moisture and eventually rotted out 13 sheets of my plywood decking. I had already upgraded my drainage to dual 4x3 downspouts to try and help, but because the old roof was sagging and "dished," the water couldn't even reach the gutters. The crew from Best Flat Roof finally solved the puzzle. They performed a total tear down in June 2024, stripping everything to the bones. The timing was perfect. Just weeks after they finished, Toronto hit that record-breaking July 2024 rainstorm that flooded the DVP. For the first time, I saw my 4x3 downspouts actually "pouring" and doing the job I installed them for. The roof has since survived two of the most erratic winters we’ve seen—from deep freezes to the wild temperature swings of 2026—with zero issues. What they did right: Total Strip-Down: They didn't just cover the mess; they removed every bit of the old "gravel sandwich" to fix the hidden rot. Engineered Slope: The tapered insulation finally fixed my drainage flow. Professional Integration: They properly tied the new Soprema system into my existing 4x3 drainage and angled the gutters steeply to ensure high-velocity flow. Durability: Battle-tested through record floods and multiple freeze-thaw cycles. If you have an older flat roof in the GTA and want it done right the first time, call these guys. They don't just patch; they rebuild it better than the original.

  I recently had a flat roof completed with Dennis and the team. This was a challenging project as the roof in bad shape and there was a deck on top of it. Dennis and the team came in and did an amazing job. I did a thorough evaluation of 10 companies and they beat them out. If you have a flat roof give them a call.

  Oleg came out to our house to give us an estimate on fixing a leak from our flat roof. He identified that the problem was the flashing and window casing rather than the roof. He saved us unnecessary roof work and countless dollars. Best Flat Roof is a trustworthy company!
