10 years ago we had our flat roof replaced by this company. Today, after the heavy rainfall in Toronto we had a leak with water dripping from the ceiling. I called Ilia in late morning, and he showed up within a couple of hours , inspected the roof, diagnosed the problem correctly, as a leak from a vent.
I cannot say enough about his responsiveness. I continue to recommend Toronto Star Roofing for any work required on your roof.
