What you can expect
Ontario Certified Roofing works on roofs for homeowners across Newmarket, from our shop at 18580 Dufferin St. Rather than push a fixed service menu, we start from your specific roof: tell us what’s going on and we follow up with what we can do.
Homeowners who have reviewed our work describe Adam and his team as transparent, professional and diligent — showing up on time, working hard, and cleaning up before they leave. When we find something unexpected, like rot or poor insulation under an old roof, we tell you honestly so you can decide what to do next.
Why homeowners choose us
Grounded in what’s verified today — nothing more.
Adam and his team are one of those hard working professionals I've met. They were tasked to repair my deck after a fire repair and from start to finish, were transparent, professional and diligent. Unfortunately the weather wasn't ideal and that didn't stop them.
We honestly couldn't have asked for a better experience with Adam and his team. From day one, they were friendly, professional, and really easy to deal with. The crew showed up on time, worked hard every single day, and made sure everything was cleaned up before they left.
I couldn't be happier with the work done by OCR. Adam and his team went above and beyond what I expected. Originally, they were just going to replace the shingles, but during the job, they discovered leaks in the old roof, rotting plywood, and very little insulation.
