Recent reviews frequently mention fast response for leaks and urgent downspout issues. Homeowners note straightforward assessments, fair pricing, and steady communication throughout the job. Several reviews describe timely completion and follow-up visits to check attic areas or drainage after the work. Customers also appreciate willingness to handle smaller repair calls.

We had an excellent experience with this roofing company. They truly went above and beyond their scope of work.

Despite their busy schedule, they managed to fit us in on short notice to replace our leaking roof. Throughout the entire process, their team kept us informed and completed the installation on time with no issues.

Colin, the owner, also provided several after-service visits. He inspected the attic, checked that the eavestroughs were functioning properly, and offered professional advice on attic insulation. He even helped review an insulation quote with us to make sure we understood what was needed to fix water condensation in the attic — completely outside his normal scope of work.

Colin and his team are genuine, professional, and kind people. It’s rare to find a company that cares this much. We highly recommend them to anyone looking for reliable roofing work.

I wish I could give 7 stars.

Had a two-story downspout fall off during the snow, creating a major ice hazard for my tenants' walkway. I called Colin and he was incredibly responsive. His team came out quickly, gave me an honest assessment, and secured everything properly. Professional, fair pricing, and great communication. Highly recommend for any eavestrough repairs in Oshawa!

I recently connected with Colin to do some work on a building with a major leak on its flat roof. I found that his urgency for the building owner to get a repair done in a timely manner was rare in this business, which is someone who cares about the customer. I can't say enough good things about him as I feel he's an honest person to go along with his business too. I would highly recommend him for your roofing needs!

I had a leak around my exaust fan on my roof. Went to a roofing depot to buy matching shingles but I only need 2, I would have to buy a whole bundle 70$ appox. The lovely lady behind the counter asked all the contractors in the room if they had a couple to give me. Without hesitation Colin stepped up ,exchanged #'s with me as he did not have his work truck. He also gave me some tips on what he would do to ensure I fix it right ! Next day I received 3 shingles from Colin !
I don't know about you, but this is the kind of person I would hire to keep my family and investment safe !!!

I can’t say enough good things about Colin and his team. As a new homeowner, I was having a hard time finding a roofing company willing to take on a smaller repair job—most places simply weren’t interested. But Colin was different. He didn’t discriminate based on the size of the job and went out of his way to help me out.

His communication was clear and timely, and the work was done with care and professionalism. It’s rare to find someone so reliable and willing to help, especially when you're new to homeownership. I truly appreciate his dedication and would absolutely hire him again in the future. Highly recommended!
