New Roof!

I wasn't sure what needed to be done with my father's roof and the most important thing to me was finding someone I could trust. The roofing scene can be tricky to navigate. I've had bad luck in the past. Ontario Downspout Services had been recommended by a neighbour. Harvey answered the phone and he was a calming and thoughtful soul who started the whole...

Mark and his crew did a great job replacing the flat roof on my house and dealing with a leak I had into my living room by replacing a strip of roof and eaves trough along a side of my house in an awkward narrow area between my house and my neighbours. Mark shared photos as they removed the old materials so I could see the problem areas and understand how the...

After comparing a few quotes, I went with Mark and Ontario Downspout. His initial assessment was incredibly thorough and left me confident in my choice. A few weeks later, his crew arrived to tackle the job over the course of a weekend. They did fresh eaves, soffits, and did a great job freshening up the back exterior of my house -- changing old, rotting wood into fresh...

I found Ontario Downspout Service on Homestar and I am so glad I did! I initially got Mark to give me an estimate to replace one of the downspouts on my roof that became detached. He was the only one that gave me a quote right away and came over very quickly to fix it. While on the roof, we got talking and he inspected my roof and gave me an estimate. The work was...
