Why Most Commercial Roof Jobs Cost You More Than They Should
It’s not the cheapest roofer that burns you. It’s the one who sounds right, then disappears. Missed specs. Delayed timelines. Stakeholder frustration. Leaks within the year.
We built Chouinard Bros. to tackle every size of roofing project with clear scopes, certified crews, and zero surprises.

We had used Chouinard Bros earlier this spring to replace our roof. We had received about 4 quotes from different companies but Chouinard were better price and much more professional. The installation went great, they were quick and even clean up after themselves as if no work was done. We are very happy with their services

I got 3 quotes: 1st: sent a drone to fly over my roof & said they will send a quote. 2nd: sales person shook my hand and said the will send me a quote based on a view from GOOGLE EARTH? 3rd: Chouinard came the first thing the sales person did was GO ON TOP OF MY ROOF take a look explained what he saw and sent me a quote. Chouinard did my roof I have no problems, a no nonsense company very professional & friendly. I have recommended them multiple time already. Thanks Chouinard :)

We contacted Chouinard Bros to repair a leak in our roof and our experience was excellent. We got a very professional support from Kim and Linda who scheduled a visit to check our issue. The repair was completed the same day and they came on time as promised. I highly recommend their services. Fast, Professional and Efficient.

Chouinard Bros replaced our roof two years ago, and we were so impressed with their services that we had them back 2021 summer to replace our eavestroughs. When the team arrived, they stopped the work because the colour was not the right match (When getting the quote, this was called out as a potential), and like with our roof - they were professional, polite, ensured everything was of the highest quality and very clean (which is really important as the alternative is nails everywhere). We enjoyed having them back. Thank you Chouinard!
