What our customers say

Finding good trades is tough (as a former Site Supervisor for a custom builder- I know).  I got the name of Desmarais Roofing from a neighbour who recommended them. They arrived when they said they would, took the amount of time they said they would and charged what they said they would.The job they did (including clean-up) was top notch. Really nice guys, fair price too. I would highly recommend them to anyone.

Having dealt with a number of different roofing companies over the years I was very pleasantly surprised at the level of quality on workmanship and the careful attention to detail when replacing the roof on my residence recently. The communication was excellent, the work was completed in time and the site was left very clean. I wish you the best of luck and I would not hesitate to use your services again should they be needed in the future.

I retained the services of Desmarais Roofing in September of 2009. They responded quickly to my initial call and provided a thorough and accurate estimate of the work to be completed. They arranged for timely delivery of the appropriate materials. I found them to be punctual, and adhered to the agreed-upon terms of the contract. They were friendly and very respectful and I hope to do business with Desmarais Roofing in the near future for the second phase of my residential renovation project.

Sometimes we look for big names and we pay too much money in hope to get the best service and best quality, but this rule is not real all the time. I did business with Desmarais Roofing recently and these guys were amazing, highly professional and respectful for the property and for the contract we signed and delivered all that we had agreed on. I got great quality service for a reasonable price, they were very friendly without forgetting that they were there to do business, and they kept everything clean during and after the job was done. I strongly recommend Desmarais Roofing for their reliability, honesty and professionalism.It was a great experience, Thank you Desmarais Roofing for making my house appear nicer than ever.

Desmarais Roofing was referred to me by a friend who has gotten two roofs done by them and could not say enough about their workmanship and professionalism. They did an amazing job on my house which has a roof with many angles and dormers. After an inspection and free estimate, Chris was able to provide me an accurate quote. He was very thorough and went to great lengths to make sure that everything was “done right”. The cleanup was done meticulously, you would not even know they had been there! I have recommended Desmarais Roofing to many neighbours and friends.
