What Our Customers Have To Say…

Stewart Roofing was actually recommended to us, but we did get two other quotes. Their quote
was in the middle and reasonable. Everyone we dealt with was very professional. They told us
what they were going to do and then actually did it timely and pleasantly. The crew was friendly
and knowledgeable and the office staff helpful. Everything went like clockwork and the roof
looks beautiful. I would highly recommend Stewart Roofing.

Stewart Roofing Ltd. is an excellent roofing contractor. This fine company recently replaced the
roof on my house in Old Ottawa South. I was impressed throughout, from the detailed work of
the estimator, to routinely hearing about the scheduling of the work to be done, to the sense of
safety and assiduousness of the work crew present. I’m pleased with the quality of the work,
and the performance of the new roof. This is great work and customer service at its very best.

I was impressed from the start of the process to the end of the job. The estimator took the time
to explain the products and services offered; to dealing with the office (Bonnie) to set up the
appointment;right through to the guys who actually did the work.. My roof was completed on
time and without any issues. I have recommended Stewart to a friend
Donna S-B.
