Flat roof garage

We are very pleased with the work of J Stewart Roofing. After researching flat roof repair and obtaining quotes from several roofers to fix our leaky 40 yr old flat garage roof, we chose John Stewart's proposal as we were given a clear outline of what the job would entail, details of materials and a cost breakdown. We feel confident we have maximized the life expectancy of our roof by having J Stewart and team completely remove and replace the roof with the latest specialized materials available for flat roof application. We would highly recommend John and team as they stand by their work which was done neatly, on time and on budget!

flat roof replacement

Did an excellent job replacing our garage flat roof. Plus the salesperson Larry was very helpful and explained what needed to be done. The workers were very professional and left everything very tidy when they completed the job. We would certainly recommend this company.

Replacement roof

I discovered a leak in my roof on Labour Day weekend so I contacted a few companies from this website to get an estimate for a replacement roof. 2 of the 5 companies I contacted responded and I got a couple of estimates for a roof replacement. Unfortunately the estimates were about $3000 apart so I had no idea what the work was worth. I called J Stewart Roofing for a third estimate and it came in between the first two (with no leading!). John took the time to answer all my questions about the different shingles and he explained the ventilation requirements for my type of roof (one of the estimates included serious ventilation revisions). I was impressed with his knowledge and his willingness to make sure I had all the information I needed to make a decision. The decision was easy. I had to wait a couple of weeks for the work due to their busy schedule and he had his crew patch the vulnerable area of my roof until they could get to it. When it came time to do my roof, Danny and crew did a great job. They showed up when they said they would, completed the work in two days, and cleaned up the area really well. I love my new roof!

Reroofing of a downtown gable roof

John Stewart and colleagues did a superb job installing a new Energy Star roof on our home. We were keen to have a new roof that would absorb less solar radiation and help with cooling the house in summer. John took us through the various Energy Star (U.S. rated) products available in the Canadian market, and we chose an economical one. He also waterproofed one of the windows on the side of the house. After the installation, a leak developed above the window. he returned himself on a weekend and made the repair -- no charge. You couldn't ask for better service.

Replaced second floor flat roof

J Stewart has done several roofing jobs for me, my family and my neighbours over the years. We've never had a problem with the work, even many years later. I know they are not the cheapest in town but you can rest assured that they will do a proper job and not cut corners.

Roof repair

Early March 2011, I'm 9 1/2 months pregnant and Toronto gets heavy rainfall! Our roof was done 3 years ago, before we bought our house, by a company that is now bankrupt. Initially we had a small leak in our toddlers room, with more rain it turned into a big mess and our son had to relocate. John came very quickly gave us a quote and squeezed our job in before the next deluge. Our flat rolled roof had become unsealed where it meets the drip edge in several significant places. I was so happy to come home and see the work being done on the roof. J. Stewart Roofing is a professional company. What I most appreciated was his communication and non-patronizing approach. He explained what needed to be done and why and addressed all my questions and concerns. Thank you.

Roof replacement

John did a thorough inspection of my roof and gave a reasonable quote. The work was done quickly and well. Afterward, when I had 1 small issue that required follow up, John came back and fixed that issue plus another that wasn't even his responsibility. Very pleased with the job!

Roof repair

We had a leak in our roof last year and chose J. Stewart Roofing after researching a number of companies and deciding that this was the best. We weren't disappointed. John came out, took photos of our roof and patiently explained what the problem was and how he would fix it. The repair job was great, the price fair, and the problem solved.

This week, after the day and a half rain storm, we noticed another leak. (Entirely separate from what was repaired last year.) I called John and he came out had the repair completed in less than 24 hours.

When it finally comes time to replace our roof, we will definitely be going with J. Stewart Roofing.

Thanks for your help!

Roof stripping & replacement, eaves repair

During the hottest days of the summer the J. Stewart crew perfomed admirably. They were polite, professional, and very tidy. The clean up they performed at the end of each day gave great confidence to my neighbours and me. Nothing seemed to be too much to ask. The eaves repair to previously poor work was better than I expected. Through persistence, the maddening leak in the eaves trough was found, repaired and is completely gone. The attached photos show what a an exceptional job has been done. My sincere thanks to John and his crew for such perfectionism.

John is an experienced roofer having started roofing at a very young age he learned the basics of roofing and gradually became proficient in both shingling and then flat roofing. These two very different types of roofs require a different knowledge base and a real understanding of this can only be gained through actual hands-on work, so that one can see exactly how the materials work together and why.

Flat roofs are particularly tricky to do and have become a specialty for J. Stewart Roofing Ltd. (For further details check out the newspaper article from the Toronto Star on this website. It is vital to gain real knowledge of the materials & techniques to not get stuck in just one way of doing things and stop there.

In this way they have gained a greater library of knowledge on which to draw from, enabling them to know what combination of materials best for each unique customer’s job are presented to them.
