“I’m passionate about Stewart Roofing Ltd., and for good reason.”

Stan Stewart, Owner

Roofing isn’t simply about laying down shingles…

…it’s also about treating customers with respect and earning their business while earning their trust.


It’s about quality roofing products with credible warranties – names like Owens Corning and CertainTeed. It’s about professional installation and roofing expertise that focuses on ensuring sound advice, structural integrity, certified energy efficiency and lasting aesthetic appeal. Any “fly-by-night” roofer can sell you and install a pack of shingles. Stewart Roofing Ltd delivers a complete customer service experience from the moment you decide to contract one of the best roofing companies in Ottawa.

I started working in the roofing trade at age 15, carrying bundles of shingles up a ladder while learning the trade inside and out. My mentors were old-school tradesmen and journeymen roofers with an unwavering work ethic who taught me the importance of quality craftsmanship and the self-satisfaction of a job well done.

At Stewart Roofing Ltd I’m surrounded by a group of dedicated people who share the belief that we are here to provide that level of craftsmanship and service to our customers every day. That includes our office staff, our estimations team, and one of Ottawa’s best roofing installation crews. From the moment you decide to become a customer, you receive five-star treatment from all our staff through every phase and aspect of your roof installation.

We don’t give you a reason to second-guess!

Stewart Roofing Ltd. is very proud to have been named Homestar’s ‘Eastern Ontario Contractor Of The Year’ five times in the past six years

We’ve earned an A+ rating with the Better Business Bureau and have earned Owens Corning’s Preferred Contractor status as well as CertainTeed’s highest standard Select ShingleMaster 5 Star certification. We’ve also earned the trust of hundreds of customers who choose to go on-line and share their positive customer experience with us. Given our long history as an Ottawa roofing contractor we are now seeing second generation customers who have decided once again to put their trust in Stewart Roofing Ltd to install their residential or commercial roof. As a business owner, I can’t express any greater appreciation for the customers who keep coming back.

Now that you’ve landed on our website I invite you to look around to see the roofing and insulation services we provide and the top-quality products we use. Shingled roofing, flat roofing, metal roofing and insulation. We have it all and have for more than 30 years. It’s the reason Stewart Roofing Ltd continues to be the one of the best roofing companies in Ottawa.


From the very moment that you meet a member of the Stewart Roofing estimation team, you gain access to an informed resource.

Our knowledge of the profession means we can answer all your questions about roofing installation, new technologies and roofing systems and the differences in shingle qualities and material composition. We can help educate you on all the choices available – from top quality asphalt shingles and metal roofing shingles to a variety of industry leading cold flat roofing applications systems – so you can make an informed decision that suits your needs and your budget. Whether you need a complete asphalt shingle replacement, metal shingle installation or flat roof installation, we don’t begin working until you’re satisfied with your choices.


Where you’ll truly appreciate your decision in hiring Stewart Roofing Ltd., is when the roofing installation begins!

Our experienced team of professional roofers has been together for years; the efficiency with which they execute their roofing installation is a thing of beauty to watch. They are meticulous with every detail in the work they do to ensure your roof is installed to the exacting standards of our company and the suppliers who have named us as preferred contractors for their products. I am proud to work alongside this group of highly motivated individuals and confident that they will always deliver the best possible roofing installation in Ottawa.

The roofing industry is full of companies that attempt to reduce their operating costs cutting corners and by hiring unskilled labourers; these individuals are not always the most reliable workers.  At Stewart Roofing Ltd, our roofing installation experts are united in their belief that a zero-tolerance policy for anything that can endanger workers on a roof is the best policy for safety. We abide by that policy every day.


We look forward to roofing you.
