As Ottawa’s most trusted team of roofing professionals, Stewart Roofing Ltd is the name to turn to when you’re looking for top notch flat roofing installation. We are proud to be certified with Tremco on the installation of their Geoguard System, as well as with Resisto for their Duolap System. Both those designations reflect Stewart Roofing Ltd Ottawa’s reputation for offering the industry’s most comprehensive roofing application and roof recovery solutions.

For commercial, industrial and residential flat roofing, Stewart Flat Roofing professionals offer expert application of Tremco Geoguard, one of the top Fluid Applied Restoration Roofing Membranes available. Fluid Applied Roofing is the process of waterproofing a roof by applying a cold liquid roof coating. The two-step application includes the initial Geoguard Lo Base Coat followed by the Geoguard Finish Coat. Together these two exceptional Tremco products combine to protect and extend the life of a variety of single ply roof membrane systems as well as Modified Bitumen and BUR surfaces. This is the ideal choice for property owners with a functional roof that may be in the early stages of deterioration who are looking for a cost-effective but durable alternative to a total roof replacement. Geoguard is Energy Star qualified and comes with a 10-year manufacturer’s warranty.

Another exceptional flat roofing solution offering by the Stewart Flat Roofing team is the two-ply high performance Duolap Roofing System. This process combines the waterproofing and durability features of an SBS Modified Bitumen Membrane. Duolap offers a 20-year warranty on their roofing system, on the condition that the system is installed by a Certified Installer that meets all warranty requirements related to installation. The Stewart Flat Roofing team are one of the few Certified Installers in the Ottawa Region, which ensures you both a professional installation and a full 20-year warranty. It’s another reason why the choice you make for your roof contractor is equally as important as the type of roofing product you choose for your installation.
