Application of the Resisto Duolap system for flat roofing is one of the many professional roofing services offered by Stewart Roofing Ltd. under our Stewart Flat Roofing banner. Proper application of top-quality Resisto waterproofing products is one of the best ways to protect yourself and waterproof your property from the ravages of the often extreme seasonal weather that’s become common in the greater Ottawa area.

Stewart Flat Roofing is a Certified Resisto Duolap Installer. We are one of the few flat roofing companies in the area to have earned the designation. What does that mean for you when you hire us to install your flat roof? For starters it means we can offer you a safe installation without an open flame propane torch of a bitumen-based elastomeric waterproofing system and access to a 20 year warranty from the manufacturer.  Only Certified Resisto Duolap Installers are able to offer this to their clients. It means our team of professional roofers have gone through the training required to meet Resisto’s standards for installation. It’s the roofing profession’s equivalent to “earning your stripes,” and it means our customers get the benefit of that incredible flat roof warranty.

At Stewart Flat Roofing, we only install quality products from manufacturers we believe in. Our reputation is on the line every time we climb up on a roof, and so it’s important for us to believe in the products we sell our customers. We are confident that Resisto is one such company. Their Duolap CAP GR is a high-performance SBS modified bitumen cap sheet membrane that offers incredible waterproofing and durability. It’s clean, fast and easy to install and provides incredible reliability and a superior warranty.
