Why Us?

We understand that choosing a contractor these days can be difficult. As roofing is an unregulated trade in Ontario, anyone with a truck, ladder and access to free online ad posting can claim to be a professional roofer and as a result the residential roofing industry has become saturated with dishonest, fly-by-night companies that lack experience and the proper know-how. This in turn leads to negative experiences, giving the industry a bad name. The Desmarais Roofing team understands what it means to be a true professional. We possess the proper training, knowledge and skills needed to operate efficiently, to provide a quality service and a pleasant, positive experience for our customers. Our goal to meet or exceed our customer’s expectations has been a huge contributing factor to our strong reputation and ongoing success.

Our company meets the City and Provincial Safety Standard, is fully insured and safety certified. We always ensure a safe workplace for our workers by using the necessary training, safety equipment and safe work practices in order to complete the work safely and efficiently. At Desmarais Roofing, safety is number one.
