D.M. Henderson Roofing Ltd. has been in operation since 1963. Incorporated by Mike Henderson, it was purchased in 1974 by its current ownership. In its 40-year history, the company has grown from a small, residentially-focused firm into one of the largest full-service roofing contracting firms in Western Canada. In that time, it has developed a reputation of excellence, safety, and performance which is well respected in its industry. The company has performed difficult and challenging projects across the Northwest region of Canada, working in the Arctic, as far north as Pond Inlet, Nunavut and the Yukon, to the northwest coast of British Columbia and its Queen Charlotte Islands, and east into Saskatchewan. Its industrial division has completed major projects in mining, energy service, pulp and paper, and oil extraction sectors.
