Our Story

DWS opened its doors in February of 2000. We began with a small team and crew, and tripled in size by the end of our first year. The company has expanded each year since its inception, and is now one of the best-reputed roofing companies in the Ottawa Valley.

DWS began with a mission to provide superior service to our clients and an undeniably excellent finished product. We have stayed true to this mission for two decades.

Our Work

DWS provides roofing and waterproofing services for commercial, industrial, multi-residential, and institutional buildings. We work with roofs and builds of all sizes.

Our foremen are renowned for their expertise and customer service; our company has built a stellar reputation for our quality and efficiency. We pride ourselves on swift project completions without compromising on quality and safety.

Our Scope

In our 20th year of business, DWS has a number of teams who can provide excellent roofing and waterproofing services throughout Eastern Ontario including Ottawa, Cornwall, Brockville, Perth, Pembroke, Trenton, and Peterborough. We are happy to provide estimates on work farther from home and have provided services from Manitoba all the way to Haiti.
