One of our clients, Waterville TG, has relied on our expertise for several years to maintain and re-roof its Waterville (420,000 square feet) and Coaticook (250,000 square feet) plants.

"We have chosen to focus on Soprema products for our roofs, which are precisely what the team at Gagné et Roy Inc. uses. They were also within our price parameters when we launched the bid. We also appreciate the expertise and rapid response of the team at Gagné et Roy Inc. This kind of work is not always performed in the easiest conditions – you can’t be afraid to get dirty! - But these guys always deliver. They are people of experience on whom we can rely. "

- Bruno Rosa, Plant Engineering Project Engineer at Waterville TG
