Winroc has expanded from 1 store to 34 branches across Canada plus 9 branches in the United States. We grew our business, and still operate, using a customized regional approach to meeting our customers' needs. Each Winroc branch supplies wall and ceiling products selected to meet local building standards and withstand the local climate. Just as importantly, the people in Winroc's branches make the decisions, so you get local-distributor service with national distributor selection and buying power.
