United Roofing Inc. is a growing and dynamic industry leader that prides itself on safety, quality, and customer satisfaction. Established in 2007, a small crew of four people completed the day to day residential projects in Calgary. In 2010 the commercial flat roofing division was developed, and after much success, we started the waterproofing division in 2013. Over the years, United Roofing Inc. has grown into a fully integrated building envelope contractor and has covered millions of square feet on our projects. Now with over 250 full-time staff we can complete any commercial or industrial project, and our dedicated teams have the ability to take on projects of any size or scope to handle all of your building envelope needs.
