Commercial roofing contractors from around the country were honored as projects of the year for 2019 in four categories: low slope; steep slope; sustainability and waterproofing. The competition highlights both quality workmanship and noteworthy features in design, system application and roof installation. More than 40 projects were nominated, and the top three winners in each category were honored during a special ceremony at the Miller Lite Club inside AT&T Stadium, the home of the Dallas Cowboys and one of Sika Sarnafil’s signature roofing projects.
