Commercial Roofing Contractor Serving Wisconsin

Metalmaster Roofmaster is a commercial roofing and architectural sheet metal contractor based in McHenry, IL, minutes from the Wisconsin border, and we build across Wisconsin. For 49 years we have delivered roof installation, reroofing, maintenance, and metal fabrication for general contractors, building owners, facility managers, and institutional and public bidders. If your Wisconsin project needs union crews, self-performed work, and real fabrication capacity behind it, our shop and crews are a short drive north.
