A-1 Roofing Co.

We provide commercial roofing installation, maintenance and repair services throughout the greater Chicago area. Since 1910, our family-owned company has served businesses, public entities, architects, general contractors, building owners, developers and management companies. We help customers design roofing systems by considering building use, installation requirements, environmental impact and long-term maintenance costs. Our team works with a broad range of commercial roofing systems rather than promoting a single solution. We also offer roof-maintenance software and a long-term inspection and repair program to help customers manage their roofing investments.
