Our Chicago roofing and sheet metal company serves a broad range of businesses and public entities throughout the Chicagoland area, meeting the needs of architects, general contractors, building owners, developers and management companies. We offer a full range of roofing services. We can start by helping you design the roof that is right for your project by taking a range of factors into account — such as long-term maintenance costs, building uses, environmental impact and installation ease. To help you keep your roof in good order, we use helpful software to make maintenance easier. We also provide a cost-saving, long-term maintenance program to help you extend the life of your roof. Unlike some Chicago roofing contractors, we do not just install and promote one type of roofing. Our Chicago roofing contractors are approved applicators of most major roofing systems, including Carlisle, Johns Manville, GAF, Firestone, Soprema, Henry, Performance Roof Systems, Sika Sarnafil and others. A-1 Roofing Co., has been family-owned since its inception in 1910. Three generations later, we continue to provide the same quality product, professional workmanship and personal attention that our grandfather valued.
