Flat Roof Replacement Chicago

Flat roofs are the most common roof type in Chicago on two-flats, three-flats, courtyard buildings, and commercial properties. When a flat roof fails, replacement is almost always more cost-effective than repeated repairs. Our verified contractors specialize in flat roof replacement with all major membrane systems.

A flat roof replacement in Chicago costs $8,000 to $20,000 for most residential buildings, depending on square footage and membrane system chosen. TPO membrane is the current code-preferred system in Chicago. It reflects heat, handles Chicago freeze-thaw cycles well, and typically carries a 15 to 20 year manufacturer warranty. EPDM rubber is common on older buildings and is often used when budget is a priority. Modified bitumen is sometimes chosen for commercial applications or where a torch-applied system is preferred. The replacement process involves removing the old membrane down to the decking, inspecting and replacing any damaged insulation or decking boards, installing new insulation to meet current energy code requirements, and applying the new membrane system. A City of Chicago building permit is required for flat roof replacement. All contractors on our list pull permits as part of the project.
