Flat Roof Repair in Chicago, IL

Flat Roofing Materials and Installation Built to Last

Chicago flat roofs require more than standard materials and basic installation practices. Proper flat roofing performance depends on selecting the right system and installing it with precision to resist ponding water, leaks, and thermal movement. Nombach works closely with property owners to choose materials that match the building’s needs while complying with Chicago roofing regulations.

Our modified bitumen roofing systems offer longer life expectancies than many traditional flat roof options and are virtually maintenance free. In addition to using top-rated materials, we’ve refined installation methods not commonly practiced by other flat roofing contractors. Our proprietary flashing techniques, including the Nombach Perma-Flash Wall System, help prevent water intrusion at critical transition points and extend the lifespan of the roofing system.

Proven methods like these have stood the test of time, delivering years of trouble-free performance and affordable flat roof repair for Chicago property owners.

Extend the life of your roof at a much lower cost than you may expect.

Hot Asphalt Roofing

Many Chicago-area property owners prefer a more traditional approach when choosing a roofing system for residential or commercial buildings. Built-up hot asphalt roofing has been used for more than a century and remains a trusted solution for flat roofs that require redundancy and durability.

Every project, big or small, is completed to our professional standard of excellence for consistent quality and complete customer satisfaction.
