Flat Roof Overlays

Commercial Flat Roof Company of Chicago has specialized in the construction and maintenance of commercial and industrial flat roofs for over 30 years in the metropolitan Chicago area. Our unmatched expertise has allowed us to find solutions for every flat roof condition, including highly innovative and cost effective flat roof overlays, a unique process where our technicians lay a fresh layer of membrane over the top of your building's existing roof to add additional protection from leaks and harsh conditions.

Our Process

Our expert technicians begin each overlay project with a complementary inspection of the condition of your building's current flat roof. Our expert technicians will assess the stability the roof, looking for blistering and other signs of wear and tear from years of weather conditions and other damage. 

If we determine that a flat roof overlay is the best solution for your building, we will begin construction by identifying and removing any blistered or otherwise damaged areas of the roof. Once the blistered and damaged areas of the roof have been properly sealed, we will add a new layer of TPO or modified bitumen over the existing layer of roof, and seal it again with a leak free membrane.

All of our work is backed by our signature 100% Leak Free Guarantee, giving you peace of mind that your building's flat roof overlay will withstand up to 30 years of weather and other debris. If you own a commercial or industrial building in the Chicago area and believe your building could benefit from a flat roof overlay, repair, restoration or replacement, contact us today!
