Watertight Exteriors installs TPO (thermoplastic polyolefin), EPDM, and other single-ply membrane roofing systems for commercial and industrial buildings throughout Chicago and the suburbs. These systems offer a durable, energy-efficient, and cost-effective alternative to built-up and modified bitumen roofing.
Why Single Ply?
- Reflective, ENERGY STAR® rated membranes that reduce cooling costs
- Heat-welded or fully-adhered seams for a watertight bond
- Lightweight systems that can often be installed over existing roofs
- Resistant to punctures, UV exposure, and chemical damage
- Manufacturer-backed warranties on materials and workmanship
We are certified installers for leading single-ply manufacturers including Carlisle, GAF, and Johns Manville, and our crews are trained in proper seam-welding technique to ensure every roof performs for its full service life.
