TPO Roofing in Godfrey and the Riverbend
TPO (Thermoplastic Olefin) is the dominant commercial single-ply membrane on flat and low-slope buildings in Godfrey and across the Riverbend. It reflects UV, welds at the seams for long-term watertightness, and prices below EPDM and PVC alternatives in most building configurations. Trill Roofing installs, repairs, and inspects TPO membranes for commercial property owners in Godfrey, Alton, Edwardsville, and the rest of Madison and Jersey County. 60-mil and 80-mil systems, mechanically fastened or fully adhered, on commercial buildings from 5,000 to 100,000 square feet.
Why is TPO a good roof for a commercial building?
TPO membranes match Godfrey commercial roofing economics and Illinois climate well.
- UV reflectivity: White TPO surfaces reflect ~80% of solar radiation, cutting HVAC cooling load through Riverbend summers.
- Heat-welded seams: Hot-air welded seams create a single continuous membrane, eliminating the seam tape failure mode that affects older EPDM and modified bitumen systems.
- Wind uplift performance: 60-mil mechanically fastened TPO achieves Class A wind uplift ratings under FM 4474, important for the Riverbend’s spring derecho-strength wind events.
- Hail resistance: 80-mil TPO and 60-mil with reinforced scrim better resist Class 3 and 4 hail common in Madison County summer storms.
- Manufacturer warranties: 20, 25, and 30-year material warranties from GAF, Carlisle, Firestone, and Johns Manville on systems Trill installs locally.
- Cost: 60-mil TPO typically lands at the low end of commercial single-ply pricing in the Riverbend, with 80-mil adding ~15-20% for added impact resistance.

Great business to work with. My house, garage and studio now have matching shingles on the roof. Guttering was added to the house. Prompt service and fair pricing. -
I am very pleased with the total roof replacement and attic vents installation completed last week by Andy’s crew. Andy was reachable and responsive through the entire process! No question was too big or small! His crew had to stay an unplanned … More second day because of the steepness of my roof. There was not an ounce of frustration shown. I am pleased with the workmanship of his crew! They worked non-stop for two days, well into the evenings! At the end, I noticed a couple things to tweak and they did it without question or hesitation. I would highly recommend them! -
Trill Roofing went above and beyond on our roof. I have an old house. The roof had been untouched for many years. Much of the sheathing had to be replaced as well as rafters. In a time when it’s hard to get contractors to show up, … More Trill Roofing was on site, working on my roof exactly when they said they would start. They explained the process and answered all of my questions. I learned a lot about roofing systems.
I look forward to working with Trill on my upcoming siding and gutter projects. -
Andy, at Trill Roofing, is awesome to work with. We had storm damage, which insurance denied. Andy went the distance, he took multiple pictures which confirmed the damage, sent them to the insurance, and they finally approved roof replacement. … More None of the other roofing companies did that. They did an awesome job! Very quick and efficient. We highly recommend them.
