Full-Tear-Off Commercial Roof Replacement in Madison County
Aging commercial roofs in Illinois show up as failed seams on TPO, brittle EPDM at the membrane edges, ponding water, and saturated insulation. When repair stops being economical, Trill Roofing handles the full commercial replacement: existing membrane and insulation tear-off, deck inspection, insulation upgrade to current IL Energy Conservation Code, new TPO, EPDM, or modified bitumen membrane installation, and termination details at edges, penetrations, and curbs. Andy Pfleger walks every commercial bid, files the Madison County permits, and is on-site during major phases.
What’s Included in a Commercial Roof Replacement
Every commercial replacement Trill performs follows the same scope.
- Tear-off: Existing membrane and insulation removed, debris hauled off, deck exposed for inspection.
- Substrate inspection: Wet insulation flagged, deck condition evaluated, structural deflection noted.
- Insulation upgrade: Board insulation rebuilt to current IL Energy Conservation Code (R-30 average for commercial flat roofs).
- Membrane installation: TPO (60-mil or 80-mil), EPDM (60-mil or 90-mil), modified bitumen, or standing seam metal panels, depending on building use and budget.
- Termination details: Edge metal, parapet wall flashing, drain reconstruction, penetration boots, curb flashing for HVAC.
- Warranty registration: Manufacturer warranty filed (typically 20 to 30 years on TPO/EPDM systems) plus Trill workmanship warranty.

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.
