What Drives Your Commercial Roof Price?
- Membrane type — the biggest single variable (see table above)
- Tear-off — removing the old roof adds $1.25–$2.50/sq ft
- Insulation — Ohio's 2021 code now requires R-25 continuous insulation; older buildings upgrading add real cost
- Roof complexity — penetrations, curbs, skylights, and multiple levels increase labor
- Access — crane requirements and difficult staging raise costs
- Material prices — up 18–22% since 2021, which is why locking in an estimate now protects you
Will Insurance Cover My Roof Cost?
If your roof was damaged by hail, wind, lightning, or a storm, your replacement may be covered by commercial property insurance — meaning you'd pay only your deductible on an RCV policy. Ohio sees frequent severe weather, and many building owners have a legitimate claim they've never filed. We document storm damage and help you pursue (and appeal) claims.
The Cheapest Roof Isn't Always the Lowest Bid
EPDM has the lowest upfront cost, but its dark surface raises HVAC bills — over 25 years, white TPO's energy savings often erase the difference. And the genuinely cheapest option, when your roof qualifies, is usually coating restoration at roughly half the price of replacement. The only way to know your best value is a real inspection.
