A flat roof coating system in Columbus, Ohio typically costs $2.80 to $4.00 per square foot, while a full replacement runs $5.50 to $12.00 per square foot. For a sound commercial roofing system, coating often costs about half as much as a full replacement. Our team at Top Notch Commercial Roofing suggests replacement when wet insulation or deck damage makes coating a poor fit.

What Does Flat Roof Replacement Cost in Columbus, OH Include?
Flat roof replacement cost in Columbus, OH includes tear-off, disposal, new insulation, a new membrane, and new flashing. Disposal is a real cost. The U.S. Environmental Protection Agency reports that 600 million tons of construction and demolition (C&D) debris were generated nationwide in 2018. A coating skips tear-off, so your old roof stays out of the landfill.
When Does Commercial Roof Restoration vs Replacement in Columbus Make Sense?
Choose restoration when your membrane and deck are sound. Choose replacement when moisture has spread through the insulation or the deck is failing.
Good restoration candidates include:
- An aging EPDM roof on a Dublin office building with worn seams but dry insulation
- A modified bitumen roof on a Reynoldsburg retail strip with minor cracking
- A metal roof on a Grove City warehouse with surface rust and loose fasteners
Central Ohio freeze-thaw cycles widen small cracks each winter. Catching those cracks early through a commercial roof inspection keeps a commercial roof coating on the table. Waiting too long can force a full commercial roof replacement.
