Service for Columbus commercial properties
Silicone fluid-applied restoration extends the service life of eligible Columbus commercial flat roofs without tear-off — at roughly 25 to 40 percent of full replacement cost. The key word is eligible. Before we recommend silicone coating to any Columbus building owner, we assess eligibility with moisture cores and a written condition report.
Silicone roof coating is a fluid-applied restoration system: liquid silicone sprayed or rolled over an existing membrane at 20 to 40 mils dry film thickness, forming a seamless, UV-resistant, fully waterproof layer over the existing roof. On a Columbus commercial building where the coating is appropriate — dry insulation, sound membrane seams, adequate drainage — silicone adds 10 to 20 years to the existing system's service life at capital cost well below full replacement, with a manufacturer warranty and no tear-off disruption.

Service decisions are tied to leak history, roof age, membrane condition, drainage, tenant sensitivity, access, and the capital plan behind the property.
The next step is a repair scope, replacement budget, coating review, maintenance schedule, bid package, moisture survey, or immediate leak response plan.
Questions
No. Silicone coating is appropriate for roofs with dry insulation, sound membrane seams, and adequate drainage. Roofs with wet insulation, open seams, or significant ponding are not silicone candidates — the coating cannot address subsurface moisture, and Columbus's 28-plus freeze-thaw cycles per winter will expand any trapped moisture through the assembly. We pull moisture cores before recommending silicone coating. A roof that does not pass the moisture assessment needs insulation replacement, seam repair, or full replacement, not coating.
Ten to twenty years depending on applied thickness, surface preparation quality, drainage adequacy, and annual maintenance compliance. Columbus's UV load is lower than southwestern US markets, which extends silicone coating life relative to Columbus or San Antonio installations. The primary durability threats in central Ohio are chronic ponding — which degrades the coating at the waterline — and mechanical damage from HVAC maintenance foot traffic on rooftops that were not designated as traffic zones before coating.
On a Columbus commercial building where silicone coating is genuinely appropriate, the installed cost typically runs 25 to 40 percent of full TPO replacement cost — roughly $2.50 to $4.50 per square foot for a warranted silicone system versus $9 to $14 per square foot for full TPO replacement on most Columbus commercial buildings. That economic case is real for eligible roofs. It is not real on roofs that need insulation replacement or seam repair that the coating cannot address — applying coating to an ineligible Columbus roof defers a $12 cost into a $20 cost within three winters.
