# Roof Recover Systems > Commercial roof recover scoping for Columbus buildings, single-ply recover over existing systems, modified bitumen recover, and the moisture assessment that determines whether recover is the right capital decision for Franklin County commercial buildings. Canonical: https://commercialrooferscolumbus.com/services/roof-recover-systems Scroll Service for Columbus commercial properties A roof recover installs a new membrane over the existing system without full tear-off, cutting replacement capital cost by 30 to 50 percent when the existing roof qualifies. The qualification question is the same on every Columbus building: is the insulation dry? Our project managers at in the Arena District run the moisture assessment that answers that question before any recover scope is produced. Roof recover is not a corner-cutting option. Properly scoped and executed on a building that qualifies, it delivers a warranted 15 to 20-year roof asset at roughly half the cost of full tear-off replacement, without the debris hauling, the dumpster logistics, or the extended disruption that tear-off produces on occupied Columbus commercial buildings. The phrase that separates a sound recover from a deferred replacement failure is properly scoped.

Questions ## Roof Recover Systems questions ### Does Ohio building code allow a recover layer over an existing Columbus commercial roof? Ohio Building Code, aligned with IBC 2021, generally allows one recover over an existing single roofing layer before tear-off is required, so most Columbus commercial buildings with one existing layer are eligible for recover consideration. Buildings with two existing roofing layers are required to tear off before adding another layer. We confirm the layer count and the relevant Columbus-area jurisdiction's permit interpretation before finalizing any recover scope. ### What manufacturer warranty is available on a Columbus roof recover? Major single-ply manufacturers offer 15 to 20-year no-dollar-limit warranties on properly documented recover installations, the same warranty terms available on new replacement installations, provided the insulation cores are dry, the existing membrane is compatible with the recover system, and the recover board meets manufacturer substrate specifications. Warranty issuance requires the manufacturer's pre-installation inspection documentation. We coordinate all warranty enrollment steps as part of the recover scope. ### How does a recover affect the next replacement cycle? A recover adds one additional roof layer. When the recover system reaches end of service life, the Columbus building will require full tear-off of two layers, the original membrane and the recover system, rather than a single-layer tear-off. Two-layer tear-off costs proportionally more, and this incremental future cost should factor into the recover lifecycle analysis. We include the two-layer future tear-off cost in every recover financial comparison we produce.
