Resources · Commercial property
A commercial property loss in Ohio runs through the same appraisal clause a homeowner's does. The demand reads about the same. The panel works the same way. What changes is the building, and on a commercial file the building is most of the number. Three things move that number in ways a house file never has to account for.
Appraisal decides the amount of a covered loss, and it decides nothing else. Whether the policy responds at all is a coverage question a panel has no authority over. That's as true on a distribution warehouse as on a ranch house in Powell, and the process for invoking it doesn't change either.
What changes is what the number is made of. A commercial roof isn't a flatter version of a residential one, and the equipment on top of it has no residential equivalent. Time behaves differently too, and the party whose property got damaged isn't always the party holding the policy.
This page is an informational overview of how commercial property losses get valued. It isn't legal advice, and your policy's exact language controls everything described below. Ironclad Assessment Group serves as a neutral appraiser and umpire. We're not a public adjuster, and we don't adjust, negotiate, interpret your policy, or settle your claim.
A house is close to an envelope. A commercial building is a set of systems sharing a shell, and each one gets valued on its own terms.
Start on the roof. Low-slope assemblies behave nothing like shingles. TPO is a single-ply membrane heat-welded at the seams. EPDM is rubber, seamed with tape or adhesive. Modified bitumen goes down in plies. A built-up assembly is felt and asphalt in layers under gravel or a cap sheet. Each fails its own way and gets repaired its own way, so a line item that's routine on one assembly means nothing on another.
Then comes the argument on nearly every roof file. Can the membrane be patched, or does the field come off in sections? An isolated puncture is a patch. Punctures scattered across a field, or seams opened along a run, are a different conversation, and two careful estimators land in different places on it. Wet insulation is its own question, because a patch over saturated board doesn't put the assembly back.
Above the membrane sits everything a house doesn't have. Condenser coils raise their own argument, usually whether bent fins get combed or the coil gets replaced. Rooftop units, curbs, ductwork, gas piping, exhaust fans, hatches, and equipment screens belong on the list too. Around the perimeter there are coping metal, counterflashing, pitch pans, roof drains, scuppers, and the overflow outlets that matter the day a drain plugs. Any one of those can appear on one valuation and be absent from the other.
Inside, the list keeps going. Suspended ceiling grid and tile rarely come apart cleanly. Fire suppression piping, walk-in refrigeration, electrical gear, and commercial flooring price differently than their residential cousins. On a multi-story building, water that starts at the roof reaches floors that read fine from the doorway.
In Ohio, commercial work falls under a statewide commercial building code, separate from the residential code that governs one-, two-, and three-family dwellings. What a local inspector in Columbus calls for on a given job is a separate matter from what an older desk estimate assumed.
Commercial policies commonly carry a time-element coverage alongside the property damage. Business income covers the operation while the space can't be used, and extra expense covers what it costs to keep running somewhere else. Both run against a period of restoration the policy defines on its own terms.
Whether a dispute over that side belongs inside an appraisal panel's authority is genuinely contested. Some clauses are written narrowly, around the amount of loss to property. Others are worded broadly enough that people argue they reach the time-element figure too. There isn't one settled answer to point to.
What's not in doubt is the property damage side. That's squarely what the appraisal clause was built for. The time-element side may or may not travel with it, depending on what the policy in front of you says.
We won't tell you which way your clause reads. Nobody selling an appraisal should. That one goes to the policy language and to a policyholder-side insurance attorney, and it's worth answering early.
On a house, the owner of the building and the owner of the policy are usually the same person. Commercial files aren't built that way.
Tenant improvements and betterments are the usual complication. A tenant builds out a space with partitions, finishes, casework, and specialty electrical. That work becomes part of the building while remaining, for insurance purposes, something the tenant may carry. Which policy responds, and who's obligated to put it back, come out of the lease and the policies. Not out of an appraiser's judgment.
There's also the question of who's at the table. One loss can involve a building owner, several tenants, a lender with an interest in the property, and separate carriers looking at overlapping damage. The valuation has to be broken out clearly enough that the right figure lands with the right party. That's one good reason for an award itemized by category.
Larger losses carry longer lists, and a longer list means places where two valuations can differ. That isn't a sign anything went wrong. It's arithmetic. A file can run to hundreds of line items across the roof assembly, the mechanical inventory, the tenant spaces, and the exterior envelope. Two appraisers working independently agree on much of it and separate on the rest.
That's what the panel structure is there for. The two appraisers close what they can close, and the umpire decides only what's still open. On a large commercial file that last step tends to carry real weight.
Two other things get confused with the panel's work. Coinsurance provisions and policy limits are policy mechanics that can affect what ultimately gets paid. They operate separately from the amount of loss the appraisers determine. A panel values the damage. What the policy does with that figure is governed by its own terms.
A valuation is only as good as the record underneath it, and on a commercial file that record has a shape.
The roof assembly comes first, meaning what membrane is on the building, what sits under it, when it went on, and whether it's original or a recover over something older. The mechanical inventory follows, unit by unit, with make, model, capacity, age, and location. Then the interior, floor by floor and tenant space by tenant space.
Prior repairs matter as much as anything on the list. A patched roof carries a history, and that history shapes both what the damage is and what putting it back involves. Photographs with something in the frame for scale do a lot of the work later. The lease belongs in the file too.
Our fee is set in writing before the engagement begins and never depends on the size of the award. That's what keeps the number credible. Nobody bought it. The full picture of what we do as appraiser and umpire is on the services page.
The property damage side is squarely what appraisal is built for. Whether a time-element figure belongs inside the panel's authority is contested, and it turns on how your clause is written, with no settled answer to point to. Put that one to your policy language and a policyholder-side insurance attorney.
When the disagreement is about what the repair involves and what it costs, that's amount of loss, and the clause was built for it. If the argument is whether the policy pays for that category of work at all, that's coverage, and a panel doesn't reach it.
It depends on who holds the policy containing the clause and on what the lease says. A tenant carrying its own coverage on improvements and contents usually has a clause of its own to work with. Which items belong to which policy is a lease-and-policy question.
