In short: Walk the building in order — grounds first, then the exterior envelope, then the interior — as soon as it's safe and before cleanup starts. Photograph everything before touching it, log tenant reports with dates, and bring in a storm damage contractor for anything on the roof you can't verify from the ground. The inspection isn't just good management; it's the evidence your insurance claim will be built on.
The storm has passed, the tenants are calling, and you have one job before the contractors, the adjusters, and the cleanup crews arrive: document what the storm actually did, in the right order, while the evidence is undisturbed. A disciplined walkthrough takes about 30 to 60 minutes on a typical commercial property — and it protects you twice over, once with your tenants and once with your carrier.
What should you check before you touch anything?
Start with safety, from the ground, before you set foot inside. Downed power lines, leaning trees or signage, and debris on the roof edge are all reasons to keep tenants back until they've been dealt with. If you smell gas, leave the building and call the utility. If a ceiling has visibly bowed from water weight, keep everyone out from under it — wet drywall and insulation are far heavier than they look.
This pre-check takes five minutes and it sets the rules for everything after: if the structure or utilities look compromised, the inspection waits for professionals. Your checklist is only useful if you're around to file it.
What's the right order for the walkthrough?
Go grounds, then envelope, then interior. There's a reason for this order: hazards on the grounds dictate what you can safely do everywhere else, the exterior envelope tells you where the building was breached, and the interior confirms whether water actually got in.
Grounds and site. Walk the perimeter with your phone camera. Photograph the building from all four sides before you approach — these wide shots establish the overall condition. Note displaced equipment, toppled dumpsters, damaged signage, broken fencing, and debris fields. Debris tells you about wind direction and force, which matters when you describe the loss. Check parking lots and loading docks for standing water and drain inlets that are clogged with leaves and branches — flooding at the ground level often starts at a blocked drain, not a roof breach.
Exterior envelope. Look up: gutters and downspouts pulled away from the building, dented or missing coping on parapets, broken windows or storefront glazing, torn awnings, and damaged facade panels. Siding or cladding that's lifted at the edges is a sign of wind uplift that often extends to the roof. Anything you can photograph with a zoom from the ground goes in the file now; anything that requires a ladder can wait for the contractor.
Roof — from where you stand. Most commercial roof problems are visible without stepping onto the surface: flashing peeled back at parapets, membrane that looks scuffed or displaced, ponding water sitting where it shouldn't, drains clogged with storm debris, and rooftop equipment that's shifted on its curbs. If you can see any of these from an adjacent building, a higher window, or simply with binoculars, document it. Hail marks on rooftop equipment — dented vents, damaged condenser fins — are also worth photographing, since they corroborate a hail event even when the membrane damage isn't visible from below.
What interior signs mean water got in?
Start at the top of the building and work down. Water travels: a ceiling stain on the third floor may originate from a roof breach, while a ground-floor stain may trace to a failed window seal or rising water.
Look for the classic trail — stained or sagging ceiling tiles, bubbling paint, damp drywall, water lines on walls, and musty odors that weren't there last week. Check mechanical rooms, elevator pits, and electrical closets: water in these spaces is both a damage problem and a safety problem. Open dropped ceilings where stains appear; the plenum above often shows the actual entry path. In basements and ground floors, note the high-water line if flooding reached the interior — that line establishes the event's severity more convincingly than any description.
Photograph every sign with your timestamps on, from wide to tight, and note the location in the building. Interior evidence often surfaces hours after the storm as water migrates through assemblies — it's normal to do this interior pass again a day or two later.
How should you log tenant reports?
Tenants are your distributed sensor network, and their reports frequently surface damage the manager never sees — a leak inside a tenant's buildout, a window that flexed in the wind, a door that no longer latches. Create a simple log: tenant name, suite number, date and time of the report, and a one-line description of what they observed.
Verify each report in person and photograph it. A tenant's "small drip" can turn out to be the visible edge of a much larger breach, and their timestamp helps pin the damage to the storm event. Forward serious reports to the owner promptly — and if a unit is uninhabitable, document the condition before any cleanup, since habitability disputes are the most common tenant conflicts after storms.
When should you call a storm damage contractor?
Call one when the inspection turns up anything you can't fully characterize from the ground: roof breaches, suspected membrane damage, structural concerns, or water intrusion with an unclear source. A professional storm damage assessment typically takes an hour or two on site and produces a written scope — that document becomes the backbone of your claim file and your repair bids.
There's a timing reason too: emergency mitigation is expected by your policy, and a contractor can tarp a breach or board an opening the same day. Every day a breach stays open is another day of preventable secondary damage that a carrier can refuse to cover. If you manage multiple properties, having a contractor on call before storm season is one of the highest-leverage things you can do — request an inspection or look at our storm damage services to see what a professional assessment covers. If you need to match a vetted repair partner to a property in a storm area, our business partner program exists for exactly that.
What belongs in the claim file when you're done?
By the end of the day, your file should contain: the storm's date and event details, your dated photos in wide-to-tight order, your walkthrough notes, the tenant report log, the contractor's written scope if you've had the assessment, and receipts for any emergency mitigation. Our storm damage documentation checklist covers the photo protocol in detail.
The managers who navigate claims smoothly aren't the ones with the least damage — they're the ones who documented what they had, in order, before the cleanup started. Thirty minutes of disciplined inspection on day one saves weeks of arguing about what the storm did on day ninety.
Frequently asked questions
How soon after a storm should a property manager inspect the building?
As soon as it is safe to walk the site — ideally the same day, in daylight, and before any cleanup begins. An early inspection lets you photograph damage undisturbed, which ties it to the storm event for insurance purposes. If roads are blocked or the structure looks compromised, wait for clearance; your safety comes before the checklist.
Should a property manager go on the roof after a storm?
Only if it is safe to do so and you are comfortable on roofs — storm damage can leave surfaces slippery, membranes punctured, and parapets weakened. From the ground or a neighboring vantage, binoculars can reveal most of what you need for a first pass: missing flashing, displaced membrane, clogged drains, displaced equipment. For a real condition assessment, bring in a contractor who does storm damage inspections regularly.
What if tenants report damage the manager can't see?
Log every tenant report with the date, the unit, and what they describe — then verify it yourself and photograph it. Interior water staining, for example, often appears hours or days after the storm while the roof breach happened immediately. Tenant reports are legitimate evidence; include them in your claim file and your inspection notes.
Does a post-storm inspection actually help an insurance claim?
Yes, in two ways. First, dated photos from a prompt inspection establish that the damage was caused by that storm event — carriers routinely challenge this when months pass between the storm and the documentation. Second, the inspection starts the clock on your duty to mitigate: once you've found a breach, the policy expects you to protect it from further harm.
