A commercial roof inspection after a storm, done right: the 30-minute check your facility team can run safely the next morning, and when to call a roofer.
The storm went through overnight. By 8 a.m. someone will ask whether the roof is all right, and the honest answer at that point is usually "nobody knows yet." A commercial roof inspection after a storm doesn't have to start with a roofer on site. Most of what you need to know in the first hour can be found by your own facility team — from inside the building and from the ground — in about 30 minutes.
This post is that routine: what to check, in what order, how to record it so it is useful to a roofer or an adjuster, and where it stops being your team's job. It is written for property managers, building engineers and boards, not homeowners.
The National Roofing Contractors Association's position is blunt: after severe weather, owners should assess roof damage from ground level and leave closer assessment and repairs to a professional roofing contractor. NRCA has also told business owners to never climb onto a damaged roof to repair it themselves.
That shapes everything below. The morning-after check is built so that most of it never puts anyone on the roof. The one optional rooftop step is only for a team that already walks the roof under a written fall-protection program — and only when conditions allow.
Two timing rules before anyone moves:
Run it in this order. The inside of the building tells you where to look outside.
| Minutes | Where | What to check | Record |
|---|---|---|---|
| 0–10 | Top floor and stairwells | New ceiling stains, wet tiles, drips, water at window heads and along exterior walls | Photo of each stain with a tape or object for scale; room number |
| 10–12 | Mechanical rooms and the roof hatch from below | Water at the hatch curb, around ducts and pipes that pass through the roof | Photo, location |
| 12–20 | Ground-level walk around the building | Downspouts discharging, scuppers running, overflow scuppers running (a warning sign), metal edge or coping visibly lifted, debris or membrane pieces on the ground | Photos from fixed points; note which outlets were and weren't flowing |
| 20–25 | Upper windows, neighbouring roofs or a parking deck with a view | Displaced rooftop units, bent flashing, large branches on the roof, standing water across wide areas | Zoomed photos; never lean out of an open window |
| 25–30 | Office | Compile photos, mark them on a roof plan, decide: monitor, maintenance call, or emergency call | One-page summary with date and time |
A new stain directly below a rooftop unit, a drain or a wall points to a different cause than one in the middle of the floor plate. Mark every stain on a floor plan. Water travels along the deck and insulation before it drips, so the stain is a clue to the area, not the exact spot. That is the roofer's problem to solve — your job is to tell them where water came out.
Overflow scuppers or overflow drains running after the rain has stopped is the most useful thing you can see from the ground. Overflows are a backup. If they carried water, the primary drains were probably blocked or undersized for that storm, and water stood deeper on the roof than it should have. That is worth a call even if nothing has leaked yet.
Metal edge and coping are the parts most often lifted by wind, and once an edge lifts, the membrane behind it is exposed. If you can see a section standing proud from the ground, treat it as urgent.
Pieces on the ground — strips of membrane, flashing, insulation board, fasteners — mean something on the roof came apart. Bag them and keep them. They are evidence.
If your team already walks the roof under a written program, a short look from the hatch area can confirm what you saw from below. Only if the roof is dry, the wind has dropped and lightning is long gone. Never alone.
The OSHA low-slope rules under 29 CFR 1910.28(b)(13) still apply:
| Distance from the edge | Requirement |
|---|---|
| Under 6 feet | Guardrail, safety net, travel restraint or personal fall arrest |
| 6 to under 15 feet | The same, or a designated area for work that is both infrequent and temporary |
| 15 feet or more | The same, or a designated area — or, for infrequent and temporary work, an enforced rule that nobody goes within 15 feet of the edge without protection |
Skylights are holes; storm debris can hide them, and wind can crack their domes. Our fall roof maintenance checklist covers these rules in full.
On the roof, look — don't touch the membrane:
Anything near the perimeter — lifted edge metal, a damaged parapet cap, a hanging gutter — gets photographed from 15 feet back or more, and goes on the roofer's list.
A storm is when documentation pays for itself, whether the next step is a repair, a warranty call or an insurance claim.
If the damage looks like it will become a claim, our storm damage and insurance claims page explains how a roofer's condition report fits into it.
Call a roofer the same day if any of these turn up:
Active leaks are commercial roof repair territory and shouldn't wait for a scheduled visit. Everything else — the "it's probably fine but I want to know" findings — is what a professional post-storm inspection is for.

After any severe storm — high wind, hail, heavy rain or a named storm's remnants — yes. NRCA recommends an inspection after major weather events in addition to the routine spring and fall checks. For routine rain, your regular schedule is enough.
Only if they already work under a written fall-protection program, the roof is dry and calm, and lightning has passed. Otherwise the check is done from inside and from the ground, which is what NRCA recommends for owners.
You often can't from the ground. Wet insulation under an intact-looking membrane is common after wind-driven rain. A roofer can confirm with a moisture survey or core cuts.
Read your policy for its notice requirements, then get a qualified roofer to document the condition. A clear, dated condition report and your own photos make the conversation with the adjuster much easier.
