Storm Response
The hours after a storm are when owners make the decisions that determine whether a claim is paid in full, paid in part, or contested. The pressure runs the other way: water is coming in, tenants are calling, and the first contractor on the property is selling an emergency repair. A disciplined response protects the building, the warranty, and the insurance recovery at the same time — and most of it is documentation and sequencing, not construction. This is the framework we work from when we manage a post-storm response for an owner, and it applies whether the event is a single hailstorm or a regional wind event that hits a dozen assets at once.
The first 72 hours
The immediate priority is to stop active water intrusion and prevent secondary damage, and an owner has both a right and a duty to do so. But emergency mitigation is not the same as permanent repair, and the two should never be conflated in the rush. Temporary measures — tarping, sealing penetrations, clearing storm-clogged drains — buy time without prejudicing the claim, provided they are documented before and after. Most insurance policies obligate the owner to mitigate; failing to act can itself reduce a recovery when downstream water damage was preventable.
Documentation done in this window is worth more than any document created later, because it is contemporaneous and difficult to dispute. We capture dated, geotagged photographs of every affected area, the path of water entry, and the interior damage, alongside written notes on what was observed and when. The single most common reason a storm claim erodes is that the owner cannot show the condition of the roof immediately after the event as distinct from pre-existing wear. Photographs that establish both the damage and its timing are the foundation everything else is built on.
- Photograph all damage with date and location before any work begins, then again after mitigation
- Perform only emergency mitigation — stop water, protect contents — and keep all receipts and invoices
- Notify the carrier promptly and record the claim number, adjuster name, and every communication
- Do not authorize permanent repairs or sign a contractor's scope until the loss is properly assessed
- Preserve damaged materials and debris where feasible until the adjuster has inspected the roof
- Identify whether more than one peril is in play — wind, hail, and resulting water intrusion may sit under different policy provisions
Storm damage versus pre-existing condition
The contested ground in nearly every commercial roof claim is causation. The carrier's position is often that the damage reflects age, deferred maintenance, or prior wear rather than the named storm. This is where owners who maintain a current roof condition record hold a decisive advantage. A recent inspection report, infrared moisture survey, or reserve-study roof assessment establishes the pre-storm baseline, making it far harder for an adjuster to attribute fresh damage to long-standing deterioration. The absence of that baseline is precisely what carriers rely on to discount a claim.
Different perils leave different signatures, and naming them specifically matters. Hail produces bruising, fractured granules, and soft spots in the membrane; wind lifts, peels, or tents the membrane at seams and perimeters; impact debris punctures; and storm-clogged drains produce ponding that loads the structure. Those signatures present differently across TPO, EPDM, modified bitumen, and built-up systems. An assessment that names the peril, the mechanism, and the affected systems by type carries far more weight with an adjuster than a general report of leaks, because it ties the observed damage to the event rather than to time.
The independent assessment
We advise owners to obtain a roof condition assessment from a party whose interest is the building, not the repair revenue. A contractor pricing the job and a public adjuster pricing the claim each have a position; a roofing consultant's documentation is harder for a carrier to discount as self-serving. On larger losses, that independent record frequently becomes the anchor for the entire negotiation, and it gives the owner a defensible scope to test both the carrier's estimate and any contractor's bid against.
The contractor pressure you should expect
After a widespread storm, the supply of roofing labor tightens and the marketing intensifies. Crews canvass affected areas, offer to handle the insurance claim, and press owners to sign before an independent assessment exists. Some of these contractors are competent; the problem is structural, not personal — a party that profits from the size of the repair should not also be defining the size of the loss. Signing a scope or an assignment of benefits under that pressure routinely commits an owner to work, and to a price, that the actual damage did not require.
The protective sequence is simple to state and easy to abandon under stress. Document the loss, notify the carrier, complete only emergency mitigation, and obtain an independent assessment before any permanent scope is authorized or any claim-handling agreement is signed. The few days that sequence costs are almost always recovered in a cleaner claim and a repair scoped to the building's real needs rather than to a canvasser's revenue.
- Decline to sign permanent-repair contracts or assignment-of-benefits forms in the first days after a storm
- Keep emergency mitigation minimal, reversible, and separately invoiced from any permanent work
- Require that any permanent scope reconcile to the independent assessment, not the other way around
- Verify the repairing contractor's manufacturer approval before they cut into a warrantied membrane
Protecting the warranty while you respond
Emergency repairs done by whoever is available can void a manufacturer's roof warranty, and owners often discover this only when they later file an unrelated claim and find coverage has lapsed. Many membrane warranties require that repairs be performed by an approved applicator using approved materials and details. Where time allows, even emergency work should be routed through a contractor who holds the relevant certification, and the warranty terms should be checked before anyone cuts into the membrane.
There is a real sequencing tension here — stopping water cannot always wait for a certified crew — and the resolution is to keep the truly urgent mitigation minimal and reversible, then bring permanent repairs into compliance with the warranty once the emergency passes. Keeping records of who performed what work, with which materials, and on what date preserves the warranty position either way and gives the manufacturer no clean basis to deny coverage later.
It is also worth distinguishing the manufacturer warranty from the contractor workmanship warranty, because a storm response can affect both. The manufacturer warranty covers the membrane and its components; the workmanship warranty covers the installation and is only as good as the contractor still standing behind it. Storm repairs performed by an outside crew can leave an owner with a roof that no longer has a single accountable party for the original installation. We document the storm scope in a way that keeps the original warranties intact wherever possible and, where a repair must depart from them, makes that departure a known and deliberate decision rather than an accidental forfeiture discovered years later.
How we run a post-storm response
When we manage a storm event for an owner, our role is to coordinate the response so no single party's incentives drive the outcome. We document the loss independently, interface with the carrier and adjuster on the owner's behalf, scope permanent repairs against both the warranty and the building's longer-term capital plan, and make sure the storm is neither used as an excuse to over-repair nor under-settled because the damage was poorly recorded. We also keep the storm decision aligned with the roof's place on its life cycle — a roof already near replacement may warrant a different settlement strategy than one with years of service left.
Across a portfolio, the work begins before the storm. We keep condition baselines current, maintain a record of each roof's system type and warranty status, and pre-identify approved contractors in each region so that response is a matter of executing a plan rather than improvising one. The owners who recover the most after a storm are the ones who documented their roofs before it arrived, and our job is to make sure the next event starts from that documented position of strength rather than a scramble.
