Hong Kong gets between four and six tropical cyclones close enough to raise a signal in a typical year, and the Observatory has raised the No. 10 Hurricane Signal often enough in the last decade that nobody here treats it as theoretical.[1] What is far less well understood is which of the resulting damage a home insurance policy actually pays for.
The answer turns almost entirely on one distinction that has nothing to do with how bad the weather was: whether the water arrived suddenly or gradually. A window blown in during a No. 8 is one thing. A patch of damp that has been spreading since last summer is a completely different thing, and only one of them is an insurance question.[10]
This piece works through what a typical policy covers for typhoon and water damage, where the exclusions actually sit, why storm surge and flooding are treated separately from wind, and what to do in the hours after damage occurs.[8]

If you own a building rather than a flat, the practical side of keeping that cover right deals with a related and harder question.
Typhoon and Water Damage: The Deciding Distinction
Insurance responds to sudden, accidental, identifiable events. It does not respond to gradual deterioration, wear, or a problem that has been developing for months.[10]
That single principle explains most of what follows. A window that fails during a No. 8 and lets rain into the flat is a sudden event. Damp appearing along a wall over a season is deterioration. The weather may have contributed to both, and only the first is covered.
It also explains why claims are sometimes declined after a genuine storm. The insurer is not disputing that the typhoon happened. It is asking whether this particular damage was caused by the storm or merely revealed by it, and a roof or window that was already failing usually falls into the second category.[14]
What a Standard Policy Covers in a Typhoon
Broadly, and subject to the individual wording:
Wind damage. Damage caused directly by storm-force wind — broken windows, damaged doors, structural damage — is generally covered, on both the buildings and the contents side.[9]
Rainwater entering through storm damage. Once wind has broken the building envelope, the water that follows is usually treated as part of the same event and covered accordingly.[9]
Falling objects. Damage from a tree, scaffolding, or debris driven by the storm is normally covered. Hong Kong has a specific exposure here because of bamboo scaffolding and the density of building works.[2]
Contents damaged by the above. Furniture, electronics and possessions damaged by wind-driven rain entering through storm damage are covered under the contents section.[9]
Alternative accommodation. Where the home becomes uninhabitable after an insured event, most policies contribute to temporary accommodation.[14]
What is usually covered, and what usually is not
The left column is a sudden event. The right column is a condition. That distinction, rather than the severity of the weather, is what decides the claim.
Indicative. Policy wordings differ materially on flood and seepage — the schedule is the authority for your own cover.
Flood Is Not the Same Peril as Wind
This is where Hong Kong policies differ most from each other, and where the assumption that “typhoon cover” is one thing causes the most trouble.
Wind damage is core cover on essentially every policy. Flood — water rising from outside and entering the property at ground level — is frequently a separate peril that is either optional, sub-limited, or excluded entirely.[9]
The distinction matters more here than it might elsewhere because of storm surge. Severe typhoons in recent years have produced significant coastal inundation in low-lying areas, and the Observatory now publishes storm surge information alongside the wind warnings precisely because the two hazards are separable.[3] A property at ground or podium level near the water has a flood exposure that a flat on the twenty-eighth floor simply does not.[11]
Anyone in a low-lying, coastal or ground-floor property should check specifically whether flood is in the policy, and at what limit. It is the single most common gap in Hong Kong household cover.
The Seepage Problem
Water arriving from a neighbouring flat is its own category and it is the hardest one.
The government runs a Joint Office of the Buildings Department and the Food and Environmental Hygiene Department dedicated to investigating water seepage between premises, which tells you how routine and how contentious these disputes are.[4][5] The process establishes the source; it does not pay for the damage.
For insurance purposes, a sudden escape from a neighbouring flat — a burst pipe, an overflowing bath — will usually be covered under your contents policy, which then pursues recovery from whoever was responsible. A slow seep is generally limited or excluded, because it is deterioration rather than an event.[10]
Where household storm claims actually fail
The reasons we see most often behind a declined storm or water claim, roughly in the order we see them. None of the top three is about the severity of the weather.
The Reasonable Precautions Clause
Almost every household policy requires the insured to take reasonable steps to prevent loss or damage. During a typhoon that has practical content.[9]
Bringing in anything loose from a balcony, closing and securing windows, and moving valuables away from windows and off the floor are all things an insurer will reasonably expect. The Home Affairs Department and the Observatory both publish preparation guidance, and following it is not merely sensible but relevant to a subsequent claim.[6][7]
This is also where the falling-object exposure bites in both directions. Anything blown from your balcony that causes damage or injury below is your liability, and the Buildings Department treats objects falling from buildings as a serious public safety matter.[2]
What To Do in the First 24 Hours
The sequence matters, and it is short.
Make the property safe and prevent further damage — boarding a broken window, moving possessions clear of water. Policies generally cover reasonable emergency measures and generally require you to take them.[14] Keep receipts for anything you spend doing it.
Photograph everything before you clear up, including the damage in situ and the wider context showing where it came from. Once a room has been cleared, the evidence is gone.[8]
Notify the insurer promptly and in writing, even before you have the full picture. Notification periods are real and late notification is a genuine ground for decline.[8]
Do not dispose of damaged items until the insurer has confirmed you may. An assessor may want to inspect them, and disposing of them removes the evidence of value and condition.[8]
The four checks worth doing before the season
All four are short. Every one of them changes the outcome of a claim.
Whether flood is actually in the policy
Wind is core cover almost everywhere. Flood frequently is not, and for a low-lying, coastal or ground-floor property that is the exposure that matters.
The contents sum insured, at today’s prices
Under-insurance reduces every settlement proportionately, so a policy sized three years ago pays less than the owner expects.
A dated photographic record
Every room, the window frames and the balcony. This is what answers the assessor’s question about pre-storm condition.
That liability cover is in place
For anything that leaves your balcony, and for water that reaches the flats below. Neither is covered by the contents section alone.
How This Plays Out
The people below are fictional personas we have put together to show which options tend to suit which situations. They are not real clients. Our client information always remains 100% confidential.
Ground floor, wind covered, flood not — Charlotte*
*Fictitious persona based on situations we see regularly. We never reveal client information.
Charlotte* is forty-four and lives in a low-lying ground-floor property. A severe typhoon brought water in at floor level rather than through any wind damage.
Her policy covered wind, as almost all do, and did not include flood as a peril. The distinction is invisible until it matters. For anyone at ground or podium level near the water, the check worth making is specifically whether flood appears in the schedule and at what limit, because it is commonly optional rather than automatic.[11]
Damp for months, claimed after the storm — Wei*
*Fictitious persona based on situations we see regularly. We never reveal client information.
Wei* is fifty-six and had noticed damp along an external wall over the preceding year. After a typhoon he claimed for the resulting damage.
The insurer accepted that the storm occurred and declined on the basis that the damage was gradual. That is the standard and correct application of the wording. What tends to be more useful in this position is treating the damp as a maintenance and, where it comes from a neighbouring flat, a Joint Office matter, and dealing with it before it becomes large rather than waiting for a weather event to attach it to.[4]
Balcony furniture, damage below — Fiona*
*Fictitious persona based on situations we see regularly. We never reveal client information.
Fiona* is thirty-seven and left balcony furniture out during a No. 8 signal. It caused damage below.
Two separate issues arise. Her own claim engages the reasonable precautions clause, and the liability to the party below is a personal liability question rather than a contents one. On what she has described, the personal liability section of a household policy is what would respond, and it is typically the least expensive component of that policy and the one most often left out.[9]
How You Get the Storm and Water Damage Protection You Need
Typhoon damage is one of the few claims where the outcome is largely decided months before the storm, by whether the right perils are in the policy and whether there is any record of the property beforehand. Both are quick to fix and almost nobody does either.
We check flood specifically, not just storm
Wind is core cover on essentially every policy. Flood is frequently optional, and for a low-lying or ground-floor property it is the exposure that matters most.
We size the contents at replacement cost today
Under-insurance reduces every settlement proportionately, and a sum insured set a few years ago is almost always short.
We make sure liability is included
For anything that leaves a balcony and for water reaching the flats below. It is the least expensive section of the policy and the one most often missing.

Frequently asked questions
Does home insurance cover typhoon damage in Hong Kong?
Wind damage is core cover on essentially every household policy, along with rainwater entering through damage the wind caused, falling objects and the contents ruined as a result. What is far less consistent is flood, which is frequently a separate peril that is optional, sub-limited or excluded.[13]
Why was my claim declined when there was clearly a typhoon?
Because the insurer is not asking whether a typhoon occurred but whether this particular damage was caused by it or merely revealed by it. Insurance responds to sudden, identifiable events rather than to gradual deterioration, so damp that had been developing before the storm generally falls outside cover.[10]
Is flooding covered?
Not always. Flood is commonly treated as a separate peril from wind and may be optional, sub-limited or excluded. For a ground-floor, podium-level or low-lying coastal property this is the single most important thing to check, because storm surge in recent severe typhoons has produced significant coastal inundation.[3]
What about water coming from the flat above?
A sudden escape — a burst pipe or an overflowing bath — will usually be covered under your contents policy, which then pursues recovery. A slow seep is generally limited or excluded because it is deterioration rather than an event, and it is dealt with through the government’s Joint Office rather than through insurance.[5]
Do I have to close my windows for the policy to pay?
Effectively yes. Almost every policy requires reasonable steps to prevent loss, and during a typhoon that means securing windows and doors and bringing in anything loose from a balcony. The Observatory and the Home Affairs Department both publish preparation guidance, and following it is relevant to a later claim.[6]
Am I liable if something blows off my balcony?
Yes, where it causes damage or injury below. Objects falling from buildings are treated as a serious public safety matter in Hong Kong, and the exposure is a personal liability one rather than a contents one. The liability section of a household policy is what responds.[2]
What should I do immediately after damage?
Make the property safe and prevent further damage, keeping receipts for anything you spend. Photograph everything before you clear up. Notify the insurer promptly in writing even before you have the full picture. And do not dispose of damaged items until the insurer confirms you may.[8]
