Perth's winter storm season reliably produces a wave of damaged vehicles, hail dents across bonnets and roofs, branches through windscreens, and cars caught in flooded carparks or low-lying streets. What's less obvious to most owners is that these damage types behave very differently when it comes to repair costs and resale value. Hail damage is often purely cosmetic. Water damage frequently isn't, even when the car looks fine and starts normally afterwards. This guide covers what actually happens to a storm or flood damaged vehicle, and how to think through the claim-versus-sell decision.
How Water Depth Affects a Flood Damaged Car in Perth
With flood damage, the single most useful predictor of outcome is how high the water got.
Below the door sills Generally the best case. Water hasn't entered the cabin, and damage is typically limited to underbody components. Often repairable without major consequences, though it's worth having brake lines, bearings, and the exhaust checked.
Above the sills, into the footwells Now it's serious. Water has reached carpet, underlay, seat rails, and often the wiring looms that run beneath the carpet and under seats. Even after drying, moisture trapped in insulation can cause corrosion and electrical faults that emerge weeks or months later.
Above the dashboard is almost always a total loss. At this level, water has reached the ECU, airbag control module, fuse boxes, and the bulk of the vehicle's electronics. Insurers rarely repair vehicles submerged this deep, because long-term electrical reliability can't be guaranteed.
Saltwater at any depth is significantly worse than freshwater at the same level, since salt accelerates corrosion aggressively and continues doing damage long after the vehicle has dried out. Relevant for coastal Perth suburbs and vehicles caught in tidal or storm-surge flooding.
Q: Is a flood damaged car worth anything?
A: Yes, though the value depends heavily on how deep the water got. A vehicle flooded below the door sills may be economically repairable with modest value loss. One submerged above the dashboard is typically a total loss for road use, but still holds value through undamaged components and scrap metal recovery.
Why Water Damage Is Worse Than It Looks
A flood-damaged car that starts and drives normally can still be a genuine problem vehicle, which is why insurers treat water damage so cautiously:
Corrosion continues after drying. Moisture trapped in seat frames, door cavities, and beneath carpet keeps corroding metal long after visible water has gone.
Electrical faults emerge gradually. Water-affected connectors and control modules often work initially, then develop intermittent faults weeks or months later as corrosion spreads through pins and circuit boards.
Mould and bacterial growth. Trapped moisture in insulation and upholstery creates persistent odour and air quality issues that are difficult to fully resolve.
Airbag systems can be compromised. Water in an airbag control module is a genuine safety concern, and these modules are expensive to replace.
Q: Can a water damaged car be repaired?
A: It depends on depth and water type. Vehicles with water below the door sills are often economically repairable. Once water enters the cabin and reaches wiring, seat rails, and control modules, repairs become expensive and long-term reliability is uncertain which is why insurers frequently write off deeply flooded vehicles rather than repairing them.
Hail Damage Is a Different Situation Entirely
Hail is the most common storm damage in Perth, and it behaves very differently from flooding. Hail damage is typically:
Purely cosmetic dents in panels, roof, bonnet, and boot, with occasionally cracked glass
Mechanically irrelevant the engine, transmission, and drivetrain are unaffected
Expensive to repair properly paintless dent removal across an entire vehicle can run into thousands, and severe hail often exceeds a car's value in repair costs
This creates a common situation: a mechanically excellent vehicle that's been written off purely because panel repairs exceed its market value. These cars retain substantial value, since everything that makes a car mechanically valuable is entirely intact.
Q: Does hail damage affect a car's mechanical condition?
A: Generally no. Hail damage is almost always cosmetic, affecting panels and sometimes glass while leaving the engine, transmission, and drivetrain untouched. A hail-damaged vehicle can be written off on repair cost alone while remaining mechanically sound, which is why these vehicles retain meaningful value.
Should I Claim on Insurance or Sell?
This is the practical decision most owners face, and it's worth thinking through rather than defaulting either way.
Consideration | Points Toward Claiming | Points Toward Selling |
Damage severity | Repairable, below your excess threshold in significance | Repair cost approaches or exceeds vehicle value |
Excess amount | Low excess relative to repair cost | High excess makes claiming marginal |
Premium impact | Minimal, or you have protected no-claim status | Claim would meaningfully increase future premiums |
Vehicle age | Newer car worth restoring properly | Older car where repairs exceed sensible investment |
Repaired resale value | Repair won't significantly affect future value | Repaired flood history will permanently reduce value |
A point worth knowing: if you claim and the insurer declares the vehicle a total loss, they typically take ownership of the wreck in exchange for the payout. Some owners prefer to retain the vehicle and handle its disposal themselves, which may be negotiable with the insurer at a reduced settlement worth asking about if you'd rather control that outcome.
Q: Should I claim storm damage on my car insurance?
A: Compare your excess and likely premium increase against the repair cost. Claiming usually makes sense when repair costs substantially exceed your excess. For older vehicles where repairs approach the car's total value, selling as-is can be the more practical outcome, and it's worth getting a quote before committing to a claim so you can compare both figures.
Acting Quickly Matters With Water Damage
Unlike hail, where the damage is done and won't worsen, flood damage actively deteriorates. Every week a water-affected vehicle sits, corrosion spreads and electrical damage compounds. A few practical steps:
Don't try to start it if water reached above the sills attempting to start a flooded engine can cause hydrolock and turn recoverable damage into catastrophic damage.
Document everything with photos immediately, including water lines visible inside the cabin, for any insurance claim.
Disconnect the battery if it's safe to do so, to reduce the risk of electrical shorts.
Get it assessed or sold promptly. Value declines meaningfully the longer a flooded vehicle sits.
Q: What should I do immediately after my car is flooded?
A: Don't attempt to start it if water reaches above the door sills, as this risks severe engine damage. Photograph the damage including internal water lines for insurance purposes, disconnect the battery if safe, and arrange assessment or sale promptly, since flood damage worsens the longer a vehicle sits.
Reducing Your Risk Before the Next Storm
Perth's storm season is predictable enough that a few habits meaningfully reduce the odds of ending up with a damaged vehicle:
Park undercover when warnings are issued. Bureau of Meteorology severe weather warnings typically give enough notice to move a vehicle into a garage, carport, or covered parking.
Avoid parking under large trees during storm season. Falling branches cause a significant share of storm-related vehicle damage, and the damage is often severe roof, windscreen, and panel damage from a single branch.
Know which local roads flood. Most Perth suburbs have a few known low points that pool water during heavy rain. Avoiding these during downpours is far cheaper than dealing with the aftermath.
Never drive through floodwater of unknown depth. Water deeper than it appears is the most common cause of vehicles becoming flood write-offs, and it's entirely avoidable. If you can't see the road surface, don't drive through it.
Check your insurance covers floods specifically. Some policies treat flood differently from storm damage, so it's worth confirming rather than assuming.
Keep your excess amount in mind. Knowing your excess before a claim situation arises makes the claim-versus-sell decision faster when you're under pressure.

Frequently Asked Questions
These questions come up frequently after Perth storm events.
Q: Will my comprehensive insurance cover storm damage?
A: Comprehensive policies generally cover storm, hail, and flood damage, though specific terms and exclusions vary. Check your policy wording or contact your insurer directly to confirm what applies to your situation.
Q: How much does hail damage reduce a car's value?
A: It depends on severity, but significant hail damage can reduce a vehicle's market value substantially despite having no mechanical impact, since the repair cost for full panel restoration is high.
Q: Can I sell a storm damaged car that's still driveable?
A: Yes. Driveable storm-damaged vehicles can be sold normally, and WA doesn't require a roadworthy certificate for a vehicle sale regardless of condition.
Q: Is a flood damaged car recorded in its history?
A: If an insurer writes off a vehicle due to water damage, it's recorded on the Written-Off Vehicles Register and visible on a PPSR check permanently.
Q: Should I get a quote before accepting my insurance payout?
A: It can be worth comparing, particularly if you're considering retaining the vehicle rather than surrendering it to the insurer. Getting an independent quote costs nothing and gives you a clearer picture of your options.

Final Thoughts
Storm damage isn't one category hail and flooding produce completely different outcomes, and treating them the same way leads to poor decisions. A hail-damaged car with an intact drivetrain holds real value. A deeply flooded car often doesn't, and declines further the longer it sits. Either way, comparing an independent quote against an insurance settlement before committing gives you a clearer view of the choice you're actually making.
