Damage from weather events

Storm damage: not every gust of wind automatically results in a payout.

Many policies apply a wind-speed threshold — often force 8 on the Beaufort scale — below which damage to roof, façade or outbuilding is not covered. We assess the actual cause, retrieve the KNMI data and make sure repair costs match the damage.

Good to know

What Krantz & Polak does in a storm damage claim

Storms, whirlwinds and hail leave a typical pattern: roof tiles loose or gone, an outbuilding dislodged, gutters bent, fences down, sometimes a tree on the roof. Often it concerns building damage whose true extent only becomes visible when the first rain afterwards comes through the roof.

We look at three things at the same time: what is the actual damage, is the policy being applied correctly, and is the repair offer reasonable.

On-site damage assessment

A storm or hail damage assessment requires someone willing to go up onto the roof. We systematically map tiles, insulation, gutters, dormers and façade elements. With hail we also look at less visible damage: dented zinc rolls, hairline cracks in roof panels, micro-impacts on solar panels that still work today but will fail within a year.

Wind force and KNMI data

This is often the key defence by insurers. The policy responds from a certain wind force — usually 7 or 8 Beaufort — and the insurer refers to the KNMI to demonstrate that the threshold was not met. But wind force is an average over ten minutes at a given station. A 100 km/h gust can occur locally without the measuring station ten kilometres away reporting a high average wind force. And in the case of whirlwinds, the measurement does not apply at all — there, eyewitness statements, other affected roofs in the area and any KNMI reports of local phenomena all count.

We collect those data in full and determine whether the insurer’s application of the policy stands up.

Hail damage

Hail produces its own damage pattern. With large hailstones — from around 2 cm and certainly above 4 cm — significant damage amounts arise in a short time. Insurers apply their own conditions for specific risks (particularly crops, vehicles and solar panels), sometimes with a minimum hailstone diameter. In business interruption claims in the agricultural sector, courts have repeatedly held that such a requirement cannot be invoked without limit — the actual damage and the policy context count.

With hail on a roof we pay attention to the difference between visible and functional damage. Light dents in zinc may not always be repairable; they may have halved the lifespan of the material. That ought to be factored in.

Policy conditions under scrutiny

We test your policy for:

  • Wind-force threshold and burden of proof: rightly invoked or not?
  • Exclusion for ‘overdue maintenance’: a common defence with older roofs. Difficult for the insurer to substantiate.
  • Actual cash value versus replacement value: with roof covering older than a certain age, insurers often want to apply actual cash value. The policy conditions determine whether that is correct.
  • Sub-limits for outbuildings, garden houses and ancillary buildings: often hidden in the policy, often relevant.

Guidance through to settlement

Until repair is complete and the final amount has been paid out. Including assessment of quotations, advice on repair versus replacement, and — where necessary — objection to unreasonable deductions.

Common points of dispute

  • “The storm did not meet the threshold”: the KNMI measurement must match location and timing. A local gust or whirlwind operates independently of the average.
  • “The tiles were already loose”: a statement that the insurer must substantiate, not one that you must refute.
  • Aesthetic versus functional match: a new tile on an old roof looks different. The question is whether that is legally acceptable within your policy.
  • Solar panels after hail: often still working now, failing within 1-2 years. That damage pattern is well known in the trade and can be substantiated.
  • Business interruption in the agricultural sector: crop loss, blown-over greenhouses, damage to stock — often more extensively covered than a first reading of the policy suggests.

What you can do

  1. 1 Take photographs and videos immediately — before any emergency repairs.
  2. 2 Note date, time and location; keep weather reports or news items from that day.
  3. 3 Carry out only those emergency repairs that are strictly necessary to prevent further damage.
  4. 4 Keep receipts for emergency repairs, roofers and equipment hire.
  5. 5 Engage your own counter-expert before accepting a quotation from a contractor proposed by the insurer.

Frequently asked

My insurer says 'the storm wasn't strong enough'. Is that correct?

That is a frequently heard defence. Many policies set the threshold at force 7 or 8 Beaufort. The question is then: was that wind force reached at the time and place of your damage? The KNMI measuring station may be ten kilometres away and a local gust can be much stronger. We retrieve all relevant measurements — KNMI hourly readings, neighbouring stations, any reported whirlwind sightings — and substantiate whether the policy condition is being applied correctly.

Hail: will my insurer cover it?

Many buildings and contents policies cover hail damage, but additional conditions often apply to specific categories — roofs, vehicles, crops, solar panels. With significant hail damage, court cases also frequently turn on the size of the hailstones, because some policies impose a minimum diameter. We examine both the policy conditions and the facts.

My roof has been repaired with new tiles that do not match. Is that allowed?

Insurers often opt for partial repair: only the dislodged tiles are replaced. Aesthetically this often results in a patchwork; functionally it can work. Whether this is acceptable depends on what your policy covers (replacement value or actual cash value, repair or replacement) and on what is reasonable within those parameters. We assess this for your situation.

How quickly can you be on site?

With storm damage to roof or façade, watertightness comes first — do not wait with emergency repairs if these are needed to prevent further damage. We usually attend within 24-48 hours. Call +31 30 662 2424.
