Atmospheric Events in Home Insurance

You've had two days of Poniente winds battering the Costa del Sol. On the third morning you wake up to a broken roof tile, a ripped-off shutter and damp stains spreading across the lounge. You call your insurer, confident that the atmospheric events guarantee — the one designed to cover precisely this — will sort everything out. And then the interrogation begins: "What speed was the wind blowing? Is there official data from the weather station?"

That question is no coincidence. It's the small print of this guarantee, and it's exactly what we're going to explain today.

What does the atmospheric events guarantee actually cover?

This guarantee is designed to compensate you when a weather event — wind, heavy rain, hail, snow, flooding — damages your home or its contents. The idea is straightforward: nature does something extraordinary, and your policy covers you. The problem lies in how "extraordinary" is defined.

In the majority of policy wordings we work with, the cover requires the event to exceed certain minimum thresholds: typically rainfall above 40 litres per square metre per hour, or wind gusts exceeding 80 km/h. And those figures must be certified by an official body, such as AEMET (Spain's State Meteorological Agency).

If that record doesn't exist or falls short of the threshold, some policies offer an alternative route: demonstrating that other well-maintained properties within a nearby radius suffered damage from the same event. But the burden of proof falls on you, not the insurer.

What do people think is covered that may not actually be?

The most common misconception is assuming that any leak or water ingress following a heavy downpour is automatically covered under this guarantee. In most cases, it isn't.

Under many policies, what the atmospheric events guarantee covers are the consequences of the water ingress — the ceiling stain, the buckled parquet floor, the damaged furniture — but not the repair of the underlying cause: the broken tile, the deteriorated sealant, the failed waterproofing membrane. That typically falls outside the cover and is your responsibility.

There are further nuances worth knowing:

• Frost and ice are a common source of misunderstanding. Under some policies they are not included in the basic guarantee and require a specific extension to be purchased, sometimes with a monetary cap and restricted to properties below a certain age. Under others, they are excluded altogether. Check your policy wording before assuming they are covered.
• Outdoor furniture — sun loungers, parasols, large plant pots, terrace furniture — is usually excluded even if protected by covers or awnings. This is one of the points that surprises clients in Marbella most, where outdoor living is part of everyday life.
• Cracks and partial structural damage are also generally not covered. Some policies only activate this guarantee in the event of total structural collapse, subject to an official declaration by the relevant authority. A serious crack caused by building works next door, however severe, may not be sufficient to trigger it.
• Bundled guarantees can also catch you out: some policies group atmospheric damage, vehicle impact damage and acts of vandalism into a single section with one shared limit. If you make a claim of one type, the remaining limit may be lower than you expected.

When does the guarantee apply, and when does it not?

It applies when the event exceeds the thresholds set out in your policy and there is official data to certify it — or alternative evidence of widespread damage in the area — and the damage affects elements covered within the property or its structure.

Examples where it typically applies:

• A cloudburst exceeding 40 l/m²/h brings down part of the garden boundary wall and causes flooding in the garage.
• A wind gust above 80 km/h tears off the roof of the storage room and damages the bedroom ceiling.
• Hail shatters the skylights and water enters, ruining the lounge floor and furniture.

Examples where it may not apply:

• There is heavy rain but the wind does not exceed the threshold and AEMET does not record the event as an abnormal weather phenomenon.
• A leak has been developing for months and the rain simply triggers it: the cause is not the weather event, but deferred maintenance.
• The damage is in the garden or on an uncovered terrace, affecting outdoor furniture or fittings.
• There are cracks in the façade but no official declaration of structural collapse has been issued.

How do policies differ?

This is one of the guarantees that varies most from one policy to another. Some policies cover leaks and water ingress up to 100% of the insured sum, with no caps or building age restrictions. Others impose specific monetary limits — ranging from a few thousand pounds to the full insured sum, depending on the policy — and also require the property to be below a certain age for the cover to apply.

Some policies also have different levels of cover — basic, intermediate and comprehensive, under various names depending on the insurer — and the actual scope depends on which level you have taken out. You cannot determine this simply by looking at the name of the guarantee: you need to read your particular conditions, the personalised document that sets out exactly which level you have purchased and what limits apply in your specific case.

The radius accepted for alternative damage evidence also varies: some policies accept proof of damage to properties within 500 metres; others extend that radius to several kilometres. This is not a minor detail if you live in an area where weather monitoring stations are far away.

What should you check in your policy before the first storm arrives?

• Rainfall and wind thresholds: what are the precise figures that trigger the guarantee under your policy?
• Alternative certification: if there is no official data, what radius and conditions does your policy require to evidence widespread damage?
• Cover for leaks and water ingress: does it cover only the consequences or also the repair of the cause? Is there a monetary cap? Is there a building age restriction?
• Frost and ice: are they included in the basic guarantee or do they require an additional extension?
• Outdoor elements: what happens with terrace or garden furniture? Is it excluded even if protected by covers?
• Level of cover taken out: if your policy has several levels, which one appears in your particular conditions?
• Bundled guarantees: do atmospheric events share a limit with other guarantees such as vehicle impact or vandalism?
• Excess: is there an excess — an amount you pay before the insurance kicks in — applicable to this guarantee?

If you are unsure what level of cover you have for storms, heavy rain or high winds, now is the time to find out. In Marbella, Poniente episodes and autumn rainfall can be more intense than they appear, and once the damage is done there is no time to discover that your cover was not what you believed it to be.
