Storm Damage to Slate Roofs in Merseyside: What Insurance Covers

By Chris, owner of Everlast Roofing North West (20+ years on Merseyside roofs) · About Everlast Roofing · Last updated 2026-07-22

Merseyside does not get many named storms, but when the wind comes hard off the Irish Sea across Crosby, Formby and the Sefton coast, it finds every slate that has weathered loose and every lead flashing that was on its last legs. The morning after, my phone does not stop. Slipped slates, a stripped ridge, lead peeled back off a chimney, and a homeowner staring at a wet patch on the landing ceiling wondering who pays for it.

The honest answer is: often the insurer does, but only if the claim is handled properly. Storm damage to a slate roof is usually covered by buildings insurance. Wear and tear is not, and the two can look similar from the ground. What tips a borderline claim in your favour is evidence and the way a roofer documents it. Here is exactly what insurance covers, where the line sits, and how to make your claim pay.

What storm damage to a slate roof actually looks like in Merseyside

Storm damage on a Merseyside slate roof is rarely dramatic from the pavement. You are not usually looking at half the roof in the garden. It is more often a handful of slates slipped or missing after the wind has got under them, a ridge tile lifted or cracked, or a lead flashing around the chimney peeled back where the wind found an edge. The leak that follows shows up on the ceiling a day or two later, often several feet from the actual hole because water runs along the timber before it drops.

The most common storm faults I see across Liverpool and the Sefton coast are these:

• Slipped or missing slates, usually above a bay or along an exposed edge where the wind lifts them.
• Cracked or dislodged ridge tiles, where the mortar bed has weathered and the wind finished the job.
• Stripped or peeled lead flashing around chimneys and in valleys.
• Debris damage, where a neighbour’s aerial, a branch or a fence panel has come down on the roof.

The reason this matters for a claim is that all of these are sudden, identifiable events tied to a specific storm, which is exactly what buildings insurance is designed to cover. It is the difference between damage that happened on Tuesday night in a gale and damage that has been creeping on for five years, and telling those two apart is what the next section is about. If water is coming in now, the first call is for an emergency watertight repair to stop the damage while you sort the claim.

Does home insurance cover storm damage to a slate roof?

In most cases, yes. Buildings insurance policies cover storm damage as standard, and a slate roof stripped or slipped by high winds is a classic storm claim. The wrinkle is how insurers define a storm. Most use a threshold of sustained winds or gusts around 55 miles per hour, and many now cross-check your claim against Met Office data for your postcode on the date you give. So the date of the damage matters, and so does whether the weather that day genuinely qualifies.

The key word insurers use is sudden. Storm cover is for sudden, unexpected damage from a specific weather event. If a gale on a named night lifts slates off your roof, that is sudden and it is covered. If the same slates had been slipping for three winters and this storm was simply the last straw, the insurer may argue the underlying problem was wear and tear, and that they are only liable for what the storm itself did. This is where claims get contested, and where evidence earns its keep.

Two practical points. First, check your excess before you claim, because for a repair of a few hundred pounds it can be cheaper to pay for the work than to claim and lose your no-claims position. Second, do not authorise a full re-roof on the strength of one storm without reading the section below on betterment, because insurers rarely pay to replace a whole roof off a single event.

Wear and tear vs storm damage: the line insurers draw

Every buildings policy excludes wear and tear, and roofs are where that exclusion gets used most. The insurer’s position is simple: they cover sudden accidental and storm damage, not the gradual ageing of your roof. On a slate roof the classic wear-and-tear problem is nail sickness, where the iron nails holding the slates have rusted through over decades, so slates slip in ones and twos with no storm needed. That is not a claim, that is maintenance, and no honest roofer will tell you otherwise.

The trouble is that from the ground, a slate that slipped in a gale and a slate that slipped from nail sickness can look identical. The difference is in the detail: a storm-slipped slate is usually intact and the nail is often still sound, whereas a nail-sick slate comes away with a rusted stub and its neighbours are visibly on the move too. A roofer who knows what he is looking at can tell the two apart on the roof, and can photograph the evidence either way.

This is exactly why you want a roofer, not just a loss adjuster, looking at the roof. An honest roof inspection after a storm tells you plainly which faults are storm damage you can claim for and which are wear and tear you cannot. Mixing the two up is how claims get rejected, and how homeowners end up paying for a re-roof they were told insurance would cover.

How a roofer makes your claim pay: photos, evidence and an itemised quote

Insurers pay claims that are well evidenced and query claims that are not. The single most useful thing you can have is a set of dated photographs of the damage, taken as soon as it is safe, showing the slates, the flashing and anything that has come down. If you cannot get up safely, do not try, but photograph what you can from the ground and from a window, and photograph the debris on the lawn.

When we come out to a storm job, the roof gets photographed close up before anything is touched: the slipped slates, the stripped lead, the point of entry, the debris. That record goes to you, and it goes to the insurer with an itemised written quote that separates the storm repair from any unrelated wear and tear we happen to notice. Keeping those two things separate is important, because a quote that bundles storm damage and old wear and tear together gives the insurer a reason to question the lot. On a slate or lead job the detail matters, and our slate and tile repairs are documented exactly this way.

One more thing worth knowing: you do not have to use the roofer your insurer suggests. You are entitled to appoint your own, and provided the quote is fair and itemised, the insurer settles against it. Where the storm has also damaged gutters, fascias or soffits, we document and quote that roofline work in the same claim so nothing gets missed while the access is up.

What a slate roof storm repair costs in Merseyside (2026)

Even when you are claiming, it helps to know the numbers, because your excess and no-claims decision depends on them. These are typical 2026 costs for storm repairs on a Merseyside slate roof, before any insurance settlement.

Storm repair	Typical Merseyside cost (2026)
Replace a few slipped or missing slates	£180 to £400
Re-bed a lifted or cracked ridge	£200 to £500
Renew lead flashing to a chimney	£300 to £700
Re-slate a storm-stripped section	£600 to £1,500
Emergency watertight cover (same day)	From £120

Most single-storm slate repairs across Merseyside sit in the low hundreds, which is exactly why the excess matters. If your buildings excess is £250 and the repair is £300, claiming saves you fifty pounds and may cost you your no-claims discount, so paying for the work outright is often the smarter move. Where a claim really earns its keep is the bigger jobs: a storm that has stripped a whole section of slate or torn the lead off a chimney valley, where the bill runs into four figures.

Wherever the roof is, from the exposed coast at Crosby and Formby to the streets of inner Liverpool, the itemised quote you get should show the storm repair on its own, priced fairly, so you and the insurer are looking at the same numbers.

Can you claim for a whole new roof on house insurance?

This is the question everyone hopes has a yes attached, and usually it does not. Insurers work on a principle called indemnity, sometimes described as betterment: they put you back in the position you were in before the storm, they do not fund an upgrade. So if a storm damaged one section of an old slate roof, they pay to repair that section, not to replace the entire roof with a brand new one. Getting a whole new roof off a single storm claim is rare and generally only happens when the storm genuinely destroyed most of the covering.

There is a grey area worth understanding. On an older Merseyside slate roof, matching new slates to the original can be difficult, and sometimes a like-for-like repair genuinely requires more than a patch. A good roofer documents this honestly, because there is a real difference between a section that cannot be matched and a homeowner hoping to get the whole roof done on the insurer’s tab. Insurers know that difference too, and they scrutinise re-roof claims hard.

If your roof is genuinely at the end of its life and the storm was the final straw, the honest path is to accept the storm repair on the claim and plan a full re-roof as separate, planned work. Trying to force a re-roof through a storm claim usually ends in a rejected claim and a lot of wasted time. Straight, evidenced, and repair-first is the approach that actually gets homeowners paid.

• Photograph storm damage as soon as it is safe, and note the date and the weather.
• Storm damage to slate is usually covered; wear and tear such as nail sickness is not.
• Insurers often use a wind threshold around 55mph and cross-check Met Office data for your date.
• Get emergency watertight cover first to stop the damage, then handle the claim.
• Check your excess: for a repair of a few hundred pounds, paying outright can beat claiming.
• Use your own roofer, not just the insurer’s; a fair itemised quote is settled against.
• Do not expect a whole new roof off one storm; insurers pay to repair, not to upgrade.
