What Your Insurer Counts as "Lack of Maintenance" on a Roof Claim

The storm takes half a dozen slates off, you put in a claim, and three weeks later a letter tells you the damage was caused by wear and tear or a lack of maintenance rather than the weather. You know the roof was sound. The trouble is that you cannot prove what it looked like the week before, and the insurer has a surveyor's report, or sometimes just an aerial photograph, saying otherwise.

Two things are worth knowing before you argue. The burden is not on you: the Financial Ombudsman Service tells insurers plainly that "the onus is on the insurer to show that an exclusion applies in order to rely on it to decline a claim". And in practice the cases homeowners win are the ones with dated evidence of condition, gathered long before anything blew off. This guide covers what insurers mean by maintenance, what the ombudsman has found persuasive in recent roof decisions, and what a usable evidence file costs.

What "Lack of Maintenance" Actually Means in Your Policy

No home policy promises to keep a roof going forever. It covers sudden, identifiable events and carves out the slow decline that was always coming. The exclusion you are up against is usually two or three sentences long, and reading your own wording is the most useful ten minutes you can spend.

The Wording Your Insurer Is Relying On

Aviva's current home policy document (reference NHDHG15498 10.2025) states it as a condition rather than a buried exclusion: "One important policy condition is that you keep all the property you're insuring in good condition. Your policy doesn't cover loss or damage caused by wear and tear or a lack of maintenance." The consequence is graded, not absolute: "so if you haven't done this and this was the reason (or main reason) for the damage then we may not pay your claim or may not pay it in full."

NFU Mutual's Bespoke wording (BSKPLBK001, version 2.4.1 dated 29 September 2025) makes proportionate reduction the default mechanic: "Lack of maintenance. We'll reduce the amount we pay to reflect any wear and tear caused by a lack of maintenance." It also puts a causation gate on its own obligation, which is easy to miss and worth quoting back: if you fail to maintain the property, the insurer only declines "if you don't comply with these obligations and we can show that your non-compliance increased the risk of the claim or loss arising, or the severity of any claim or loss".

The clearest plain English definition of "maintained" we found in any current booklet is Homeprotect's, in its Florence policy document (version 1.2.1, published 2025): "Roofs: Must be reasonably maintained, with no significant wear, leaks, or missing tiles that could lead to further damage. Small signs of wear are expected, but missing tiles, rotting timbers or failing structural components, would not meet this standard." That concession, that small signs of wear are expected, is the sentence to hold on to.

Inspection Intervals, and Why Your Schedule Matters More Than the Booklet

There is a widespread belief that home policies require a roof inspection every so many years. For most mainstream wordings, that is simply not true. We read the Aviva and NFU Mutual documents above in full and neither sets any inspection interval at all, nor any flat roof clause. The duty is the general one: keep the property in a good state of repair.

A minority of wordings are stricter, and flat roofs are where it bites. Homeprotect covers "damage to or caused by flat roofs if the roof has been inspected and maintained by a Qualified Roofer within the last 10 years", defines a flat roof as one "with a pitch of 10 degrees or less", and then adds a sensible exception: "The requirement for a 10-year inspection and maintenance does not apply if the damage would have occurred regardless of maintenance." An AXA wording quoted in a 2024 ombudsman decision carried the same ten year flat roof requirement, with no cover at all "for any claim, regardless of cause" without proof of it.

Individual underwriting can go further still. In one ombudsman case the policyholder had his roof inspected every year for a decade because, as the decision records, "it was a requirement for his insurance". So the booklet is not the whole answer. Read your schedule and any endorsements, because that is where a condition specific to your roof will sit.

What Actually Persuaded the Ombudsman

Published ombudsman decisions are the most useful evidence available of how these disputes really turn out, because each one sets out what both sides filed and why one of them won. The pattern across recent roof cases is consistent, and it is not about receipts. It is about dated reports on condition, written by someone who got close to the roof.

The File That Won

In DRN-5803434, Mr P's felt flat roof lifted in a January 2025 storm and blew onto a neighbouring roof. LV's assessor reported rot, mould and salting, and said the storm had highlighted an existing problem rather than caused it. The ombudsman, Geraldine Newbold, upheld the complaint, and the reasoning is worth reading closely:

"Mr P's builder's comments are persuasive. I note the assessor didn't inspect the roof despite the opportunity to check under the tarpaulin for evidence of causation. And I note that Mr P arranged for the roof to be inspected for the previous ten years as it was a requirement for his insurance. He has provided reports for the past four years which state the roof was in good condition, including 'no water pooling' from the year before."

LV was told to reimburse the repair costs, pay 8% simple interest a year from the date Mr P paid, and pay £500 for distress and inconvenience. Three things did the work: the reports were dated, they described condition rather than merely recording that work had been done, and the insurer's own expert had not physically inspected the roof when he could have.

The Gaps That Lost

The losses are more instructive. In DRN-6121614, Storm Éowyn hit on 24 January 2025 with recorded gusts over 80mph, and the ombudsman accepted both that storm conditions occurred and that the damage looked like storm damage. The claim still failed, because of an answer on the insurer's own claim validation form: "Was the roof inspected/maintained by a qualified roofer in the last 10 years? No". A 2021 survey taken when the homeowner bought the property had already flagged several chipped, broken and slipped slates, and the decision notes: "No evidence has been provided that the above issues were investigated further or rectified between 2021 and the storm event."

In DRN-6118344, a felt flat roof failed in Storm Darragh. The ombudsman named the absence of a pre-loss record as the reason: "I also haven't been presented with any persuasive evidence, such as a homebuyer's survey that might shed light on the condition of the flat roof, pre-loss." The insurer's surveyor had put it even more bluntly: "As the flat roof covering has been replaced, the pre-loss condition cannot be determined." Moss worked against the homeowner twice over, once as a 2022 online image used as a baseline and once as visible growth on the failed felt.

DRN-5599962 is the case to read if you want the honest version. The homeowner had a close quarters roofer inspection three years before the loss, his own surveyor's report afterwards and photographs taken immediately. He still lost. Aviva argued the earlier report "doesn't suggest the roof was in good condition" and "merely determined the roof did not yet require replacement", and the maintenance done had not covered the edging strip adhesive, which was the point that failed. So record condition rather than work, and make sure the record covers the components that actually give way.

One caution. The evidence file only earns its keep at the third question. In DRN-5121958 the homeowner produced a roofer's summary and screenshots of £21,000 in payments and still lost, because recorded wind of 46mph fell short of the policy's 55mph threshold. No paperwork rescues a claim that fails on the weather.

Regional Price Differences

Roof survey fees are reasonably consistent across the UK, because the work is a day or less and the report is the deliverable. Access is what moves the price. A terraced house inspected from a ladder and a camera pole sits at the bottom of the £150 to £400 range, while a three storey townhouse or a steep slate roof needing a tower or scaffold can add £640 to £1,200 to the same job.

Gutter clearing shows the clearest regional spread. Checkatrade's figures, updated October 2026, put the average job at £103 in the North West and £169 in Greater London. The work is usually priced per job rather than per metre, so property height matters more than postcode on anything larger than a semi.

It is worth setting those numbers against what is at stake. The Financial Conduct Authority's value measures data for 2025, published 21 July 2026, puts the average buildings only claims payout at £9,036.84, with an acceptance rate of 62.44%, the lowest of the three home insurance categories. The FCA attaches its own caution to that acceptance figure, noting "inconsistencies in how firms report claims acceptance data for home insurance", so treat it as indicative. The ABI's figures for April to June 2026, published 3 August 2026, put the average claim for flooding, storms and burst pipes at £8,548, up 12% on the year. A documented roof costs somewhere between £150 and £550 a year to keep current. The comparison makes itself.

Frequently Asked Questions

Does my insurer have to prove the roof was badly maintained, or do I have to prove it was fine?

The insurer does. The Financial Ombudsman Service tells firms that "the onus is on the insurer to show that an exclusion applies in order to rely on it to decline a claim", and warns against relying on aerial imagery: "Sometimes we see reports where the roof hasn't been inspected properly and the insurer has relied on an aerial photo. Unless the photo clearly shows deterioration, and this is explained in the report, then we may not be persuaded that you've shown the exclusion fairly applies." Your evidence file is not there to discharge a burden. It is there to defeat the insurer's proof.

How often should my roof be inspected?

There is no UK standard interval, and that surprises people. Neither the NFRC nor RICS sets a frequency. The widely quoted "twice a year" traces to a Historic England maintenance checklist published in 2013, aimed at historic and older buildings, which advises inspecting pitched and flat roofs twice a year and after storms or high winds. In practice an annual or two yearly written inspection, plus a look after any serious storm, gives you a dated record cheaply. Check your schedule first in case a specific condition applies.

Will photographs from the ground or a drone survey be enough?

They help, and they beat nothing, but they are weaker than a close inspection. Across the decisions we read, the consistent winner is a report by someone who physically got onto or very near the roof, and the consistent loser is a conclusion drawn from a distant image. The ombudsman's guidance says it directly: "Clear and detailed reports to explain the expert's thinking, supported by photos of the damage, tend to be the most persuasive evidence."

Does a maintenance record guarantee my claim will be paid?

No, and anyone telling you otherwise is overselling. A claim must first clear the weather test and the question of whether the damage looks like storm damage at all. Beyond that, a record saying a roof "does not need replacing yet" has been read as evidence the roof was not in good condition, and maintenance to one part of a roof does not help when a different component fails. What a dated condition report does is remove the insurer's easiest argument, which is that nobody knows what the roof looked like before.
