The short answer: buildings policies generally pay for damage from a sudden identifiable event and generally do not pay for a roof wearing out. A slate through the covering in a gale sits on one side of that line; twenty years of ultraviolet light sits on the other. Which side yours falls on is decided by evidence, which is why the photographs matter more than the phone call.
What separates an event from wear?
Timing and cause, and insurers look for both. An event has a date, a mechanism and a before-and-after: the roof was performing, something happened, it stopped. Wear has none of those. It is the slow arrival of a condition that was always coming, and no policy is written to fund maintenance somebody chose not to do.
The awkward truth is that most flat roof leaks are the second kind wearing the clothes of the first. Water appears suddenly indoors, so it feels like an event, but the covering had been failing quietly for seasons. An assessor who goes up and finds a surface at the end of its life will say so regardless of how abruptly the ceiling gave way.
That is not a reason to skip the claim. It is a reason to know what the roof looks like before you make one.
Why does a dated report change the conversation?
Because it moves the argument from opinion to record. Without one, two people who have never met the building disagree about what caused something neither of them saw. With one, there is a document written at the time by somebody who was standing on it.
Two documents do different work here. A condition report commissioned before anything happened establishes that the roof was being looked after, which is exactly the point disputed when wear is raised. A report written immediately after an event captures what failed while it is still there to photograph, which is the point disputed when cause is raised. The first is planning. The second is what storm damage work produces alongside the repair.
What should you gather before you call?
Assemble this first and the notification goes better, whatever the outcome. None of it requires anybody to go on the roof, and nobody should in bad weather.
- Photographs from the ground and from inside, dated, taken before anything is tidied or covered over. Wide shots that place the damage on the building, and close ones of what actually failed.
- The date and the weather. When it started, what was happening outside, and whether anything was reported locally. Specifics beat recollection three weeks later.
- Whatever history exists. Previous invoices, inspection records, the age of the covering if known, and any maintenance schedule. This is the part almost nobody has, and the part that carries the most weight.
- The policy itself, read rather than assumed. What it covers, the excess, and whether it requires notification within a period. That last one catches people out.
What happens when an assessor comes out?
On anything beyond a modest figure the insurer sends somebody, and it helps to know what that visit is for. They are not there to decide whether your roof is any good. They are there to establish whether what happened matches what the policy pays for, and their report goes back to the person who will make that decision.
So they look for the mechanism. Is there physical evidence of an impact, of uplift at an edge, of something that arrived and did damage? Does the pattern of failure match the weather on the date given? And, unavoidably, what state was the covering in beforehand, because a surface that had already lost its surfacing and split in three places tells its own story regardless of what happened on Tuesday.
None of that is hostile, and treating it as an interrogation makes it worse. The useful posture is to be the person with the paperwork. Photographs from the day, an idea of the covering's age, and any record of it being looked after are worth more than any amount of insisting. Where an assessor and a contractor disagree, they usually disagree about facts that could have been recorded and were not.
It is also worth knowing that a decision is not always the end of it. Insurers have complaints procedures, and beyond those the Financial Ombudsman Service exists for exactly this. Both of those are yours to pursue rather than ours, and neither is a route we can walk on your behalf.
One practical note that saves arguments later: if the assessor and your own contractor are going to look at the same roof, it is worth them looking at it together. Two visits a fortnight apart, one before a tarpaulin went on and one after, produce two descriptions of a roof that has changed in between, and reconciling those takes longer than arranging the diary would have done.
What can a roofing contractor do, and what can we not?
We can inspect, record and price. That means a written statement of what failed and what it appears to have failed from, photographs behind every line of it, the full extent including anything found beyond the obvious, and a scope with a figure against it, separated into what is known and what cannot be known until the covering is open.
What we cannot do is anything on the insurance side of the fence. We do not handle claims, we do not negotiate, we do not interpret policies, and nothing we write is a prediction of what any insurer will decide. That boundary is not modesty, it is competence: those are other people's professions and doing them badly would cost you more than it saved.
Where a claim does not go your way, the roof is still there and still leaking, and the useful next move is to price the work on its own merits rather than through a claim's lens. That is a repair or, where the covering has genuinely finished, a plan for renewal.
