Inspection or survey
What is the difference between a roof inspection and a roof survey?
The words overlap, so judge by what you receive. Below: how the two compare, what to ask for, and when a fuller survey is worth paying for.
The short answer
A roof inspection is a check of the roof's condition, and a roof survey is a fuller written report on it, but the two words overlap and no single definition governs them. Judge any quote by what you will receive: the checks made, the photographs, the written findings and any limits. The title on the invoice matters far less than that.

How the two compare
Firms use the terms loosely, so the table sets out how we use them. Another firm's survey may cover less or more.
| Point | Inspection | Survey |
|---|---|---|
| Question answered | What shape is the roof in? | What does it need, and why? |
| Checks | Ladder and loft | Ladder, loft and drone where needed |
| Findings | Faults and a verdict on each | Findings, causes and what repairs involve |
| Used for | An owner's decision | A buyer, lender, insurer or council |
Both end in photographs and written findings, and neither changes anything on the roof itself. The difference is depth, and how far someone else will rely on the result. If a quote does not say which checks it includes, ask.
The reader changes the wording as well. A report that goes with a Building Regulations application is read by the council's building control team or by a registered building control approver, while one for a buyer is read by a solicitor and a lender. If you are unsure who will read yours, say so before the visit, not after it.
What to ask for before you book
Because the words are loose, ask a few plain questions instead of relying on the name.
- Will someone go up to the roof itself, or will it be judged from the ground alone?
- Will the loft be included? Rafters and the covering's underside can only be viewed from up there, so a visit that skips the hatch misses half the roof.
- Will I receive close photographs of each fault, together with written findings and a verdict on each?
- Will the report say what could not be seen?
- Who will read it besides me, and does it need to suit them?
A survey that is meant for a mortgage lender or an insurer needs to be worded for that reader, so say who the reader is when you book. An inspection for your own decision can be shorter and more direct, with the verdict on each fault placed first.
On the same visit we can give you both, where the roof needs it. Our roof condition report answer explains the written part, and the roof inspections hub covers how a visit runs.
When a survey is worth paying for
For a roof you simply want checked, an inspection answers the question. A fuller survey earns its cost when someone else has to rely on the findings:
- a house purchase, where a buyer needs the roof described before exchange; our post on roof inspections before buying a house goes through it
- an insurance claim, where the Financial Ombudsman Service says the insurer normally has a surveyor write a report, and must prove any exclusion it relies on, with an inspection report for instance
- a listed building, where the council will want the materials described
- a roof you plan to re-cover, where the findings feed the specification
If you are unsure which applies, the order is simple. Decide who will read the findings, book the level of detail that reader needs, and keep the photographs and receipts together in one folder so that nothing has to be rebuilt later.
On MyJobQuote the average roof survey comes in at around £300 (its page, 12 October 2026). That is a national average and not our price; our roof inspection cost guide explains what moves it.
What comes after either one
Neither document is a quote. If the findings call for work, we price it afterwards as one written total price, and the survey is where that price starts. Where a repair is sound, the verdict is repair first; a re-roof only follows when it is the fair answer for the roof, and the findings explain why in plain words you can check against the photographs.
File the report alongside your other records for the house. Dated photographs give the next inspector a baseline, so new pictures can be set against old ones. A future buyer may also ask to see the report.
If the findings lead to a re-cover, building regulations may come into it. Approval is triggered when a new covering is 15 per cent or more heavier, according to the Planning Portal, and the survey is where weight is first asked about. Building control can say whether a given job needs an application.
Some roofs need more than a visual look. A roof covered in spray foam cannot be seen fully from the loft, and the RICS guide says the timber structure in that case cannot be fully seen or inspected. A report on such a roof should say that plainly. Where hidden damp is suspected, our thermal imaging survey answer shows what an extra tool can add.
More questions
Is a survey always more thorough than an inspection?
Not by name alone. One firm's inspection may cover the ladder, the loft and a full photographic record, while another's survey may be a short note from the ground. Compare what each quote lists: the checks, the photographs, the written findings and the stated limits. Those tell you how much you are paying for.
Do I need both an inspection and a survey?
Not necessarily. One visit with a written report can serve both, as long as the report is worded for whoever will read it. Tell the firm at booking if a lender, insurer or council needs the findings, so it can word them to fit, and you are not paying for the same visit twice.
