How much does a roof survey cost in London?
A formal roof survey and written report is a paid service. The fee depends on the property, the roof areas to inspect, access and the purpose and scope of the report.
Send the postcode of the property being surveyed, its type and what you need to understand. Include any deadline or requirements from an insurer or building surveyor. We’ll discuss the inspection approach and confirm the scope and final fee before you decide to book.
No obligation to book. Requesting a survey quote does not reserve an inspection or commit you to paying for a survey.

The inspection approach depends on the property, access and conditions. The report should make the scope and any limitations clear; an inspection cannot establish every concealed part of a roof.
- Internal checks within the agreed scope and available access
- External inspection of the roof and visible details
- Drone imagery where the location and conditions allow
- Moisture readings used alongside visual observations
- Photographs documenting the observed roof condition and defects
- Written findings, repair priorities and recommendations for the next steps
Choose the roof survey that fits your enquiry
Pre-purchase roof surveys
Understand observed roof defects and potential repair liabilities before buying. Share any concerns raised in the building survey, the property’s postcode and your purchase deadline. You can enquire even if you currently live elsewhere.
Roof reports for insurance enquiries
Document the observed roof condition and defects with photographs and written findings. Send the insurer’s requirements before booking so we can discuss whether the scope is suitable. Acceptance and claim outcomes remain subject to the insurer.
Roof-condition surveys and repair priorities
Understand the condition of the roof and plan the next steps. Tell us about leaks, staining, deterioration or previous repairs you want assessed. Written findings can help you discuss maintenance, further investigation and proposed repairs.
For a block or managed property, identify the roof areas and who can arrange internal and external access. Freeholders and managing agents can also explore our commercial roofing service for subsequent work.
Tell us what you need the report for ↗How booking your roof survey works

- Agree the scope and fee. We discuss what can be inspected and confirm the fee, inspection availability and expected report turnaround before booking.
- Inspection and written report. The survey follows the agreed scope. The report sets out observed condition, photographs, findings, repair priorities, recommendations and inspection limitations.
Roof surveys across London
We take survey enquiries for houses, flats and managed buildings across London, including Highgate, Hampstead, Finchley, Barnet and Mayfair. Send the full property postcode so we can confirm arrangements and any access requirements for that location.
The report and any roofing quotation are separate
Avent also carries out roofing work. Any subsequent quotation is separate from the survey, and you are free to obtain other contractors’ prices.
If your immediate need is a price for a roof repair or replacement, ask for a free works quotation. If you need a documented assessment of condition, discuss the paid survey. Our repair or replacement guide can help you frame the questions.

Common questions about roof surveys
Answers to common questions about the next step.
Is a roof survey the same as a free roofing quotation?
No. A roof survey records condition with photographs, written findings and recommendations within an agreed scope. It is a paid service. A roofing quotation prices proposed work and is free. Avent also carries out roofing work; the survey does not commit you to using us for repairs.
Can I arrange a roof survey before buying a property?
Yes. Tell us the property’s postcode, concerns raised in any building survey and the purchase deadline. We discuss inspection access, scope, fee and availability before booking. The inspection can only cover the areas accessible within the agreed scope.
Will every survey include a drone flight?
Drone imagery is used where appropriate and where conditions, permissions and the location allow. We discuss the inspection approach and record limitations.
Do you check inside as well as outside?
Internal and external checks form part of the survey service. The exact areas inspected depend on the agreed scope and available access.
How soon will I receive the report?
Tell us about your deadline when you enquire. We will confirm availability and the expected report turnaround before booking.
Can the report be used for an insurance enquiry?
Tell us what your insurer has asked for before booking, so we can discuss the proposed scope. A report does not guarantee a particular insurance outcome.
