Short answer: A drone survey is the quickest, cheapest and safest way to see what condition a roof is in. A roofer on the roof is still needed when tiles have to be lifted, the underside checked or repairs done. For most people, the best order is drone first, roofer second.
How they compare
| Drone roof survey | Roofer or scaffold inspection | |
|---|---|---|
| Typical cost | From £75 with us; around £210 + VAT nationally | Around £260 + VAT for a roofer; £750+ if scaffold is needed |
| Time on site | Usually under an hour | From an hour to several days if scaffold goes up |
| Safety | No one leaves the ground | Someone works at height |
| Hard-to-reach areas | Chimney tops, valleys, steep and high roofs | Limited by ladder reach and safe access |
| Fragile or listed roofs | Nothing touches the roof | Walking on slates can cause damage |
| Under the tiles | Can’t see beneath the surface | Can lift tiles and check felt, battens and the loft |
| Small repairs on the spot | No | Yes |
| Something to keep and share | Photos and video of the whole roof | Depends on the roofer |
When a drone survey is the better choice
- You don’t know what’s wrong yet. Find the problem first, then pay a roofer only for the work that’s needed.
- The roof is steep, high or fragile. Three-storey houses, barn roofs, conservatories and old slate roofs are risky or expensive to access.
- You’re buying a property. Photos of the roof help you decide whether to renegotiate or get a specialist in.
- You’ve been quoted for big work. Seeing the roof yourself means you can judge the quote.
- You have several properties. Landlords can check a portfolio of roofs in one visit.
When you need someone on the roof
- The problem may be under the tiles, such as rotten battens or failed felt.
- The leak is coming from somewhere a drone can’t see, like inside the loft or under a flat roof membrane.
- You need repairs done, not just looked at.
- You need a formal building survey for a mortgage or purchase. That’s a job for a chartered surveyor, though drone photos can support it.
The approach most people take
Book a drone survey, look at the photos, and send them to two or three roofers. Many can quote from clear photos, which saves you paying for several call-outs. If the photos show the roof is fine, you’ve saved the cost of scaffolding altogether.

Common questions
Is a drone roof survey as good as a roofer inspecting it?
For seeing the condition of the outside of the roof, often yes, and it can reach places a ladder can’t. But a roofer can lift tiles, check the felt and battens underneath and look in the loft, which a drone can’t do.
Should I get a drone survey or a roofer first?
If you don’t know what the problem is, a drone survey first is usually the cheaper route. Many roofers can then quote from the photos without a separate visit.
