If you are buying a house, you have a survey. But not on the
roof/chimney stack?

That's likely to be the most costly thing to repair.

It occurs to me that if I buy a drone with a video camera, not that much
money, I could do a video survey of the roof/chimney stack for not too
much. Easy money & I get to play with a drone!

Not done much research, just an idea. Any thoughts?

The downside I can think of is if you're offering to do the survey, that
will incur a liability should the survey prove defective.

That's what professional indemnity insurance is for.

We have experimented with a drone for the inspection of aerials and
dishes that are on roofs where access would be expensive, needing
machinery or scaffolding. It's all right I suppose, but there are
limitations. You can't test the security of things by getting hold and
wobbling them, you can't really see small details like cable damage, and
there's always the risk that you might have to pay for the access
equipment just to get the drone back.

I don't think you'd be able to see whether flashing was intact or
whether ridge tiles were insecure.
