Did anyone see the recent Grand Designs program where a couple of
Lawyers in East London gutted a traditional terrace, and set about
turning it into an open plan space? (garden was nice, not so keen on the
house!)

What was the electronic probe device they used to detect the location of
the leaks on the flat roof? Any idea how it works?

You could ask them, but they would probably charge £200 to tell you
(plus disbursements and VAT)

It happens that John Rumm formulated :

I didn't see it, but my guess would be a simple damp meter. A small
instrument with a couple of fixed sharpened probes in the end, with
some sort of display?

An ordinary multi-meter with an high resistance Ohms range can used
similarly, if connected to a pair of fixed distance sharp tipped
probes. Any moisture in the material will show up as a decrease in
resistance reading.

Try typing "ultrasonic building leak detection" (without the
quotes) into Google, and there should be enough to satisfy your
curiosity.
