I knew someone who got some used fancy oilfield devices and imaged
houses to find leaks using not only infrared but some pretty fancy

much in the decade since.

I have some siding, poynting and roof leaks, whose repair would be a
lot less costly if I could get a cheap imaging analysis.

I don't see how you expect IR devices to find roof leaks on your
house. IR devices are commonly used to find areas of poor thermal
insulation.
