Thanks. The idea is to throw water and see where it goes.
Insulation damage is insulation dmamage, water or wind.
I called the expert, who I respect a lot, and he basically offered to
look at it at his hourly rate. His expertise is probably worth more
than the equipment, but I have to compare that cost to the cost of
just adding a new layer of siding (with energy stimulus). And,worse
of all, I have a co-owner who is reluctant to do anything.

How is water going to tell you where the leaks are. It will just
disappear into the house, not show up on IR imaging?

If you want to experiment with it yourself, consider an appropriate infared
filter for your camera.

Photographic film and silicon image sensors do not respond to low
temperature thermal infrared. Usually over 99.98% of that is of
wavelengths longer than 3,000 namometers. Film that responds much past
1,000 nanometers is about as common as hairy eggs. Silicon image sensors
only go out to about 1100 nm, faintly to maybe 1300 nm.
