We also use Infra-red Thermography and moisture meter technology in addition to water testing to isolate rain leak sources.
For home owner education,view the video below where he will define Infrared and Thermography. It is also defined at the bottom of this page with definitions and a link.

This is a rather technical field. I will give you some definitions but to get a laymans idea of this technology, I suggest watching the video and the link at the bottom of the page otherwise this can turn into quite a study in physics and is not so necessary for understanding the use of what physicists have already created: an infra-red thermographer and what it does.
