18) Question: “Will an infrared scan indicated leaks?”

Answer: Infrared scanners show temperature differentials, not wood moisture contents or wood densities which are the real areas of concern. They are effective during the application of water in a testing scenario, but are highly suspect in static conditions. They do not show what plane the water travels. It is a properly constructed building which anticipates a barrier breach and properly discharges the water through the drainage plane. It is also possible for wood to be completely rotten yet completely dry and such a condition will not evidence itself on an infrared scan. My experience is that as a “magic wand” to wave at a house to see if it’s “OK”, I give it about a “2” on the 1-10 scale.
