Jerry,
I am surprised at your comment that "you should pull out your IR camera at every inspection". That flies in the face of doing a visual inspection. Even though I live in one of the wettest parts of the country, I rarely get clients asking for moisture intrusion inspections. My
inspection fees are already at the high end of the market and doubt that customers would pay an extra fee for a IR scan. In fact I only know of one inspector doing IR which I mentioned above.
I am on the outlook for leaks but only pull out my moisture meter to verify leaks. This is done to manage our liability as using advance tools could raise the bar and expose us to liability from latent issues. The tools only come out to verify a visual finding.
