Small update of the "How to Inspect Moisture Intrusion" course

We did a small update of InterNACHI’s free online “How to Inspect Moisture Intrusion” course at, which is a section on caulks and sealants.

Thanks Ben.

Great add thanks

Figure 22 - “Brick Veneer Flashing at Roof” in the Inspecting for Moisture Intrusion course appears to show the head flashing over only 2 bricks which is usually less than 6". Closer to 4" actually. I believe head flashing must extend a minimum of 6" down the brick face and overlap the lower flashing not less than 4"

Okay. I’ll take a look.
