We have received many calls over the years and here is one example:
Caller: I have what looks like mold growing where the ceiling and outside walls meet in my home.
Inspector: Have you made any recent changes within the home?
Caller: Not really, oh I did look into my attic one day and found it to be somewhat breezy with air flowing in different directions.
Inspector: So what did you do?
Caller: I went into the attic and blocked all the air coming into the attic from the soffit.
Inspector: Well sir, the problem was created when you stopped the air movement from the soffit into the attic, causing moisture to form and the trapped moisture has likely caused the mold to form.
The objective is that we must try to achieve the same temperature in the attic that is present at the exterior of the home. The greater the contrast in temperature, the more likely it is that moisture can form in the attic causing mold.
I've come across a lot of interesting tidbits of information during my 29 year career as a home inspector. I've been told that I'm pretty meticulous and a good 'teacher', so hopefully you'll find some interesting information here..
