OT: Mold? on Ceiling in House
Off topic, I know, but there are a lot of smarts here so here goes. Our den ceiling is a cathedral style and it has a dark spot that has been developing at the peak for some years. We are in Beaumont, Texas so humidity is fairly high here and I don't think it is a roof leak. My wife believes this is "toxic mold" as this is a term she has heard. I don't know. The ceiling design probably prevents any attic inspection as there is only a foot or two of space between the ceiling and the roof there.
My question is, how can I determine what this is and what can be done about it. I tried spraying it with a bleach solution a few years ago, but that did not stop it.
Make it fit.
You can't win and there is a penalty for trying!
