Hey! thanks you guys!! I appreciate all the information! I live in privitized military housing. They are coming out on Monday to actually get into the attic crawlspace area to look at the roof. The second bedroom in my apartment smells musty all the time. When there is alot of moisture outside (Rain, snow…) the smell gets so bad, I have to keep the door closed to the bedroom. There is a spot in the bedroom that is doing the same thing as the other areas. It starts out with a little bit of the dark spots but you can see where the screws or whatever they used because there are orange rusty looking spots. In the other areas the spots turned black. I am looking into the ghosting because that is what they told me it was and even though I think they may be wrong in certain areas, I don’t want to stick with just one thing, even if I am in the wrong. Hopefully we can figure out what it is on Monday.
Again, thank you so much for all your information!!!
