Hope you can give us some advice. We're getting desperate. We bought this house in 2002. It has several 'cathedral' ceilings throughout with skylights in some areas. The problem we're having is resticted to the master bedroom. It's a master suite configuration with the bedroom and master bath together and a cathedral ceiling without an attic above it and no skylights.
For the first two years we owned the house, we had no problems at all. In the third year, we had a typical Colorado hail storm and had to have our roof replaced. Since that time there has been an awful smell in the bedroom that we can't locate and can't seem to cure. To me, it smells like mold or mildew. My husband says 'wet dog'. It's a very musty order. My husband and I both wake up in the morning with itchy eyes and stuffed heads. We've also noticed a large discoloration on the ceiling midway between the peak and the outside wall that looks like what you'd expect to see if someone smoked in bed for a long period. It's yellowish/brown and about three feet in diameter, but doesn't appear/feel damp.
We've had an inspector look in the visable attic. No mold or leaks that he could see. We've had all of the windows replaced and the surrounding walls looked at with no leaks or mold there. We had the area's treated, just in case. The contractor pulled up the carpet. No joy there. We had someone come out and do a meter reading (??) for mold and other airborne goodies. Also no joy.
We run a room air purifier and two fans continuously just to be able to stay in the room. It seems to get worse when the wind blows (I know that sounds weird) and the smell will also intensify if the windows are open on a breezy day.
If we have our typical cold Colorado winter with consistant temps that stay at freezing or below, the smell disappears. If we get above 40, it's back and is getting worse with each passing year.
We're about ready to have someone come out an rip the darned roof off! Any suggestions you may have would be deeply appreciated. Thanks so much!
