Yesterday, my husband and I were sitting out on our back patio and we noticed that the siding was bulging out. The bulge is about the size of a basketball, and when I pushed on it, there was no give...the whole area around it was solid too. It's located just under where the ceiling is, but looking inside, there's no cracking or water stains anywhere (upstairs or down).
It's pretty cold here, but not below freezing, and I can't even begin to think of what this might be. I want to get it checked out, but I don't know who/what service would be the best to call in this instance.
Any help is appreciated!
Thanks, Jodi
