Can someone please tell me what is going on in my house. Almost all he rooms are starting to form these raised bulges lines from wall to wall on the ceiling. They are raised and don't move when pushed on. I'm at a loss.
12-14-19 update So the raised lines on the ceiling only seem to be getting worse. Protruding more than before. Every ceiling on the first floor has them now. Second floor ceilings don't show any as far as I can tell. Not sure what is causing it. I had my roof replaced and some roof ventilation installed when we bought the house last year. Only seems to be getting worse as time goes on.
