House Repair community, I wanted to run my problem by you all and see what the community thinks. I purchased my home about two years back and when I did there was about a 3' straight crack in my living room ceiling. I had someone throw some mud and paint on it and needless to say it is back with a vengeance. The crack has slowly grown over the last two years to a total length of about 15' and is about 1/16 - 1/8" wide at points. What is interesting is that it is a series of straight lines and I belive it follows the hip and ridge lines of the roof (pictures linked to below). I welcome everyone's thoughts as to the cause and potential fixes
