I AGREE WITH JIM. I SEE THEM IN MOST HOUSES WITH VAULTED AND COFERED CEILINGS THAT ARE GENERALLY AT THE EXTERIOR WALLS USEING THE ROOF RAFTERS AS THE SLOPED PORTION OF THE VAULTED CEILING.
THE CRACKS ARE USUALLY IN THE DRYWALL TAPE JOINTS.
I DO CHECK THE EXTERIOR WALLS/SOFITS FOR ANY MOVEMENT (GAPS IN THE FREIZE AND FASCIA BOARDS).
I WRITE THEM AS COSEMETIC IN MOST CASES.
