Ugh I can't decide what to do. I got on the roof today and found a half inch hair line crack in the plastic skylight near the caulking. A couple other questionable spots in the caulking look iffy. Makes me wonder if I missed in the fall or they detiorated. Anyways I know I can get a new skylight, cover everything with eternabond or just go buy a tube of dicor. I'm thinking the easy way cause I'm gonna take some time off of work to do it since will be warm and no rain.
The good news also is I took inside cover off and water seemed to go straight down crack and put screw holes. Very little moisture in ceiling. I put a fan in bathroom and will let run for few days.
Thanks for the input all.
