I have a 120sq ft shed/building that insulation and drywall was added flush (instead of flat ceiling) to the ceiling to maximize height inside (please see pictures for hopefully good description). I had an issue with few drops of water under the lights pictured when I took them off. First, I thought the roof was leaking but after running a hose on the roof with no leak, the only other thing I'm thinking it could be is condensation. This may have been an issue with the recent rain (from So Cal so doesn’t usually rain) so the difference between the cold ceiling and hot interior created it. I’ve gotten conflicting reports on what to do: One contractor told me I should vent the roof in some way. The other said a vent would expose the drywall/insulation to the elements and to just get a portable fan/heater so air/temperature could be regulated since it’s only 120sq ft. I like the fan/heater option since it's something I was going to buy anyway for hot/cold times, but maybe the right way is to vent it. What should I do?
