Condensation above ceiling when you live in the attic?
I moved into a New York City two floor house. The “third” floor is really a conditioned, finished attic, which is now a master bedroom. The walls and ceiling in the attic are covered in painted sheetrock. I suspect that there is insulation behind all of the sheetrock, because in the slanted side rooms of the attic (where there is no sheetrock), which are like crawlspace storage rooms, I do see insulation with foil backing. So, hopefully the same exists above the ceiling sheetrock too.
Do I have to be concerned about the warm room air in the winter causing condensation as it hits the wood holding up the roof? (Obviously that is very much hidden from view.)
In the worst case scenario that there is no insulation, would the painted sheetrock ceiling act as a vapor barrier?
I appreciate any advice I can get.
