Northern Illinois home built in 1905. Previous owner removed lather and plaster ceiling and replaced with drywall, with vapor barrier. Insulation is above vapor barrier in attic.
We noticed water stains on the ceiling, so crawling up there, I pealed back the insulation and found water under the water vapor, above the drywall.
I don't see any holes or rips in the barrier. It is close to an outside wall.
What do I do now?
