To reduce the likelihood of such negative consequences, you need to make a vapor barrier of the ceiling. As a rule, a special film is used as a material for vapor barrier, attached below the roof insulation. Polyethylene films are aging quickly enough, which is why it is advisable to use them to arrange a vapor barrier of the ceiling.
