This attic has the ceiling insulated with Fiberglass with paper vapor retarder. There is rafter venting between the insulation and roof sheathing. The gable ends have fiberglass with plastic sheeting. The floor (2nd floor ceiling) does not appear to have any insulation (where visible).
The attic doesn’t have its own heating source and, I am assuming, seldomly used as it has pull down stairs (that’s another story) so it technically is not a conditioned space.
I did notice some staining from moisture (not currently wet) on the drywall for the 2nd floor ceiling at the Butt ends of the Batting on the West side of the roof. The staining was noted in atleast 3 bays at the same location of the Butt joints.
Outside of the paper being exposed issue, is the paper holding moisture ie: condensation and then flowing to the joints (I don’t believe there are any issues with the roof. Would it be correct to just install drywall and call it good? or better to remove the paper and leave for free movement of moisture?
As said before, there is rafter venting installed and from the outside there appears to be ridge venting, though could not be confirmed without removing some of the stapled in insulation. Shouldn’t the soffit and ridge venting help alleviate the moisture issue?
Thanks for input,
