I have a storage room underneath my front porch (4 x 38) which is adjacent
to a full basement. The room is framed with cinderblock and the ceiling is
corrugated steel with the concrete porch cast on top of it.
I noticed today that there way water drops on the steel... I've never
noticed bofore, but have noticed that some boxes that were in there were
musty - which was a mystery because the walls and floor are bone dry.
I think it has to do with the cold weather outside & the warm basement
inside... anyone know how to solve the problem? Should I just glue some
sheets of insulation to the steel, or is something more involved necessary?
