What's on the other side of the wall?  Could you vent through there?

Perhaps I'm naove, but I don't see how unfaced fiberglass batting is going
to trap moisture.  I'd probably install it anyway, and then if it did rot
out the roof, replace the roof with something more functional and properly
vented.
