don't they usually have a gap for moisture/condensation to escape?

if you spray foam the rafters they are encapsulated in foam.

Not in any situation I know of. 3 sides are in foam, the 4th is attached to plywood and the other side of that is the outside. That is enough to let water out. It is slow, but we don't need it to be fast.
