My plan is to do roofing tar on the outside first, then caulk on the inside. That way the tar will prevent the caulk from going through. Any hole that seems too big to put goop alone, I will put a small piece of metal or plastic over the hole first, then goop! Some holes may not be accessible from below, in which case you just have to do the inside alone.
