Roof rack is possibly the best way to go - but it might restrict your ability to get into a lot of car parks - particularly in rural areas where they are trying to stop caravans staying overnight.
I have gone the towball route with a Thule rack which required no mods to the standard tow ball and I am very happy with it. There is a bonus that you can lift the whole rack off and leave it (padlocked to something) on the ground at your destination if you are away for a few days which saves finding somewhere to store bikes or dragging them with you every time you go to the pup/shop etc.
Have tried various rear door hung racks in the past and they were all a bit of PITA if you had more than one bike on them to prevent them rubbing against each other.
