If the roof part is rubbing against the metal strip on the boot/trunk lid then your roof is over adjusted. I take it you mean the two metal tips of the rear roof section as mine are close, perhaps 3mm clearance.
You may wish to ask your dealer to adjust this to prevent more wear, it may also make noise and also wear through the paint on the roof causing oxidisation.
