Buildings with balcony extensions, roof gardens, penthouses usually have railings. The only way to get them to show (yes tagging for rendering to learn what and what does not work) in the below example was to add the height of the roof plus 1 meter (here 9) and a min_height of 8 which shows as the below.
Just telling the feature is on level 3 or layer 1 e.g. does not give a result either.
NB Have observed when not exact heights are given for building parts, pieces on a roof such as the service building in this sample wont show either, just a strangely shimmering roof outline level with the main building roof where the part is supposed to be.
edit: in a way this is related to location=roof which at the time of this report does not work (yet), per issue 88
