I've seen two "issues" in which a drivethru or footpath travels underneath a overhang of a building. In my attempt to fix the issues, the closest solution I can find for either is to call it a "tunnel" but that doesn't seem right. Is there a preferred way to mark these (or should I just click "ignore" for the conflict/overlap issues)

Undercover Drive thru example:

I have no idea what renders which features as you desire, but I think what you're looking for is described on this wiki page. You might want to be aware of the open issues for openstreetmap-carto, the default layer at, that mention the building=roof tag though.

building=roof for that part of the building. If for some reason you don't want to change the outline, building:part=roof.

covered=yes for the way. tunnel=building_passage is for when there are walls on both sides.
