Hello,

I’m trying to build a barn, and after putting the wooden walls I’ve been able to build “roof over dirt floor” in the middle of the room, but no roof construction is available over the walls, who already come with a “wooden roof” over them”. The mixing of shingle roof in the middle and wooden roof around it look really ugly ☹

If I try to build just “roof” instead of “roof over dirt floor”, it builds a wooden floor + treated wooden roof (from my position, 2 down 1 west), and it’s not available over the walls either.

Does anyone know how to get a consistent roof of the same material?
