Ceiling should be there, did you try placing a ladder?
Did you change the view mode?
Think you need 3 clear tiles on the floor to place the ladder, might be 4 can't remember offhand, unless you stretch it wider after placing which will double the clear tiles needed.
I always use the "floating" ladder so it doesn't leave that boxed in blank space underneath!

I think i might have change something. I started a new game
Now even the room that come with the game i dont see the ceilling either. I tryed to switch between seeing the walls and not seeing them
but still no option make the ceilling aPPEAR. When i startes my first game last week i was seeing the ceillings on those room and now no. I dont know what i did but seems i made something to not make them appear anymore and i dont know what it is and even in a new game that dont work.
