Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure
The left room in the image was made with the normal "Room Tool"
The one on the right was made by the "Custom Room tool"
This did fix it, however I do think there is a glitch here. If I click on the yellow border to build ceiling, it says "remove ceiling" first. So what I did to get a ceiling, I made a room with the custom room tool. Pressed "remove ceiling" and then added the ceiling.
The game thinks the ceiling is there, however it's not. This only happens with a penthouse and the custom room tool.
