How do I see the ceilings?

You have to  move all walls up, then you can see the ceiling:

That works in build/buy and live mode

Same situation with all walls up.

Walls are up.  No ceilings.  I can be in a room and no ceilings.

Now I'm in the room.

Nothing works.  I wish it were as simple as putting the walls up.

Luxana49Once you had the walls up, did you hit tab to go into the camera mode?

I put the walls up and hit tab.  That brings on the free camera mode, but not the ceilings.  So frustrated!

You can go into first person mode, I'm not sure how but that might work but if you go into tab mode and PAGE UP the ceilings are visible as a builder I know this works in build mode but I'm not sure about live mode.

(Edit: walls up too)

It doesn't work for me in either build mode or live.  When I page up, I just get the open air or next floor.    I tried loading another game, different lot, same thing. There's a glitch in my game.  I'm getting a new laptop in a few days, so I will download the game, and maybe that will work.  If anyone has any other suggestions,  please post here.  Thank you!

Luxana49  All your screenshots seem to be from above looking down into the room. Are you zoomed in far enough that your camera would actually be inside the house when you tab into the free camera mode?

I know this is an old thread, but ceilings have been a long-standing complaint of mine. My complaint is that when using Tab to enter free camera mode, you are no longer in build mode and can't access any of the build mode tools. As a result, using the eyedropper to copy a ceiling's texture is impossible. 

To clarify for Luxana49​ however, ceilings cannot be viewed from above in any view mode. You need to move the camera below the ceiling level and look up to see them. Make sure your walls are up before using Tab to enter free camera mode, or use the Home key once or twice while in free camera mode to do the same. At that point, use the E and D keys on your keyboard (like "Elevate" and "Descend") to glide up or down through a ceiling. Once you are below the ceiling, you can look around using the mouse, including looking up at the ceiling.

If you elevate into an upper floor and it isn't visible, use the PageUp key a few times to display all upper floors. Just be aware that when you leave free camera mode, you will be left looking down from above the roof.
