Do buildings and homes cave in during a tornado?
Yes. Buildings and homes can collapse in a tornado. One common way this happens is the roof comes off, causing the walls to become unstable.

In an extremely powerful tornado such as a high EF4 or EF5 houses are blown away rather than collapse. Weak tornadoes usually do not cause significant structural damage.
