Answer

See answer. The roofs are pushed off.

Work Step by Step

The air inside the house remains still with respect to the roof. However, the air outside the house is blowing past at very high speed. By Bernoulli’s principle, the faster-moving outside air has a lower pressure than the inside air. The pressure difference, acting across a large-surface -area roof, results in a considerable force that pushes up on the roof, and can even rip it off the house.
