Why are the roofs of some houses blown off during a wind storm?

Expert Answer:

The high wind blowing over the roof creates a low pressure in accordance with Bernoulli's principle. The pressure below the roof is equal to the atmospheric pressure which is now larger than pressure above the roof. This difference of pressure causes an upward thrust and the roof is lifted up. Once the roof is lifted up, it is blown off with the wind along its direction.
