Why does the roof blow away during a heavy storm?

During a heavy storm such as hurricane or tornado, when a high-speed wind blows over rooftops, it creates a low pressure (P) in accordance with Bernoulli’s principle.



However, the pressure below the roof is still atmospheric(=P.). So due to this difference in the air pressure, the roof is lifted up and is then blown off by the wind.
