As we know that whenever there is a storm passing over the roof it creates a low-pressure area over the top and there is pressure difference formation because there is high pressure beneath the roof because there is no wind flowing , so to maintain the balance the roof might be carried away by the wind due to the high pressure beneath the roof .

Some precautions to avoid flying off the roof are:-

1. Put heavy things on the roof.

2. The roof should be unbreakable.

3. The roof should be well fixed (screwed)

4. The roof must have some deep curves.

5. The roof must be flexible.
