A cyclone has high speed winds followed by low pressure air region blowing.
Thus during a cyclone, the high speed winds over the roof tops, nothing much happens. But when the low pressure region comes above the loose roof top, due to pressure difference between inside and outside the roof, the roof top is blown away in air.
Tie two blown balloons to a rod so that there is some gap of 20 cm between the inner surfaces of the balloons. Now place your mouth in the center of the balloons and blow air between them. Initially the balloons go up horizontally in air and get separated a little more. But when you stop blowing, the region develops low pressure, as compared to the air on the other side of balloons. So the balloons come closer to about 10 cm or 15 cm.

Winds are caused by variations in air pressure. The wind blows from a region of high pressure to a region of low pressure. The speed of the wind mainly depends on the difference between the pressures of the air in the two regions. When air moves at high speeds, it creates a low-pressure area.
