During a tornado or hurricane,when a high speed wind blows over a straw or tin roof ,it creates a low pressure in accordance with bernoulli's principle.However ,the pressure below the roof is still atmospheric. so due to this difference of pressure the roof is lifted up and is then blown off by the wind.

Did mesopotAMIA mud houses have roofs?
Yes, the mud houses in Mesopotamia did have roofs. The roofs were made from various materials depending on the period and location. Some of the materials used include: Reeds: Some roofs were made from reeds, sometimes with mud covering them. Planks of Palm Tree Wood: Roofs could also be made planks of palm tree wood which would be covered in reeds. The top of the roof would be connected to the house through brick. Thick Layers of Earth: In Assyria, the flat roofs were thick layers of earth on top of strong beams. This made the houses nearly or actually fireproof, and places of security. It’s also worth noting that these roofs were often flat, and people would sometimes cook and eat on the roof of the house during good weather. This got everyone up away from the streets, yet still out into the open air.

Do tornadoes cause damage because they cause homes and buildings to cave in?
Tornadoes can cause houses and other buildings to collapse, but most are not strong enough to do that. A typical tornado can tear away parts of roofs, break windows, and topple trees. Entire roofs and walls can go airborne in stronger tornadoes. Weak structures impacted by strong tornadoes often get blown away rather than collapsing. In very violent tornadoes the same thing can happen to well constructed houses.
Are they any pointed roofs in Malawi?

What type of damage can a tornado create?
Damage varies depending on how strong the tornado is. Weak tornadoes (EF0 and EF1) remove surface material from roofs, break windows, strip away siding and topple some weaker trees. Strong tornadoes (EF2 and EF3) remove roofs from many buildings or collapse walls, obliterate trailers, toss cars, and uproot many trees. Violent tornadoes (EF4 and EF5) level or blow away well built houses, strip the bark from trees, carry away large objects, and can even tear asphalt from roads.
