There are a few mechanisms. First, the wind going over the upward-pointing roof creates and upward force owing to Bernoulli's principle. The wind may also catch the roof under the eaves or cause a gable to fall inward and pick up the roof from below.

What kinds of damage can a tornado do to a bridge?
It depends on the type of bridge. Many bridges cave collapsed during strong tornadoes. Some have even been lifted and moved off their supports.
What is blow bye in engine?
Blow bye in an engine is typically the force that comes from the mufflers, commonly referenced to as the hot rod era in the 50s. The "Blow-Bye" refers to the young girls that would stand behind the muscle cars and as the cars took off, the blow from the muffler would lift their skirts.
When you turn off the switch of a blow dryer does that create a series circuit?
No, it opens the circuit so that no current flows.
What is the difference between extrusion blow molding and injection blow molding?
In injection blow molding starting parison is injection molded rather than extruded. In extrusion " " extrusion of parison occurs. There is three steps in injection blow molding: injection, parison and ejection. Tooling cost is higher in injection blow molding. one more, hot knife cut off the resins coming from heating zones before these goes to mold.

When does the tornado siren go off?
Tornado sirens go off when a tornado warning is issued and during their monthly test.
What can a tornado do to a house?
A tornado can cause significant damage to a house by ripping off roofs, collapsing walls, and shattering windows. The high winds and flying debris can also penetrate the structure, leading to further destruction.
How can a tornado affect a structure?
A tornado can damage a structure by generating strong winds that can break windows, tear off roofs, and collapse walls. The intense pressure differences within a tornado can also cause structural failure by pushing outward on walls or pulling upward on roofs. Flying debris carried by the tornado can further increase the damage to a structure.
What damage can an F1 tornado do?
An F1 tornado can cause moderate damage, including breaking branches off trees, damaging roofs, overturning mobile homes, and moving automobiles. While it is considered a weak tornado on the Enhanced Fujita scale, it can still be dangerous and pose a threat to people and property.
Why are houses made of wood in Saint Lucia?
It's because there are many tropical storms there so they might blow the roofs off.
How do tornadoes lift roofs off building using Bernoulli's principle?
Tornadoes lift roofs off buildings mainly through the combination of strong winds and pressure differences created by the swirling vortex of air. Bernoulli's principle plays a role by contributing to the lowering of pressure above the roof, creating lift force. This, along with the internal pressure of the building, can lead to the roof being lifted off during a tornado event.
What are roofing ties?
Most home roofs are not attached to the main part of a house. They use gravity and their weight to stay in place. However, if a storm with extremely high winds such as a tornado or hurricane happens, the roof can lift off and blow away. Roofing ties are used to attach the roof to the frame of the house to prevent this.
Are trailer homes safe to live in?
Trailer homes can be safe depending on how well you secure them. You would be better off finding a home that has a strong foundation, which makes it less likely to blow away during a tornado.
What is an EF2 tornado?
A tornado with estimated winds of 111-135 mph. Damage includes: Roofs torn off frame houses; mobile homes demolished; boxcars overturned; large trees snapped or uprooted; light-object missiles generated; cars lifted off ground.
What was the person name who was on top off a house during the hurricane in new Orleans?
there were many, many people on top of their roofs during "Katrina"
What is the wind speed of an EF1 tornado?
An EF1 tornado typically has wind speeds ranging from 86 to 110 mph (138 to 177 km/h). These tornadoes can cause moderate damage, such as stripping roofs off buildings and overturning mobile homes.
What effect can a tornado have on property?
A tornado can cause significant damage to property by uprooting trees, shattering windows, tearing off roofs, and even leveling entire structures. The strong winds associated with a tornado can also cause debris to become airborne, leading to additional damage. Overall, the impact of a tornado on property can be devastating.
