How much wind can a brick house withstand?
Shelter from the Storm
In fact, the tests found that homes made with brick exceed the 34 mph impact resistance requirement for high velocity hurricane zones in the Florida building code.
For centuries, buildings constructed of brick have withstood the ravages of hurricanes, tornadoes, high winds, hail and punishing rain. When used in conjunction with modern building codes, brick homes can remain standing when others on the same block might be destroyed.
The extent of wall flexing will depend on the amount of mortar droppings wedged in the air cavity. Brick veneer walls, without engaging metal ties, are free standing and high wind loads can topple them (Fig. 4).
According to a report by FEMA, new wood-frame houses constructed according to building codes perform well structurally, in winds up to 150 mph, while a steel homes can withstand winds up to 170 mph.
It is the building material that architects and engineers increasingly turn to for homes meant to withstand extreme weather and hurricanes. ICF can stand up against winds over 200 miles per hour, and the additional insulation means the concrete cures even stronger than standard concrete forms.
Wind Speed Risks to Homes
If any shingles are already damaged or lifting, they may be torn off. Winds reaching 60 to 70 mph can uproot trees and cause significant roof damage. Tropical storm and hurricane-force winds that clock in above the 70 mph mark have the power to destroy roofs and topple power lines.
Fire and Weather Resistant
Even if you have a fire, brick walls will keep it mostly contained to one particular room or part of the house. Brick structures can also handle high-speed objects flying into them from high winds such as tornadoes or hurricanes much better than other materials.
Hurricane Winds 90 to 110 mph gusts 115 to 135 mph: Extremely dangerous winds will cause extensive damage and all mobile homes will be destroyed. Houses of poor to average construction will be severely damaged or destroyed.
brick veneer homes provide some protection compared to wood or aluminum cladding up to and including F2 tornados. However, once winds exceed 136 km/h (F3 storm) the protection you get from having a brick home is insignificant and can't be relied on.
Clay bricks are stronger than concrete and many other building materials. When combined in an interlocking pattern with other bricks and held together by a cement called mortar, bricks make sturdy structures that can survive for hundreds, if not thousands, of years with very little maintenance.
How long does it take for a brick to erode?
If water is trapped inside bricks or in cracks in the wall, freezing water can dislodge and even remove bricks, causing the need for repair or brick replacement. However, in comparison to the life expectancy of home components, bricks typically have a long shelflife of around one hundred years if maintained properly.
The most common cause is water damage. As water penetrates the masonry and weakens it through a cycle of freezing and thawing, it loosens the mortar around the brick and pushes the brick out. Structural stresses can also cause spalling, in much the same way that they cause cracking.
Winds in the 70 to 80 MPH range can cause serious structural roof damage on houses and secured outbuildings and mobile homes. Winds of 90 MPH or greater can totally destroy even secured mobile homes and buildings.
It is generally believed that tornadic wind speeds can be as high as 300 mph in the most violent tornadoes. Wind speeds that high can cause automobiles to become airborne, rip ordinary homes to shreds, and turn broken glass and other debris into lethal missiles.
Sustained winds are 120 mph to 156 mph. How would this affect you? Catastrophic damage will occur — severe damage to roofs, exterior walls; toppled trees, downed power poles, power outages, water shortage.
Knocking you down would take a wind of at least 70 mph. The terminal velocity, which is the wind speed (falling speed) where the force of the wind equals the force of gravity, for a person is about 120 mph — that would likely knock you down. Comments Off.
The average person is most certainly not heavy enough to stand up to a 100 mph wind. Even buildings crumble in winds of high speeds.
*In the western North Pacific, the term "super typhoon" is used for tropical cyclones with sustained winds exceeding 150 mph. Very dangerous winds will produce some damage: Well-constructed frame homes could have damage to roof, shingles, vinyl siding and gutters.
An average person could be moved by a 67 mph wind, and an average car can be moved by a 90 mph wind.
Round houses or properties with square structures reduce the wind pressure on any one side, while a 30-degree roof slope offers the best wind deflection. Hurricane-proof homes are often fitted with reinforced windows and impact glass to keep the property weathertight.
What can 130 mph winds do?
Category 4 (major) hurricane
Sustained winds are 130 mph to 156 mph. How would this affect you? Catastrophic damage will occur — severe damage to roofs, exterior walls, toppled trees, downed power poles, power outages, water shortages.
The shift away from structural brick began after World War II. Mid-century consumers wanted suburban homes that looked distinct from their urban counterparts and newer building codes no longer required brick. That, meant less demand for both the material and the masons needed to install it.
According to the International Association of Certified Home Inspectors (IACHI), brick structures are built to last 100 years or more.
If the connections between the roof and walls are weak, these wind forces will drive the roof and walls to give way. Once the roof blows off the entire structure can collapse within seconds. Flying debris shatters windows and pounds exterior walls. Winds blowing over the roof exert uplift, like an airplane.
- at 39 to 46 mph, branches and limbs can be broken from trees. Cars can also possibly veer on the road, especially high profile vehicles. - at 47 to 54 mph, there will be light structural damage. - at 55 to 63 mph, entire trees can be uprooted and considerable structural damage can occur.
High risk – 40 to 55 mph. This is the point where a “high wind watch” is issued by the National Weather Service. Even small branches can break, it is almost impossible to just walk outside, and roofing shingles may well be ripped off or broken off at their ends. Over 45 mph, property damage becomes extremely likely.
Brick houses can last at least 100 years with minimal maintenance. With regular care and attention, including mortar repointing, brick houses can last 500 years or more.

A brick home lasts longer than concrete and is more durable than wood. While wood has many benefits, it is not as reliable as using brick. Wood has a tendency of attracting different types of pests and may require treatment. Termites or other insects are not a threat to brick or concrete.
But generally even a brick house will not stand up to an F3/EF3 or stronger tornado. Virtually nothing can withstand and F5/EF5 tornado. The video linked below shows an F5 tornado (in this case small, but extremely intense) lifting a well-anchored brick house from its foundation and tearing it apart in midair.
How strong of a tornado can a brick house withstand?
It depends on the intensity of the tornado and how well-built the house is. Most brick houses could withstand a tornado as strong as EF2 and remain mostly intact. Around EF3 intensity, though even brick houses will be largely destroyed. If the house is hit by EF5 winds, it doesn't stand a chance.
Homes built with insulated concrete forms (ICF), like Fox Blocks, maintain their integrity during the high winds of a tornado. Insulating concrete forms can withstand winds of over 200 mph.

- Expense – Though durable, brick is more expensive than many other building materials, and a brick home may cost 6 to 7 percent more than one with vinyl siding.
- Deterioration – Porous brick can be vulnerable to mold in damp conditions, and It can also be damaged by plant growth, such as ivy.
