Hail Storms and Hail Damage
Hail causes approximately $1 billion in damage annually in the United States to houses, buildings, cars and crops. The costliest hail storm in US history caused an estimated $2 billion in damage (Kansas City, April 2001)... and that's from one single storm.
Per NOAA, Small hail, up to about the size of a pea, can wipe out a field of ripening grain or tear a vegetable garden to shreds. Large hail, the size of a tennis ball or larger, can fall at speeds faster than 100 miles per hour and can batter rooftops, shatter windows and "total" automobiles.
Hail damage, like other types of storm damage, is classified as an "Act of God". As such, you cannot be singled out by your homeowners insurance company for a rate increase because you filed a claim. Insurance companies can increase premiums for everyone in an area that is susceptible to storm damage though, so use your insurance if you have hail damage. Learn more about storm damage insurance.
What is a Hail Storm?
Hail storms (also spelled hailstorms) are defined as thunderstorms that produce hail. Hail is a form of solid precipitation that is produced by thunderheads (aka thunderclouds; scientifically called cumulonimbus clouds). Hail stones are balls or clumps of ice that form in thunderheads due to the combination of sub-freezing temperatures and convection cell updrafting in the clouds.
How Hail Forms
Thunderhead clouds create strong updraft winds that cycle the precipitation up towards the top of the cloud, freezing and turning into hail along the way. In the top of thunderheads, where the updraft winds are weaker, gravity takes over and the hail stones start to fall. As hail stones fall back through the cloud, they pick up additional moisture from the cloud and grow in size. Hail stones can repeat this rising / falling action (called convection) many times. Once heavy enough to overcome the updraft winds, they fall all the way to the ground.
Interesting Hail Facts
Hail is defined as starting at a diameter of 0.2 inches or more. Hail can grow as big as golf balls, baseballs, and even soccer balls. Hail larger than 0.75 inches is considered large enough to cause serious damage in the United States. Per NOAA, hailstones can fall at speeds up to 120 mph.
The largest hailstone ever recorded in the United States was 8 inches in diameter, weighing nearly 2 pounds. This hailstone was recovered in Vivian, SD on July 23, 2010.
The previous largest hail stone ever recorded in the United States was 7 inches in diameter , almost as large as a soccer ball. This hail stone was recovered in Aurora, Nebraska on June 22, 2003.
Common Types of Hail Damage
Hail damage can be obvious or very difficult to detect, depending on the severity of damage and the thing damaged. If hail breaks through the windshield of your car and dents the roof, it's pretty easy to know you have damage. Other types of hail damage, like damage to homes, are not as easy to identify and require an experienced professional to adequately assess.

- Property Damage: Hail also causes damage to trees, plants and yards. Trees and tree branches can break and fall from the weight of hail and the winds that often accompany hail storms. When significant amounts of hail fall, then start melting on the ground, flooding and damage from standing water can occur. If you have substantial property damage from hail, you may want to contact a debris-removal service.

Hail Storm Safety and Preparation
Thunderstorms that produce hail can be very dangerous and must be taken seriously. Ever been hit by a golf ball or a baseball before? Now imagine a solid ball of ice falling at up to 120 mph from thousands of feet up in the air. Large hail falls with enough force to damage roofs, cars, break windows and more. If a person were to be directly hit with large hail, it could cause serious bodily injury, or death. It is imperative to seek shelter immediately when faced with hail storms, severe thunderstorm watches and severe thunderstorm warnings in order to protect yourself from falling hail.
Additionally, severe thunderstorms that produce hail can also produce tornadoes, violent winds and excessive rain. These conditions can also cause power outages and interruption to other public services. Pay attention to National Weather Service storm advisory warnings and take shelter indoors to stay safe in hail storms. If you are in your car when a hail storm hits, pull over to the side with your flashers on to reduce the chances of having an accident.
