Hail damage can occur anywhere in the United States, damaging homes, vehicles, and even causing bodily harm. Over 73% of significant hailstorms are reported from March through June. (National Weather Service) The spring season is known for hailstorms which typically coincide with thunderstorms during changing weather. With hailstorms resulting in over $15 billion in damages a year, it is essential to understand how to identify and proactively mitigate damage. (Weather Underground)
Cause of Hailstorms
Hail is precipitation that forms into a stone-like structure. Hail stones form when raindrops are carried upward by thunderstorm updrafts into a frigid atmosphere and freeze. Hail falls when it becomes dense enough to overcome the force of the thunderstorm updraft and is pulled to the earth by gravity. The colder the atmospheric air, the larger the hail size, which can vary from the size of a pea to a grapefruit. The largest hailstone ever recorded touched down in Vivian, South Dakota. According to the national weather service, it was 8.0 inches in diameter, 18.625 inches in circumference, and weighed 1.9375 pounds.
The size of a hailstorm can range from 100,000 – 215,000 ft to an area 10 miles wide and 100 miles long. They typically only last a few minutes, but some have lasted anywhere from 15 to 30 minutes. The aftermath of a hailstorm usually leaves visible damage, as described below. (National Weather Service)
Signs of hail damage
As previously stated, hailstorm damage can be vast and impact every type of structure in its path. The direction of the storm path and the way hail falls will ultimately determine the location of damages. Some specific indications of hail damage are:
- Circular indentation on the roof surface that impales the shingle.
- Dents on your gutters, downspouts, or other aluminum and metal structures.
- Missing paint, dents, or splitting on siding, decks, or window sills
- Broken glass in doors or windows
Wind-driven hail causes harm to siding and gutters, versus hail falling downward, which results in more damage to the roof structure.
Preventative Measures
Even though hail damage is unpredictable and can't be avoided, the Forum Forensics team has provided ways to lessen the impact of hail damage below.
- Be sure to clear gutters and drainpipes of leaves and debris.
- Keep the roof in good repair.
- Be prepared for electrical outages.
- Maintain trees and keep limbs and shrubs trimmed away from home.
- Park vehicles under a cover or in the garage.
- Choose cement-based or composite siding.
- Use storm shutters
The preventative measures above can significantly reduce the cost of hail damage. In addition, it can avoid interruptions to the livelihood of the structure's occupants.
Long Term Affects of Hail Damage
Following a strong storm, it is important to identify any potential hail damage to prevent further deterioration. Hail can penetrate roof systems leading to leaks that result in water damage. Shingles are UV-resistant; however, a hail storm can damage the UV protectant layer. UV damage will then dry out shingles, making them less weather resistant and prone to leaks. Water intrusion can lead to structural problems, mold growth, electrical issues, and even wood decay.
