The After Effects of a Hail Storm on your Home

An intense thunderstorm can produce hail when both snow and rain are present, resulting in ice pellets that keep on increasing as long as the storm persists. Also, after they reach the bottom of the cloud, the updraft carries some of the hail back up to the storm cloud once again.

What happens during a storm

When the hail falls through the cloud once more, it acquires an additional layer of ice, and the pellets increase in size. During a hail storm, this cycle may be repeated several times, and when the updraft can no longer support the pellets, they fall from the cloud to the earth as ice. This happens because they fall too quickly to be affected by the warmer air under the thunderstorm.

Why hail can cause damage

Although the typical ice pellet does not exceed two inches in diameter, hail can very greatly in size and weight. In general it has the capacity to shatter windows, create the need for new roofing, and cause pockmarks in siding.

What homeowners can do

When their roof is in need of repair, they can choose covering that is impact-resistant. A product with this designation has met the standards of the UL2218 impact test and is rated in Class 1 through Class 4, which is the most resistant. This can be confirmed by the literature that accompanies the product and appropriate labeling on the package. (Note that local building codes or regulations may not provide adequate roofing protection.)

If you have been through a hailstorm, make sure to examine the trees, plants and shrubbery on your property to see the condition of your foliage. You should also determine if any aluminum roof vents, screens or patio covers have been dented. These signs of damage are an indication that your roof may be in need of repair as well.
