Hail Damage

A hailstone is formed when a water droplet is frozen in a cumulonimbus cloud and is repeatedly tossed back up into the cloud by updrafts — each time acquiring another layer of ice. In this way, the formation of a hailstone is not unlike that of a pearl, excep that nature doesn’t hurl pearls from the heavens at 126 miles per hour. Given that hailstones can range from 0.2 inches to 6 inches in diameter, they can cause significant damage.

Roof damage can be caused by any hailstones bigger than 3/4-inches (marble-size). On asphalt roofs, these stones can cause damage as subtle as bruising (a fracturing of the base mat and resulting in softness of the shingle like an apple bruise) and as obvious as puncture holes. The most common form of hail damage to an asphalt shingle will be a crater or pock-mark, where the granules have been taken off or embedded into the underlying asphalt. Over time, the sun will bake the exposed asphaltic mixture, revealing the paper or fiberglass mat underneath and leaving a hole in the shingle.

Insurance companies have different standards for totaling an asphalt roof face for hail damage. The adjuster will mark off a 10 ft. by 10 ft. test square with chalk and circle all the hail hits he can find in that square. Some will be looking for 6-8 hits, while others demand as many as 12.

No roof is really impregnable to hail. Wood shake is a sturdy material, but can be split by 1-2 inch hail, or splintered by larger stones. When you start measuring hail in large fruits, nothing is really safe. Even concrete roof tiles can be cracked up the middle.
