Understanding the Effects of Hail Damage
An asphalt shingle is composed of a base, known as a mat. The mat, which is typically a fiberglass composition, is coated with asphalt and layered with granules. Asphalt shingles are expected to age with exposure to water and sunlight; and over time, sunlight deteriorates the underlying asphalt. Because of this natural aging process, most shingles carry limited warranties.
When hailstones strike a roof that is midway or further into its life expectancy, the aging process speeds up. Hailstones hitting an asphalt shingle will cause the granular surface materials to loosen, or get knocked off. This type of granule loss prematurely exposes the asphalt base to the sunlight, triggering a more rapid deterioration of the roof. When a shingle deteriorates, it tends to lose its ability to shed water off the roof. Water saturation begins and leaks occur as a result.
What is Hail?
Hail is icy rain that often accompanies tornadoes or severe storms here in the Jacksonville area. The lumps of ice can range in size from as small as a pea to up to six inches and weigh more than a pound. Hail can damage not only roofs, but cars, crops, and even airplanes.
Below is a brief video explaining what to look for if you suspect you have hail damage.
