How Does Hail Destroy Your Roof? Oh, Hail!
Hail forms when strong currents of rising air, known as updrafts, carry droplets of water high enough that they freeze. A strong updraft allows hailstones to grow large enough to reach the ground. Simply put, the stronger the updraft, the larger the hail.
Once they grow large enough to begin falling, they speed towards the Earth as fast as 90 mph, taking around a minute and a half to reach land! Small hailstones usually melt before reaching the ground, but the larger ones do hit the ground and can cause extensive damage.
Yikes! Can you imagine getting hit by a ball of ice at 90 MPH? Have you ever watched an MLB player get pelted with a 100 MPH fastball? Now imagine your roof taking 1000’s of “hits” just like that.
Most roofs in Middle Tennessee are made of asphalt shingles. These shingles are typically composed of a lightweight fiberglass mat impregnated with asphalt. Then, while the asphalt is still hot a layer of granite stones is applied. The asphalt is the water repellent aspect of the system, and the granite adds aesthetics with a layer of protection from the sun’s UV light. Shingles may seem simple, but they are a very complex system, carefully designed to protect your home from the elements.
When a roof suffers a hail “strike” the asphalt shingles may become damaged, and the issue is not always readily visible from simply looking from the sidewalk or from the front of your home. The force of the hail on the shingles may produce a bruise on the mat of the shingle. Oftentimes when enough force has impacted the shingle to produce a bruise, the granite stones are dislodged from the shingle. As time goes on, the granite stones fall off the shingles, exposing the bruised area to the sun’s UV rays. As a result, a year or two later – after the sun has the time it needs to destroy all the waterproofing elements of your shingles – your roof will start to leak.
