Tis the season for hail and after recent storms throughout the midwest, home and business owners are contending with repairs to damaged property. However unless your roof is leaking or showing large, visible pock-marks, hail damage can be tricky to spot. So how do you know if your property has been affected? If you have an asphalt roof, one quick symptom to look out for: check your gutter rains and downspouts. Often times when hail damages an asphalt roof, granules from the shingles are lost upon impact and runoff into the gutter system. If you see evidence of this, damage may have occurred. But there are plenty of other factors involved too.
Certainly the size and density of the hail stones play a role in the determining damage. If your area experienced hail less than 1/2-inch in diameter, chances are there’s nothing to worry about. Marble or golf ball size hail should be cause for concern, especially in excessive amounts. Other factors such as wind direction, velocity of falling hail, roof pitch, and even roof temperature all play a role. You may find that the windward side of your house took a larger hit than the leeward side. Similarly, flat roofs tend to see more damage than roofs with a very steep pitch. And the same can be said of colder roofs being less forgiving than warmer roofs.
Finally, the material on your roof (asphalt, wood, metal, etc.), the classification of that material’s resistance to impact, and the age of the roof are also variables. Just because your neighbor experienced hail damage, doesn’t mean your roof was affected the same way. Your local roofing professional can definitely help you determine whether or not a claim should be submitted to your insurance company.
