Here in Southern Indiana, many of us are not surprised by hail damage considering we are prone to hail in storms or in severe thunderstorms. We have already seen 3 or 4 storms with hail so far this spring and more than likely we will see some more before winter kicks in. There really is not a full way to protect your roof from hail but there are roofing materials that have a better resistance than others. Shingles have begun to be thicker to provide more resistance as well as other roofing systems most commonly found on commercial buildings. The best way to protect your home or business is by doing some research on roofing materials and on the Institute for Business and home Safety (IBHS) website.http://www.disastersafety.org
Often there are tests completed by IBHS to classify roofing material standards that they need to pass against many different conditions like hail and high winds. In the 1990s when IBHS began studying roof materials and weather conditions to see how they withstand. Now you see classes on roofing materials that show they have a good resistance. For the hail resistance there is a UL Standard 2218 with classes 1-4, four being the best resistance; this is commonly found on materials like shingles. They also did a classification 4470 for low slope or flat roofing materials like single-ply, Polymer-Modified Bitumen, built of roofs known as BURS and liquid applied roofs. They will either shower an approval code of 1-MH for hail or 1-SH for sever hail. To get more information on different roof materials and even more recent studies you can go to their website https://www.disastersafety.org/hail/protect-businesses-from-damage/. Some materials do not do so well in hail storms that especially can have 2 inch ice balls like metal roofs, you may not get a tear or breakage but there will be some denting.
