Metal roofing is widely respected for its hail resistance. While there can certainly be storms from which no roofing material will escape unscathed, metal roofing offers good protection from leaks even if aesthetic damages do occur. The most widely-accepted test of hail-resistance is Underwriters Lab (U.L.) 2218, a steel-ball drop test that simulates the effect of hail impact on roofing products. Metal roofs pass U.L. 2218 at Class IV, the highest rating. As a result, homeowners in many hail-prone states can obtain discounts on their insurance premiums. Additionally, unlike other roofing materials, metal roofing resists hail damage even as it ages. This is another big advantage for metal.
Do you live in a hail prone area? In November of 2011, there were 2 hail storms reported in North Carolina (hail.org), with hail stones from 1″ to 1-3/4″ in size. Even today, near the end of February, there is hail predicted for southern states. This extreme weather can damage your roof.
