This Flower Mound property sustained hail damage to the roof, gazebo, and gutters. We installed GAF ArmorShield-II—a class-4 hail rated shingle—in Weathered Wood on the home and pavilion as well as replaced all gutters. Class 4 hail rated shingle also known as “impact resistant” are designed to withstand high winds and hail damage. For hail, the shingles are able to withstand a 2-inch steel ball dropped multiple times from a height of 20-feet. Select insurance providers may provide a discount to the homeowner for installing a Class 4 shingle!
