Hail: Roof - Choosing the Right Covering

Material provided by Federal Alliance for Safe Homes http://www.flash.org/

The roof covering form one of your home's critical shields of protection from hail. The most effective way to minimize hail damage is to use roofing materials that are resistant to hail impact. Even though most of the common roofing systems used today can be altered or modified for increased impact resistance, the features that make a roofing product impact resistant vary depending upon its material type. 

To reduce the potential damage to your roof covering, FLASH recommends that roof coverings has a rating of Class 3 or 4 when tested in accordance with UL 2218 or FM4473 for impact resistance. Use roof slopes of 6:12 (27 degrees) and greater. Particularly for new construction, the use of higher roof slopes (6:12 and greater) greatly enhances roof-system resistance to impacts from hail.
