Hail Resistant Roofing
March 5, 2018
Severe hailstorms damage and destroy non-hail resistant roofing materials. This occurs at great
expense and aggravation to property owners and insurance companies.
Typical Roofing vs Hail Resistant Roofing
Property owners in hail prone areas have done careful research to find hail-
resistant roofing, and local insurance companies are rewarding property owners who choose hail resistant roofing with premium discounts. Underwriters Laboratory has developed the UL 2218 test to measure the Impact Resistance of various roofing materials. This four-stage test calls for a 2” steel ball to be dropped onto the roofing sample from a height of 20 feet at its most severe stage. In order to pass the test, the roofing cannot
crack or rupture. This test is performed on new roofing materials and does not take into
consideration that some products become more brittle and less resistant to impact as they
How Kassel and Irons is a Hail Resistant Roofing Material
Many metal roof systems, including those produced by Kassel and Irons, have passed
the UL2218 standard at its most severe level — Class IV. Because metal, cannot lose impact resistance as it ages, homeowners who choose it are ensured of hail resistance for the life of their roof. Some manufacturers of metal roofing, including Kassel and Irons, warrant against loss of impact resistance as well as against leakage due
to hail perforation.
- This is very beneficial because, after a severe hailstorm, property owners
might have to wait several weeks or months for a roofing contractor and they appreciate it
when, with metal roofing, they are not dealing with roof leaks during that period.
- Severe hail can cause indentations to metal roofing.
- Although it varies between various roof designs,
there is little or no damage visible to most metal roof systems after hail measuring up to golf
ball size in diameter.
- Some formed metal shingles, shakes, and tiles have available foam
backers for additional hail resistance.
- In all, metal offers a very wise roofing choice in all
climates including those that are prone to severe hail.
