GAF Timberline ArmorShield II shingles pass UL 2218 Class 4, UL's toughest impact test. The shingles show no evidence of cracks or ruptures, compared to standard shingles which may crak or rupture immediately after large hail storms.
Potential Insurance Savings ... may qualify for insurance discounts of up to 30% or more (check with your agent). Each shingle is labeled with special information that most hail insurers accept.
The UL 2218 Class 4 Impact Test ... drops a 2-inch steel ball from 20 feet onto a shingle to see whether the shingle cracks. The steel ball hits the shingle at 90mph, which is a stronger force than most hail that hits a roof. A typical shingle often has ruptures or cracks on the surface immediately after impact, but Class 4-rated shingles show no evidence of tears, cracks or ruptures on front or back.
Superior Wind Performance ... the highest possible wind rating from Underwriters Laboratories. DuraGrip adhesive seals each shingle tightly and reduces the risk of blowoff.
Exceptional Protection ... includes FLX formula for rubber-like flexibility and ArmorStrip, a patent-pending, puncture-resistant elatomeric tape, for maximum impact resistance. Also includes StainGuard® Protection, which helps protect your roof from ugly algae stains
