Gideon's metal roofing panels have the highest impact resistance and hail rating granted by Underwriters’ Laboratory (UL), a leading product safety testing and certification organization. Earning UL2218 Class 4 rating, means that a sample of the product did not crack when hit twice in the same spot by a 2-inch steel ball which, in a storm, would translate into a huge hailstone.
Flying embers from an adjacent home or ground fire can land on your home's roof and ignite your roof. Protecting your home with roofing material that carries a Class A fire rating, the highest available, can mitigate disaster. Class A roofing must be able to withstand flames for up to four hours and meet or exceed testing criteria as outlined by UL 790.
Many building officials in the U.S. strongly encourage all new or replacement roofs to be metal to help “harden homes” in hurricane-prone areas. Designed to withstand winds in excess of 140-mph (equal to a F2 tornado), UL 580 is the rating to achieve for protection against severe winds.
One of the keys to the exceptional performance of metal roofing in high winds is due to its attachment methods and interlocking installation where panels are overlapped and attached to the structure of the building, reducing the ability of wind to catch on the actual roof. Proper installation also is paramount.
