Class 4 Hail Resistant Roof Tile
Impact Resistant Roof Tile
Hail storms ravage the U.S. and wreak havoc every year. These are costly natural disasters; however, there is a concrete solution.
Boral Roofing is proud to announce our new Class 4 Hail Resistant Roof Tile, awarded the highest hail performance certification recognized in the industry. These Class 4 tiles withstood sequential 2 inch ice ball impacts at speeds of up to 70 mph.(1)
Factory Mutual Tested
Specially designed to perform in hail storms, our Class 4 Hail Resistant Roof Tile has undergone severe impact resistance testing in accordance with the Factory Mutual 4473 (FM 4473) standard.
The test uses the impact forces of freezer ice balls propelled to develop free-fall kinetic energies of the same size hail. Ice balls generally are harder and denser than hailstones; thereby simulating the worst case hailstone. In the Class 4 hail test, 2 inch ice balls are shot at 104 feet per second (approx. 70 mph), which is the speed necessary to develop the intended kinetic energy. The Class 4 hail test is the most rigorous test using the largest ice balls, impacting the product specimen 4-6 times depending on the amount of exposed area. Impact locations included edges, corners, unsupported areas, overlaps and joints. After impact testing, the roofing materials are visually scrutinized and to pass, the test specimens cannot show any evidence of visible cracking or breakage.(2)
What if I Have to Repair My Roof?
Because each tile is individually attached, tile is easy to repair or replace. Installation and maintenance costs over time are lower than other roofing materials because concrete tile is made to last for generations.
Class 3 Hail Rated Tile
Boral Roofing has a complete offering of Class 3 Hail Rated clay and concrete tile, including the only clay tile in the U.S. to receive a Class 3 Hail Certification with our 1-Piece “S” Tile. In the Class 3 hail test, 1 3/4 inch ice balls are shot at 104 feet per second (approx. 70 mph) impacting the tile.(1)
