Not all roofing shingles are the same, which is why the roofing industry tests them. And why we make ours the way we do. Tested Tough!
Shingles are put through a battery of tests to measure their capability and durability. There are 9 standard industry tests, including for rain, hail, wind, fire, strength, and granule adhesion. Tests are performed by outside agencies like Underwriters Laboratory and PGI.
