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.
The roofing industry test for hail (UL 2218) measures shingle resistance to hail damage by dropping steel balls on shingles from 20 feet in the air to simulate the impact of falling hailstones. Malarkey shingles excel at the steel ball test, earning a Class 4 impact rating (the highest impact rating possible)!
Part of the roofing industry’s 3 tests for fire (ASTM E108), the spread of flame test (ASTM E108) measures shingle resistance to fire spreading by blowing a flame across the surface of the shingles. Malarkey shingles excel at the spread of flame test, earning a Class A fire rating (the highest fire rating possible)!
Part of the roofing industry’s 3 tests for fire (ASTM E108), the intermittent flame test measures how well shingles withstand repeated exposure to fire by applying fire to shingles in intervals. Malarkey shingles excel at the intermittent flame test, earning a Class A fire rating (the highest fire rating possible)!
Part of the roofing industry’s 3 tests for fire (ASTM E108), the burning brand test assesses fire resistance by allowing a wooden block to burn atop shingles. The test is performed 3 times. Malarkey shingles excel at the burning brand test, earning a Class A fire rating (the highest fire rating possible)!
The roofing industry test for granule adhesion (ASTM D3462) measures how well the granules adhere to the asphalt surface of shingles, a key determinant in shingle longevity. Malarkey shingles excel at the granule adhesion test, earning a 3x better granule adhesion score than the standard shingle.
