Not all roofing shingles are created equal.

The Backbone of Roofing: Rigorous Testing

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!

Malarkey Shingles Put Through Industry Performance Tests

Rigorous Industry Testing

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.

Malarkey Shingles Excel at the 9 Industry Tests

Rain Test

The roofing industry test for rain (TAS 100) measures shingle performance in rainy and windy conditions, helping ensure shingles prevent water penetration.

Wind Test

The roofing industry test for wind (ASTM D3161) measures shingle performance in high wind conditions, helping ensure shingles resist wind uplift.

Ice Ball Test

The roofing industry test for hail (FM 4473) measures shingle resistance to hail damage by propelling ice balls at the shingles to simulate the impact of falling hailstones.

Steel Ball Test

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.

Spread of Flame Test

Part of the roofing industry’s 3 tests for fire (ASTM E108), the spread of flame test measures shingle resistance to fire spreading by blowing a flame across the surface of the shingles.

Intermittent Flame Test

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.

Burning Brand Test

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.

Granule Adhesion Test

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.

Tensile Strength Test

The roofing industry test for strength (ASTM D146) measures the maximum amount of pulling force that a shingle can withstand without breaking to assess its overall strength and durability.
