GAF and GAF roofing materials

GAF Monaco

GAF works harder so GAF roofing works harder, delivering GAF roofing materials with the superior quality and longevity you want for your customers. GAF is so confident of the excellence designed into its products, it is the only roofing manufacturer to test and list its products under the stringent, new AC438 acceptance criteria.

AC438 was established by ICC Evaluation Services* to evaluate asphalt shingles. AC438 includes the same physical performance requirements found in the less rigorous ASTM D3462 standard, but it also tests for weather resistance, temperature cycling, and wind-driven rain.

Why is AC438 important?

AC438 is the first standard for asphalt shingles that tests the performance of the shingle after accelerated aging. Under ASTM D3462, asphalt shingles are only tested at the time of manufacture. AC438 is the first set of tests for shingles that addresses long-term shingle performance in three critical areas:

  • Long-term durability: How shingles perform after long-term exposure to the sun.
  • Wind-driven rain performance: How shingles will stand up to heavy, driving rains.
  • Long-term extreme-temperature resistance: How shingles withstand extreme temperatures, both cold and hot.

All GAF shingles passed the requirements of AC438. GAF is the first shingle manufacturer whose shingles pass these torturous tests.

“In 2012, we pursued and received an evaluation of our asphalt shingles to AC438 (ESR-3267), becoming the first shingle manufacturer to provide independent verification to these additional physical performance requirements,” says Helene Hardy-Pierce, Vice President of Technical Services, Contractor Services.

“We consider this achievement further evidence that we are manufacturing shingles that will deliver long term, sustainable solutions to the marketplace.”

The result? No one makes a better asphalt shingle for:

  • Toughness
  • Granule adhesion
  • Wind uplift resistance
  • Flexibility
  • Fire resistance

Every GAF shingle on the market today complies with both ASTM D3462 and AC438. And GAF is also the first manufacturer that can say all of its GAF roofing materials and shingles pass the industry’s two toughest wind resistance tests: ASTM D3161, Class F (110 mph) and ASTM D7158, Class H (150 mph).

GAF has turned the art of making roofing shingles into a science with its Advanced Protection Shingles, which use some of the most advanced design, manufacturing and testing techniques available. The chart below shows some of the benefits of GAF’s Advanced Protection shingles as compared to ordinary shingles.

 

GAF roofing materials GAF Advanced
Protection Shingles
Ordinary
shingles
Fiberglass mat

 

Low-profile technology includes a proprietary orientation of glass fibers Typically requires application of excess asphalt (weight) to meet minimum industry   requirements
Asphalt Advanced process control optimizes the critical top layer for superior long-term   performance against severe weather Excess asphalt applied to bottom increases shingle weight with no added benefit
Filler
(mixed with the asphalt to bind components)
Premium limestone content optimized for maximum toughness and wind resistance. Unnecessary   limestone is eliminated Unnecessary fillers used to artificially increase shingle weight—with no benefit in  performance.

Excessive filler can increase the risk of shingle cracking

Adhesive Proprietar  Dura Grip Adhesive locks shingles tightly in place. Allows every GAF   shingle to pass the industry’s two toughest wind tests May not meet wind resistance tests (ASTM D3161, Class F, 110 mph and D7158, Class H, 150 mph)
