We’re fanatical about testing...

When you install a GAF Advanced Protection® Shingle, you’re getting the very best combination of weight and performance that modern manufacturing technology can deliver. In fact, we perform 4,375 quality checks in the manufacture of our Advanced Protection® Shingles. The result? No one makes a better asphalt shingle for: 

• Toughness
• Wind uplift resistance
• Flexibility
• Fire resistance

GAF shingles pass the industry’s two toughest wind resistance tests: ASTM D3161, Class F, 110 mph, and ASTM D7158, Class H, 150 mph (testing performed under controlled laboratory conditions).

Some people think asphalt shingles are just a low-tech (albeit highly effective) roofing material.

But GAF has turned the art of making roofing shingles into a science, with its Advanced Protection® Shingles. Utilizing some of the most advanced design, manufacturing, and testing techniques available in any industry (including test models similar to those used in America’s space program), the result is today’s most advanced roofing technology — now available to consumers to protect their homes.

Everyone wants to do their part to be environmentally responsible. GAF Advanced Protection® Shingles:

• Eliminate the unnecessary waste of natural resources, because they use less asphalt and limestone than conventional shingles
• Reduce transportation waste, because they are weight-optimized to minimize fuel use
• Result in less landfill waste, when the shingles are eventually replaced
• Can be recycled to benefit the environment. That’s why GAF supports a recycling program that allows our contractors to recycle old shingles for reuse in roadways!

AC438 is the first set of tests for shingles that uses advanced science to predict long-term shingle performance in three critical areas:

• Long-term durability: How your shingles perform after long-term exposure to the sun (the #1 enemy of your shingles).
• Wind-driven rain performance: How your shingles will stand up to heavy, driving rains.
• Long-term extreme-temperature resistance: How your shingles withstand extreme temperatures — like the cold of winter in Montana or the heat of summer in Arizona.

All GAF Shingles have passed the requirements of AC438. GAF was the first shingle manufacturer whose shingles passed these torturous tests. We think Mother Nature would be impressed!
