Shingles Engineered to Endure

How tough are GAF shingles? According to this recent extreme shingle testing demonstration, they’re tough enough to withstand hurricane-force-winds, more water than any rainstorm will hit them with, and a continuous blast of red hot embers. GAF Advanced Protection® Shingles with GAF Dura Grip™ Adhesive are engineered to endure. See for yourself!

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).

What Does Advanced Protection® Shingle Technology Mean To The Experts?

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.

Traditional Shingle Technology

Fiberglass Mat
(the "heart" of the shingle)

  • Low-profile technology includes a proprietary orientation of glass fibers, for maximum strength and durability
  • Typically requires the application of more asphalt (weight) to meet minimum industry requirements

(provides waterproofing performance)

  • Advanced process control allows us to optimize the critical top (i.e., weathering) layer for long-term performance against severe weather
  • More asphalt applied to bottom (i.e., non-weathering areas) increases shingle weight with no added benefit

(mixed with the asphalt to bind components)


  • Premium limestone content optimized for maximum toughness and wind resistance
  • Unnecessary limestone eliminated
  • Unnecessary fillers used to artificially increase shingle weight — with no benefit in performance

(seals shingles on roof)

  • Helps every GAF shingle to comply with AC438, the first shingle tests that use advanced science to predict long-term shingle performance for long-term durability, wind-driven rain performance, and long-term extreme temperature resistance.
  • May not comply with AC438, the first shingle tests that use advanced science to predict long-term shingle performance for long-term durability, wind-driven rain performance, and long-term extreme temperature resistance.

What Does Advanced Protection® Shingle Technology Mean For Nature?

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!

Now, We’ve Taken Shingle Quality To A Whole New Level: AC438

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!
