What Is a GAF Class 4 Shingle — And Why It’s Different

Most shingles look the same from the ground. But not all shingles are built the same.

A GAF Class 4 shingle is the highest-rated shingle you can get for impact resistance. That means it’s been tested to handle the worst: hailstones, flying debris, and the pounding storms we get here in Texas. Insurance companies and roofing pros consider Class 4 the gold standard.

Why it’s different:

  • Impact tested. Class 4 shingles are hit with steel balls in a lab to mimic hail. If they don’t crack or break, they earn the rating.
  • Real storm protection. Designed to withstand golf-ball sized hail and winds up to 130 mph.
  • Longer life. Less damage means fewer repairs and more years out of your roof.
  • Insurance savings. Many insurance companies give discounts on premiums when you upgrade to Class 4.

With GAF Class 4 shingles, you’re not just buying a roof. You’re buying peace of mind — knowing your home is protected by one of the strongest shingles on the market, backed by GAF’s name and our lifetime workmanship guarantee.

I recently moved back into my childhood home and needed some roofing done. I reached out and ******* did everything I asked and more. I had plenty of questions and he addressed them all being making sure I was knowledgeable and comfortable until the completion of the project!
