Whether you’re facing the sweltering heat of summer or preparing for winter’s worst, your roof deserves materials that can handle it all. With a GAF roof and premium GAF shingles, you’re not just choosing a rooftop covering—you’re investing in decades of protection, performance, and style. But what makes a GAF shingle such a trusted choice for so many homeowners, businesses, and professional roofing contractors?

In this guide, you’ll learn about our residential and commercial roofing solutions, the types of roof shingles available, and why the GAF Timberline series has become the #1-selling shingle brand in North America.

What Are GAF Shingles?

Founded in 1886, GAF (General Aniline & Film) has grown into one of North America’s largest and most respected asphalt roofing manufacturers. With over a century of expertise, GAF has built a reputation for producing top-quality residential roofing shingles designed to withstand the elements while enhancing curb appeal.

Whether you want classic asphalt roofing shingles, high-end designer styles, or energy-efficient roofing materials, GAF offers a complete roof system for homes and businesses. Each GAF roofing system is designed for durability, style, and long-term protection—often protected by a GAF roof warranty that outshines competitors.

Types of GAF Shingles

Not all roofing materials are the same, and GAF understands this. That’s why they offer a variety of GAF products to suit different styles, climates, and budgets.

Timberline Shingles: The Best-Selling Classic

Timberline is America’s #1-selling shingle brand, blending durability, affordability, and beauty. These roof shingles mimic the warmth of wood shakes without the maintenance.

  • Timberline HDZ® shingles: Featuring LayerLock™ technology, a limited wind warranty with no maximum wind speed limitation, and high nailing accuracy.
  • Timberline UHD®: Ultra high definition style for a richer, dimensional look.
  • Timberline AS II®: Impact-resistant, Class 4-rated shingles for severe weather, including hail.

If you want a timberline roof that delivers both performance and beauty, GAF Timberline HDZ shingles are a top choice.

Designer Shingles: High-End Style

GAF shingles in the Designer series elevate any roof with upscale appeal:

  • Slateline®: Slate look without the weight or cost.
  • Camelot®: Bold, dimensional lines for architectural distinction.
  • Glenwood®: The most authentic wood shake look in an asphalt roofing shingle.

These shingles offer the elegance of premium materials while being easier to install and maintain.

Impact-Resistant Shingles: Weather Protection

For storm-prone areas, ArmorShield™ II combines GAF Timberline style with UL 2218 Class 4 impact resistance. These shingles help prevent costly repairs and may reduce warranty claims and insurance costs.

Key Benefits of GAF Shingles

Durability and Longevity

Many GAF shingle lines carry a lifetime limited warranty when installed by a contractor certified by GAF and with qualifying GAF accessories like leak barriers, accessory products, and proper nail application.

Weather Resistance

From SBS-modified shingles for flexibility to Stainguard Plus™ algae protection, GAF can help your roof withstand heavy rain, wind, and hail.

Energy Efficiency

GAF Timberline Cool Series® and the Cool Roof Collection reflect sunlight, keeping attics cooler and lowering energy costs.

Warranties

GAF offers coverage up to 50 years on materials and up to 25 years on workmanship, including the Golden Pledge® Warranty. There’s even a 25-year limited warranty on certain roofing materials.

GAF Shingles Installation Process

A proper roof system installation involves:

  1. Roofer for your project inspection by a certified by GAF installer.
  2. Removal of old materials if you’ve replaced the roof before.
  3. Leak barrier and underlayment installation, such as WeatherWatch®.
  4. Precision nail placement for maximum wind resistance.
  5. Adding ridge caps and flashing.

Always hire an installer enrolled in GAF certification programs to ensure your warranty information remains valid.

GAF Shingles vs. Other Roofing Options
