What Is GAF Roofing? Complete Homeowner’s Guide by SRS

If you’ve been researching roofing options, you’ve probably come across the name GAF — and for good reason. GAF is one of the most trusted and recognized roofing brands in North America. But many homeowners still wonder: what is GAF roofing, and what makes it so popular?

At State Restoration Services, we install and maintain high-quality GAF roofing systems every day. In this guide, we’ll explain what GAF roofing is, why it’s different from other brands, and why it might be the best choice for your home.

Understanding What Is GAF Roofing

Simply put, GAF roofing refers to roofing materials and systems manufactured by GAF (General Aniline & Film) — the largest roofing manufacturer in North America.

GAF produces a wide range of roofing products, including:

• Asphalt shingles (the most popular choice)

• Roofing underlayments (moisture barriers)

• Ventilation systems

• Roof accessories such as ridge caps and sealants

When we talk about what is GAF roofing, we’re really referring to a complete, integrated roofing system designed to protect your home from top to bottom.

A Quick Look at GAF’s History

GAF has been around for more than 130 years, earning a reputation for innovation, quality, and reliability. The company has become the #1-selling shingle brand in the U.S., trusted by both homeowners and professional contractors.

Their long-standing commitment to improving roofing technology has made GAF a leader in both residential and commercial roofing systems.

What Makes GAF Roofing Different?

When homeowners ask us, “What is GAF roofing, and why should I choose it?” — the answer lies in three key benefits: quality, variety, and protection.

1. Superior Quality

GAF shingles are engineered to handle harsh weather conditions — from heavy rain and snow to extreme heat and wind.
They use advanced fiberglass technology, sealant protection, and granule adhesion that helps resist cracking, curling, and fading.

2. Wide Variety of Styles and Colors

Whether you prefer a classic, modern, or high-end look, GAF offers shingles to match any architectural style.
Some popular GAF lines include:

• Timberline® HDZ – America’s #1-selling shingle for a dimensional, architectural look.

• Royal Sovereign® – A cost-effective 3-tab shingle for simple elegance.

• Timberline® UHDZ™ – Premium shingles with deeper color contrast and a refined finish.

• Designer Series – Mimics the look of natural wood, slate, or tile.

3. Industry-Leading Warranty Protection

GAF is famous for offering some of the strongest warranties in the roofing industry.
When installed by a GAF-certified contractor (like State Restoration Services), homeowners may qualify for extended warranties that cover both materials and workmanship — for up to 50 years.

What Is a GAF Roofing System?

When learning what is GAF roofing, it’s important to understand that it’s not just shingles. It’s a complete roofing system, with every layer designed to work together.

Here’s what a typical GAF roofing system includes:

1. Leak Barrier: Protects against leaks in vulnerable areas like valleys and eaves.

2. Roof Deck Protection: Shields the deck from moisture infiltration.

3. Starter Strip Shingles: Helps prevent shingle blow-off in high winds.

4. Lifetime Shingles: The visible top layer that provides both beauty and protection.

5. Ridge Cap Shingles: Enhances ventilation and gives your roof a finished look.

6. Attic Ventilation System: Ensures proper airflow to prevent heat and moisture buildup.

Each component is designed to reinforce the others — giving your home maximum protection and extending your roof’s life.

The Benefits of Choosing GAF Roofing

So, what exactly makes GAF roofing stand out compared to other brands? Let’s break it down:

1. Long-Lasting Durability

GAF shingles are tested to withstand winds up to 130 mph, making them ideal for areas with unpredictable weather.

2. Energy Efficiency

Some GAF products are ENERGY STAR® certified, reflecting more sunlight and reducing attic temperatures — which can lower your energy bills.

3. Beautiful Curb Appeal

With dozens of color options and architectural styles, GAF shingles can transform the look of your home while increasing its resale value.

4. Excellent Warranty Coverage

From basic to comprehensive lifetime coverage, GAF warranties give homeowners peace of mind that their investment is protected.

5. Sustainable Materials

GAF is committed to sustainability. They use recycled materials and have introduced Timberline HDZ® Roofing Shingles, which are part of the RoofCycle™ recycling program.

What Is GAF Roofing Certification (and Why It Matters)

One of the biggest advantages of GAF roofing is that it’s often installed by GAF-certified contractors.

These roofing professionals undergo special training and meet strict quality standards. This ensures your roof is installed correctly and qualifies for the best warranties available.

At State Restoration Services, we are proud to work with GAF materials and uphold their high installation standards. This means when you choose us, you’re not just getting a roof — you’re getting guaranteed quality and protection backed by GAF.
