One of the standout aspects of GAF’s model is its contractor certification program. Contractors who complete the rigorous training program can become GAF Master Elite Certified, a distinction held by only about 2% of all roofing contractors in North America. This certification ensures that customers receive reliable workmanship, extended warranties, and access to premium GAF products.
This commitment to excellence makes GAF roofing systems especially appealing to homeowners who prioritize long-term value and peace of mind.

Advantages of GAF Roofing for Homeowners
Choosing a GAF roofing system means investing in a product that performs well in various climates, including the humid summers and snowy winters of New Jersey.

Whether you want something budget-friendly or bold, GAF offers a style and price point for every roofing project.
GAF Roofing System Components
The strength of a GAF roof system lies in how its components work together. GAF promotes a “complete roofing system” philosophy, designed to provide optimal protection, ventilation, and energy efficiency.
Here’s what’s typically included in a GAF system:
- Asphalt shingles: Available in several lines including Timberline HDZ, AH, and ArmorShield
- Underlayment: Provides a secondary barrier to water infiltration
- Starter strip shingles: Ensure secure shingle alignment and wind resistance
- Ridge cap shingles: Protect roof ridges and enhance curb appeal
- Attic vents and ventilation products: Help regulate moisture and heat
- Leak barriers: Installed in vulnerable areas to prevent leaks
GAF also offers commercial-grade solutions like EverGuard TPO roofing and Quick Spray Adhesives for flat roof applications.
Asphalt Shingles and System Components
GAF’s asphalt shingles, similar to most asphalt shingles, are considered among the most reliable and advanced in the industry. The Timberline product line, especially Timberline HDZ, is known for its high-definition appearance and integrated nailing strip, which improves wind resistance and speeds up installation.
In addition to Timberline, GAF offers:
- Camelot II: High-end designer shingles
- Grand Sequoia: Rustic, large-profile shingles
- Royal Sovereign: Traditional 3-tab shingles for budget-conscious homeowners
The Timberline Solar Roofing System combines the look of traditional shingles with the benefits of solar power, making it a forward-thinking solution for energy efficiency.
For commercial use, products like EverGuard TPO Seam Cleaner and StreetBond pavement coating offer solutions for flat or low-slope roofs.
GAF Roofing vs. Owens Corning
When comparing GAF and Owens Corning, two of the most respected names in the roofing industry, homeowners are often faced with a tough decision. Both brands offer high-quality shingles, robust warranties, and extensive contractor training programs, but there are distinct differences that might sway your choice.
GAF is renowned for its extensive range of shingle styles and colors, making it easier for homeowners to find the perfect match for their home’s aesthetic. Their shingles, such as the popular Timberline HDZ, are celebrated for their durability and resistance to harsh weather conditions. GAF’s comprehensive warranty program, including options like the Golden Pledge Warranty, provides homeowners with peace of mind, knowing their investment is protected.
On the other hand, Owens Corning is a brand synonymous with innovation and sustainability. Their shingles are designed with energy efficiency in mind, helping homeowners reduce their energy bills. Owens Corning’s commitment to sustainability is evident in its use of recycled materials and eco-friendly manufacturing processes.
Both companies offer rigorous contractor certification programs. However, GAF’s Master Elite certification is particularly prestigious, with only about 2% of roofing contractors in North America earning this distinction. This certification ensures that homeowners receive top-notch installation and service, backed by GAF’s extensive warranties.
In terms of cost, GAF and Owens Corning shingles are similarly priced. However, the true value lies in the quality of materials and the expertise of the installation. Investing in high-quality shingles from either brand can lead to long-term savings through reduced maintenance and enhanced durability.
Ultimately, the choice between GAF and Owens Corning will depend on your specific needs and priorities. Whether you prioritize a wide range of design options, superior durability, energy efficiency, or sustainability, both brands offer excellent solutions for your roofing project.
Product Quality and Comparison
GAF roof shingles consistently rank high in third-party testing for impact resistance, wind resistance, and fire ratings. Their proprietary technologies like LayerLock, StrikeZone nailing, and DuraGrip adhesive help GAF roofing systems outperform many competitors.
When comparing GAF to other brands like Owens Corning:
| Feature | GAF | Owens Corning |
|---|---|---|
| Certification Program | Master Elite (Top 2%) | Preferred Contractor |
| Warranty Options | Golden, Silver, System Plus | Standard, System Protection |
| Technology | LayerLock, DuraGrip | SureNail Strip |
| Solar Shingles | Yes (Timberline Solar) | No |
| Shingle Options | Broad, architectural focus | Broad, slightly fewer lines |
Both brands offer great value, but GAF stands out for its certified installer network and integrated solar solutions.
