What GAF Energy does

GAF Energy is a US-based building-integrated photovoltaics (BIPV) company and wholly-owned subsidiary of Standard Industries, founded circa 2017 to bring solar generation into conventional roofing. The company designs, manufactures, and sells the Timberline Solar™ product line — headlined by the Timberline Solar Energy Shingle (ES), the world's first nailable solar shingle that installs using standard roofing tools and forms part of the roof's primary water-shedding layer, and the second-generation ES2 producing 57W per unit. Manufacturing has been consolidated at a 250MW annual-capacity facility in Georgetown, Texas following the December 2025 closure of the company's former San Jose, California R&D and production site.

GAF Energy generates revenue predominantly through hardware sales of Timberline Solar systems distributed exclusively through certified roofing contractors — leveraging Standard Industries' position as the largest roofing company in North America to bypass the specialized solar installer model. Ancillary revenue comes from contractor training and certification programs. End customers are residential homeowners making roof-replacement decisions, with particular traction in high-energy-cost markets (Hawaii, California, Florida) and hurricane-prone regions. The company holds state contractor licenses across 27+ US states.

The company markets directly to homeowners through content marketing, PR in outlets like Forbes, Bloomberg, CNBC, and a feature on THIS OLD HOUSE, targeting the 'when you need a new roof, go solar' decision point. R&D collaboration with Sandia National Labs and recognition including CES 2022 Best of Innovation and Fast Company World Changing Ideas Award validate its technical positioning.

Revenue model

1. Timberline Solar Roof Sales: GAF Energy generates revenue through the sale of its Timberline Solar integrated roofing system. The system is sold through a network of roofing contractors who install the product for homeowners. Revenue is generated from the hardware (solar shingles, panels, flashing, perimeter shields) as well as the roofing integration components.
2. Contractor Training and Certification: GAF Energy provides training and certification programs for roofing contractors who install their products. This creates a trained installer network while generating additional revenue streams through training programs.

Core offering

GAF Energy designs, manufactures, and sells the Timberline Solar roof-integrated photovoltaic (BIPV) system, anchored by the world's first nailable solar shingle. The product combines roof protection and solar power generation in a single integrated layer, and is sold exclusively through a network of trained and certified roofing contractors across more than 20 U.S. states.

Product overview

GAF Energy offers a unified product line centered on the Timberline Solar™ roof system, the company's flagship building-integrated photovoltaic (BIPV) solar roofing solution. The system consists of the Timberline Solar™ Energy Shingle (ES) as the core component—the world's first nailable solar shingle—and its second-generation variant, the Timberline Solar ES2 with improved power output of 57W per unit. These products directly integrate solar technology into traditional roofing materials and processes, providing dual roof-solar functionality in a single seamless system. All products are manufactured domestically in the USA at facilities in San Jose, California and Georgetown, Texas.

Direct peers

• Tesla Energy (Tesla Solar Roof): Tesla's Solar Roof is the most prominent direct competitor to GAF Energy's Timberline Solar. Both offer integrated solar roof systems targeting U.S. residential homeowners at the re-roof moment; GAF Energy claims to have outpaced Tesla in solar roof installations.
• Luma Solar: Luma Solar produces solar roof shingles and integrated BIPV systems targeting U.S. residential customers. It is a smaller, more focused direct competitor in the same nailable solar shingle category as GAF Energy's Timberline Solar.
• SolarCity (legacy / Tesla Energy ops): SolarCity, now part of Tesla Energy, pioneered the residential solar-as-roof concept and established the category GAF Energy now leads with Timberline Solar. It remains a direct comparison point for go-to-market and customer adoption.

Broad incumbents

• CertainTeed (Saint-Gobain): CertainTeed, a Saint-Gobain subsidiary, is a major North American roofing manufacturer with a solar roofing product line (Solstice). It competes in the same integrated solar roofing category as GAF Energy but as part of a much broader building products portfolio.
• Sunrun: Sunrun is the largest U.S. residential solar installer, offering traditional rooftop PV systems (lease, PPA, cash) that compete with GAF Energy for the same homeowner solar dollars, though via a different technology model.
• SunPower: SunPower designs and sells high-efficiency residential and commercial solar panels, and historically offered integrated roof solutions. It competes for the same U.S. residential solar customer with a different (panel-rather-than-shingle) approach.
• Maxeon Solar Technologies: Maxeon (spun out from SunPower) manufactures high-efficiency back-contact solar cells and panels used in residential rooftop and shingle-style applications. It supplies the underlying cell technology for many BIPV products.
• Hanwha Qcells: Hanwha Qcells is one of the largest global solar panel manufacturers and offers residential rooftop solutions in the U.S. It competes on panel efficiency, price, and warranty against integrated BIPV systems like Timberline Solar.

Others

• Enphase Energy: Enphase is the leading U.S. residential MLPE (microinverter) supplier, a core electrical component in any rooftop solar system including GAF Energy's Timberline Solar. It is an adjacent ecosystem enabler rather than a direct competitor.

Emerging players

• Apollo Power: Apollo Power is an early-stage company developing flexible thin-film solar roofing products. It overlaps with GAF Energy in the BIPV category but with a differentiated lightweight technology and smaller scale.
