The New GAF Solar Roof: Cost & Comparisons – The Ultimate Guide

May 17, 2022April 29, 2022

Solar tile roofs are becoming a popular option for homeowners who want to use renewable energy. Instead of installing solar panels on top of your roof with a racking system, photovoltaic cells are integrated directly into the shingles or tiles that make up your roof.

Both BiPV shingles and traditional solar arrays offer a service life of 25 years or more, and they make sense from a financial standpoint. However, if you’re among the homeowners who prefer the look of a traditional roof without PV modules, you might be interested in a solar roofing system.

GAF is an established provider of high-quality roofing materials, and they recently developed the Timberline Solar Energy Shingles. This product is characterized by being the first nailable solar shingle in the market, which makes the installation process much simpler.

GAF has designed a solar shingle that can be easily installed by roofing contractors, making the overall process easier for homeowners.
Normally, homeowners need to contact two separate companies to install their roofs and solar panels.

GAF offers complete roof replacements that include solar shingles, similar to how Tesla Solar Roof works. In other words, you cannot use their solar shingles for a partial roof upgrade. This is not a problem for new construction projects and homes that require a complete roof replacement.

However, if your roof is relatively new and in good condition, traditional solar panels have a lower cost and a quicker payback period. There are also solar shingle providers who offer partial upgrades, where only the roof areas that will be used to generate electricity are upgraded.

GAF: Innovation is a part of their DNA

GAF stands for General Aniline & Film, and they are currently the largest provider of roofing and waterproofing solutions in North America.

GAF introduced the Timberline roof shingle in 1967, and it became one of the most popular roofing products in the US. One of the companies that merged to create GAF was RUBEROID which launched the first individually cut asphalt shingle in 1912, and the first interlocking shingle in 1933.

GAF Energy was created in 2019 as a separate business unit, with the goal of providing solar solutions for residential and commercial buildings. GAF and GAF Energy are sister companies, both owned by Standard Industries. There are two main product lines:

The DecoTech system integrates solar panels into the roof structure, allowing a flush installation without separate racking.
The Timberline Solar roof system uses solar shingles instead of traditional PV modules, and GAF has developed the first nailable solar shingle in the world.
