GAF Timberline Solar™ shingles are the first nailable solar roof on the market. But are they worth the premium over traditional rack mounted panels? We crunched the numbers from our last 50 installs.

What Makes Timberline Solar Different

Unlike bulky rack mounted panels, Timberline Solar shingles install with standard roofing nails and integrate seamlessly into the roof line. The result is a sleek, low profile system that looks like a premium architectural roof.

The Numbers

  • Average bill reduction: 40 to 70%
  • Federal tax credit: 30% of system cost
  • Typical payback period: 7 to 10 years
  • Warranty: 25 years on power output

Most homeowners save $35,000+ over the life of the system.

Who It's Best For

Homeowners who already need a roof replacement get the most value, you're paying for one product (a roof) that also generates power, instead of layering panels onto a roof you'll replace in 15 years.
