The cost of Timberline Solar™ is comparable to the cost of buying a new roof plus installing traditional solar panels. As a whole-roof solution, Timberline Solar™ reduces unforeseen costs by streamlining installation from two projects to one, maximizing layout potential with a smaller form factor that can fit around roof obstacles, requiring lower maintenance, and protecting your home from leaks and weather in the same way a regular roof does. As a GAF Energy product, Timberline Solar™ is simply just a roof – with power added.
