Temp test on 70F day. Old roof:
And new roof:
The whole house pic doesn't do it justice due to low resolution. It is a very pretty light gray with some visual texture to it. A poll of my neighbors showed that most preferred it to the color of my old roof.
This was the first solar reflective roof my roofer had done. His comment when we were on the roof together inspecting the job? "Wow! It actually feels cool up here! Most roofs you just feel baked from below."
Can you say "improved PV array efficiency?"
