Top Rated Solar Companies Serving Castro Valley, CA

A: Verified High Definition Solar Customer, 1 of 250
"I like the fact they did both roofing and solar. They have to do them together, if you ever have looked into the solar, you will notice companies will recommend this. Because I'm very picky about what I have done to my home, they were tolerant of this fact and didn't mind me watching them closely. They had a good plan and are very organized." - Peter G.

Verified Sierra Roofing & Solar Customer, 1 of 323
"The job I selected was spray on all continuous film on a flat roof that wasn't a commercial building. I went walking on the roof to check out the job and noticed that some areas of the roof are hidden by some walls so near there, some areas hadn't been done. I called them to let them know and they immediately came over and corrected the problem. I'm satisfied. The courtesy they have for the customer and they explain everything pretty nicely. When they came back so I could sign the contract, I wanted a change, and they changed it so they were flexible." - John O.
