Tessie Yanes

I am very glad that I decided to give them the contract to replace the old roof of my house. Not only did they redid the roof, but they also installed the Newly designed Solar Panels with it. It is seamless and looks wonderful, no worries about birds or pests taking residence underneath but also supposed to prevent common problem of water leaks through. My roof looks beautiful, what a transformation from the old one. I have nothing but praises to the wonderful staff that took care of this project. Neydi was so efficient in coordinating the process, she has a wonderful personality, very easy to deal and kept me well informed. Alfredo, the project manager also was so prompt with keeping me informed & answered my questions any time. He made sure I am aware of the progress of the project. The workers were very experienced & did not waste time at all. They were very prompt and workmanship was superb. I am very happy and proud I choose them. Yes California roofs & Solar thank you so much for the job well done!
