Best Insulation Replacement in Phoenix AZ

We got quotes from numerous companies and decided on sunpower. Happy we did! The process  was easy and the project went smooth. Chad our representative was great and sent us updates often so we always knew what was going on. Only giving 4 stars because while they were working on the roof, they dropped soooooo many nuts and bolts and if my dog had one hit it's head it could have been pretty painful or my child coulda picked it up and choked on it. They did however go around and clean up anything the dropped after the fact. (So just watch your head while the are bolting things on the roof ) They also knocked our vent hood off and it took me a couple of times asking before it was put back on, but again no biggy and honestly, overall I think it's a wonderful company and those two minor things shouldn't detour anyone from checking them out. Our panels look great and again, every rep/worker was sooo kind and courteous. We've only had solar up for a month or so but so far so good!
