There are a lot of reviews about Green Conception's solar installation but their roofing expertise is what saved me. I couldn't ignore the many shingles blown off my roof anymore (thank you Santa Ana winds) but didn't realize how difficult it would be to re-roof with existing solar panels that would need to be PROPERLY removed and reinstalled after the roof was done. The general contractors I contacted initially said they would have to "contract out" the solar panel removal and reinstallation because they didn't have anyone who knew how to do it right (and that, of course, would cost more and take longer) and even a couple of other solar companies I contacted didn't do roofing at all or didn't want to bother since I didn't want to change out the solar panel system. Roof replacement with an existing solar panel system is an ACTUAL service that Green Conception provides. No hemming and hawing about price (no surprise issues during the work luckily either so no price adjustments needed); no hard sell to upgrade the solar system (admittedly I probably should though). Very professional and knowledgeable (I had no idea roofing materials made a difference for solar). My only gripe is that, because the solar tax credit is expiring this year, they had a lot of projects going on and didn't always get back to me as quickly as I would have liked and it took a little longer than I hoped, but they had the forethought to warn me about that beforehand, so it was expected. All in all, very happy with them.
