Adding new solar panels when roof is replaced?

We used Albion Solar as our solar installer and our general contractor. They worked with Berkeley Roof Services (aka Westco). It was an excellent decision; both service providers are terrific, and it was wonderful to have Albion coordinate all the aspects of the work and make sure that everything was ready for the panels and other materials. https://www.albionpower.com/

Hi, 

We went with NRG Solar for this and we chose them over other solar providers BECAUSE they offered roof and solar together. I regret it profoundly. What that ended up meaning was that they subcontracted the roof work, it wasn't really "in house" - so we were relying on their project managers to coordinate with the roofers, rather than having access to them ourselves. One of the project managers who worked with us was fired for her poor performance. My dad was roofing a workshop in his backyard at the same time and the roof didn't pass inspection because the roofers didn't flash properly. NRG also signed a contract with us and then reneged and would only do the work if we signed a new contract that was something like $10,000 more (they used the online square footage of our house rather than taking actual measurements and failed to account for a 3-4' overhang all around). We ended up getting a different roofer, Richard Kang, who was decent but it was also at a premium price and two years later, we are still waiting on connecting a final drain pipe, and our yard was littered with roofing nails for months afterward (our yard is a bit wild and messy, so I will acknowledge that it is not the easiest area to clean up, but it was still a concern with our small children running around outside all the time). Coordinating the roofer and the solar took a little bit of doing, but it wasn't the worst thing. I will say that we interviewed Jason Hamilton at Earthwise Energy, and I wish we'd gone with him. He does not do roofs, but he works in concert with roofers. His bid was more expensive up front, but my sense was he is very invested in doing things the right way, and what we learned through our two year odyssey of trying to install solar was that other companies seemed to have odd ways of lowballing up front and then changing it (one company, Ally Electric, added several thousand dollars worth of taxes to the contract that were not in their initial bid). Anyway, I found it to be a miserable process, but we are very happy with our solar and I feel relieved not to have to deal with the roof again for another 20 years (hopefully!) Wishing you the best of luck!!
