Thanks Volt! I highly recommend this roofing and solar company. Buck and his team are great: very…read moreknowledgable, hard-working, and have amazing attention to detail. On top of that, they're just good down-to-earth people. We hired them last spring to re-roof our home, replace some rotted eaves and fascia and replace our old solar system (it was inefficient and malfunctioned quite a bit). We are very happy with what we got for the price we paid, it was a good value. It looks so much better than it did before and is consistently producing more energy. I feel like they helped us make the right decisions through the whole process, especially for system size to be able to keep our NEM1 status. The new roof looks great and works really well. I waited almost a year to write this review to make sure there wasn't any water intrusion during the winter storms - not a drop anywhere. They were in the mid-high range in pricing on the bids we got, but I'm happy we spent a little more went with them. Can a roof be sexy? Ours sure is. All in all, if you need a new roof or solar system or home battery, or all of the above, call Volt. They are a competent and professional group of local people who are really f**king good at what they do.

After much research, we had the top six companies quote us estimates for solar on our Loomis house…read more I noticed that each company explained the process differently; some explanations were good, while others left me more confused. When Buck arrived, he stayed until we were satisfied with our understanding, and I learned so much more from his explanations than from all other companies. Considering they were also roofers and understood the difficulty with our high-pitched roof, we placed more confidence in them than the others. Hence, we chose them after a month of research and estimates. Kristen, their assistant manager, was very communicative throughout the entire project, keeping us informed about what was happening behind the scenes with permits, PG&E approvals, and the team's schedule. That helped us understand the project's time frames. Bucks crew -- Jared, Sean, and the others -- were friendly and professional. They worked quickly and efficiently to finish the job, paying close attention to detail. They went above and beyond, including sharing additional insights about our gutters and attic. I could tell they understood the bigger picture, and I am grateful for their effort. After researching many companies, we are happy we chose Volt Modern and will definitely recommend them to others looking for solar installation and roofing services.

The men that work for your company have been on the site of my apartment complex for several months…read morenow. They worked inside my home and they're also working outside of my home.. They have treated my home my yard and my plants with absolute disregard. They dragged their hoses right through the middle of my flowers and plants and into the door of my apartment and after they put the brand new flooring down in my bathroom, they destroyed. It was some kind of chemical that left white spots all over the floor. And then even after asking them several times to please pick up their garbage they use our parking lot in our residence like it's their own personal trashcan. I could go on for a long time, but it wouldn't be worth it to me. Please think twice before you allow these disrespectful people to come and treat your home the way they have treated mine.

We had Citadel replace our roof and add solar several years ago. We chose Citadel because it is a…read morelarger company and I wanted the peace of mind that brings in case something goes wrong. We have a complicated roof-line and Citadel did their best to squeeze as much solar as they could onto it. The roof work was quick and done well. They stayed in communication via email and kept us in the loop. Our sales rep, Liam, was great. The reason for my review now, is that we had a small gutter leak develop in a very inconvenient place, right over a doorway. I emailed Liam about it as a warranty issue and they sent someone out within a couple days. Unfortunately, during the next rainstorm we discovered that their first visit didn't solve the problem. I emailed Liam about it again and they came back out again in a few days, and this time fixed the problem for sure and tested it. The easy service after the fact really makes me glad I chose them!

The prices and quote times were made VERY clear ahead of the work so that I knew what I was getting and for how much. Two examples of Phase One going extra / above and beyond are their willingness to take feedback and send someone out, one day after the job was done to fix one small cosmetic thing I'd found after work was complete. Most other contractors once they're paid are really hard to get a hold of, but not Chris at Phase One. Super responsive. They have experience working with the City Offices here and their comfort with the inspectors who show up is because they stand by their work. All in all this is a good business that I hope to see stick around for a long time. You can add me to the list of people who think this company should be your first call in this area.

The quote for solar didn't have the best price but it was comparable to others. They proposed an expensive Enphase storage unit that has 10 kWh storage and 3.8 kW output. I explained that 3.8 kW might be problematic during power outages and I didn't want to spend so much money on a poor fit. The owner called to trash talk competing storage for 10 minutes. It was awkward, inaccurate, and irrelevant to me finding the right equipment.
