TSP Roofing & Solar did an outstanding job on our reroof and solar removal/reinstallation. The entire process was smooth, professional, and extremely well organized from start to finish.
The reroof was done thoroughly and with great attention to detail, and the solar system was reinstalled seamlessly. What really stood out was the care they took with our property — including running a magnet over the driveway and yard to ensure no nails or debris were left behind.
Professional, efficient, and high-quality work. I highly recommend TSP Roofing & Solar.

I can’t recommend TSP Roofing & Solar enough. Mario and his team were absolutely incredible. I reached out to over 25 different companies trying to find someone who could handle both roofing and solar together without the hassle of finger-pointing between separate crews. TSP was not only the most affordable option, beating out all those other quotes, but also the quickest to get the job done. They know the ins and outs of integrating solar with an old and new roof, so everything was seamless and cost-effective.
What really stands out is their deep experience in servicing solar systems, not just installing them. That means they’ve thought ahead about long-term reliability. They guided me through the whole process, got all the approvals smoothly, and now I have a perfectly integrated solar and battery system at home. If you want a hassle-free, cost-effective solar and roofing combo, these are the folks to go with.
Lastly, when I asked to spend more on more panels, Mario reassured not to, that I had enough panels for my usage - instead of taking advantage and charging me more. That says it all there.

Mario and crew over-delivered on everything! They recognized we’d need to upgrade our electrical panel and got it approved by PG&E and installed within 30 days, when other installers told us 3—4 months! The solar panel install was flawless, and their quote came in less than other installers with comparable panels and battery. We are extremely pleased with TSP Roofing, from their communication, to managing timelines, and the overall quality of install. Highly recommended!
