The Verdict

Simmitri will fix your roof even during a holiday weekend. We analyzed over a hundred reviews and found two patterns that set this company apart: they treat roofing and solar as inseparable trades, and they answer the phone years after install. One homeowner called on a holiday weekend about ceiling leaks. Simmitri sent a crew that same day, spent two hours tracking down the source, tarped the roof, patched the drywall, and didn't leave until the problem was contained. Another customer changed their WiFi router a year post-install and couldn't reconnect their system. A Simmitri tech walked them through the fix remotely with what the reviewer called "VERY patient" guidance. We found 97 mentions of workmanship quality and zero negative comments about follow-up support. The dual expertise matters because drilling into a roof for solar can create leaks if the installer doesn't understand roofing. Simmitri started as a roofing contractor, so their crews know where not to drill. Bills averaged $40 in summer for one system after three years of operation, exactly as forecast.

If you want the lowest quote, you'll find it elsewhere. But if you need someone who'll show up on a holiday when your ceiling is leaking or patiently walk you through a router issue a year later, Simmitri's roofing background and long-term support justify the premium.

3 Stories That Stood Out

1. Sean B.
Yelp | Jan 17, 2023 |

Sean B. and his wife discovered water leaking through their ceiling on a holiday weekend and felt completely out of their depth with roof repair. He called Simmitri hoping someone would at least pick up the phone, and Viki answered with sympathy and reassurance that the company was working and would do what they could to help. Later that same day Freddie and Reuben arrived, spent more than two hours investigating, and kept at it until they located the root cause—Freddie worked like a roof detective: patient, persistent, and clear in his explanations. They tarped the roof, applied a temporary patch to the large hole in the drywall, cleaned up thoroughly, and left the couple feeling comforted. Having trusted Simmitri years earlier to install their roof and solar, he walked away from this emergency convinced that the company stands by its work—most memorable was that a team showed up during a holiday and didn’t leave until the problem was solved.

2. John S.
Yelp | Dec 19, 2023 |

About a year ago John S. chose Simmitri to replace his roof and add a solar array to his home. From the start Jonathan took a hands-on approach, insisting each step be done right so the job and the customer ended up satisfied. Over the first summer he watched his PG&E bills shrink to about $40 a month, a concrete payoff for the upgrade. When a recent router change left him unsure and the system data stopped reporting properly, he called for help. Nick patiently walked him through reconnecting the monitoring, troubleshooting until the data performed correctly, and stayed with the call until John felt confident. The experience left him with two clear takeaways: consistently low summer bills and a company willing to resolve problems a year after installation.

3. Daniel Anderson
Google | Mar 15, 2025 |

Daniel Anderson researched dozens of solar companies before installing a roof-mounted residential system a few years ago. He ran into salespeople at other firms who seemed more focused on earning a commission than solving his needs, but found Simmitri different: they zeroed in on his particular solar challenge and presented clear options, one of which he chose. Three years after installation he discovered the system produced even better energy than the forecasts predicted. Because Simmitri brought roofing experience to the job, their crew installed the array without compromising the roof—he could tell other companies would have been drilling in ways that created problems. Pricing felt competitive and the process went smoothly; what stuck with him most was the combination of careful, roof-first installation and performance that outpaced expectations, a detail that matters if protecting your roof is a priority.

What You Can Expect

1. Jerry Suarez
Google | Aug 28, 2025 |

Jerry began construction on a new home in 2020, and when it was time to add solar he moved forward with the company. Jonathan guided him through every step of the process, laying out the timeline and next steps so nothing felt uncertain. The installation crew worked quickly, showed clear competence, and handled all the details thoroughly. What stayed with him was the combination of Jonathan’s hands-on guidance and a fast, detail-oriented crew that made the installation smooth and straightforward.

3. Michael MOORE
Google | Apr 10, 2024 |

Michael remembered Pam Garcia and Affordable Roofing from more than twenty years ago, when he needed a roof replacement after his previous install became part of a class‑action settlement. He approached the job looking for honesty and quality and was immediately struck by Pam’s sincerity—skeptical at first, but reassured. When a salesman mentioned a 50‑year top‑line roof he told them he didn’t need that longevity at age 60; the salesman didn’t push. Curious, he called back to ask what made a roof qualify as 50‑year, and the salesperson explained in detail the extra materials and steps involved. Convinced, he paid for the top option and added new rain gutters, both of which performed well over the years. Two years ago a front deck replacement damaged those gutters; Simmitri showed up quickly and repaired them to the same high standard, even offering gutter shields that he politely declined because the professional who cleans his gutters is someone he wants to keep using. The detail that stands out is the combination of upfront, patient explanations about the work and the company’s willingness to return decades later and fix things promptly—those two moments sealed his confidence.

1. Andrea Goldsmith
Google | Nov 3, 2025 |

Andrea Goldsmith hired Simmitri to install Enphase solar panels on her home and later added a battery system. She found the installation team professional and thorough, and the whole setup has continued to run smoothly three years on. The part that stood out was Simmitri’s office stepping in to handle the California document submission, removing the usual paperwork hassle — a practical touch that left her pleased with the outcome.

2. Gloria Collins
Google | Apr 27, 2024 |

In fall 2022, Gloria had Simmitri design a solar system sized for her roof and energy needs. A contracted installation crew showed up on time, got the panels in place, and left a system that has been working well. She especially enjoys the Enphase phone app because it lets her monitor how much energy the panels produce, and she hopes the Enphase battery will become more affordable. The main frustration was Simmitri’s app requiring frequent password sign‑ins; she solved that by adding Enphase’s Enlighten app to her phone to avoid the constant logging in. What stands out from her experience is the ease of tracking production through the Enphase/Enlighten apps after a smooth design and install.

3. Julie Herzig
Google | Apr 15, 2024 |

Julie hired the company about a year ago to replace her home's gutters. She watched the crew work efficiently, finished quickly, and ended up with neat, well-installed gutters that still look great — the speed and clean final appearance were the most memorable parts of the job.

3. Michael Ashley (Mash)
Google | Mar 15, 2022 |

Michael chose Simmitri because his home needed a new roof, new gutters and a solar array all at once — and the company handled the entire package. They replaced the roof, installed the panels and even reworked the gutter layout when his remodel ran behind schedule, adapting the plan midstream so other trades could finish. A year later the system is performing reliably: he monitors generation through Simmitri’s app and is producing enough energy to cover his electricity bills completely, with a surplus beyond that. Throughout the process the team stayed responsive and attentive, and what stuck with him was having one contractor coordinate roof, gutters and solar and make schedule changes without losing momentum — with the app showing the surplus production a year on.
