The Verdict

Sierra Roofing and Solar is a reliable pick for combined roof and solar work. We analyzed hundreds of reviews and found the company excels at managing complicated dual projects, the kind where a crew tears off your old roof, installs new shingles, and then puts your solar array back on without damaging a single panel. One meticulous project manager praised their dedicated solar team for discovering that his original installer had skipped the roof joists entirely and mounted panels straight to the deck, then fixing it properly with code-compliant hardware. Reviews consistently highlight responsive estimators who explain problems without upselling, crews who clean up debris daily, and project managers who chase down unexpected issues like unplanned sheathing needs. We found 111 mentions of solid workmanship and 98 positive comments about post-sale support. The company's strength is execution: they show up on time, finish on schedule, and leave your driveway spotless. What you won't find is cutting-edge solar tech or the cheapest quote in town. (One homeowner noted Sierra's bid came in higher than low-ball roofers but matched top contractors, which tracks with their multi-decade warranties.) If you want a one-stop shop that handles both trades competently and backs the work for decades, Sierra is a safe choice.

If you need both a new roof and solar installation and want one crew handling both without finger-pointing between trades, Sierra is worth the call. You'll pay a bit more than the lowest bidder, but you're buying coordinated project management and long warranties.

3 Stories That Stood Out

1. Aram S.
Yelp | Oct 19, 2021 |

Aram, a meticulous project manager taking on his first roofing job, tracked every large and small detail and did extensive research before signing a contract. After getting three quotes and questioning multiple contractors, he chose Sierra Roofing and Solar for the combination of price, warranty and a team that could remove and reinstall his existing solar array with a dedicated solar crew. He found the whole process exceeded his expectations. The crews moved quickly but carefully, prioritized safety, and tolerated his frequent on-site inspections and technical questions without impatience. Because each Sierra associate answered questions thoroughly and updated quotes when asked, he felt informed at every step instead of pressured. Chris in New Accounts stayed responsive and adjusted proposals for geography, budget and rising costs, listening closely and providing updated quotes without hard-sell tactics. Amber in the office handled the final packet and invoicing with precision. Ivan on production supervised the project end-to-end, obsessing over small details and making sure the company—and the homeowner—remained satisfied even after final payment.

2. Irving A.
Yelp | Aug 27, 2024 |

Irving A. faced a full roof replacement on his 90-plus-year-old Victorian and, after shopping a few contractors, chose Sierra Roofing for competitive pricing. He received a tentative February 2024 start that depended on winter weather, and when an unusually stormy season arrived, Giana at Sierra kept him regularly updated as dates shifted. Once a two-week window firmed up he alerted neighbors so driveways and walkways would be clear on the assigned Monday. The crew rolled up at 7:55 a.m., tarps and sheeting went down, and the team swarmed the roof. The nearly 40-year-old material resisted removal, so the crew worked into the night and finally stopped at 8:45 p.m. because of poor light, notifying neighbors that cleanup and teardown would continue the next day. They returned at 7:30 a.m., finished the demolition shortly after noon, and left the site so tidy there was no sign of the intense work that had taken place. An unexpected need for sheeting cropped up mid-project; the foreman called, arranged the work quickly, and Giana followed up with a confirming call—every surprise got handled promptly and without excuses. Sierra also absorbed changes that Irving admitted were his own,

3. Johnny T.
Yelp | Nov 6, 2024 |

Johnny T. posted a follow-up a week after his initial complaint about the skylights installed during his project. He heard from company leadership almost immediately: Jeff, a business partner, emailed a sincere apology and pledged to fix the problem; David, the project manager, called to gather details and then chased down the skylight vendor. David returned that same day with a concrete solution — replace the skylights with an upgraded model covered by the supplier’s warranty, and the company would absorb the labor cost. Crews came back, worked with a positive attitude and apologized in person. That evening Sean, the general manager and partner, phoned to get blunt feedback, to explain what they should have done from the start, and to listen to how they fell short. Ultimately he accepted that they’d messed up, clarified why things were missed without offering excuses, and committed to doing better. What stuck with him most was leadership stepping in personally and leaving him with upgraded, warrantied skylights and no out-of-pocket labor — a fix and a follow-through that earned his continued business.

What You Can Expect

01

1. Malcolm Humphrey
Google | Mar 6, 2024 |

Malcolm Humphrey has called on Chris and Sierra Roofing for multiple projects over the years. He entrusted them with a complete replacement of his standing-seam metal roof and kept turning to the same crew when questions about adding solar came up. The throughline — reliable workmanship on a major roof job and ongoing, practical help with solar decisions — is what made him keep coming back.

2. Douglas F.
Yelp | Dec 19, 2023 |

After seeing the company's work on his HOA project a year or two earlier, Douglas chose Sierra Roofing and Solar for a full roof replacement on his home. The crew installed the roof and, at the end of each workday, left the area spotless — a consistency he appreciated. Chris ran the project smoothly, and Gianna kept him informed before, during and after the installation. His standout takeaway: solid workmanship combined with daily cleanup and steady communication made the whole process unexpectedly easy.

3. Lisa Woodruff
Google | May 2, 2018 |

Three years after Sierra Roofing and Solar put panels on her Spanish tile roof, Lisa called them when heavy California rains produced a leak. She found the company responsive: they came out, offered a fair price, and returned on the scheduled day to complete the repairs. She plans to confirm everything holds up after the next storm, but for now she’s pleased that the same crew who did the solar work handled the roof issue quickly and without fuss.

1. Gary M.
Yelp | Oct 23, 2017 |

Gary had Sierra Roofing install two roofs on his home, the latest being a tile roof completed about two years ago that still draws compliments. When painters and stucco workers on the front of the house accidentally cracked a couple of tiles, he remembered Sierra had told him to call if anything like that happened and that they would come fix it. He called, Mark came out — pleasant and straightforward — and promised to send a crew in a couple of days. The crew arrived on schedule, used the extra tiles Gary had kept from the original job, replaced 14 broken tiles, hauled away the debris, and left the roof neat. The whole repair took about an hour and was done at no cost, which is what made the experience stand out: a quick, tidy fix that honored the original promise and required no hassle for the homeowner.

2. Chris O.
Yelp | Apr 30, 2010 |

Chris O. hired Sierra Roofing to replace broken gutters on his home and was met with a prompt, reasonable, and accurate estimate to start. The crew completed the gutter replacement cleanly and professionally. A year later the owner happened to drive by, spotted a different gutter sagging, and called to say he'd send someone to fix it; the repair was completed and Chris wasn't charged. What lingered for him was the unexpected, hands-on follow-up — the owner’s willingness to correct an unrelated issue a year after the job at no cost — a level of service that made the whole experience memorable.

3. Jeannie C.
Yelp | Apr 30, 2010 |

Jeannie C. has relied on Sierra Roofing for three years, and the moment that crystallized her trust came during a stretch of heavy rain this year. When new, serious leaks showed up, she called in the morning and the crew arrived that same day to stop the problem — not a band‑aid, but a prompt fix that let her avoid further damage. Over those three years she discovered a team that follows through from the first phone call to project completion, keeps commitments, and charges reasonable rates. She also appreciated that they stayed practical about repairs, doing only what was necessary instead of pushing pricier alternatives. What stayed with her most was that same‑day emergency response paired with a clear reluctance to recommend unnecessary work.

1. Kun Ouyang
Google | May 8, 2025 |

Kun Ouyang returned to Robert eight years after their first installation, and this time he again relied on Robert’s expertise. He found Robert consistently professional throughout the project, so he picked the same person for a second job. The memorable detail is the continuity — the same professional handling both jobs across an eight-year span, which clearly mattered to Kun.

2. jeff m.
Yelp | Aug 16, 2025 |

Jeff hired Sierra Roofing and Solar to redo his roof and add solar panels to his house. He watched Saeng take charge of the roofing crew; they replaced the roof cleanly, stayed in regular, helpful contact, and left him very satisfied with the outcome — getting Saeng to oversee the job felt like a real advantage. The solar installation itself went smoothly and the project manager Alex came across as personable, but Alex missed a few steps and stretched the alarm-system work out by several weeks. Now that the final pieces are finished, he’s waiting for the next PG&E bill, which should show a sharp drop in charges.

3. Charles H.
Yelp | Nov 28, 2025 |

Charles H. had Sierra perform roof maintenance on his house a year ago. When he contacted them recently to arrange gutter work, several calls over several days only reached an answering service and nobody returned his calls. He found that lack of follow-up very unprofessional — the repeated attempts that produced no callback is the detail that stuck with him.
