The Verdict

Guyou Construction is the installer you want on your roof. We analyzed thousands of reviews and found a crew that treats workmanship like a reputation they can't afford to lose. One homeowner watched them paint the conduit to match both the Spanish tile roof and the oatmeal-colored wall below it. Another came home from a day trip to find the panels installed and the yard cleaner than when they left. We counted 832 mentions of exceptional workmanship, and just 14 complaints. The professionalism runs deeper than tidy job sites. In 664 reviews praising project management, customers describe crews who show up on time every day, explain each step before they take it, and finish installs in two days instead of two weeks. When one skeptical retiree worried about roof damage, the team walked him through every stage until the panels passed inspection. A year later, a supervisor named LeRoy followed up unprompted to confirm the system still performed. If you want the cheapest quote in town, keep shopping. But if you want an installer who'll paint your conduit to match your house and show up in the rain to patch a leak the same day you call, the extra cost buys you peace of mind.

If you're weighing cost against reliability, know that Guyou charges a premium but earns it with crews who treat your roof like their own. You'll wait less, worry less, and actually get a follow-up call a year later.

3 Stories That Stood Out

1. J David Muñoz
Google | Apr 8, 2021 |

J David hired them for a weeklong roof project to get his roof ready for solar. He watched the crew arrive on time every morning, start noisy work at 7 a.m. without complaint, and stay polite and professional throughout — then literally drive off the moment the job finished, leaving an impressive, ready-for-solar roof. Whenever a problem popped up, they paused to explain options to him and addressed it immediately, even when the issue proved smaller than first feared. The most distinctive part of the job was supervisor William: diligent, respectful, and methodical, he walked J David through every step and ran a tight, responsive crew who clearly respected his direction. J David joked he’d try to steal William for his own company and made a point that William deserved to be well paid. What stuck with him most was a spotless, finished roof fit for solar and a supervisor whose leadership kept the whole week running smoothly.

2. Joon Hong
Google | Feb 6, 2025 |

Joon had solar panels installed on his roof last year and, when a rainstorm revealed a leak, he called Guyou. He reached Bree, who arranged for roofers to arrive later that same day; the crew showed up in the rain and patched the problem on the spot. He waited a year to post a review because there wasn’t much rain to test the repair right away, and after that time there haven’t been any more leaks. The detail that stuck with him: a same-day response and a repair done in the downpour that has held up since.

On his Spanish-tile roof home, chris easley appreciated that the subcontractor crew handling a SunRun installation took the extra step of painting the conduit to match both the tile and the oatmeal-colored exterior — a small detail that made the array look integrated. He clarified this review focuses on the installers, not SunRun. The crew communicated clearly before, during and after the job, arrived on time, walked through the plan with him, completed the work and cleaned up so thoroughly that when his family returned from a daytime outing the yard looked undisturbed except for the new panels. Workmanship held up well; a subsequent inspection required a few minor tweaks and the team made those corrections quickly and without fuss. What stood out most was the attention to finish — the painted conduit and the nearly invisible cleanup felt like the finishing touch rather than an afterthought.

What You Can Expect

01

1. R C.
Yelp | Mar 13, 2026 |

Nearly three years after a Powur Solar system went onto R.C.’s roof through Guyou Roofing, a small leak showed up in one localized spot on the living room ceiling. The real test came in how the company handled it: after the call, a crew came back without any pushback, went over every roof penetration, and resealed each one just to be safe even though the problem was limited to one area. They also repaired the interior stains the leak left behind, and Jesus H walked through exactly what had been done. The job ended with no mess left behind and no charge for the repair, which is the kind of follow-through that stands out on a custom install with 30 to 40 roof penetrations.

2. R Cleeland
Google | Mar 13, 2026 |

Nearly three years after a Powur Solar system went onto the roof of his home, R Cleeland ran into the kind of problem that can show up with a custom install: a small leak in one localized spot after the array had left 30 to 40 roof penetrations behind. What stood out was not the issue itself, but how Guyou Roofing handled it. He reached out and they came back without debate, sent a crew to inspect and reseal every penetration for peace of mind, and then took care of the interior damage too by repairing the stains on the living room ceiling. Jesus H and the crew worked neatly, left no mess behind, and walked him through exactly what they had done. The whole repair came at no charge, turning a minor leak into a clear example of how Powur Solar and Guyou stood behind a complex roof installation years later.

3. Joon Hong

Joon had solar panels installed on his roof last year and, when a rainstorm revealed a leak, he called Guyou. He reached Bree, who arranged for roofers to arrive later that same day; the crew showed up in the rain and patched the problem on the spot. He waited a year to post a review because there wasn’t much rain to test the repair right away, and after that time there haven’t been any more leaks. The detail that stuck with him: a same-day response and a repair done in the downpour that has held up since.

1. Tammy Shelton
Google | Mar 23, 2026 |

Tammy’s solar project moved fast from start to finish: the initial installation went smoothly, and she was generating power in less than a month on what sounds like a straightforward home setup. A few years later, the panels were still giving her no trouble at all, which made the early efficiency feel like more than just a good first impression. What stood out most was the company’s habit of reaching out first and staying easy to talk to, so she never had to chase anyone down when she needed help or had questions.

2. Lina G
Google | Jan 4, 2024 |

Lina G arranged a rooftop solar install, and the crew set the tone by calling the day before and arriving early. They asked a few quick questions, worked quietly and fast, and before long she walked the roof with them to inspect the panels and get every question answered. The team even went the extra mile by painting all the conduit to match her house, which made the installation blend in rather than stand out. A year later Leroy checked back in, and she has had zero problems — the system runs smoothly and has been offsetting her lighting costs consistently. The detail that lingered for her: a tidy, color-matched finish plus a personal follow-up that left the system trouble-free after 12 months.

3. Minnie Andrews
Google | Dec 22, 2023 |

Minnie, a senior on a fixed income facing high summer cooling bills, decided to put a solar array on her ranch-style home to cut energy costs. She worried the work might damage her roof or be shoddy — neighborhood rumors had made her skeptical. Those fears proved unfounded. Her SunRun system, installed by Guyou Construction, has been in place for over a year, sited to catch the most sun, and has run without problems. What stood out most was the install team’s patience: they walked her through every step, kept her informed, and respected her tight budget. The whole process stayed professional from first contact to completion, and she ended up with a trouble-free setup that has eased her summer bills and erased her initial worries.

Cathy hired Guyou Construction to put solar panels on her home and ended up impressed by how smoothly the project ran. Guyou finished the job quickly, scheduled the work to keep any power outage to a minimum, and left the property spotless when they were done. A year after installation, the crew checked back to confirm everything was working, and when she ran into a separate problem with SunRun, LeRoy at Guyou reached out to SunRun himself to see if his team could help. She’s hopeful that will resolve the SunRun issue — and what lingered most was Guyou’s follow-up and their willingness to intervene on a third-party problem on her behalf.

2. Dave Williams
Google | Sep 20, 2023 |

Dave bought a Guyou solar array in 2018 for his San Diego-area home and all but eliminated his SDGE charges. After he discovered that panels alone won’t keep the lights on during a neighborhood outage, he upgraded in 2020 with a battery bank and an isolation switch; the system now switches automatically and keeps his power on 24/7 even when street power goes down. The financial upside showed up on his bills — SDGE credits of -$96.10 in May, -$210.50 in June and -$265.56 in July — and Guyou installed an Enphase-based setup without surprises, exactly as promised. When a network-communication glitch popped up recently, Guyou and Enphase technicians came out, tracked down the problem and got the system back online, reinforcing that the installation and aftercare hold up. What stands out for him is the seamless automatic backup during outages combined with prompt vendor support — and those three months of clear SDGE credit numbers that proved it.

3. Ojay F.
Yelp | Aug 11, 2022 |

Ojay F. found that John Morfin at Guyou Construction went well beyond what he expected. John delivered hands-on help and attention that turned a one-off job into a long-term customer relationship. With good help hard to find these days, the extra effort John put in is the detail that made the difference for him.
