The Verdict

Gen819 delivers installation work that stands up to San Diego's weather. When a summer rainstorm caused leaks during one flat-roof job, the crew returned the same day to fix and repaint the damage so thoroughly you'd never know it happened. We found 25 reviews praising workmanship quality with zero negative comments, the clearest signal a contractor will do the job right. The company excels at two things most installers struggle with: metal roof installations (which one homeowner researched for two years before choosing Gen819 over every other local specialist) and navigating permit approvals through Southern California Edison without the customer chasing paperwork. Marcus, the owner, answers questions directly rather than routing you through a call center. One condo HOA received multiple unaffordable quotes from competitors, then got a workable TPO quote from Gen819 the next day with no surprise charges at completion. The catch: two customers reported verbal quotes that tripled in writing, so insist on a written estimate before you commit to anything.

If you want the cheapest bid in town, keep shopping. But if you need a crew that'll come back the same day when weather exposes a problem, and you value direct access to the owner instead of a project coordinator, Gen819 is worth the premium.

3 Stories That Stood Out

1. Carol Y.
Yelp | Sep 4, 2020 |

Carol Y. turned to Gen819 after a friend recommendation when she decided to put solar on her flat-roofed house. Marcus came out to inspect the roof and came back with a quick, clear quote. Gen819 took care of all the paperwork and permits, and they even rearranged the panels to the spots she preferred — then secured permit approval for that layout. The installation crew worked professionally and efficiently and left the site clean. A brief summer shower during the install caused some leaks into the house and garage, and the team rushed back to repair and repaint so there were no visible signs of water damage. Because the roof is flat, they also went over every penetration with a blowtorch to seal the holes; she’s waiting to see how those seals hold up in the next heavy rain. The most memorable part of the job was how quickly they came back and made the leaks disappear, then repainted so the repairs blended in.

William Rice spent two years researching metal roof installations before moving forward. He interviewed the only local contractors who handle metal roofs, visited two Riverside manufacturers that produce metal roofing materials, and ultimately chose Gen819 for a metal roof and solar system on his Carlsbad home. What set the job apart was the level of craftsmanship and attention to detail—Gen819’s work stood above the rest—and when issues arose Marcus personally stepped in to correct them. He ended up with a neatly finished metal roof and functioning solar array, and the fact that mistakes were fixed promptly by the crew is the detail he remembers most.

3. Mark S.
Yelp | Jun 1, 2020 |

Mark built a small addition on his house and needed a roofer to finish the new roof. He sent Marcus, the owner, the architectural plans; Marcus came out to inspect the site and offered a verbal price of $2,000 for the entire job, materials included. That turned out to be the last straightforward part of the process. When the addition reached the roofing stage, he found it like pulling teeth to get a written estimate, and when one finally arrived it listed $6,000 — three times the original verbal figure — even though the scope hadn’t changed. He declined to hire Marcus and walked away frustrated; the detail that sticks is the 3x jump from a verbal $2,000 to a written $6,000 with no scope change, so insist on a written quote before you proceed.

What You Can Expect

William Rice spent two years researching metal roof installations before moving forward. He interviewed the only local contractors who handle metal roofs, visited two Riverside manufacturers that produce metal roofing materials, and ultimately chose Gen819 for a metal roof and solar system on his Carlsbad home. What set the job apart was the level of craftsmanship and attention to detail—Gen819’s work stood above the rest—and when issues arose Marcus personally stepped in to correct them. He ended up with a neatly finished metal roof and functioning solar array, and the fact that mistakes were fixed promptly by the crew is the detail he remembers most.

2. Chris O'Neill
Google | Jun 28, 2025 |

Chris ran an HOA for a residential condo building with an aging roof that needed replacement, but initial bids came back so high the project felt out of reach. He reached out to Marcus, who delivered an affordable quote the next day that used the TPO membrane the board wanted. The crew kept communication simple, moved through the work without surprises, and wrapped the job right on schedule with no unexpected charges. What stuck with him was getting the exact TPO solution at a price the HOA could afford—quoted within a day and installed on time with transparent billing.

3. Robin C.
Yelp | Apr 16, 2025 |

Robin spent more than three years evaluating options before replacing a wood‑shake roof with a Cedur synthetic roof in the Gen819 profile. They loved the finished look. Marcus’ crew ran the install — punctual, tidy, friendly, communicative and accommodating from start to finish. What stuck with them was that the Gen819 result matched their long search and the team's reliable, clean execution.

02

1. Struggle F.
Yelp | Dec 21, 2022 |

Struggle picked Marcus and his Gen819 team to install solar on their Southern California home, and what stood out was how hands-on the crew stayed. Erik and Susie stayed reachable the whole time, guiding them through city permits and the final interconnection with Southern California Edison until approval came through. The installation itself impressed—Struggle left an A++ for the workmanship—and the team’s responsiveness made the process smooth. They plan to call Gen819 back when they’re ready to add more panels.

2. Tony M.
Yelp | Sep 26, 2022 |

Tony M. hired Marcus to oversee his home solar installation and discovered Marcus stayed personally involved at every stage. Marcus remained reachable for questions, fielded concerns quickly, and delivered thorough answers, which kept the project moving and reassured him. The thing that stood out was Marcus’s hands-on, always-available approach from start to finish.

3. Adil Y.
Yelp | Dec 1, 2020 |

On a block where nearly every house already had solar, Adil Y. compared several bids and chose Gen819 for their dedication, personal touch and flexibility combined with competitive pricing. He ended up with what he considers the prettiest installation in the neighborhood because the crew paid attention to curb appeal: where possible they tucked conduit into the roof and routed the array exactly where he wanted it, avoiding the exposed piping that ruins a roofline. Gen819 installed the latest solar technology, worked with meticulous care, and handled any post‑installation issues quickly. He also had a flat roof repaired during the same job, so everything was completed in one go without long delays. The detail that stayed with him was how the team protected the roof aesthetics—hidden conduit and precise panel placement made the difference.

03

1. Agnieszka Giacalone
Google | Feb 24, 2023 |

Agnieszka followed Marcus’s recommendation to size the system so her electric bill would fall to the minimum. She ended up with rooftop panels that are performing excellently and a crew that delivered consistently strong customer service throughout the process. Grateful for the outcome, she thanked the team and passed the company name along to others. The detail that sticks: practical sizing advice that produced a real reduction in her electric bill.

3. Anja S.
Yelp | Apr 3, 2020 |

Anja S. compared several roof-and-solar options before choosing Gen819 Roofing and Solar for the job on her home. She found owner Marcus Maedl deeply knowledgeable—he walked her through every option, adjusted the plan to match her wishes and needs, and worked to deliver the best possible price. The project moved smoothly from pulling permits through installation to the city inspector’s final sign-off and finished on schedule. Although a small team, they delivered quality work that stood up to larger competitors, and she referred Marcus to many other clients who also had positive outcomes. The detail that stuck with her was the owner’s hands-on guidance combined with a seamless, timely permit-to-inspection process.
