Gen819 Roofing & Solar reviews

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.
Reviews That Shaped Our Verdict
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.
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.
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.

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.
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.
