How does Preman Roofing and Solar compare where you live? Rankings are local; an installer that leads one city can trail in the next. See how they rank in your city →

Why this differs from star ratings: most five-star reviews say “great company” and stop, and star averages reward that. These category scores only count reviews with concrete evidence, weighted by recency and the reviewer’s track record. A company can hold a strong star average while specific categories score lower; that gap is usually where the real story is. Categories with more complaints than praise are the questions worth asking any bidder, not necessarily dealbreakers.

County-by-county activity from CPUC records through May 2026.

What this data covers: *Counts on this page, including the totals up top, come from investor-owned-utility interconnection records (SCE, SDG&E, PG&E). Work in municipal-utility territory, such as LADWP or city utilities, and outside California does not appear here, so this company's true totals are higher than shown. Unlike the county rankings, this profile also shows counties below the 250-install ranking floor.

Preman Roofing and Solar reviews: what customers say

An independent synthesis of published customer feedback across Google and Yelp, updated September 28, 2026. Green marks praise, amber mixed experiences, red complaints.

Sales & proposal integrity

Sales Integrity6.4/10

Reviewers most often describe the sales process as clear and thorough, with several noting detailed initial meetings and careful explanations. The main complaints center on expectations that felt overstated or incomplete, including panel output promises and concerns about upfront fee structure.Solar.com's composite of published customer feedback, not a customer quote

Thorough, clear early conversations. Positive reviews say the initial meeting and proposal process were well explained and detailed, which helped set expectations for the project. Representative review excerpt: "The initial meeting was very thorough and carefully explained."

Trust-building consultation. Some reviewers say the company took time to inspect the home and provide a careful assessment before moving forward. Representative review excerpt: "As a recently new homeowner I needed to find a company that I could trust to inspect my roof for any damages leading into the rainy season."

Expectation gaps in sales promises. Complaint reviews describe cases where the sales conversation did not match later results, especially around system output and contract expectations. Representative review excerpt: "We were told by Robert at the time of purchase that the amount of panels that we purchased would generate enough power to power our home and additional dwelling unit."

Price & financing transparency

Price Transparency5.4/10

Feedback on pricing and financing is mixed and leans negative. Some reviewers say costs, financing, and rebate timing were explained adequately, while others report confusion about final charges, deposits, or what was included in the agreement.Solar.com's composite of published customer feedback, not a customer quote

Some clarity on payment timing. A few reviewers say they were able to confirm whether additional payment was needed and felt the process was handled clearly enough. Representative review excerpt: "I did contact the office to clarify if additional payment was necessary as the solar re-installation had not yet taken place at the time I wrote the final check."

Financing and rebate framing. Some positive feedback says financing and rebate timing were explained in a way that made the monthly cost feel manageable. Representative review excerpt: "We decided to invest in solar since the financing costs coming back (after the solar rebate) we're adding up to the same we paid monthly for our electric bill alone-..."

Frequent cost and deposit concerns. Complaint reviews mention surprise-cost concerns, unmet pricing expectations, and frustration when schedules or reimbursements did not move as expected. Representative review excerpt: "We redid the driveway before we received payment through insurance as we didn't trust that it would be handled in a timely manner after their unresponsiveness."

Communication & coordination

Communication5.8/10

Reviews show a split picture on communication and coordination. Many customers describe responsive office contact and clear follow-up, but a substantial set of complaints says calls and emails went unanswered or handoffs between teams broke down.Solar.com's composite of published customer feedback, not a customer quote

Responsive follow-up for many projects. Positive reviews say the team stayed in touch by email, phone, and quick callbacks, which helped keep the project moving. Representative review excerpt: "This was clearly & efficiently communicated via email & in a follow up phone call."

Named contacts and quick contact. Some reviewers say they had clear go-to people and received fast responses even outside normal hours. Representative review excerpt: "I had a really good experience from Preman Roofing, Robert and Ian were my go to people."

Unanswered messages and coordination gaps. Complaint reviews describe missed calls, ignored emails, and uncertainty about who was responsible for next steps. Representative review excerpt: "They completely ignored my emails and calls, just as mentioned in another posted review."

Timeline reliability

Timeline Reliability6.1/10

Timing feedback is mixed. Many reviewers say projects were completed on schedule or even quickly, but others report long delays, rescheduling, or confusion around appointment dates and project sequencing.Solar.com's composite of published customer feedback, not a customer quote

Fast completion on some jobs. Positive reviews say some projects moved quickly and were completed in a short window once work began. Representative review excerpt: "The team at Preman had a competitive bid, they were communicative, and had all the work done in under 2 days!"

On-time delivery for some installations. Several customers report that installation and related work were finished on time with solid execution. Representative review excerpt: "Installation done on time and materials and workmanship outstanding!"

Delays and schedule changes. Complaint reviews describe late starts, shifted dates, and in some cases significant delays relative to the original timeline. Representative review excerpt: "Preman was nearly a year late in meeting their estimated timeline for installing solar on my office building."

Workmanship & site care

Workmanship7.1/10

Workmanship is one of the stronger parts of the review set. Reviewers often praise the quality of the roof work, crew professionalism, and cleanup, though a smaller set of complaints mentions damage, unfinished details, or poor protection of the site.Solar.com's composite of published customer feedback, not a customer quote

Strong installation quality. Many reviewers describe the workmanship as outstanding and say the finished roof looked great. Representative review excerpt: "Installation done on time and materials and workmanship outstanding!"

Professional crews and cleanup. Several positive reviews mention careful cleanup, solid repairs, and crews that handled complex work well. Representative review excerpt: "There was a bit of lack of coordination between the roofing people and the electrical people, but that was due to the complexity of the wiring and they worked it..."

Site damage and unfinished details. Complaint reviews mention concerns about damage during the job or installation details that were not handled to expectation. Representative review excerpt: "Not to mention the gaping hole the removal of the ducting left in my "roof" which left wide open spaces right into my upstairs hallway that any serial killer could..."

Long-term support & performance

Long-Term Support6.5/10

Post-install support draws both praise and criticism. Some reviewers report fast repair visits and helpful follow-up even years later, while others say warranty work, paperwork, or repair completion took too long or remained unresolved.Solar.com's composite of published customer feedback, not a customer quote

Helpful follow-up repairs. Positive reviews say the company returned for touch-up work or repair visits and responded quickly when contacted. Representative review excerpt: "4 years after they did a great roofing job on our house they came out and did a small touch up repair free and within a few days."

Accessible after installation. Some customers describe staff who stayed available for questions and evening or weekend support. Representative review excerpt: "He is one of those people that makes himself available at night and on the weekends and is very knowledgeable about roofing systems."

Warranty delays and unfinished service. Complaint reviews say some warranty repairs or final paperwork took much longer than expected, and in some cases work was still not completed. Representative review excerpt: "The roof replacement and solar install went well however, we started a warranty repair in Aug 2023 and have yet to have the work completed properly."

Bottom line: PREMAN ROOFING AND SOLAR’s review profile is strongest on workmanship and generally solid on sales clarity, but it is more uneven on pricing, communication, and post-install support. The overall score reflects a company that receives a lot of praise for the quality of the finished work, while a meaningful share of reviewers report issues with follow-up, timing, and transparency.

Important context: this chart shows investor-owned-utility records only. Companies that shift work toward municipal-utility territory (LADWP and city power departments) or other states will show declining bars here even while building steadily elsewhere, and 2025-26 records also lag real installation dates. Treat this as a partial window, not the company's full trajectory.

How we built this data

Methodology: Counts are residential PV interconnections in investor-owned-utility territory (PG&E, SCE, SDG&E) per CPUC Rule 21 public records through May 2026. Postal and name variants are merged. Municipal utility territory such as LADWP, Glendale, Pasadena, Burbank, Anaheim, and Riverside Public Utilities is not included in those CPUC counts. Counts show recorded installations, not quality ratings. Reported costs are self-reported on owned-system interconnections. No installer can pay for placement.

Who we are: Solar.com is a solar marketplace — we connect homeowners with installers and earn a fee when projects move forward. These rankings and scores are computed from public installation records and published customer reviews. No installer can pay for placement, and no installer — including those we work with — can pay to change a score.
