How does Century Roof 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.

Where Century Roof and Solar builds

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.

Century Roof 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 Integrity7.8/10

Reviews mostly describe a clear, professional sales process with helpful explanations of roof conditions, scope, and expected outcomes. The main complaint pattern is around delayed or missing quotes, occasional estimate fees, and a few concerns about how problems or pricing were presented.Solar.com's composite of published customer feedback, not a customer quote

Clear, helpful explanations. Reviewers frequently say the team explained problems, options, and expected work in a way that made them feel confident from start to finish. Representative review excerpt: "Tony would call me and give me updates and explain things to me so I felt confident from start to finish."

Professional and detail-oriented proposals. Several reviewers describe thoughtful, meticulous assessments and say the team took time to explain immediate issues and concerns before work began. Representative review excerpt: "They were professional, arrived on time, explained immediate problems and other concerning issues."

Quote delays and estimate concerns. Some reviewers report waiting weeks or longer for a quote, and a few mention estimate fees or questions about how a problem or price was determined. Representative review excerpt: "It has been over 6 month and multiple text message but never received quote in my roof and solar work."

Price & financing transparency

Price Transparency7.0/10

Feedback on pricing is generally positive, with many reviewers saying expectations were clear and billing was handled straightforwardly. At the same time, some reviews describe higher-than-expected pricing, estimate or service fees, and occasional confusion around what was included in the scope.Solar.com's composite of published customer feedback, not a customer quote

Clear pricing expectations. Reviewers often say pricing, billing, and scope were explained clearly before work moved forward, which reduced surprises. Representative review excerpt: "Clear communication and expectations from the first phone call, clear pricing, timeline, and billing."

Transparent about added costs. Some customers report being told upfront when additional costs could apply, and a few say the company handled a pricing issue in a customer-friendly way. Representative review excerpt: "Tony stepped in and did the right thing, absorbing the cost rather than billing us for it — that says a lot about how this company operates."

Fees and higher quotes. A smaller group of reviewers mentions estimate or service fees and says the price felt high, even when they felt the work quality justified it. Representative review excerpt: "When I called to get a roof estimate, they said they now charge $150 estimate fee."

Communication & coordination

Communication7.6/10

Most reviews describe responsive communication, timely updates, and a team that kept customers informed through the project. The complaint pattern is concentrated around slow callbacks, missed follow-through on appointments, and occasional difficulty getting scheduled.Solar.com's composite of published customer feedback, not a customer quote

Frequent updates. Reviewers commonly say they received regular updates and clear explanations, often from the owner or office staff, which helped the project feel organized. Representative review excerpt: "Tony would call me and give me updates and explain things to me so I felt confident from start to finish."

Friendly office coordination. Customers also describe office staff as helpful and timely in keeping them updated on what needed to happen next. Representative review excerpt: "We also appreciated those in the office for keeping us updated with what had to be done in a friendly and timely manner."

Slow follow-through for some requests. A few reviewers report having to make repeated calls or wait longer than expected for callbacks, appointments, or next-step communication. Representative review excerpt: "It took 3 calls with the office with promises of a call back to schedule a roof inspection."

Timeline reliability

Timeline Reliability7.4/10

Timeline feedback is mostly positive, with many reviewers saying crews arrived on time and projects moved at a reasonable pace once underway. The main criticism is that a few customers experienced delays in estimates, scheduling, or completion, especially when extra work or follow-up was involved.Solar.com's composite of published customer feedback, not a customer quote

On-time crews and realistic schedules. Several reviewers say the team arrived as scheduled, explained the timeline clearly, and set realistic expectations before work started. Representative review excerpt: "The representative provided a detailed explanation of the replacements options, a breakdown of all costs and a realistic timeline for installation."

Permitting and installation handled smoothly. Some customers note that the company managed permitting and installation as part of the process, which helped keep the job moving. Representative review excerpt: "They did the permitting and Installation."

Scheduling delays for a minority of reviews. A few reviewers report waiting longer than promised for estimates, inspections, or completion, even after follow-up calls. Representative review excerpt: "It took 3 calls with the office with promises of a call back to schedule a roof inspection."

Workmanship & site care

Workmanship9.4/10

This is the strongest area in the review set. Reviewers overwhelmingly describe high-quality workmanship, careful crews, thorough cleanup, and respectful treatment of the property, with only a small number of complaints about debris, leaks, or scope issues.Solar.com's composite of published customer feedback, not a customer quote

Strong finished quality. Reviewers frequently say the finished roof or repair work looked excellent and showed attention to detail. Representative review excerpt: "The finished product is beautiful, and I could tell they paid attention to the details - couldn't be happier."

Careful cleanup and property respect. Many customers mention thorough daily cleanup and respectful crews who took care around landscaping and the home. Representative review excerpt: "The workers were incredibly respectful of my property and cleaned up thoroughly every single day (I didn't find a single stray nail!)."

A few workmanship complaints. A small number of reviews describe leaks, debris, or concerns about whether the full scope was included in the estimate or later work. Representative review excerpt: "They replaced our roof in 2019 branch (NALC) it started leaking in 2025 and caused damages to our office."

Long-term support & performance

Long-Term Support7.2/10

Post-install feedback is generally favorable, with some reviewers saying the team stayed helpful after completion by explaining warranty steps and following up proactively. Still, the complaint pattern includes reports of delayed repair follow-up, recurring leak concerns, and questions about warranty coverage or long-term service responsiveness.Solar.com's composite of published customer feedback, not a customer quote

Helpful warranty guidance. Some reviewers say the company provided step-by-step warranty instructions and useful follow-up information after the job was finished. Representative review excerpt: "Gave us instructions step by step (with a video even) on how to transfer the warranty to the new company and what steps to take to protect our investment."

Proactive follow-up after install. Reviewers also describe the team reaching out with status updates and next steps instead of waiting for customers to chase them down. Representative review excerpt: "Instead of waiting for us to call and ask what to do, Tony Diaz reached out to us before we even thought of it with information on the status of..."

Repair follow-up gaps. A few customers report difficulty getting post-install repair appointments or describe recurring issues that were not resolved to their satisfaction. Representative review excerpt: "They acknowledge the correspondence but never get in touch with an appointment for the repair I am willing to pay."

Bottom line: Century Roof and Solar’s review profile is strongest on workmanship and site care, with most customers describing careful crews, thorough cleanup, and solid finished results. Sales, communication, timeline, pricing, and post-install support are generally positive but show a recurring minority of complaints around quote delays, scheduling, fees, and repair follow-through.

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.
