How does Mccormack Roofing 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 Mccormack Roofing 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.

Mccormack Roofing 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

Reviews of the sales and proposal process lean positive overall, with many reviewers saying the company explained options clearly, stayed honest about pricing, and set out changes and recommendations in a straightforward way. At the same time, a meaningful minority describe pressure, broken promises, and gaps between what was discussed and what they felt was delivered.Solar.com's composite of published customer feedback, not a customer quote

Clear explanations. Several reviewers say the sales process was thorough and easy to follow, with the team taking time to explain options, the process, and roof details. Representative review excerpt: "The salesman spent at least an hour explaining all my options and the process and did a thorough inspection of the roof."

Straightforward pricing. Some customers report that the company kept them informed and was honest with the price, which helped the process feel manageable. Representative review excerpt: "They keep you informed of the progress and honest with the price."

Pressure and expectation gaps. Other reviewers describe feeling misled or pressured, including concerns about promises that were not kept and expectations that did not match the final work. Representative review excerpt: "Company has some descent employees and I was on my way to recommending them but experience ruined by dishonest salesman who didn't want to come through on his end of..."

Price & financing transparency

Price Transparency5.0/10

Feedback on pricing and financing is mixed to negative, with more complaints than praise in this category. Positive reviews mention fair pricing and clear communication, but many reviewers raise concerns about deposits, final billing, refunds, delayed follow-up, and incentive timing.Solar.com's composite of published customer feedback, not a customer quote

Deposits, final payment, and timing concerns. Other reviewers describe problems around money handling, including delayed follow-up on billing or bids, cancellation issues, and frustration tied to final payment or incentive timing. Representative review excerpt: "All they had to do was call for an inspection for the next day and then collect the final check literally the next day, but they said they won't call..."

Fair pricing experiences. Some reviewers say the pricing felt fair and that the company was upfront about costs during the project. Representative review excerpt: "Not McCormack, they did their job for a fair price."

Price clarity when updates were provided. A few customers report being kept informed and told the price honestly, which made the financial side feel more transparent. Representative review excerpt: "They keep you informed of the progress and honest with the price."

Communication & coordination

Communication5.6/10

Communication and coordination receive a mixed review pattern. Many customers describe clear updates, smooth handoffs, and steady follow-through, but a substantial group reports no-shows, missed callbacks, and difficulty getting answers as projects moved forward.Solar.com's composite of published customer feedback, not a customer quote

Clear project updates. Several reviewers say the company communicated clearly from planning through close-out and followed through on commitments. Representative review excerpt: "From planning to installation and final close-out, the company communicated clearly and followed through on their commitments."

Smooth handoffs. Others describe the process as smooth across the sales, project management, and office teams, with progress updates along the way. Representative review excerpt: "The process was very smooth from the sales, to project manager to office help."

Missed follow-up and no-shows. Reviewers also report unanswered emails, appointment no-shows, and difficulty reaching someone who could take ownership of the project. Representative review excerpt: "I even tried calling the main line to get someone different, which seemed to work, but the rep never showed up for the appointment."

Timeline reliability

Timeline Reliability5.4/10

Timeline reliability is a common pain point, even though some projects finished on schedule or with permit and utility coordination handled for the customer. Reviewers also describe long delays, permit and inspection setbacks, and projects that took much longer than expected before completion or activation.Solar.com's composite of published customer feedback, not a customer quote

Some jobs finished on time. A number of reviewers say work began on time, moved smoothly, and in some cases finished ahead of schedule. Representative review excerpt: "Once the installation began, the process went very smooth and was completed a day ahead of schedule."

Permit and utility handling. Some customers report that the company managed county permit requirements and utility-related steps for them. Representative review excerpt: "McCormack handled all of the county permit requirements as well as dealing with the utility company to update my utility customer status as an energy producer."

Delays and scheduling setbacks. Other reviewers describe long waits, missed dates, and delays tied to permitting or inspection steps, including projects that stretched far past the original schedule. Representative review excerpt: "Unorganized, didn't return calls, we were told our roof would be replaced in June - didn't get done until the end of October."

Workmanship & site care

Workmanship7.4/10

Workmanship and site care are a relative strength in the review set. Most reviewers describe professional crews, solid installation quality, and good cleanup, though a smaller group reports debris left behind, missed details, or unfinished cleanup after the job.Solar.com's composite of published customer feedback, not a customer quote

Professional crews. Many reviewers praise the installation crews for being on time, hard-working, friendly, and easy to communicate with. Representative review excerpt: "Installation crew was on time, worked hard, cleaned up afterwards, was friendly, and was easy to communicate with."

Strong install quality. Other customers describe the completed work as solid and say they were pleased with how the project turned out. Representative review excerpt: "Overall, I am very pleased with how the project turned out and would recommend McCormack Roofing to homeowners in Irvine and the surrounding Orange County area who are considering a..."

Cleanup and site issues. Some reviewers report leftover debris or cleanup problems after installation, suggesting that site care was not always consistent. Representative review excerpt: "I had since discovered in the attic extreme debris that was left up there when the roof was installed by McCormack."

Long-term support & performance

Long-Term Support6.4/10

Post-install support and performance are generally positive but not uniformly so. Reviewers mention completed utility updates, reasonable project wrap-up, and durable roof or system performance, while others describe frustration with warranty response, monitoring, or unresolved follow-up after installation.Solar.com's composite of published customer feedback, not a customer quote

Completed post-install steps. Some reviewers say the company handled utility-related updates and other close-out steps after installation. Representative review excerpt: "McCormack handled all of the county permit requirements as well as dealing with the utility company to update my utility customer status as an energy producer."

Durability and follow-through. A few customers report long-term satisfaction with roof performance and say the work held up well over time. Representative review excerpt: "McCormack Roofing installed the steel roof for my house in 2010 and it was warranted for 10 years."

Warranty and monitoring concerns. Other reviewers describe difficulty getting post-install help, including warranty concerns, monitoring issues, or unresolved problems after the project ended. Representative review excerpt: "Long story short I installed my own third-party monitoring system and figure out their install problem."

Bottom line: MCCORMACK ROOFING’s reviews are strongest on workmanship and site care, while communication, pricing transparency, and timeline reliability are more uneven. Customers often praise clear explanations and solid crews, but a notable share report delays, coordination problems, and issues around billing or post-install support.

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.
