An exploratory look at nine roofing and home service company reports in the San Francisco Bay Area.
A five-star rating is easy to understand. It tells you customers have reported positive experiences with a company.
What it doesn't tell you is how many customers contributed, where the reviews came from or how much additional information is available about the business.
To see how those details can change the picture, we examined nine publicly accessible ONE AllRatings company reports associated with roofing services in the San Francisco Bay Area.
We compared the displayed Star Score, TOTAL SCORE, review count, number of sources and supporting company information.
This was a small, deliberately selected sample intended to demonstrate differences between rating measures. It was not a random sample or an estimate of how all roofing companies perform.
What We Examined
The nine reports contained a combined 366 displayed reviews and 22 summed review-source counts.
The source count represents the total of the Sources fields across the nine reports. It does not mean 22 different review websites were represented.
The reported TOTAL SCORES ranged from 67.2 to 100 on OAR's 100-point scale.
The most interesting difference appeared among businesses with identical displayed star ratings.
Finding 1: Five Stars Didn't Always Mean the Same TOTAL SCORE
Three businesses in our sample displayed five stars.
Their TOTAL SCORES were not identical.
| Company | Stars | Reviews | Sources | TOTAL SCORE |
|---|---|---|---|---|
| J.O Roofing Inc. | 5.0 | 48 | 3 | 100 |
| All Bay Roofing | 5.0 | 6 | 2 | 80 |
| Crowson Roofing | 5.0 | 4 | 2 | 80 |
All three companies displayed five stars, but the range in TOTAL SCORE was 20 points.
That difference reflects how OAR calculates its overall rating.
Customer reviews represent 80% of TOTAL SCORE. Key Docs verification and company report disclosures each contribute another 10%.
The All Bay Roofing and Crowson Roofing reports showed 0% in the Key Docs and Report fields in the available snapshots. J.O Roofing displayed 100% in both.
A missing verified-document score does not establish that a business lacks legally required credentials. It indicates the verification status shown by OAR.
The comparison demonstrates why a five-star rating and an overall business assessment are not interchangeable.
Finding 2: More Reviews Didn't Guarantee a Higher Score
The review counts varied considerably across the sample.
Dynasty Roofing Inc. displayed 109 reviews, a 4.5-star rating and a TOTAL SCORE of 72.5.
J.O Roofing Inc. displayed 48 reviews, five stars and a TOTAL SCORE of 100.
These two examples do not establish a relationship between review volume and business quality. They show that review count alone doesn't determine OAR's overall rating.
Review volume is useful context, but consumers still need to examine the feedback and other information contributing to a company's assessment.
Finding 3: The Highest TOTAL SCORES Included More Than Customer Ratings
Three sampled reports displayed TOTAL SCORES of at least 90.
J.O Roofing Inc. displayed 100.
South Creek Roofing displayed 98.2.
Longshore Handyman, which is listed in several contractor categories including roofing, displayed 94.
All three reports also showed 100% for Key Docs and Report information.
This is consistent with OAR's published scoring framework, in which verified documents and company disclosures contribute to TOTAL SCORE.
A score of at least 90 is necessary for OAR's highest certification level, but certification also requires additional checks. A qualifying number alone does not establish certification status.
Finding 4: A Single Number Is Only the Beginning
OAR presents several fields alongside TOTAL SCORE because they answer different questions.
The Star Score summarizes customer ratings using OAR's published methodology.
The Sources field shows how many review websites contributed to the calculation.
The Reviews field shows how many customer reviews were analyzed.
Key Docs represents applicable verified documentation, while Report measures available company disclosure information.
Consumers can use these fields to decide what to investigate further.
For example, a business with an excellent star rating but limited verified documentation might deserve additional credential checks.
A company with a modest number of reviews may still be worth considering, but a homeowner may want recent references before signing a contract.
The rating information is most helpful when it guides additional research.
Study Methodology
This exploratory analysis was assembled on October 9, 2026, from publicly accessible ONE AllRatings company-report content.
Nine distinct businesses classified as roofing contractors, including one multi-service contractor, were selected from San Francisco Bay Area reports.
The sample was chosen to illustrate variations in publicly displayed scores and supporting information, not to produce a statistically representative survey.
For each company, we recorded the displayed:
- Star Score
- TOTAL SCORE
- Number of review sources
- Number of reviews
- Key Docs percentage
- Report percentage
We compared the published values without recalculating OAR's proprietary review-level weighting.
We did not obtain individual review records, verify the original third-party reviews, or independently confirm each business's licenses and insurance.
Limitations
The findings should be interpreted within the limits of the available information.
Nine company reports are too few to describe the roofing industry or local businesses nationally.
The sample was not randomly selected. It also focuses on one service category and one geographic region.
Publicly displayed scores can change when new reviews, documentation or company information are processed. Some available source snapshots may not reflect the latest production values.
We did not examine whether the same review sources were represented for every company or independently validate the underlying scoring data.
For these reasons, the results describe differences within the selected reports. They do not establish the prevalence of those differences across the full ONE AllRatings database.
What Consumers Can Take Away
Five stars can be a useful starting point when researching a company, but the score alone leaves important questions unanswered.
The selected reports illustrate how businesses with identical star ratings can have different review counts, different levels of documentation and different TOTAL SCORES.
Before hiring a company, consider the complete record. Look at recent customer feedback, compare multiple sources, check credentials and review the details of the service being offered.
ONE AllRatings organizes much of that information into individual reports, allowing consumers to see more than a single star average.
The better you understand the information behind a rating, the better prepared you'll be to choose a company that fits your needs.
