Short answer: As of September 2026, the five highest-scoring roofing contractors in the San Francisco-Oakland-Fremont, CA metro on The Roofing Brief Contractor Score are NC Roofing Solution, Inc. (90.0), Epic Roof Replacement (77.9), Saber Roofing, Inc. (76.1), Mr. Roofing, Inc. (74.3), Moctezuma Roofing, Inc. (74.1). Each holds a certification we verified on the manufacturer’s own register, every rating was corroborated elsewhere, and placement on this page is not for sale.
The Roofing Brief scored 12 certified roofing contractors serving the San Francisco metro on a published, reproducible formula, then researched each of the top five individually to confirm its record. San Francisco recorded no damaging hail at all in the past decade, the only metro in this batch with a clean zero. Bay Area roofs fail from sustained winter rain, wind-driven water at flashing details, and ultraviolet degradation on the flat and low-slope decks that dominate the older housing stock. California requires a Contractors State License Board licence under the C-39 classification for any roofing job over $500, backed by a trade exam, a law and business exam, and four years of documented journey-level experience, so the CSLB record is the first thing to check here.
Why a San Francisco roof fails slowly rather than suddenly
San Francisco has effectively no severe-weather risk to a roof and a great deal of water. The ten-year record contains 61 hail reports, none reaching an inch, no tornadoes, and 28 severe wind reports, the strongest a 97 mph gust measured at Pacifica on 14 December 2024. What ages a roof here is wind-driven winter rain, salt air and fog, arriving mostly between December and March. That pattern rewards spending on underlayment, flashing details and drainage rather than on impact-rated coverings, and it makes autumn the sensible season to book work.
The city’s flat roofs are the main event. San Francisco sits in Climate Zone 3, which falls outside the prescriptive cool roof requirements for re-roofing: those apply to steep-slope single-family roofs in Zones 4 and 8 to 15, and to low-slope ones in Zones 4 and 6 to 15. So the reflectance rules that drive product choice in Sacramento or Riverside do not bind here, on either roof type. If your building is a mix of the two, which is common here, ask the contractor to state which rule applies to which section before the permit application goes in.
One rule causes recurring confusion. San Francisco’s Better Roofs Ordinance, in force since 2017, requires solar or a living roof on 15 to 30 per cent of the roof area of most new buildings of ten storeys or fewer. It applies to new construction, not to replacing the roof on an existing home. A contractor who tells you a re-roof triggers a solar mandate is mistaken. Re-roofing permits themselves are routine: the Department of Building Inspection issues many of them over the counter, and torch-applied work may also need a fire department operational permit.
California licenses roofing properly as Class C-39, requiring four years of journey-level experience and two examinations, and the CSLB record shows bond, insurance and disciplinary history for every number. In a market this expensive, the other protection worth knowing is financial: on a home improvement contract the down payment cannot exceed $1,000 or 10 per cent of the price, whichever is less, and progress payments must track work actually completed. A contractor asking for half up front is telling you something useful about how they run their business.

- BuildZoom score 111, in the top 4% of 336,931 licensed California contractors, with at least 310 permitted projects in the past three years. BuildZoom
- BBB business profile with customer reviews on record. BBB
What they actually do. Residential and commercial roofing and repair across the East Bay and wider Bay Area.
Why it ranks here. 310 permitted projects in three years is the highest verified permit volume in the San Francisco pool, drawn from public building records rather than self-reported figures.
Best fit for: East Bay homeowners from Walnut Creek through Concord and Danville.
What we would want clarified. BBB reviews are mixed. One complaint describes an unauthorised $1,400 permit charge not stated in the original contract. Insist that permit fees are itemised in the written contract before signing. We publish this because a ranking that only prints the flattering findings is an advertisement, not an assessment.
Verify the certification yourself on the GAF registry listing. The number carried on that listing is (925) 477-2993, which is the registry’s contact line and is often a directory tracking number rather than the contractor’s own: take the number from the company’s own website and compare the two.
2. Epic Roof Replacement — TRB Score 77.9
Epic Roof Replacement is based in San Leandro, CA, and holds Master Elite standing on the GAF certification registry.
Certifications held: Master Elite (GAF), Owens Corning Preferred Contractor. Certification by more than one manufacturer is uncommon and requires meeting each programme’s separate standards for insurance, training and track record.

What they actually do. Roof replacement, repair and new roof installation across the East Bay.
Why it ranks here. Dual-certified by GAF and Owens Corning, and one of the few contractors in this batch verifiable directly on a second manufacturer’s own public directory rather than only through its own marketing.
Best fit for: East Bay homeowners wanting warranty options from two manufacturers.
What we would want clarified. No BBB rating or accreditation was locatable, and the specific CSLB licence number was not published on the sources we could reach. Ask for the licence number and verify it at cslb.ca.gov before signing. We publish this because a ranking that only prints the flattering findings is an advertisement, not an assessment.

What they actually do. Residential roof systems across the Peninsula, from Woodside through Palo Alto and Redwood City.
Why it ranks here. 1,679 permitted projects is by a wide margin the largest verified permit history in the San Francisco pool, and 46 years of second-generation family ownership with 15 full-time employees rather than subcontracted crews is a meaningful distinction in this trade.
Best fit for: Peninsula homeowners, and anyone who wants employed crews rather than subcontractors.

28 severe weather reports in a decade, and why that matters in San Francisco
Aggregate hail counts tell you very little about a specific roof. These are the individual events: every severe-weather report logged by the National Weather Service across the 5 counties of the San Francisco-Oakland-Fremont, CA statistical area over ten years, with the dates, the stone sizes and the towns they landed on. Over that decade the metro logged 61 hail reports, 28 severe thunderstorm and high wind reports and 0 tornadoes. Reported property damage from hail, severe wind and tornado over that decade totalled $5.0 million; flood and winter-storm losses are counted separately and are not included.
The biggest hail to fall on San Francisco in a decade
| Date | Stone size | Reported near | County |
|---|---|---|---|
| 3 March 2018 | 0.5 in | Concord | Contra Costa |
| 29 November 2018 | 0.5 in | San Francisco | San Francisco |
| 2 March 2018 | 0.25 in | Oakland | Alameda |
| 2 March 2018 | 0.25 in | Bolinas | Marin |
| 2 March 2018 | 0.25 in | Berkeley | Alameda |
| 2 March 2018 | 0.25 in | Berkeley | Alameda |
The largest stone on record for this metro fell on 3 March 2018 near Concord, measured at 0.5 inches. That is below the size at which hail normally damages a shingle roof.
Wind. The strongest thunderstorm gust logged in the metro was 84 knots, about 97 mph, near Sharp Park on 14 December 2024. Asphalt shingles begin lifting at roughly 67 mph when they are correctly nailed, and considerably below that when they are not.
What the National Weather Service wrote about it
The NWS logs a written account of each severe-weather episode. This is its description of the 13 October 2025 event near Butano Park, reproduced verbatim:
A strong thunderstorm cell touched down just south of Ano Nuevo State Park at 4:23 PM. Video from a farm near the location showed damage to structures, sparking speculation of a possible tornado. Subsequently, an NWS team conducted a storm survey at the site. The team identified damage consistent with straight line winds. Damage was noted from the coast, just south of A��o Nuevo State Park, eastward about 3/4 of a mile. This damage included, but not limited to, a hoop house visqueen cover being torn off, structural damage to two hoop houses, a large water storage tank being transported over a 1/4 mile, and moderately large diameter coastal cypress trees being snapped. There was one item…
That is what the specification has to anticipate here, written up by the agency that recorded it rather than by a contractor selling the repair.
When it happens. Severe weather reports cluster in March (27), January (19), April (12). The worst years on record were 2018 (32), 2017 (12), 2020 (12). If you are scheduling non-urgent work in San Francisco, the months outside that window are when crews are least stretched and least likely to be triaging emergency callouts ahead of your job.
Source: NOAA National Centers for Environmental Information, Storm Events Database, county-level detail files 2016 to 2025, filtered to the counties of this statistical area by The Roofing Brief. Damage figures are as reported to the NWS and undercount insured losses.
What to do with this. Hail is not the governing risk in San Francisco. Weight your decision toward wind rating, ventilation and flashing detail rather than paying extra for impact-rated shingles.
How to check a San Francisco roofer in ten minutes
Licensing is required in CA. California requires a Contractors State License Board licence for any job where labour and materials combined reach $1,000 or more, a threshold raised from $500 by Assembly Bill 2622 on 1 January 2025. The exemption never covers a reroof, because the Board treats any work that needs a permit as requiring a licence whatever its value. Roofing is the C-39 classification; a B General Building licence can also cover it.
A C-39 qualifier must document at least four years of journey-level experience and pass both a trade examination and a law and business examination. Every active licence carries a $25,000 contractor’s bond, and C-39 roofing licensees must carry workers’ compensation whether or not they have employees: roofing is one of the few classifications that cannot file the no-employee exemption.
Check here: CSLB Check a License. The CSLB record also shows complaint and disciplinary history, including citations and accusations. Treat any status other than Active as disqualifying.
Four checks to run before you sign anything, in any state.
- Verify certification at the source. Use the GAF verification tool rather than trusting a badge image on a company website.
- Get the certificate of insurance from the insurer, not the contractor, and confirm general liability and workers compensation are both active on the day work starts.
- Confirm who pulls the permit. If a contractor asks you to pull it as the homeowner, that moves liability onto you. Decline.
- Get warranty terms in writing before any deposit, and check the manufacturer warranty being promised actually requires the certification tier the contractor holds.
The shape of the San Francisco contractor market

How these San Francisco rankings were produced
Every contractor in the San Francisco-Oakland-Fremont, CA pool was scored out of 100 on four published components: certification tier, a Bayesian adjusted rating, review depth and distance from the metro centre. In this metro that meant scoring 12 certified contractors, of whom 1 hold President’s Club standing and 11 Master Elite, against a metro mean rating of 4.833. The top five were then researched individually against Better Business Bureau records, state licence registers and manufacturer directories. The findings are printed above whether they flatter the contractor or not, and nobody paid to appear.
The full method, the weightings, what the GAF certification tiers actually mean, who is eligible to be ranked and what we do not claim are all set out on our roofer ranking methodology page.

What was the worst hailstorm in San Francisco in the last ten years?
The largest hailstone logged by the National Weather Service in the San Francisco-Oakland-Fremont, CA statistical area between 2016 and 2025 measured 0.5 inches, reported near Concord on 3 March 2018.

When is the worst time of year for roof damage in San Francisco?
Severe-weather reports in the San Francisco-Oakland-Fremont, CA statistical area cluster in March, January, April, on the NOAA record for 2016 to 2025. If the work can wait, booking outside that window usually buys you shorter lead times and more of the contractor’s attention.
Do roofers need a licence in CA?
California requires a Contractors State License Board licence for any job where labour and materials combined reach $1,000 or more, a threshold raised from $500 by Assembly Bill 2622 on 1 January 2025. The exemption never covers a reroof, because the Board treats any work that needs a permit as requiring a licence whatever its value. Roofing is the C-39 classification; a B General Building licence can also cover it. A C-39 qualifier must document at least four years of journey-level experience and pass both a trade examination and a law and business examination. Every active licence carries a $25,000 contractor’s bond, and C-39 roofing licensees must carry workers’ compensation whether or not they have employees: roofing is one of the few classifications that cannot file the no-employee exemption.
What should I check before hiring a roofer in San Francisco?
The CSLB record also shows complaint and disciplinary history, including citations and accusations. Treat any status other than Active as disqualifying.
Is San Francisco a hard market to find a good roofer in?
San Francisco recorded no damaging hail at all in the past decade, the only metro in this batch with a clean zero. Bay Area roofs fail from sustained winter rain, wind-driven water at flashing details, and ultraviolet degradation on the flat and low-slope decks that dominate the older housing stock. California requires a Contractors State License Board licence under the C-39 classification for any roofing job over $500, backed by a trade exam, a law and business exam, and four years of documented journey-level experience, so the CSLB record is the first thing to check here.
Is wind or hail the bigger risk to a roof in San Francisco?
Wind, by a wide margin. The San Francisco-Oakland-Fremont, CA statistical area logged 28 severe thunderstorm and high wind reports against 0 hail reports of an inch or more between 2016 and 2025. Wind damage shows up at the rake, ridge and edge rather than across the field of the roof, so the fastening schedule and edge detail matter more here than the impact rating of the shingle.
