Short answer: As of September 2026, the five highest-scoring roofing contractors in the Stockton-Lodi, CA metro on The Roofing Brief Contractor Score are Phoenix Roofing Co, Inc., trading as Phoenix Roofing & Solar (80.4), Davis Roofing Group (75.2), American Array Solar and Roofing (69.7), Baker Roofing Co. (69.4), Pruden Roofing (68.5). Each is certified by a manufacturer whose register we checked by hand, each rating has been tested against a source outside that register, and nobody bought a place on this page.
The Roofing Brief scored 11 certified roofing contractors serving the Stockton metro on a published, reproducible formula, then researched each of the top five individually to confirm its record. Stockton has one of the flattest certified pools in this programme. First place scores 80.4 and fifth 68.5, with no President’s Club contractor anywhere in the metro: every one of the five below is Master Elite. That is unusual. It means the Northern San Joaquin Valley has plenty of qualified roofers and no standout, so the decision genuinely turns on proximity and quote quality rather than on tier. California’s C-39 licence does the heavy lifting: four years of journey-level experience, two exams, and a CSLB record that publishes complaint and disciplinary history. Every contractor below has had its licence number checked.
The conditions a Stockton roof has to be specified for
Stockton has almost no severe-weather record at all. Across the decade NOAA holds two hail reports for San Joaquin County, both quarter-sized on 11 March 2023, one severe wind report and one brief tornado. No roof here is being specified against storms. It is being specified against heat: triple-digit summer afternoons that cycle the deck and fasteners daily, and winter tule fog and heavy dew off the Delta that keep metal wet for hours and shorten the life of flashing and sealants.
That combination makes ventilation and detailing the value in a quote. Balanced intake and exhaust keeps attic temperatures down and extends shingle life through the summer; properly lapped and sealed flashing at walls, valleys and penetrations is what survives months of morning condensation. Ask what the ventilation calculation is, not merely whether ridge vent is included.
California’s energy code does apply here in full. Stockton is in climate zone 12, where the prescriptive cool-roof requirement covers both steep-slope and low-slope re-roofing of single-family homes, so replacement products generally need certified solar reflectance and thermal emittance values unless the design uses one of the alternative compliance paths, such as extra ceiling insulation or a radiant barrier. The City of Stockton publishes its residential re-roof requirements, and San Joaquin County permits addresses outside the city.
The licence is the strongest check available in this market. Any job above $500 requires a C-39 roofing licence, which takes four years of journey-level experience and two exams, and the CSLB record shows bond, workers compensation and complaint history. That matters more than usual here because the metro has no President’s Club contractor at all: the tier cannot separate these firms, so the licence record, the review depth and the quote have to.

1. Phoenix Roofing Co, Inc., trading as Phoenix Roofing & Solar — TRB Score 80.4
Trades as Phoenix Roofing Co, Inc., trading as Phoenix Roofing & Solar; listed on the GAF registry as Phoenix Roofing Co Inc.
Phoenix Roofing Co, Inc., trading as Phoenix Roofing & Solar is based in Stockton, CA, BBB profile on record, and holds Master Elite standing on the GAF certification registry.
| Score component | Points | Max |
|---|---|---|
| Certification tier | 24 | 35 |
| Adjusted rating | 31.4 | 40 |
| Review corpus depth | 15.0 | 15 |
| Metro proximity | 10.0 | 10 |
| Total | 80.4 | 100 |
Independently corroborated:
- Holds licences 1005786, 996645, 741478 and 769328 covering General Building and Roofing, active when last checked, with a $15,000 bond through State National Insurance. CSLB
- Permit records show 530 permitted projects. BuildZoom
- BBB profile on record under both Phoenix Roofing Co, Inc. and Phoenix Roofing & Solar. BBB
What they actually do. Flat, residential and commercial roofing plus solar, across San Joaquin County.
Why it ranks here. 530 permitted projects on the public permit record is a harder number than any review count, because permits are pulled by the contractor and logged by the building department rather than solicited from customers. Active licences with a confirmed bond, and based in Stockton itself.
Best fit for: Stockton homeowners, flat and low-slope roofs, and anyone who wants the permit history checked rather than the marketing.
What we would want clarified. 121 registry reviews is a modest base, and it leads the metro by 0.1 of a point. Treat first and second here as a tie. 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 (209) 465-4377, 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. Davis Roofing Group — TRB Score 75.2
Davis Roofing Group is based in Galt, CA, BBB accredited since 25 January 2018, and holds Master Elite standing on the GAF certification registry.
Certifications held: Master Elite (GAF), Diamond Certified. Certification by more than one manufacturer is uncommon and requires meeting each programme’s separate standards for insurance, training and track record.
| Score component | Points | Max |
|---|---|---|
| Certification tier | 24 | 35 |
| Adjusted rating | 33.3 | 40 |
| Review corpus depth | 13.0 | 15 |
| Metro proximity | 5.0 | 10 |
| Total | 75.2 | 100 |
Independently corroborated:
- BBB accredited since 25 January 2018. BBB
- Holds licences 1039405 and 1026371 covering Roofing and Metal Products, active when last checked. CSLB
- Holds Diamond Certified status, which requires an independent telephone survey of a random sample of past customers rather than self-selected reviews. Diamond Certified
What they actually do. Residential roofing and metal roofing across Sacramento and northern San Joaquin counties.
Why it ranks here. Diamond Certified is the most rigorous consumer credential any contractor in this batch holds: it is awarded only after an independent researcher telephone-surveys a random sample of the company’s actual customer list, which cannot be gamed the way an open review platform can. A separate Metal Products licence classification alongside roofing is also uncommon.
Best fit for: Metal roofs, and homeowners in Galt and the northern end of the metro who want independently surveyed evidence.
What we would want clarified. Sixty-three registry reviews is a small base, and twenty miles from the metro centre. 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 (916) 900-7663, 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.
3. American Array Solar and Roofing — TRB Score 69.7
American Array Solar and Roofing is based in Livermore, CA, BBB accredited since 8 November 2023, A+ rating, and holds Master Elite standing on the GAF certification registry.
| Score component | Points | Max |

Independently corroborated:
- A+ rated and accredited since 8 November 2023, with CSLB licence 993467 on the BBB record, expiring 30 June 2028. BBB
- Independently profiled on EnergySage, a solar marketplace that vets installers. EnergySage
- Listed on Houzz with a project portfolio. Houzz
What they actually do. Solar installation and roofing, residential and commercial.
Why it ranks here. A CSLB licence number verifiable on the BBB record with an expiry running to 2028, plus independent vetting through a solar marketplace. Roof and solar from one licensed contractor avoids the warranty argument that follows when a solar installer penetrates someone else’s new roof.
Best fit for: Roof-and-solar projects.
What we would want clarified. Fifty-six registry reviews and 32 miles from the metro centre, the furthest in this top five, in Alameda County. 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 (844) 347-6527, 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.
4. Baker Roofing Co. — TRB Score 69.4
Baker Roofing Co. is based in Stockton, CA, led by Troy Baker, President, BBB profile on record, and holds Master Elite standing on the GAF certification registry.
| Score component | Points | Max |

| Certification tier | 24 | 35 |
| Adjusted rating | 25.3 | 40 |
| Review corpus depth | 10.1 | 15 |

| Total | 69.4 | 100 |
Independently corroborated:
- BBB profile on record listing Troy Baker as President, with CSLB licence 234787. BBB
- More than fifty years of commercial and residential reroofing, repair and waterproofing in Stockton. Company
What they actually do. Commercial and residential reroofing, repair and waterproofing.
Why it ranks here. A CSLB licence number in the low six figures indicates a licence issued decades ago, consistent with the fifty-year trading history, and the company is based in Stockton itself. Waterproofing alongside roofing is relevant on the flat commercial stock in this market.
Best fit for: Commercial buildings, waterproofing, and Stockton homeowners wanting the oldest licence in the metro.
What we would want clarified. At 4.4 across 24 registry reviews this is both the lowest rating and among the thinnest samples in this top five. A separate entity trading as Roofing By Baker holds licence 656571, which was inactive when last checked, so confirm you are contracting with the company holding licence 234787. We publish this because a ranking that only prints the flattering findings is an advertisement, not an assessment.

5. Pruden Roofing — TRB Score 68.5
Pruden Roofing is based in Lodi, CA, in business since 2001, BBB a+ rating, and holds Master Elite standing on the GAF certification registry.

Independently corroborated:
- A+ rated, licensed and insured. BBB
- Also listed as an Owens Corning certified roofing contractor. Owens Corning
- Locally owned and operated in Lodi since 2001, residential and commercial. Company
What they actually do. Residential and commercial roofing across Lodi and northern San Joaquin County.
Why it ranks here. Dual certification with GAF and Owens Corning, which means two manufacturers have separately vetted the same installer, and 25 years in one market. Ten miles from the metro centre.
Best fit for: Lodi and northern San Joaquin County homeowners, and anyone wanting a choice of shingle manufacturer.
What we would want clarified. At 4.5 across 39 registry reviews this is the lowest rating and among the thinnest samples in this top five, against a metro mean of 4.79. 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 (209) 471-2332, 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.
4 severe weather reports in a decade, and why that matters in Stockton
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 1 county of the Stockton-Lodi, CA statistical area over ten years, with the dates, the stone sizes and the towns they landed on. Over that decade the metro logged 2 hail reports, 1 severe thunderstorm and high wind report and 1 tornado. The database’s property-damage fields are left blank for most of these reports, so it carries no usable loss total for this metro and we do not quote one.
The biggest hail to fall on Stockton in a decade
| Date | Stone size | Reported near | County |
|---|---|---|---|
| 11 March 2023 | 1.0 in | Orford | San Joaquin |
| 11 March 2023 | 1.0 in | Stockton | San Joaquin |
The largest stone on record for this metro fell on 11 March 2023 near Orford, measured at 1.0 inches. One inch is the point at which hail starts bruising asphalt shingles, which is damage an adjuster can find even when a homeowner cannot.
Wind. The strongest thunderstorm gust logged in the metro was 61 knots, about 70 mph, near San Joaquin on 10 January 2023. Asphalt shingles begin lifting at roughly 67 mph when they are correctly nailed, and considerably below that when they are not.
Tornadoes. 1 tornado touched down in these counties over the decade.
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 11 March 2023 event near Orford, reproduced verbatim:
The public reported hail up to quarter size along Highway 26 near Beyer Lane. Photos confirmed this. The Time was estimated by radar.
That account is the design case for a roof here, and it comes from the agency that recorded it rather than by a contractor selling the repair.
When it happens. Severe weather reports cluster in March (2), April (1), January (1). The worst years on record were 2023 (3), 2022 (1). If you are scheduling non-urgent work in Stockton, 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 Stockton. Weight your decision toward wind rating, ventilation and flashing detail rather than paying extra for impact-rated shingles.
How to check a Stockton 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.
What the rest of the Stockton field looks like

How these Stockton rankings were produced
Every contractor in the Stockton-Lodi, 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 11 certified contractors, of whom 0 hold President’s Club standing and 6 Master Elite, against a metro mean rating of 4.745. The top five were then researched individually against Better Business Bureau records, state licence registers and manufacturer directories. Anything unflattering that research surfaced appears above alongside the rest, and no company bought its position.
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.

Severe-weather reports in the Stockton-Lodi, CA statistical area cluster in March, April, January, on the NOAA record for 2016 to 2025. Booking non-urgent roof work outside those months usually means shorter lead times, because local crews are not simultaneously triaging storm callouts.
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.

California’s C-39 licence does the heavy lifting: four years of journey-level experience, two exams, and a CSLB record that publishes complaint and disciplinary history. Every contractor below has had its licence number checked.
