Short answer: As of September 2026, the five highest-scoring roofing contractors in the Los Angeles-Long Beach-Anaheim, CA metro on The Roofing Brief Contractor Score are NEMA Roofing Solutions (95.0), Chandler’s Roofing (82.7), Guardian Roofs (80.4), Green Ladder Roofing (80.4), Epic Roof Replacement (76.1). All of them carry a verifiable manufacturer certification, every rating here was cross-checked against an independent record, and no money changed hands for any placement.
The Roofing Brief scored 20 certified roofing contractors serving the Los Angeles metro on a published, reproducible formula, then researched each of the top five individually to confirm its record. The Los Angeles metro’s roof risk is not in its storm record. Ten years of NOAA data for Los Angeles and Orange counties hold eight hail reports, none larger than an inch, 45 severe wind reports and $87,500 in reported damage. The defining event was fire: the Palisades and Eaton fires of January 2025 destroyed more than 16,000 structures, and in the Very High Fire Hazard Severity Zones that cover the hillsides and foothills a replacement roof must be Class A. The ranking has a clear leader. NEMA Roofing Solutions of Tarzana scores 95.0 on a perfect 5.0 across 299 reviews, 12.3 points clear of Chandler’s Roofing, a Gardena business whose roots go back to 1942. California’s C-39 licence, and the CSLB record behind every licence number, does the rest of the vetting.
What a Los Angeles roof is up against
Start with your fire zone. Chapter 7A of the California Building Code, and the City of Los Angeles’s own re-roof permit conditions, require a Class A roof covering in Very High Fire Hazard Severity Zones. The January 2025 fires, which destroyed more than 6,800 structures in and around Pacific Palisades and more than 9,400 around Altadena, turned the rebuild standard into something concrete: the whole assembly has to carry the rating, not just the visible covering, alongside ember-resistant vents and enclosed eaves. Check your address on the state’s fire hazard severity zone map before accepting a quote, because the specification and the price both change inside a zone.
In the City of Los Angeles, a straightforward re-roof with a Class A or B covering weighing under 6 pounds per square foot over solid sheathing can go through the Department of Building and Safety as an Express Permit, with no plan check. Two conditions on that permit matter. A residential replacement covering more than half the roof must use a product certified by the Cool Roof Rating Council, and removing existing tiles, installing new underlayment and resetting the same tiles is listed separately with no cool roof requirement. That second route is often the right one for the metro’s older clay and concrete tile roofs, where the tiles outlast the underlayment beneath them. Orange County cities run their own permit counters.
Weather damage arrives in winter storms rather than summer ones: February and March account for most of the metro’s severe reports, and 2024 was the busiest year. The most damaging event in the decade was an EF1 tornado in Montebello on 22 March 2023 that caused a near-total roof collapse in one industrial building and damaged 17 structures. Hail never exceeded an inch. That record argues against paying extra for impact-resistant shingles, and for spending the money on underlayment, flashing and, inside a fire zone, a correctly rated assembly.
California’s C-39 roofing licence requires four years of journey-level experience and two examinations, and every licence number can be checked on the CSLB site for bond, workers’ compensation and disclosable complaints. All five contractors below publish theirs. On a home improvement contract the down payment may not exceed $1,000 or 10 per cent of the price, whichever is less. The ranked field spans both counties, from Tarzana in the west San Fernando Valley to Orange, 29 miles from the centre, so ask about response times for warranty calls if you live at the far end of that range.

What we would want clarified. BBB’s record shows the current business starting in 2006 although the name dates to 1942, so ask how long the present ownership has run it.

What we would want clarified. At 29 miles from central Los Angeles it is the farthest of the five, so Los Angeles County homeowners should confirm coverage. Where solar is part of the pitch, ask for the roofing price separately. We publish this because a ranking that only prints the flattering findings is an advertisement, not an assessment.

Best fit for: Pasadena, Altadena and San Gabriel Valley homeowners, including Eaton fire rebuilds.
What we would want clarified. Founded in 2020, so its long-term warranty record is short. Confirm licence 1077296 is active on the CSLB site. We publish this because a ranking that only prints the flattering findings is an advertisement, not an assessment.

The 45 wind reports that shape a Los Angeles roof
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 2 counties of the Los Angeles-Long Beach-Anaheim, CA statistical area over ten years, with the dates, the stone sizes and the towns they landed on. Over that decade the metro logged 8 hail reports, 45 severe thunderstorm and high wind reports and 6 tornadoes. 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 Los Angeles in a decade
| Date | Stone size | Reported near | County |
|---|---|---|---|
| 3 August 2017 | 1.0 in | Acton | Los Angeles |
| 7 March 2024 | 1.0 in | Granada Hills | Los Angeles |
| 15 March 2024 | 1.0 in | Whittier Jct | Los Angeles |
| 15 March 2024 | 1.0 in | Pico | Los Angeles |
| 24 March 2024 | 1.0 in | Azusa | Los Angeles |
| 24 March 2024 | 0.88 in | El Sereno | Los Angeles |
The largest stone on record for this metro fell on 3 August 2017 near Acton, 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 68 knots, about 78 mph, near Los Angeles on 31 January 2016. Asphalt shingles begin lifting at roughly 67 mph when they are correctly nailed, and considerably below that when they are not.
Tornadoes. 6 tornadoes touched down in these counties over the decade, the strongest rated EF1 near East Los Angeles on 22 March 2023.
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 31 January 2016 event near Dell Vly, reproduced verbatim:
Severe thunderstorms generated strong thunderstorm winds across parts of Los Angeles county. Porter Ranch reported a thunderstorm wind gust of 69 MPH while the RAWS sensors at Chilao and Cheeseboro reported thunderstorm wind gusts between 60 and 63 MPH.
That is the kind of damage a roof in this metro has to be specified against, described by the agency that recorded it rather than by a contractor selling the repair.
When it happens. Severe weather reports cluster in March (19), February (16), October (9). The worst years on record were 2024 (18), 2025 (14), 2016 (9). If you are scheduling non-urgent work in Los Angeles, 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 Los Angeles. Weight your decision toward wind rating, ventilation and flashing detail rather than paying extra for impact-rated shingles.
How to tell a Los Angeles roofer’s claims from their record
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.
How deep the Los Angeles certified market really is
20 certified roofing contractors serve the principal cities of the Los Angeles-Long Beach-Anaheim, CA statistical area, of which 4 hold the top President’s Club tier. The pool carries 2,583 customer reviews between them at a mean rating of 4.675. The statistical area had a 2024 population of 12,927,614, a change of -2.1% against the 2020 census base, per the U.S. Census Bureau Vintage 2024 estimates.
How these Los Angeles rankings were produced
Every contractor in the Los Angeles-Long Beach-Anaheim, 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 20 certified contractors, of whom 4 hold President’s Club standing and 15 Master Elite, against a metro mean rating of 4.675. The top five were then researched individually against Better Business Bureau records, state licence registers and manufacturer directories. Good and bad findings are published together, and no contractor paid for a place here.
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 Los Angeles homeowners want to know
Who is the best roofer in Los Angeles, CA?
NEMA Roofing Solutions of Tarzana, CA scores highest in the Los Angeles metro on The Roofing Brief Contractor Score, at 95.0 out of 100 as of September 2026. It holds President’s Club certification with a 5.0 rating across 299 reviews. Highest-scoring is not the same as best fit for your specific job, and the four companies behind it score within 18.9 points.
How many certified roofing contractors serve Los Angeles?
20 contractors on the GAF certification registry serve the principal cities of the Los Angeles-Long Beach-Anaheim, CA statistical area as of September 2026, of which 4 hold President’s Club status.
How much damaging hail does Los Angeles get?
The Los Angeles-Long Beach-Anaheim, CA statistical area recorded 5 hail reports of 1 inch or larger and 0 of 2 inches or larger between 2016 and 2025 in the NOAA Storm Events Database. The largest hailstone reported measured 1.0 inches.
Did any contractor pay to appear on this list?
No. The Roofing Brief takes no placement fees, no lead fees and no affiliate commission from any roofing contractor. Ranking comes entirely from the published formula applied to public registry data, followed by an individual research pass on the top five.
What was the worst hailstorm in Los Angeles in the last ten years?
The largest hailstone logged by the National Weather Service in the Los Angeles-Long Beach-Anaheim, CA statistical area between 2016 and 2025 measured 1.0 inches, reported near Acton on 3 August 2017. One inch is the point at which hail starts bruising asphalt shingles, which is damage an adjuster can find even when a homeowner cannot. Across the decade the metro recorded 8 hail reports. 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.
When is the worst time of year for roof damage in Los Angeles?
Severe-weather reports in the Los Angeles-Long Beach-Anaheim, CA statistical area cluster in March, February, October, on the NOAA record for 2016 to 2025. Scheduling discretionary work away from that window tends to get you a better crew and a faster start, because nobody is juggling emergency 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.
What should I check before hiring a roofer in Los Angeles?
The CSLB record also shows complaint and disciplinary history, including citations and accusations. Treat any status other than Active as disqualifying.
Is Los Angeles a hard market to find a good roofer in?
The Los Angeles metro’s roof risk is not in its storm record. Ten years of NOAA data for Los Angeles and Orange counties hold eight hail reports, none larger than an inch, 45 severe wind reports and $87,500 in reported damage. The defining event was fire: the Palisades and Eaton fires of January 2025 destroyed more than 16,000 structures, and in the Very High Fire Hazard Severity Zones that cover the hillsides and foothills a replacement roof must be Class A. The ranking has a clear leader. NEMA Roofing Solutions of Tarzana scores 95.0 on a perfect 5.0 across 299 reviews, 12.3 points clear of Chandler’s Roofing, a Gardena business whose roots go back to 1942. California’s C-39 licence, and the CSLB record behind every licence number, does the rest of the vetting.
Is wind or hail the bigger risk to a roof in Los Angeles?
Wind, by a wide margin. The Los Angeles-Long Beach-Anaheim, CA statistical area logged 45 severe thunderstorm and high wind reports against 5 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.
