Best Roofers in Riverside, CA: 5 Certified Contractors, Scored and Verified

Short answer: As of September 2026, the five highest-scoring roofing contractors in the Riverside-San Bernardino-Ontario, CA metro on The Roofing Brief Contractor Score are Top Roofing Services (83.5), Guardian Roofs (81.2), TMC Roofing (78.4), Better Roofing (72.6), American Supreme Roofing (72.4). 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 14 certified roofing contractors serving the Riverside metro on a published, reproducible formula, then researched each of the top five individually to confirm its record. The Inland Empire is a heat and ultraviolet market, not a storm market, with only ten damaging-hail reports in the past decade. Roofs here fail from thermal cycling and UV degradation, so material selection and radiant barrier matter more than impact rating, and cool-roof compliance under California’s Title 24 energy code applies to most replacements in this climate zone. One thing to note about this ranking: the two highest-scoring certified contractors serving Riverside are based in Orange County and also serve the Los Angeles metro. They score highest because they are certified, well rated and within range, but if you would rather use a firm headquartered in the Inland Empire itself, the three companies below them are all locally based and we have marked them as such.

What a Riverside roof is up against

The Inland Empire is one of the places where California’s energy code actually changes what you can buy. Riverside sits in Climate Zone 10, and the Coachella Valley end of the metro sits in Zone 14, both inside the range where a steep-slope residential re-roof must use a cool roof product, typically an aged solar reflectance of at least 0.20 with thermal emittance of 0.75, once you replace more than half the roof. That is a product specification, not a formality: ask the contractor to name the CRRC-listed product and show its rating before the permit is filed.

The second layer is fire. Large parts of Riverside and San Bernardino counties are mapped in Fire Hazard Severity Zones, where a Class A fire-rated roof assembly is required. Both counties and the City of Riverside publish the zone maps, and the designation is parcel by parcel rather than neighbourhood by neighbourhood. Check yours before accepting a quote, because a Class A assembly can change the underlayment, the edge detail and the price, and because the rating applies to the whole assembly rather than to the visible covering alone.

The weather here is monsoon-driven and mostly desert. August is the peak month, and the ten-year record holds 115 severe wind reports against 23 hail reports, with the largest stones falling out in the Mojave at Barstow and Mountain Pass rather than in the valley cities. Reported property damage of $10.2 million over the decade is modest for a metro of 4.7 million people. Heat, ultraviolet exposure and thermal cycling do more damage to a roof here than any storm, so underlayment quality and ventilation matter more than impact ratings.

This metro is enormous, stretching from Corona to the Arizona line, and this page ranks only contractors within 40 miles of the Riverside city centre. If you live in Palm Springs, Hemet, Victorville or Temecula, the firms below may be an hour or more away, and a local C-39 licence holder without manufacturer certification can be the better practical choice. Whoever you use, check the licence on the CSLB site, which publishes bond, workers’ compensation and disciplinary history, and remember the down payment cap: $1,000 or 10 per cent of the contract, whichever is less.

1. Top Roofing Services: best overall (TRB Score 83.5)

Top Roofing Services is based in Anaheim, CA, and holds President’s Club standing on the GAF certification registry.

• BuildZoom score 111, in the top 4% of 336,931 licensed California contractors. BuildZoom
• 4.9 across 51 Google reviews and 4.5 on Yelp across 92 reviews. Reviews

What they actually do. Shingle, tile and flat roof installation and leak repair, with a warranty on all work.

Services we could verify: roof repair, flat and low-slope roofing.

Why it ranks here. A BuildZoom score of 111 puts it in the top 4% of every licensed contractor in California, computed from licence and permit history rather than reviews.

Best fit for: Western Inland Empire properties near the Orange County line.

What we would want clarified. Based in Anaheim, in Orange County, rather than in the Inland Empire, and it also ranks in our Los Angeles metro list. The review corpus is also the thinnest here at roughly 143 across platforms. 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 (866) 828-1886, 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. Guardian Roofs: best for older homes (TRB Score 81.2)

Trades as Guardian Roofs; listed on the GAF registry as Guardian Roofs Energy Solutions.

Guardian Roofs is based in Orange, CA, led by Steve Sudduth, BBB accredited, A+ rating, and holds President’s Club standing on the GAF certification registry.

Certifications held: President’s Club (GAF), Owens Corning Platinum Preferred. Certification by more than one manufacturer is uncommon and requires meeting each programme’s separate standards for insurance, training and track record.

• Trading as Sudduth Construction Inc, founded by Steve Sudduth in the early 1980s, explicitly serving Riverside County alongside Orange, Los Angeles and San Diego. Company

What they actually do. Residential and commercial roofing plus energy and solar work across four Southern California counties.

Services we could verify: roof replacement, commercial roofing.

Why it ranks here. Dual-certified by GAF and Owens Corning and holding both General Building and Roofing classifications, which permits structural repair uncovered during a tear-off. Riverside County is a named service area rather than an incidental one.

Best fit for: Older Inland Empire homes where a re-roof may expose framing damage.

What we would want clarified. Headquartered in Orange rather than the Inland Empire, and also ranked in our Los Angeles list. We publish this because a ranking that only prints the flattering findings is an advertisement, not an assessment.

What they actually do. Roof inspection, leak repair, storm damage restoration, re-roofs and 24/7 emergency roofing. Family owned and headquartered in Perris.

Services we could verify: roof replacement, roof repair, storm damage work.

Why it ranks here. The highest-scoring contractor actually headquartered in the Inland Empire, and the only one in this top five offering 24/7 emergency response. Annual crew recertification through GAF’s curriculum is a training commitment beyond the minimum required to hold the tier.

Best fit for: Inland Empire homeowners wanting a genuinely local firm, and emergency leak response.

What we would want clarified. Founded 2022, so the trading record is short, and no BBB profile was locatable. The CSLB licence is current and verifiable. We publish this because a ranking that only prints the flattering findings is an advertisement, not an assessment.

Best fit for: San Bernardino and Colton area homeowners wanting a long-established local firm.

What we would want clarified. No BBB rating and no published CSLB licence number were locatable from the sources we could reach.

Roof replacement and repair in Riverside, CA

Short answer: For a Riverside roof, Top Roofing Services ranks first overall, Guardian Roofs suits older homes where a tear-off may expose framing damage, and TMC Roofing of Perris is the locally headquartered pick for emergency leak repair. Better Roofing and American Supreme Roofing complete the list. The rule that matters most: a stand-alone reroof needs a C-39 roofing licence or a licensed roofing subcontractor (B&P 7057), so verify it at cslb.ca.gov before signing.

The Inland Empire is a heat and ultraviolet market rather than a storm market. The ten-year record holds 115 severe wind reports against 23 hail reports, with only ten damaging-hail reports, and the largest stones fell out in the Mojave at Barstow and Mountain Pass rather than in the valley cities. August is the peak month for severe weather. Reported property damage of $10.2 million over the decade is modest for a metro of 4.7 million people. Roofs here mostly fail from thermal cycling and UV degradation, so when a roof is replaced, material selection, underlayment quality, ventilation and radiant barrier matter more than impact rating.

Code rules shape any replacement. Riverside sits in Climate Zone 10, where a steep-slope residential re-roof replacing more than half the roof must use a cool roof product, typically an aged solar reflectance of at least 0.20 with thermal emittance of 0.75; ask the contractor to name the CRRC-listed product before the permit is filed. Under the 2025 California Residential Code, replacing more than 50 percent of the roof area within one year outside fire hazard severity zones requires the whole covering to be at least Class C, and inside those zones the Wildland-Urban Interface Code requires Class A. Any replacement roof must be torn off to the deck (CRC R908.3).

Fire zone designation is parcel by parcel, and both counties and the City of Riverside publish the maps, so check yours before accepting a quote, since a Class A assembly can change the underlayment, edge detail and price. Many cities adopt stricter local amendments, so confirm with your city or county building department. On contracts, California caps the down payment at $1,000 or 10 per cent of the contract, whichever is less. For replacement cost policies, Cal. Code Regs. tit. 10, section 2695.9(a)(2) requires the insurer to replace all items in the damaged area to a reasonably uniform appearance when replaced items do not match in quality, color or size.

For repair, TMC Roofing in Perris lists inspection, leak repair, storm damage restoration, re-roofs and 24/7 emergency roofing, and is the only firm in this top five offering 24/7 response. Top Roofing Services covers shingle, tile and flat roof installation and leak repair. Guardian Roofs holds both General Building and Roofing classifications, which permits structural repair uncovered during a tear-off, and also does commercial work. Better Roofing in Grand Terrace has over 35 years of experience, though you should ask for its licence number. American Supreme Roofing suits homeowners comparing Orange County and Inland Empire quotes. Owners in Palm Springs, Hemet, Victorville or Temecula may find a local C-39 licence holder more practical.

Replacing a roof in Riverside: the rules that apply

The 115 wind reports that shape a Riverside 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 Riverside-San Bernardino-Ontario, CA statistical area over ten years, with the dates, the stone sizes and the towns they landed on. Over that decade the metro logged 23 hail reports, 115 severe thunderstorm and high wind reports and 5 tornadoes. Reported property damage from hail, severe wind and tornado over that decade totalled $10.2 million; flood and winter-storm losses are counted separately and are not included.

The biggest hail to fall on Riverside in a decade

Date	Stone size	Reported near	County
1 July 2016	1.75 in	Barstow	San Bernardino
22 August 2020	1.75 in	Mountain Pass	San Bernardino
3 June 2025	1.0 in	Joshua Tree	San Bernardino
3 June 2025	1.0 in	Chambless	San Bernardino
8 September 2024	1.0 in	Ethanac	Riverside
12 October 2018	1.0 in	Indio	Riverside

The largest stone on record for this metro fell on 1 July 2016 near Barstow, measured at 1.75 inches. That is ping-pong-ball sized, enough to bruise asphalt shingles and shorten a roof’s life without necessarily looking dramatic from the ground.

Wind. The strongest thunderstorm gust logged in the metro was 75 knots, about 86 mph, near San Bernardino on 26 August 2016. Asphalt shingles begin lifting at roughly 67 mph when they are correctly nailed, and considerably below that when they are not.

Tornadoes. 5 tornadoes touched down in these counties over the decade, the strongest rated EF0 near Adelanto on 7 May 2017.

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 26 August 2016 event near San Bernardino, reproduced verbatim:

There was substantial damage at the airport, including at least two airplanes. A nearby residence also had property and tree damage.

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 August (57), July (31), September (31). The worst years on record were 2022 (29), 2024 (27), 2021 (20). If you are scheduling non-urgent work in Riverside, 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 Riverside. Weight your decision toward wind rating, ventilation and flashing detail rather than paying extra for impact-rated shingles.

What a Riverside homeowner should ask for in writing

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: under Business and Professions Code 7048 it applies only to minor work under $1,000 that needs no building permit, and is lost if the person employs anyone or advertises as a contractor. Roofing is the C-39 classification. A B General Building contractor may include roofing in a multi-trade project, but a stand-alone reroof needs a C-39 licence or a licensed roofing subcontractor (B&P 7057).

A C-39 qualifier must document at least four years of journey-level experience and normally passes both a trade examination and a law and business examination unless a statutory waiver applies. 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.

For what a full replacement costs across California, including state labor rates and permit rules, see our California roof replacement cost guide.

Four checks to run before you sign anything, in any state.

1. Verify certification at the source. Use the GAF verification tool rather than trusting a badge image on a company website.
2. 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.
3. Confirm who pulls the permit. If a contractor asks you to pull it as the homeowner, that moves liability onto you. Decline.
4. Get warranty terms in writing before any deposit, and check the manufacturer warranty being promised actually requires the certification tier the contractor holds.

How many certified roofers Riverside actually has

14 certified roofing contractors serve the principal cities of the Riverside-San Bernardino-Ontario, CA statistical area, of which 2 hold the top President’s Club tier. The pool carries 1,159 customer reviews between them at a mean rating of 4.771. The statistical area had a 2024 population of 4,744,214, a change of 3.1% against the 2020 census base, per the U.S. Census Bureau Vintage 2024 estimates.

How these Riverside rankings were produced

Every contractor in the Riverside-San Bernardino-Ontario, 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 14 certified contractors, of whom 2 hold President’s Club standing and 11 Master Elite, against a metro mean rating of 4.771. 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. Last updated: September 2026. Scoring run: 2026-09-12. Corrections go to the editor and are actioned on verification.

Common questions about roofers in Riverside

Who is the best roofer in Riverside, CA?

Top Roofing Services of Anaheim, CA scores highest in the Riverside metro on The Roofing Brief Contractor Score, at 83.5 out of 100 as of September 2026. It holds President’s Club certification with a 4.9 rating across 56 reviews. Highest-scoring is not the same as best fit for your specific job, and the four companies behind it score within 11.1 points.

What is the 25% rule for roofing in California?

California has no 25 percent rule; its statewide trigger is 50 percent. If more than 50 percent of the roof area is replaced within one year outside fire hazard severity zones, the whole covering must be at least Class C, and inside Fire Hazard Severity Zones or Wildland-Urban Interface areas it must meet new-construction Class A standards. Many cities adopt stricter local amendments, so check with your city or county building department.

Who does roof repair in Riverside?

TMC Roofing, headquartered in Perris, offers leak repair, storm damage restoration and 24/7 emergency roofing, and holds C-39 licence 1103611. Top Roofing Services lists leak repair across shingle, tile and flat roofs. Guardian Roofs holds General Building and Roofing classifications, which permits structural repair uncovered during a tear-off.

Does a new roof in Riverside have to be a cool roof?

Usually, yes. Riverside sits in Climate Zone 10, where a steep-slope residential re-roof replacing more than half the roof must use a cool roof product, typically an aged solar reflectance of at least 0.20 with thermal emittance of 0.75. Ask the contractor to name the CRRC-listed product and show its rating before the permit is filed.

Does hail damage roofs much in Riverside, California?

Not often. The ten-year record holds 23 hail reports against 115 severe wind reports, with the largest stones falling at Barstow and Mountain Pass rather than in the valley cities. Heat, ultraviolet exposure and thermal cycling do more damage to roofs here than any storm.

How many certified roofing contractors serve Riverside?

14 contractors on the GAF certification registry serve the principal cities of the Riverside-San Bernardino-Ontario, CA statistical area as of September 2026, of which 2 hold President’s Club status.

How much damaging hail does Riverside get?

The Riverside-San Bernardino-Ontario, CA statistical area recorded 10 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 1.75 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 Riverside in the last ten years?

The largest hailstone logged by the National Weather Service in the Riverside-San Bernardino-Ontario, CA statistical area between 2016 and 2025 measured 1.75 inches, reported near Barstow on 1 July 2016. That is ping-pong-ball sized, enough to bruise asphalt shingles and shorten a roof’s life without necessarily looking dramatic from the ground. Across the decade the metro recorded 23 hail reports. Reported property damage from hail, severe wind and tornado over that decade totalled $10.2 million; flood and winter-storm losses are counted separately and are not included.

When is the worst time of year for roof damage in Riverside?

Severe-weather reports in the Riverside-San Bernardino-Ontario, CA statistical area cluster in August, July, September, 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: under Business and Professions Code 7048 it applies only to minor work under $1,000 that needs no building permit, and is lost if the person employs anyone or advertises as a contractor. Roofing is the C-39 classification. A B General Building contractor may include roofing in a multi-trade project, but a stand-alone reroof needs a C-39 licence or a licensed roofing subcontractor (B&P 7057). A C-39 qualifier must document at least four years of journey-level experience and normally passes both a trade examination and a law and business examination unless a statutory waiver applies. 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 Riverside?

The CSLB record also shows complaint and disciplinary history, including citations and accusations. Treat any status other than Active as disqualifying.

Is Riverside a hard market to find a good roofer in?

The Inland Empire is a heat and ultraviolet market, not a storm market, with only ten damaging-hail reports in the past decade. Roofs here fail from thermal cycling and UV degradation, so material selection and radiant barrier matter more than impact rating, and cool-roof compliance under California’s Title 24 energy code applies to most replacements in this climate zone. One thing to note about this ranking: the two highest-scoring certified contractors serving Riverside are based in Orange County and also serve the Los Angeles metro. They score highest because they are certified, well rated and within range, but if you would rather use a firm headquartered in the Inland Empire itself, the three companies below them are all locally based and we have marked them as such.

Is wind or hail the bigger risk to a roof in Riverside?

Wind, by a wide margin. The Riverside-San Bernardino-Ontario, CA statistical area logged 115 severe thunderstorm and high wind reports against 10 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.
