Short answer: As of September 2026, the five highest-scoring roofing contractors in the Fresno, CA metro on The Roofing Brief Contractor Score are Grandmark Roofing, trading as Grandmark Service Company, Inc. (80.7), Borgen’s Construction, Inc. (79.1), Universal Coatings Inc. (67.4), High Impact Roofing, Inc. (67.2), Vezina Industries Inc (63.0). 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 8 certified roofing contractors serving the Fresno metro on a published, reproducible formula, then researched each of the top five individually to confirm its record. Fresno has the weakest certified roofing market of any metro published so far. The metro mean rating of 4.69 is the lowest across all fifty, the leading score of 79.6 is among the lowest, and three of the five below sit at base certification rather than a higher tier. That is a real characteristic of this market, not a scoring quirk, and it is why California’s licensing regime carries more weight here than certification tier does. Any roofing job over $500 requires a Contractors State License Board licence under C-39, and every company below has a verifiable number.
Wind, terrain and the Fresno housing stock
Fresno sits in California Climate Zone 13, one of the hottest in the state, and the energy code bites on both roof types here. For a re-roof replacing more than half the covering, steep-slope roofs must meet an aged solar reflectance of 0.20 with 0.75 emittance or an equivalent solar reflectance index, and low-slope roofs face a considerably higher reflectance standard. The code allows alternative compliance paths on steep slopes, including R-38 ceiling insulation, an attic radiant barrier or keeping ducts out of the attic. Ask which path the contractor is using before the permit is filed.
The City of Fresno requires a permit for a roof replacement inside city limits, and the energy compliance paperwork goes with it. That paperwork is worth keeping: it records the product installed and the compliance route chosen, which is exactly what a future buyer’s inspector or an insurer will ask about. Unincorporated addresses in Fresno and Madera counties permit through the county instead, so confirm which authority covers your house.
There is almost no storm risk to a roof here. The metro recorded five hail reports in ten years, 36 severe wind reports and eight mostly weak tornadoes, with $911,000 in reported property damage. What destroys roofs in the San Joaquin Valley is heat: summer air temperatures above 110 degrees, roof surfaces far hotter, and daily thermal cycling that ages asphalt faster than the warranty period assumes. Attic ventilation and a reflective covering are the two things that measurably slow it.
That heat also shapes what to ask for. Ask what intake and exhaust ventilation the roof will have, whether the attic has ducts running through it, and what underlayment is specified, because cheap felt fails quickly under a Valley roof deck. California licenses roofing as Class C-39, and the CSLB record shows bond, workers’ compensation and disciplinary history; use it, and remember the down payment on a home improvement contract is capped at $1,000 or 10 per cent of the price, whichever is less.

1. Grandmark Roofing, trading as Grandmark Service Company, Inc. — TRB Score 80.7
Trades as Grandmark Roofing, trading as Grandmark Service Company, Inc.; listed on the GAF registry as Grandmark Roofing.
Grandmark Roofing, trading as Grandmark Service Company, Inc. is based in Fresno, CA, led by Miguel and Carlos Colima, BBB a+ rating, not BBB accredited, and holds Master Elite standing on the GAF certification registry.
| Score component | Points | Max |

- A+ rated, though not BBB accredited. BBB
- Licence 1030917 covering Roofing, General Building, and Warm Air Heating, Ventilating and Air Conditioning, verified active. CSLB
- 4.7 averaged across Google, Yelp and BBB. Reviews
What they actually do. Residential and commercial roofing including flat roof repair and emergency roofing, plus HVAC.
Why it ranks here. Nearly 30 years in this market under Miguel and Carlos Colima, with 714 registry reviews, by far the deepest evidence base in the Fresno pool. Holding a General Building classification alongside roofing permits structural repair uncovered mid-project.
Best fit for: Homeowners wanting the deepest local record, and jobs that may expose structural damage.
What we would want clarified. A+ rated but not BBB accredited, so no BBB complaint-resolution commitment exists. 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 (559) 272-7495, 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. Borgen’s Construction, Inc. — TRB Score 79.1

Independently corroborated:
- Not BBB accredited, trading since 5 April 2021, president Orlando Borgen. BBB
- CSLB licence 1074527. CSLB
What they actually do. Roofing, HVAC, windows and energy-efficient home improvements, family owned.
Why it ranks here. A 4.9 across 143 registry reviews, the strongest rating in the Fresno pool, from a family-owned firm combining roofing with HVAC and energy work. In a metro where summer heat governs, addressing roof and attic cooling together is the sensible pairing.
Best fit for: Homeowners tackling roof and cooling performance in one project.
What we would want clarified. Not BBB accredited, trading only since 2021, and independent review volume outside the registry is very thin. Verify CSLB licence 1074527 directly 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 (559) 399-5014, 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. Universal Coatings Inc. — TRB Score 67.4
Universal Coatings Inc. is based in Fresno, CA, in business since 1978, BBB a+ rating, not accredited, zero complaints, 24 years on the BBB record, and holds Master Elite standing on the GAF certification registry.

- Founded in Fresno in 1978, specialising in polyurethane foam roofing, roof coating systems, single ply roofing and industrial coatings. Company
What they actually do. Polyurethane foam roofing, roof coating systems and renewals, single ply roofing, tank and cold storage insulation and industrial coatings.
Why it ranks here. Founded 1978, the longest record in the Fresno pool, and the only contractor here holding an asbestos abatement classification, which matters on older commercial and agricultural buildings across the Central Valley. Foam and coating systems are a genuinely different specialism from shingle roofing.
Best fit for: Flat, foam and coated roofs, commercial and agricultural buildings, and older structures where asbestos may be present.
What we would want clarified. At 19 registry reviews this is the thinnest evidence base of any contractor ranked in this batch, and the company carries zero BBB reviews. It is primarily a commercial and industrial coatings specialist rather than a residential shingle roofer. We publish this because a ranking that only prints the flattering findings is an advertisement, not an assessment.

What they actually do. Residential and commercial roofing, repairs and gutter services.
Why it ranks here. A clean 5.0 across 79 registry reviews and 5.0 on both Angi and HomeAdvisor simultaneously, with a published and bonded CSLB licence.
Best fit for: Fresno homeowners wanting a clean cross-platform record with verifiable licensing.
What we would want clarified. Base GAF certification rather than a higher tier, and at 79 registry reviews the evidence base is modest. Trading only since 2019. We publish this because a ranking that only prints the flattering findings is an advertisement, not an assessment.

- Rated 5.0 on Houzz, Angi and HomeAdvisor, with over 500 five-star reviews. Reviews
What they actually do. Roofing installation alongside attic, batt, blown-in, spray foam and commercial insulation, HVAC and window replacement.
Why it ranks here. Fifteen years of unbroken A+ accreditation with 40 full-time employees. The insulation specialism is the most relevant capability in this metro: in Fresno’s summer heat, attic insulation and ventilation do more for a home than the shingle grade does.
Best fit for: Homeowners treating the roof as a heat problem rather than just a weather problem.
What we would want clarified. Based in Madera rather than Fresno proper, and the CSLB classifications listed centre on general building and insulation rather than a standalone roofing classification. Confirm the roofing scope is covered by the licence held. We publish this because a ranking that only prints the flattering findings is an advertisement, not an assessment.

The 36 wind reports that shape a Fresno 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 Fresno, CA statistical area over ten years, with the dates, the stone sizes and the towns they landed on. Over that decade the metro logged 5 hail reports, 36 severe thunderstorm and high wind reports and 8 tornadoes. Reported property damage from hail, severe wind and tornado over that decade totalled $911,000; flood and winter-storm losses are counted separately and are not included.
The biggest hail to fall on Fresno in a decade
| Date | Stone size | Reported near | County |
|---|---|---|---|
| 5 June 2023 | 1.0 in | Beasore | Madera |
| 11 March 2023 | 1.0 in | Ingle | Fresno |
| 12 March 2023 | 1.0 in | Dairyland | Madera |
| 3 February 2019 | 0.88 in | Raymond | Madera |
| 19 May 2019 | 0.5 in | Westhaven | Fresno |
The largest stone on record for this metro fell on 5 June 2023 near Beasore, 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 Mendota on 11 September 2017. Asphalt shingles begin lifting at roughly 67 mph when they are correctly nailed, and considerably below that when they are not.
Tornadoes. 8 tornadoes touched down in these counties over the decade, the strongest rated EF2 near Central Camp on 5 September 2020.
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 19 May 2019 event near Westhaven, reproduced verbatim:
Three power poles were slightly blown over and a trampolene was blown over east of the intersection of Gale Ave. and Howard Ave.
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 (16), September (9), August (8). The worst years on record were 2023 (24), 2019 (9), 2017 (7). If you are scheduling non-urgent work in Fresno, 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 Fresno. Weight your decision toward wind rating, ventilation and flashing detail rather than paying extra for impact-rated shingles.
Before you sign anything in Fresno
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 Fresno contractor market

How these Fresno rankings were produced
Every contractor in the Fresno, 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 8 certified contractors, of whom 0 hold President’s Club standing and 4 Master Elite, against a metro mean rating of 4.688. 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.

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 Fresno in the last ten years?
The largest hailstone logged by the National Weather Service in the Fresno, CA statistical area between 2016 and 2025 measured 1.0 inches, reported near Beasore on 5 June 2023. 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 5 hail reports. Reported property damage from hail, severe wind and tornado over that decade totalled $911,000; flood and winter-storm losses are counted separately and are not included.
When is the worst time of year for roof damage in Fresno?
Severe-weather reports in the Fresno, CA statistical area cluster in March, September, August, 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.
What should I check before hiring a roofer in Fresno?
The CSLB record also shows complaint and disciplinary history, including citations and accusations. Treat any status other than Active as disqualifying.
Is Fresno a hard market to find a good roofer in?
Fresno has the weakest certified roofing market of any metro published so far. The metro mean rating of 4.69 is the lowest across all fifty, the leading score of 79.6 is among the lowest, and three of the five below sit at base certification rather than a higher tier. That is a real characteristic of this market, not a scoring quirk, and it is why California’s licensing regime carries more weight here than certification tier does. Any roofing job over $500 requires a Contractors State License Board licence under C-39, and every company below has a verifiable number.
Is wind or hail the bigger risk to a roof in Fresno?
Wind, by a wide margin. The Fresno, CA statistical area logged 36 severe thunderstorm and high wind reports against 3 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.
