Short answer: As of October 2026, the one highest-scoring roofing contractors in the Kahului-Wailuku, HI metro on The Roofing Brief Contractor Score are Advanced Roofing Solutions (41.0). Every one holds a manufacturer certification that can be verified independently, every rating below has been corroborated against at least one source outside the certification registry, and no company paid to appear here.
The Roofing Brief scored 1 certified roofing contractors serving the Kahului metro on a published, reproducible formula, then researched each of the top one individually to confirm its record. On Maui the roof threat is wind-driven fire, not hail: in ten years the county logged no hail at all, but 27 wildfires, and on 8 August 2023 a fire pushed by Hurricane Dora’s winds destroyed more than 2,200 structures in Lahaina. Hawaii licenses roofers strictly, but Maui County exempts house reroofs from building permits, so the licence is the main check. One manufacturer-certified roofer with five or more reviews appears in the directory for Maui, and it is ranked; one more long-established Maui roofer is listed for comparison.
The conditions a Kahului roof has to be specified for
Hawaii requires a contractor’s licence, the C-42 Roofing classification for roofers, for any job over $1,500 in labour and materials under the state consumer agency’s current guidance (the Contractors License Board’s FAQ still says $1,000), and for any job needing a building, electrical or plumbing permit. A licence takes four years of supervisory experience in the trade within the last ten, a business and law exam and a trade exam, a five-year credit report for each principal, an accountant-prepared financial statement, and liability and workers’ compensation cover.
Before you sign, a Hawaii contractor must disclose in writing its licence number and classification, the scope of work and how much will be subcontracted, whether it is bonded and your right to demand bonding, its warranties, lien rights and a cost estimate (HAR 16-77-79). The state’s Contractors Recovery Fund pays up to $12,500 per contract, but only if you hired a licensed contractor. We could not confirm whether Hawaii has any law on insurance deductibles.
Maui County Code 16.25.105.2 exempts the reroofing of one- and two-family homes from building permits where the structure is not affected, so no county inspector reviews a typical house reroof. The county builds to the 2018 International Building Code with local amendments, and its rebuilding after declared disasters runs through a separate disaster recovery permit.
Across 2016 to 2025 Maui County logged no hail, no tornadoes and only five thunderstorm wind reports; the county’s whole $100,000 of recorded wind damage is a January 2025 gust that blew one parked aircraft into another at Kahului. The zone records carry the real risk: 27 wildfires, nine high wind events and three hurricanes, with drought recorded in 85 of the 120 months. Kahului’s median home was built in 1978, and 13.2 percent of the county’s housing is held for seasonal use.
The one certified roofer ranked in Kahului, HI
Scored 2026-10-07. The metro mean rating used as the Bayesian prior for Kahului is 4.1, across a pool of 1 certified contractors.
| Rank | Company | TRB Score | Certification | Rating (reviews) | Adjusted | In business since | Based in |

| 1 | Advanced Roofing Solutions | 41.0 | Certified | 4.1 (9) | 4.1 | 2008 | Kahului, HI |
1. Advanced Roofing Solutions: TRB Score 41.0
Advanced Roofing Solutions is based in Kahului, HI, in business since 2008, led by Scott G. Hansen, owner; Tanya Hansen, officer, BBB accredited since 8 December 2016, A+ rating, no complaints closed in three years, and holds Certified standing on the GAF certification registry.

Independently corroborated:
- Advanced Roofing Solutions Inc., incorporated 6 August 2008 as a roofing contractor, officers Scott G. Hansen and Tanya Hansen; annual filings processed every year from 2009 to 2025.. Hawaii Business Express (DCCA)
- No complaint records under the company name or Scott Hansen, in current or archived files.. DCCA complaint history search
- Accredited since December 2016 with an A+ rating; business started August 2008; owner Scott G. Hansen; 15 employees; service area all of Maui County; no complaints.. BBB business profile
What they actually do. New roofs and reroofs, roof coatings and restoration, leak inspection and repair, and roof maintenance.
Why it ranks here. The only GAF-certified roofer on Maui with five or more reviews, a family firm based at the Central Maui Baseyard in Puunene, beside Kahului, serving all of Maui County. Its 2008 founding is confirmed by the state business register, BBB and its own site, and it has no complaints on the state’s complaint history or at BBB. Its owner, who it says has more than 30 years in roofing, publishes Hawaii contractor licence C-29775; the state’s licence search blocked our checks, so we could not confirm the number, class or status ourselves.
Best fit for: Central Maui homeowners who want a local roofer with a clean complaint record and coatings and maintenance as well as reroofs.
What we would want clarified. A thin review base of nine at 4.1, and a licence we could not confirm on the state register: check C-29775 on the state’s licence search before you sign, since the Recovery Fund only covers licensed contractors. 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 (808) 270-9256, 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.
Another long-established Maui roofer
One certified firm is ranked here. This one is the only other Maui roofer we could verify by independent records. It is not scored and we are not recommending it; confirm its C-42 licence on the state search, which blocked our checks.
| Company | Verified credential |

| Top’s Roofing Company, Ltd. | A Wailuku roofing and siding contractor registered as a Hawaii corporation since 1972; BBB accredited since 2017 at A+, with no complaints at BBB or on the state’s complaint history. |
5 severe weather reports in a decade, and why that matters in Kahului
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 Kahului-Wailuku, HI statistical area over ten years, with the dates, the stone sizes and the towns they landed on. Over that decade the metro logged 0 hail reports, 5 severe thunderstorm and high wind reports and 0 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.
Wind. The strongest thunderstorm gust logged in the metro was 56 knots, about 64 mph, near Nahiku on 10 January 2025. 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 10 January 2025 event near Kanaha Bp, reproduced verbatim:
A parked plane was blown into another parked plane. The nose of one plane pierced the bottom of a plane parked perpendicular to it. Damage cost was estimated.
A roof in this metro is built against events like that one, as recorded by the agency that recorded it rather than by a contractor selling the repair.
When it happens. Severe weather reports cluster in January (4), October (1). The worst years on record were 2025 (4), 2017 (1). If you are scheduling non-urgent work in Kahului, 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 Kahului. Weight your decision toward wind rating, ventilation and flashing detail rather than paying extra for impact-rated shingles.
Wind-driven fire, not hail
From 7 to 9 August 2023, strong high pressure north of Hawaii and Hurricane Dora far to the south drove strong northeast winds across Maui. NWS cites very strong trade winds, low humidity and ongoing drought on the leeward side as the reasons the fires that followed grew so fast. Upcountry, trees were uprooted; in West Maui, downed utility poles closed Honoapiilani Highway.
A fire reported near Lahaina at 6:40 on the morning of 8 August was contained within three hours. Another, reported around 3:30 that afternoon, spread out of control after downed power lines closed roads. It burned 2,170 acres and destroyed more than 2,200 structures, most of the historic town. NOAA records 102 deaths, at least 32 injuries, about 4,000 cars destroyed and $5.50 billion of property damage. The same day a brush fire in Kula burned about 200 acres and reportedly destroyed 19 homes.
It was not the first warning. On 26 December 2020 a wind-whipped fire near Olowalu burned more than 750 acres and destroyed the Olowalu Community Center. Over the decade NOAA logged 27 wildfire events in Maui County’s forecast zones, against a county hail count of zero.
Maui’s rebuilding runs through a separate disaster recovery building permit, with pre-approved designs and a factory-built housing route for the Lahaina burn zone. Outside it, ordinary reroofs need no permit at all, so the county inspector who would check a roof in most mainland metros never sees one here. We found no Maui County or state requirement for a Class A fire-rated roof on rebuilds, though we could not read the state’s legislation.
For a Maui homeowner that puts the weight on two checks. First, confirm the roofer’s C-42 licence on the state’s licence search, because without a licence the Recovery Fund will not cover you and no inspector will look at the work. Second, in a county where wind drives fire, ask about the roof’s fire rating and how embers are kept out at the eaves, vents and ridge, even though no code makes you do it.

The checks worth making in Kahului
Licensing is required in HI. Hawaii requires a specialty contractor licence carrying the C-42 Roofing classification for work over $1,500 in labour and materials under the Department of Commerce and Consumer Affairs’ current consumer guidance (the Contractors License Board’s FAQ still gives $1,000), and for any job that needs a building, electrical or plumbing permit, whatever its value.
A C-42 requires at least four years of supervisory experience in the classification, as a foreman, supervising employee or contractor, within the previous ten years (HAR 16-77-18), and passing a Business and Law exam and a trade exam. Applicants file a five-year credit report for each principal and a current financial statement prepared by a certified or registered public accountant, and carry liability insurance of at least $100,000 per person and $300,000 per occurrence for bodily injury and $50,000 for property damage, plus workers’ compensation where they have employees. The Board may also require a bond. The state’s Contractors Recovery Fund pays up to $12,500 per contract and $25,000 per contractor, but only to customers of licensed contractors.
Check here: Hawaii DCCA professional licence search. A Hawaii contractor’s licence means the Board has seen a five-year credit report, an accountant-prepared financial statement, proof of insurance and two passed exams. Check complaint history separately on the DCCA’s Regulated Industries Complaints Office search, and remember that the Recovery Fund only covers you if your contractor was licensed.
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 these Kahului rankings were produced
Every contractor in the Kahului-Wailuku, HI 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 1 certified contractor, of whom 0 hold President’s Club standing and 0 Master Elite, against a metro mean rating of 4.1. The top one were then researched individually against Better Business Bureau records, state licence registers and manufacturer directories. Where that research turned up something awkward it is on the page, and no placement was paid for.
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.

Do roofers need a licence in HI?
Hawaii requires a specialty contractor licence carrying the C-42 Roofing classification for work over $1,500 in labour and materials under the Department of Commerce and Consumer Affairs’ current consumer guidance (the Contractors License Board’s FAQ still gives $1,000), and for any job that needs a building, electrical or plumbing permit, whatever its value. A C-42 requires at least four years of supervisory experience in the classification, as a foreman, supervising employee or contractor, within the previous ten years (HAR 16-77-18), and passing a Business and Law exam and a trade exam. Applicants file a five-year credit report for each principal and a current financial statement prepared by a certified or registered public accountant, and carry liability insurance of at least $100,000 per person and $300,000 per occurrence for bodily injury and $50,000 for property damage, plus workers’ compensation where they have employees.

What should I check before hiring a roofer in Kahului?
A Hawaii contractor’s licence means the Board has seen a five-year credit report, an accountant-prepared financial statement, proof of insurance and two passed exams.

Wind-driven fire, not hail?
From 7 to 9 August 2023, strong high pressure north of Hawaii and Hurricane Dora far to the south drove strong northeast winds across Maui. NWS cites very strong trade winds, low humidity and ongoing drought on the leeward side as the reasons the fires that followed grew so fast. Upcountry, trees were uprooted; in West Maui, downed utility poles closed Honoapiilani Highway.
Is Kahului a hard market to find a good roofer in?
On Maui the roof threat is wind-driven fire, not hail: in ten years the county logged no hail at all, but 27 wildfires, and on 8 August 2023 a fire pushed by Hurricane Dora’s winds destroyed more than 2,200 structures in Lahaina. Hawaii licenses roofers strictly, but Maui County exempts house reroofs from building permits, so the licence is the main check. One manufacturer-certified roofer with five or more reviews appears in the directory for Maui, and it is ranked; one more long-established Maui roofer is listed for comparison.
Is wind or hail the bigger risk to a roof in Kahului?
Wind, by a wide margin. The Kahului-Wailuku, HI statistical area logged 5 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.
