Short answer: As of October 2026, the four highest-scoring roofing contractors in the Bozeman, MT metro on The Roofing Brief Contractor Score are Langley Roofing (86.7), Ace Roofing (85.4), Meridian Roofing Services (76.7), Lost River Roofing (63.3). 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 4 certified roofing contractors serving the Bozeman metro on a published, reproducible formula, then researched each of the top four individually to confirm its record. Bozeman roofs are designed for snow, not hail: the city requires a 41 psf roof snow load, well above Montana’s 30 psf minimum and Missoula’s, and none of the county’s 26 hail reports in a decade recorded any damage. Every reroof needs a permit, a full tear-off and a dry-in inspection with the ice barrier exposed before shingles go on. Half the city’s homes date from 2000 or later, and only four certified roofers serve the market.
Quick picks for Bozeman:
- Langley Roofing: best overall (TRB Score 86.7). Verified services: roof replacement, roof repair, inspections and maintenance.
- Ace Roofing: best for large or complex roofs (TRB Score 85.4). Verified services: commercial roofing, flat and low-slope roofing, metal roofing, cedar and shake, inspections and maintenance.
- Meridian Roofing Services: longest-established Gallatin Valley firm (TRB Score 76.7). Verified services: roof replacement, roof repair, inspections and maintenance, storm damage work, siding.
- Lost River Roofing: best for the west Gallatin Valley (TRB Score 63.3). Verified services: commercial roofing, roof repair, inspections and maintenance.
The conditions a Bozeman roof has to be specified for
Since 1 January 2026 Montana requires a construction contractor licence from the Department of Labor and Industry for roofing work. There is no exam or roofing-specific licence, and the department polices fraud and worker misclassification but says it does not judge workmanship. Jobs under $2,500 and one-person firms with no employees are exempt, so check the record type on the state register, not just that a number exists.
The City of Bozeman requires a building permit for any reroof of a house or townhouse, with a scope narrative and the manufacturer’s specifications, and the permit must be posted on site. A reroof must strip existing coverings to the deck, apart from an adhered ice barrier membrane, and replacing rafters, trusses or sheathing turns it into an alteration permit with plan review.
Bozeman designs for a 46 psf ground snow load, a 41 psf roof snow load and a 115 mph basic wind speed, with an ice barrier at the eaves required under Montana’s statewide amendment. The 2024 building codes, adopted by Montana on 26 September 2026, apply to Bozeman applications from 1 January 2027. Outside cities that adopt the state code, rural Gallatin County homes of fewer than five units may need no building permit at all.
Montana has no law against a roofer rebating your insurance deductible and no special right to cancel a storm-claim contract; the only cancellation right is three business days after an uninvited door-to-door sale over $25. The state insurance commissioner warns that hail damage on a roof 10 to 15 years old may be paid at actual cash value, and that a 5 percent deductible on a $325,000 home costs $16,250.

What they actually do. Residential roof replacement, repair and maintenance, with insurance claim help.
Services we could verify: roof replacement, roof repair, inspections and maintenance.
Why it ranks here. The top-scoring firm, a Master Elite roofer with 134 GAF reviews averaging 5.0, owner-led and holding Owens Corning Preferred status too. The licensed company is based in Manhattan, about 20 miles west, with a Bozeman address on GAF, and its site covers Bozeman and Big Sky. It is a separate company from Missoula’s Jared Langley; we found no link between them.
Best fit for: Bozeman and Big Sky homeowners who want an owner-run residential specialist with the strongest review record in the valley.
What we would want clarified. We found no BBB profile under any of its names, so there is no complaint history to check. 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 (406) 898-9368, 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.

What they actually do. Large commercial roofing in single-ply membrane and metal, residential shingle, cedar and synthetic shake, and roof maintenance.
Services we could verify: commercial roofing, flat and low-slope roofing, metal roofing, cedar and shake, inspections and maintenance.
Why it ranks here. The largest firm here, with 291 GAF reviews averaging 4.9, and the only one holding both GAF Master Elite and Owens Corning’s top Platinum Preferred tier. It is no longer locally owned: since January 2024 it has belonged to Omnia Exterior Solutions, a private equity backed roofing group, which BBB and the trade press both confirm. Sources disagree on its founding year, so we give none.
Best fit for: Owners of large or complex roofs, including commercial buildings and shake or synthetic roofs, who want the deepest crew and two top manufacturer tiers.
What we would want clarified. Ownership changed in January 2024 to a private equity backed group, commercial work is a large share of its business, and its BBB accreditation dates only from May 2026.

Roof replacement and repair in Bozeman, MT
Short answer: For a Bozeman roof, Langley Roofing is the owner-run residential specialist with the strongest review record, Ace Roofing suits large, commercial or shake roofs, Meridian Roofing Services in Belgrade has nearly 30 years in the valley, and Lost River Roofing serves Three Forks and the west valley. The rule that matters most: every Bozeman house reroof needs a permit, a full tear-off and a dry-in inspection with the ice barrier exposed.
Bozeman roofs are designed for snow, not hail. The city sets a 46 psf ground snow load and a 41 psf roof snow load, above Montana’s 30 psf minimum, and the heavy wet snow of 24 March 2023 brought 25 inches at Montana State University. From 2016 to 2025 Gallatin County logged 26 hail reports, none larger than 1.75 inches and none with recorded property damage. Wind adds to the load: a dry microburst gusted to 79 mph at Belgrade airport on 30 August 2021, and in the 17 December 2025 windstorm a spotter near Amsterdam measured 78 mph.
Every reroof of a house or townhouse in Bozeman needs a building permit, with a scope narrative and the manufacturer’s specifications, posted on site. A reroof must strip existing coverings to the deck, apart from an adhered ice barrier membrane, so overlays are out, and after tear-off work stops for a dry-in inspection with underlayment, ice barrier and flashing exposed. Replacing rafters, trusses or sheathing turns the job into an alteration permit with plan review. The 2024 codes apply to Bozeman applications from 1 January 2027, while rural Gallatin County homes of fewer than five units may need no building permit at all.
Montana has no law against a roofer rebating your insurance deductible and no special right to cancel a storm-claim contract; the only cancellation right is three business days after an uninvited door-to-door sale over $25. There is no matching statute, but Commissioner advisory memoranda state that damaged materials must be replaced with similar quality, kind, texture and color for a reasonable match. The insurance commissioner warns that hail damage on a roof 10 to 15 years old may be paid at actual cash value. Half the city’s homes date from 2000 or later, so many first-generation roofs are reaching replacement age.
For residential replacement and repair, Langley Roofing covers installation, repair and maintenance across Bozeman and Big Sky, and Meridian Roofing Services lists replacement, repair, inspections, storm damage and siding. Ace Roofing handles large commercial roofs in single-ply membrane and metal, plus residential shingle and cedar or synthetic shake; it has belonged to a private equity backed group since January 2024. Lost River Roofing does residential and commercial roofing and repairs and offers a follow-up inspection a year after the job, useful after a first winter under snow load; make sure the contract names its licensed entity, Lost River Properties LLC.

24 inch-plus hail reports and 49 wind reports over Bozeman
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 Bozeman, MT statistical area over ten years, with the dates, the stone sizes and the towns they landed on. Over that decade the metro logged 26 hail reports, 49 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.
The biggest hail to fall on Bozeman in a decade
| Date | Stone size | Reported near | County |
|---|---|---|---|
| 7 July 2020 | 1.75 in | Bozeman | Gallatin |
| 25 May 2023 | 1.75 in | Bozeman Hot Spgs | Gallatin |
| 28 July 2023 | 1.75 in | Sedan | Gallatin |
| 28 July 2023 | 1.75 in | Sedan | Gallatin |
| 11 August 2019 | 1.5 in | Belgrade | Gallatin |
| 25 May 2023 | 1.5 in | Bozeman Hot Spgs | Gallatin |
The largest stone on record for this metro fell on 7 July 2020 near Bozeman, 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 70 knots, about 81 mph, near West Yellowstone on 16 July 2019. 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 16 July 2019 event near West Yellowstone, reproduced verbatim:
The public reported about two dozen large trees downed by thunderstorm winds at the KOA near West Yellowstone. Some tents and awnings were destroyed. Wind speed and time were estimated.
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 July (36), August (19), June (7). The worst years on record were 2020 (15), 2024 (14), 2021 (12). If you are scheduling non-urgent work in Bozeman, 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 Bozeman. Weight your decision toward wind rating, ventilation and flashing detail rather than paying extra for impact-rated shingles.
Built for snow: a 41 psf roof load, a mandatory dry-in inspection, and a housing stock half built since 2000
Bozeman’s building official has set a 46 psf ground snow load and a 41 psf roof snow load, well above the 30 psf minimum roof snow load Montana sets statewide and Missoula uses. The heavy wet snow of 24 March 2023 shows why: nearly two feet fell on the Bozeman fire station in under 12 hours, Montana State University measured 25 inches, and Four Corners and Bozeman Hot Springs had 18 to 24 inches.
Hail is a smaller threat than in eastern Montana. From 2016 to 2025 Gallatin County logged 26 hail reports, none larger than 1.75 inches and none with any recorded property damage, against 39 heavy snow and 73 high wind reports in the county’s forecast zones. July brings most of the summer storms, 36 of the 75 hail and wind reports, and dry microbursts can surprise: on 30 August 2021 a weak shower collapsed into a 79 mph gust at Belgrade airport with no lightning at all.
Winter wind adds to the load. In the 17 December 2025 windstorm Bozeman airport gusted above 58 mph and a spotter near Amsterdam measured 78 mph, with 100-foot pines snapped. That storm is filed under the Gallatin Valley forecast zone, not the county, so county storm counts miss it.
Bozeman’s answer is inspection. Every reroof needs a permit, and after tear-off work must stop for a dry-in inspection with the underlayment, ice barrier and flashing exposed; the city calls it the single most important inspection and can make a contractor strip shingles laid before it. A replacement must go back to the deck rather than overlay, except where an adhered ice barrier can stay.
The houses carrying these loads are young: 49.8 percent of the city’s housing units were built in 2000 or later and 30.2 percent since 2010, against 33.6 and 17.8 percent in Missoula. Many first-generation roofs on those homes are now reaching replacement age, and 55 percent of the city’s homes are rented, so landlords make many of the decisions. Ask any roofer how they schedule the dry-in inspection and whether their price includes a full tear-off.

What a Bozeman homeowner should ask for in writing
Licensing is required in MT. Since 1 January 2026 Montana requires a construction contractor licence from the Department of Labor and Industry for anyone in the business of installing or repairing roofing (MCA 37-45-201). It replaced the old contractor registration, and there is no exam or roofing-specific licence.
The licence requires proof of workers’ compensation compliance. Two exemptions matter: jobs under $2,500 in total, and independent contractors with no employees, whatever the job size, so a one-person roofer may legitimately hold only an Independent Contractor Exemption Certificate. Cities and counties cannot add their own contractor licence or bond, but they can require a general business licence: Missoula, for example, issues a Contractor Business License to construction firms working in the city. Unprofessional conduct carries penalties of up to $5,000.
Check here: Montana DLI construction contractor record search. Licence numbers look like CCP-CCL-LIC-0000000; an exemption certificate starts ICP-ICEC-REG, so check the record type, not just that a number exists. The department polices fraud, misrepresentation and worker classification but does not judge workmanship, so check warranties, references and the contractor’s insurance separately.
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 Bozeman field looks like
4 certified roofing contractors serve the principal cities of the Bozeman, MT statistical area, of which 0 hold the top President’s Club tier. The pool carries 461 customer reviews between them at a mean rating of 4.975. The statistical area had a 2024 population of 126,984, a change of 6.74% against the 2020 census base, per the U.S. Census Bureau Vintage 2024 estimates.
How these Bozeman rankings were produced
Every contractor in the Bozeman, MT 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 4 certified contractors, of whom 0 hold President’s Club standing and 3 Master Elite, against a metro mean rating of 4.975. The top four 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: October 2026. Scoring run: 2026-10-12. Corrections go to the editor and are actioned on verification.
Questions Bozeman homeowners ask

It holds Master Elite certification with a 5.0 rating across 134 reviews.

What is the 25% rule for roofing in Montana?
Montana has no 25 percent roof rule. Where the 2024 IRC applies, a roof replacement must be torn off to the deck and a recover is not allowed over a water-soaked or deteriorated roof, slate or tile, or two existing layers. The state code does not apply to homes with fewer than five units unless the local city, county or town has made it applicable.
Do I need a permit to replace a roof in Bozeman?
Yes. The City of Bozeman requires a building permit for any reroof of a house or townhouse, a full tear-off to the deck, and a dry-in inspection with the underlayment, ice barrier and flashing exposed before shingles go on.
Who does roof repair in Bozeman?
Langley Roofing lists residential roof repair and maintenance in Bozeman and Big Sky, and Meridian Roofing Services in Belgrade lists repair, inspections and storm damage work. Lost River Roofing in Three Forks also does repairs and runs a maintenance programme.
How do I know if a roofer in Bozeman is good?
Check the Montana Department of Labor and Industry register and confirm the record type is a construction contractor licence, not an exemption certificate. The department does not judge workmanship, so check warranties, references and insurance separately, and ask how the roofer schedules the dry-in inspection.
How many certified roofing contractors serve Bozeman?

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 four.
What was the worst hailstorm in Bozeman in the last ten years?
The largest hailstone logged by the National Weather Service in the Bozeman, MT statistical area between 2016 and 2025 measured 1.75 inches, reported near Bozeman on 7 July 2020. 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 26 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 Bozeman?
Severe-weather reports in the Bozeman, MT statistical area cluster in July, August, June, 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 MT?
Since 1 January 2026 Montana requires a construction contractor licence from the Department of Labor and Industry for anyone in the business of installing or repairing roofing (MCA 37-45-201). It replaced the old contractor registration, and there is no exam or roofing-specific licence. The licence requires proof of workers’ compensation compliance. Two exemptions matter: jobs under $2,500 in total, and independent contractors with no employees, whatever the job size, so a one-person roofer may legitimately hold only an Independent Contractor Exemption Certificate. Cities and counties cannot add their own contractor licence or bond, but they can require a general business licence: Missoula, for example, issues a Contractor Business License to construction firms working in the city. Unprofessional conduct carries penalties of up to $5,000.
What should I check before hiring a roofer in Bozeman?
Licence numbers look like CCP-CCL-LIC-0000000; an exemption certificate starts ICP-ICEC-REG, so check the record type, not just that a number exists. The department polices fraud, misrepresentation and worker classification but does not judge workmanship, so check warranties, references and the contractor’s insurance separately.
Built for snow: a 41 psf roof load, a mandatory dry-in inspection, and a housing stock half built since 2000?
Bozeman’s building official has set a 46 psf ground snow load and a 41 psf roof snow load, well above the 30 psf minimum roof snow load Montana sets statewide and Missoula uses. The heavy wet snow of 24 March 2023 shows why: nearly two feet fell on the Bozeman fire station in under 12 hours, Montana State University measured 25 inches, and Four Corners and Bozeman Hot Springs had 18 to 24 inches.
Is Bozeman a hard market to find a good roofer in?
Bozeman roofs are designed for snow, not hail: the city requires a 41 psf roof snow load, well above Montana’s 30 psf minimum and Missoula’s, and none of the county’s 26 hail reports in a decade recorded any damage. Every reroof needs a permit, a full tear-off and a dry-in inspection with the ice barrier exposed before shingles go on. Half the city’s homes date from 2000 or later, and only four certified roofers serve the market.
Is wind or hail the bigger risk to a roof in Bozeman?
Wind, by a wide margin. The Bozeman, MT statistical area logged 49 severe thunderstorm and high wind reports against 24 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.
