Short answer: As of September 2026, the five highest-scoring roofing contractors in the Greeley, CO metro on The Roofing Brief Contractor Score are T Bare Roofing (84.8), Green Top Roofing (76.5), Northern Lights Exteriors (75.1), Trusted Roofing LLC (72.6), All Phase Restoration Inc (71.3). Each holds a certification we verified on the manufacturer’s own register, every rating was corroborated elsewhere, and placement on this page is not for sale.
The Roofing Brief scored 7 certified roofing contractors serving the Greeley metro on a published, reproducible formula, then researched each of the top five individually to confirm its record. Weld County is the most hail-exposed metro in this programme’s recent batches: 431 hail reports over the decade, 374 of them an inch or larger, with a 4.25 inch stone near Pierce in June 2017. It is also the metro that shows how local Colorado roofing rules really are. Fort Collins, 30 miles away, requires Class 4 impact-resistant shingles whenever half a roof or more is replaced. Greeley does not, and neither does Weld County. And the two are on different code editions, the city on the 2021 codes and the unincorporated county on the 2024 ones. One thing is about to change: from 1 January 2027 Greeley will require contractors to hold a City of Greeley licence before they can even apply for a permit.
What a Greeley roof is up against
The hail record here is the story. Across 2016 to 2025 Weld County logged 431 hail reports, 374 of them an inch or larger, against 109 severe thunderstorm and high wind reports and 34 tornado events. Counting hail reports alone, July leads with 116, then June with 106 and May with 81, so this is a high-summer season driven by afternoon storms coming off the Front Range. The largest stone on the local record is 4.25 inches, near Pierce on 12 June 2017, logged by NWS Boulder, and the busiest single day in the decade was 29 July 2016 with 29 separate reports. Reported property damage over the period is recorded as only $545,500, but that reflects how patchily NOAA’s damage fields are completed rather than an absence of losses: hail damage to roofs and vehicles is routinely logged as a report with no dollar figure attached.
The Class 4 question is where Greeley differs from its neighbour, and it is worth being precise because the answer is counterintuitive. The City of Fort Collins requires Class 4 impact-resistant shingles, tested to UL 2218, on the replaced portion whenever 50 percent or more of a roof is replaced, under a local amendment to code section R905.2.4.2. Greeley has no equivalent requirement. It adopted the 2021 International Codes with local amendments by Ordinance No. 25, 2022, effective 1 January 2023, and neither the base 2021 code nor Greeley’s or Weld County’s published code pages carry an impact-resistance mandate; the Colorado Roofing Association names only Larimer County and Fort Collins as having one. One honest limitation: we could not retrieve Appendix A of that ordinance, the schedule of local amendments, so this rests on Greeley’s and Weld’s own published code pages rather than on the amendment text itself. Either way the practical advice is the same in the county with the worst hail record in this batch: Class 4 is probably the right choice here, but in Greeley it is your decision rather than the permit desk’s, so it has to be specified and priced deliberately.
Two code and licensing changes are landing. Weld County adopted the 2024 International Codes for unincorporated areas effective 15 June 2026, a newer edition than the city’s 2021 codes, so a house just outside the Greeley limits is now inspected against a later code than one inside them. And Colorado has no state contractor licence, which until now has meant Greeley had no licence requirement either; the city announced on 10 August 2026 that from 1 January 2027 contractors must hold a City of Greeley licence before applying for permits, covering all trades including specialty trades. The licence classes and which one will cover roofing are not published anywhere we could reach, so if you are planning work over the turn of the year, ask the city directly which class your contractor will need and whether they have applied. Weld County itself requires state licence numbers on permit applications only for plumbing and electrical work, not roofing.
Colorado does give roofing customers statutory protections that most states do not, and in a hail market they are the rules worth knowing. Under C.R.S. 6-22-104, where the work is to be paid from insurance proceeds, you may rescind the contract within 72 hours of receiving written notice that the insurer has denied the claim in whole or in part, and the contractor must return your deposit within ten days less the value of work actually performed. C.R.S. 6-22-103 requires the contract to carry a rescission clause giving a full deposit refund within 72 hours of signing, and separately requires a statement in bold-faced type on the face of the contract that the contractor will hold your payment in trust until materials are delivered or a majority of the work is done. And under C.R.S. 6-22-103(1)(g) with 6-22-105, a roofing contractor cannot pay, waive or rebate any part of your insurance deductible. In a county that takes this much hail, a contractor offering to absorb your deductible is offering something state law forbids.

1. T Bare Roofing — TRB Score 84.8
T Bare Roofing is based in Greeley, CO, in business since 2017, led by Travis Bare, Owner, BBB accredited since 6 July 2020, A+ rating; business start date 2017, and holds Master Elite standing on the GAF certification registry.
Certifications held: Master Elite (GAF), Colorado Roofing Association contractor member, BBB Torch Award for Ethics 2025, Greeley Area Chamber of Commerce member. Certification by more than one manufacturer is uncommon and requires meeting each programme’s separate standards for insurance, training and track record.

What they actually do. Residential and commercial roofing in asphalt shingle, metal and tile, TPO, roof coatings, gutters, sheet metal and solar.
Why it ranks here. The clear leader and the only genuinely Greeley-centred firm in the top three: 4.9 across 468 reviews, the deepest customer record in the metro, with every detail of its identity agreeing across the state register, the BBB, the Colorado Roofing Association and the Greeley chamber. Two credentials stand out. It is a CRA contractor member with current liability and workers’ compensation cover published on the association’s own page, which is a live insurance check you can make yourself, and it won the Better Business Bureau’s Torch Award for Ethics in 2025, which is an assessed award rather than a self-declared badge.
Best fit for: The default first call in Weld County, and the widest material range locally including tile and solar.
What we would want clarified. It is eight years old, formed in November 2017, so it has less history than several firms below it. It publishes no municipal licence number, though Greeley requires none until January 2027, and it holds Master Elite rather than the top President’s Club tier. No non-GAF manufacturer certification appears on its site. 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 (970) 402-2285, 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. Green Top Roofing — TRB Score 76.5
Green Top Roofing is based in Loveland, CO, in business since 2013, led by Luke Burroughs, Northern Colorado branch manager; Brian Trainor and Adam Trainor are recorded by the BBB as partners of the parent business, BBB accredited since 25 July 2014, A+ rating, filed under the former 970 Services name; business start date 7 October 2013, and holds Master Elite standing on the GAF certification registry.
Certifications held: Master Elite (GAF), Greeley Area Chamber of Commerce member, Fort Collins Area Chamber of Commerce member. Certification by more than one manufacturer is uncommon and requires meeting each programme’s separate standards for insurance, training and track record.

- Green Top Roofing is a registered trade name, master trade name ID 20241512530, effective 6 May 2024.. Colorado Secretary of State trade name register
- The registrant, 970 Companies LLC, entity ID 20131561829, is a Colorado limited liability company formed 27 September 2013.. Colorado Secretary of State business entity register
What they actually do. Residential and commercial roofing, storm restoration, and fire and water damage restoration across Larimer, Weld and Boulder counties.
Why it ranks here. Weld County coverage is published rather than assumed: its Northern Colorado page states the branch serves Larimer, Weld and Boulder counties and names Greeley, Windsor and Evans specifically, and it is a member of the Greeley Area Chamber as well as the Fort Collins one. Twelve years of trading with BBB accreditation since 2014 at A+, the longest continuous accreditation among the Greeley firms ranked here, and it states it has former insurance adjusters on staff, which is directly relevant in the county with this hail record. It also appears on our Fort Collins ranking, where it placed fourth; the business sits in Loveland, between the two metros, and genuinely serves both.
Best fit for: Hail claims, and homeowners who want a firm working both the Greeley and Fort Collins ends of Northern Colorado.
What we would want clarified. The name is newer than the business. Green Top Roofing was registered as a trade name only on 6 May 2024, by 970 Companies LLC, and the BBB record still sits under the former 970 Services branding, so a search under the current name returns a shorter history than the firm actually has. It is based in Loveland, in Larimer County, rather than in Weld, and no founding year, ownership or street address appears on its own site, whose about page returns an error. It publishes no manufacturer credential outside GAF. We publish this because a ranking that only prints the flattering findings is an advertisement, not an assessment.

Northern Lights Exteriors is based in Fort Lupton, CO, in business since 2001, led by James Hooven, President, BBB accredited since 28 April 2010, A+ rating; BBB records a 2001 founding, and holds Master Elite standing on the GAF certification registry.

What they actually do. Roofing, siding, replacement windows, gutters, exterior painting and decks.
Why it ranks here. The most explicit Weld County coverage of any firm here: its service areas page carries a Weld County heading listing Greeley, Johnstown, Milliken, Firestone, Frederick, Fort Lupton and Windsor, and its own registered address is on Weld County Road 23. It is the longest BBB-accredited contractor on this page, since April 2010 at A+, and the only one holding a second manufacturer’s top-tier credential, as a James Hardie Elite Preferred contractor since 2011 and a President’s Club winner with that manufacturer, which matters if you are doing siding alongside the roof.
Best fit for: A roof and siding job together, and homeowners in southern Weld County around Fort Lupton and Firestone.
What we would want clarified. Its stated founding year does not match the state record: the company gives 2001 and the BBB agrees, but the Colorado Secretary of State shows the limited liability company formed on 26 April 2010, so 2001 describes the business rather than the entity. It publishes a licence number, C120350, without naming the issuing jurisdiction, and we could not match it to any Colorado municipality, so treat it as unverifiable rather than as a credential. Roofing is one of six service lines, and its base in Fort Lupton is at the far southern end of the county, about 30 miles from Greeley.

- Accredited since 25 October 2018 with an A+ rating, business start date 27 January 2017, zero complaints closed in the last three years.. BBB business profile
What they actually do. Residential and commercial roof repair and replacement, storm damage restoration, asphalt shingles, metal and flat roofing, and seamless gutters.
Why it ranks here. One of only two contractors ranked here actually based in Greeley, at an 8th Avenue address that matches on both the state register and the BBB. Master Elite certification, accredited at A+ since 2018 with no complaints closed in the last three years, and owner-run with a named owner and office manager, which is more than several larger firms on this page publish.
Best fit for: A Greeley homeowner who wants a small, locally based firm with a clean complaint record.
What we would want clarified. Its 19 reviews are by far the thinnest customer record on this page, so the 4.6 rating rests on very little. Its own site claims the business dates to 1991, which the state register and the BBB both contradict with a formation date of 27 January 2017, so treat the earlier date as unsupported. It publishes no manufacturer credential outside GAF and no municipal licence. We publish this because a ranking that only prints the flattering findings is an advertisement, not an assessment.

What they actually do. Hail damage restoration, roof repair and replacement, water and fire damage restoration, mould remediation, asbestos abatement and reconstruction.
Why it ranks here. The widest capability on this page and the deepest institutional record: BBB accredited since September 2005, the longest of any Greeley firm here, with 4.6 across 336 reviews, membership of both the Greeley and Windsor chambers, and an address that the state register, the BBB and both chambers record identically. It is a full restoration contractor rather than a roofer, covering water and fire damage, mould remediation, asbestos abatement and reconstruction alongside hail work, and it leads with hail damage restoration as a named service.
Best fit for: Hail damage that let water into the house, and any loss needing remediation and reconstruction as well as a new roof.
What we would want clarified. Roofing is one line in a restoration business, so ask who actually does the roof and whether the crew is employed or subcontracted. It is based in Windsor, on the Larimer and Weld county line rather than in Greeley, and its BBB profile is filed under fire and water damage restoration rather than roofing.

What 4.25 inch hail does to a Greeley 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 1 county of the Greeley, CO statistical area over ten years, with the dates, the stone sizes and the towns they landed on. Over that decade the metro logged 431 hail reports, 109 severe thunderstorm and high wind reports and 34 tornadoes. Reported property damage from hail, severe wind and tornado over that decade totalled $546,000; flood and winter-storm losses are counted separately and are not included.
The biggest hail to fall on Greeley in a decade
| Date | Stone size | Reported near | County |
|---|---|---|---|
| 12 June 2017 | 4.25 in | Pierce | Weld |
| 13 July 2023 | 3.25 in | Stoneham | Weld |
| 20 May 2021 | 3.25 in | Stoneham | Weld |
| 12 June 2017 | 3.0 in | Hereford | Weld |
| 12 September 2019 | 3.0 in | Stoneham | Weld |
| 20 May 2021 | 3.0 in | Stoneham | Weld |
The largest stone on record for this metro fell on 12 June 2017 near Pierce, measured at 4.25 inches. That is grapefruit sized. Stones that big destroy asphalt shingles outright, dent metal, crack tile and routinely total roofs across whole neighbourhoods.
Wind. The strongest thunderstorm gust logged in the metro was 78 knots, about 90 mph, near La Salle on 20 June 2024. Asphalt shingles begin lifting at roughly 67 mph when they are correctly nailed, and considerably below that when they are not.
Tornadoes. 34 tornadoes touched down in these counties over the decade, the strongest rated EF2 near Masters on 7 May 2016.
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 6 June 2020 event near Rockport, reproduced verbatim:
A combination of an upper level trough moving northwest across the state, coupled with a strong surface pressure gradient, led to numerous reports of high wind gusts across the region. Most of the wind damage occurred with the passage of a rare derecho; a large fast-moving complex of thunderstorms with powerful straight-line winds. In addition, strong wind gusts from 59 to 71 mph not associated with the derecho, occurred prior to and following the passage of this system over the urban corridor and plains of northeast Colorado. By midday the derecho, which originated over the Great Basin, moved over the northern and central mountains, and then rapidly northeast across the I-25 corridor by…
That is what the specification has to anticipate here, written up by the agency that recorded it rather than by a contractor selling the repair.
When it happens. Severe weather reports cluster in July (161), June (138), May (110). The worst years on record were 2019 (88), 2025 (84), 2018 (77). If you are scheduling non-urgent work in Greeley, 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. At 374 damaging-hail reports in ten years, impact resistance in Greeley is a specification question, not an upsell. Ask every contractor you shortlist to quote a UL 2218 Class 4 impact-rated shingle alongside the standard option, and ask your insurer whether a Class 4 roof earns a premium discount, because many carriers offer one in high-hail territory.
What a Greeley homeowner should ask for in writing
There is no state roofing licence in CO. Colorado issues no statewide roofing licence. The Department of Regulatory Agencies does not licence roofers at all. Licensing and permitting happen entirely at city and county level, and requirements differ sharply between jurisdictions.
Denver requires a Specialty Class D certificate to roof, and to obtain one an individual must first hold a Supervisor Certificate and document two years of field experience across at least 24 projects in 24 different months. Denver grants no reciprocity with other counties or states.
That absence is the most important fact on this page. Where a state issues no credential, a manufacturer certification that can be revoked is the only quality signal a homeowner can actually check, which is why this ranking is built on certification rather than star ratings.
Check here: Denver Community Planning and Development contractor licensing. Confirm the contractor holds a licence for the specific municipality your home sits in, and that they, not you, pull the roofing permit.
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 many certified roofers Greeley actually has
7 certified roofing contractors serve the principal cities of the Greeley, CO statistical area, of which 0 hold the top President’s Club tier. The pool carries 1,521 customer reviews between them at a mean rating of 4.85. The statistical area had a 2024 population of 369,745, a change of 12.39% against the 2020 census base, per the U.S. Census Bureau Vintage 2024 estimates.
How these Greeley rankings were produced
Every contractor in the Greeley, CO 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 7 certified contractors, of whom 0 hold President’s Club standing and 5 Master Elite, against a metro mean rating of 4.85. The top five were then researched individually against Better Business Bureau records, state licence registers and manufacturer directories. The findings are printed above whether they flatter the contractor or not, and nobody paid to appear.
Set aside in Greeley. A contractor that would otherwise have scored into the top five was removed for the reason stated. The score is computed from public data, but where the research pass finds evidence undermining an input to that score, the score is set aside.
- Sweet Roofing, which scored 72.2: scored fifth on a clean 5.0, is BBB accredited at A+, is a Colorado Roofing Association contractor member and won the association’s first-place award for outstanding workmanship in 2019. It is excluded on geography alone. Greeley is not in its published service area: its own site lists sixteen locations, Erie, Frederick, Firestone, Longmont, Loveland, Arvada, Boulder, Lyons, Fort Lupton, Thornton, Westminster, Broomfield, Littleton, Lakewood and Denver in Colorado plus Pocatello, Idaho, and names neither Greeley, Evans nor Windsor. It plainly does work inside Weld County, since Frederick, Firestone and Fort Lupton are all in the county’s southern end and its own registered address is in Frederick, but its centre of gravity is the Denver and Boulder side of the county rather than the Greeley end. Note also that its own site dates the business to 1983 and describes a third generation, while the Colorado trade name register shows Sweet Roofing registered on 12 January 2018 to Pat Sweet, LTD., a corporation formed on 1 January 2018, which the BBB corroborates. It may well quote a Greeley job on request, and on this record it would be worth asking

Common questions about roofers in Greeley
Who is the best roofer in Greeley, CO?

It holds Master Elite certification with a 4.9 rating across 468 reviews. Highest-scoring is not the same as best fit for your specific job, and the four companies behind it score within 13.5 points.
How many certified roofing contractors serve Greeley?
7 contractors on the GAF certification registry serve the principal cities of the Greeley, CO statistical area as of September 2026, of which 0 hold President’s Club status.
How much damaging hail does Greeley get?
The Greeley, CO statistical area recorded 374 hail reports of 1 inch or larger and 54 of 2 inches or larger between 2016 and 2025 in the NOAA Storm Events Database. The largest hailstone reported measured 4.25 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 Greeley in the last ten years?
The largest hailstone logged by the National Weather Service in the Greeley, CO statistical area between 2016 and 2025 measured 4.25 inches, reported near Pierce on 12 June 2017. That is grapefruit sized. Stones that big destroy asphalt shingles outright, dent metal, crack tile and routinely total roofs across whole neighbourhoods. Across the decade the metro recorded 431 hail reports. Reported property damage from hail, severe wind and tornado over that decade totalled $546,000; flood and winter-storm losses are counted separately and are not included.
When is the worst time of year for roof damage in Greeley?
Severe-weather reports in the Greeley, CO statistical area cluster in July, June, May, on the NOAA record for 2016 to 2025. If the work can wait, booking outside that window usually buys you shorter lead times and more of the contractor’s attention.
Do roofers need a licence in CO?
Colorado issues no statewide roofing licence. The Department of Regulatory Agencies does not licence roofers at all. Licensing and permitting happen entirely at city and county level, and requirements differ sharply between jurisdictions. Denver requires a Specialty Class D certificate to roof, and to obtain one an individual must first hold a Supervisor Certificate and document two years of field experience across at least 24 projects in 24 different months. Denver grants no reciprocity with other counties or states.
What should I check before hiring a roofer in Greeley?
Confirm the contractor holds a licence for the specific municipality your home sits in, and that they, not you, pull the roofing permit.
Is Greeley a hard market to find a good roofer in?
Weld County is the most hail-exposed metro in this programme’s recent batches: 431 hail reports over the decade, 374 of them an inch or larger, with a 4.25 inch stone near Pierce in June 2017. It is also the metro that shows how local Colorado roofing rules really are. Fort Collins, 30 miles away, requires Class 4 impact-resistant shingles whenever half a roof or more is replaced. Greeley does not, and neither does Weld County. And the two are on different code editions, the city on the 2021 codes and the unincorporated county on the 2024 ones. One thing is about to change: from 1 January 2027 Greeley will require contractors to hold a City of Greeley licence before they can even apply for a permit.
Why is Sweet Roofing not on this list?
Scored fifth on a clean 5.0, is BBB accredited at A+, is a Colorado Roofing Association contractor member and won the association’s first-place award for outstanding workmanship in 2019. It is excluded on geography alone. Greeley is not in its published service area: its own site lists sixteen locations, Erie, Frederick, Firestone, Longmont, Loveland, Arvada, Boulder, Lyons, Fort Lupton, Thornton, Westminster, Broomfield, Littleton, Lakewood and Denver in Colorado plus Pocatello, Idaho, and names neither Greeley, Evans nor Windsor. It plainly does work inside Weld County, since Frederick, Firestone and Fort Lupton are all in the county’s southern end and its own registered address is in Frederick, but its centre of gravity is the Denver and Boulder side of the county rather than the Greeley end. Note also that its own site dates the business to 1983 and describes a third generation, while the Colorado trade name register shows Sweet Roofing registered on 12 January 2018 to Pat Sweet, LTD., a corporation formed on 1 January 2018, which the BBB corroborates. It may well quote a Greeley job on request, and on this record it would be worth asking.
