Short answer: As of October 2026, the five highest-scoring roofing contractors in the Green Bay, WI metro on The Roofing Brief Contractor Score are Weather-Tite Exteriors LLC (79.9), Overhead Solutions Inc (70.8), H and S Roofing LLC (68.2), Prestige Roofing LLC (66.9), Exterior Solutions LLC (55.2). All of them carry a verifiable manufacturer certification, every rating here was cross-checked against an independent record, and no money changed hands for any placement.
The Roofing Brief scored 7 certified roofing contractors serving the Green Bay metro on a published, reproducible formula, then researched each of the top five individually to confirm its record. Green Bay is the metro where nobody checks. The City of Green Bay does not require a permit for a straightforward residential reroof, Brown County runs no county-wide building inspection department at all, and Wisconsin has no state roofing licence and no state trade examination for roofers. What Wisconsin does have is a two-part credential, a Dwelling Contractor certification held by the business and a Dwelling Contractor Qualifier held by an individual, and under SPS 305.31 nobody can even obtain a building permit for a one or two family dwelling without both. Neither involves a roofing exam. So the one technical requirement that genuinely protects a Green Bay roof, the ice dam membrane at the eaves, is installed on trust, and none of the six contractors here publishes either certification number.
The conditions a Green Bay roof has to be specified for
The severe-weather record is mild and beside the point. Across 2016 to 2025 Brown, Oconto and Kewaunee counties logged 59 hail reports against 131 severe thunderstorm and high wind reports and 7 tornado events, with $1.01 million in reported property damage. Counting severe-weather reports of every kind together, July leads with 59, then June with 45 and August with 39. What actually destroys roofs here does not appear in that record at all, because snow and ice are not severe-weather reports. Green Bay Austin Straubel International Airport carries a normal annual snowfall of 51.4 inches under NOAA’s 1991 to 2020 normals, with December at 13.1 inches and January at 13.0 the snowiest months. The failure mode is water backing up behind a ridge of ice in February, not impact in July.
Wisconsin’s credential system is unusual and worth understanding, because the thing it does not test is roofing. Under Wis. Admin. Code SPS 305.31, no person may obtain a building permit for a one or two family dwelling unless they hold both a Dwelling Contractor certification and a Dwelling Contractor Qualifier certification. The Dwelling Contractor certification is the business-level credential, held by an owner, partner or chief executive, and it is tied to insurance rather than skill. The Qualifier is the individual credential, and it requires completing at least twelve hours of an approved initial qualifier course in dwelling construction, with no trade examination. So there is no state roofing licence to ask about and no roofing exam behind either credential. The two things worth asking for are the company’s Dwelling Contractor certification number and the name and number of the individual holding its Qualifier certification. None of the six contractors in this metro publishes either, and we could not reach the state lookup to search them, so this is the gap on this page rather than a finding against any firm.
Permitting adds very little oversight here. The City of Green Bay’s own permit list records residential roofing with no structural changes as not requiring a permit, and where a roofing permit is required the fee is a flat amount rather than a percentage of the job. Brown County has no county-wide building inspection department for the metro: permits are issued by each city, village and town separately. The residential code in force is the Wisconsin Uniform Dwelling Code at SPS 320 to 325, which applies statewide to the design and construction of one and two family dwellings regardless of who administers the permit. Snow load is set by a zone map under SPS 321.02(1)(b) rather than by a single statewide figure.
Wisconsin does regulate the money, and the statute is a good one to know. Wis. Stat. 100.65, created by 2013 Wisconsin Act 24 and effective 1 January 2014, prohibits a residential contractor from offering to pay, waive or rebate all or part of an insurance deductible, including in advertising. So a Green Bay contractor offering to absorb your deductible after a storm is offering something state law specifically forbids. The median year built in Brown County is 1985, with Oconto at 1981 and Kewaunee at 1970, which matters for the eave detail: a house from 1985 predates the current self-adhering membrane language in the Wisconsin code, so on a typical reroof here the ice dam protection is being installed to the modern standard for the first time.

1. Weather-Tite Exteriors LLC — TRB Score 79.9
Weather-Tite Exteriors LLC is based in Green Bay, WI, in business since 1990, led by Jesse A. Geurts, Partner, BBB accredited, A+ rating; founding recorded as 1990, and holds Master Elite standing on the GAF certification registry.

Independently corroborated:
- Accredited with an A+ rating, recording the founding as 1990, which matches the company’s own account.. BBB business profile
- GAF lists Weather-Tite Exteriors LLC of Green Bay, WI in its residential contractor directory at Master Elite level.. GAF contractor directory
What they actually do. Residential and commercial roofing, re-roofing and repair, ice dam removal, roof and exterior cleaning, gutters and gutter guards, across Brown, Door, Kewaunee, Outagamie and Oconto counties.
Why it ranks here. The top score in the metro and the only Master Elite contractor in it, on a clean 5.0 across 131 reviews, with its founding year agreeing between its own account and the BBB at 1990, making it the longest-established firm here at 35 years. Its published service area spans all three counties of this metro. It is also the only contractor on this page offering ice dam removal as a named service, which given everything above is the service most likely to be needed in February.
Best fit for: The default first call in Brown County, and the firm to ring when ice is already forming at the eaves.
What we would want clarified. It publishes neither a Wisconsin Dwelling Contractor certification number nor a Qualifier number, though no contractor in this metro does and we could not reach the state lookup to check. It holds no manufacturer credential outside GAF, and its 131 reviews are a modest base next to the larger operators below it. 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 (920) 336-6162, 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. Overhead Solutions Inc — TRB Score 70.8
Overhead Solutions Inc is based in Suamico, WI, in business since 2010, led by Paul Collins, President and Owner, with Tara Collins named as co-founder, BBB accredited, A+ rating, and holds Certified standing on the GAF certification registry.

What they actually do. Asphalt shingle roofing, flat and rubber roofing, metal standing seam and metal re-roofs, cedar shake, pole building roofs, winter roof preparation and roof snow removal.
Why it ranks here. Despite the name this is a roofing contractor rather than a garage door company: the BBB categorises it under roofing contractors and its published services are entirely roofing and exterior work. It carries much the deepest customer record in the metro at 1,563 reviews on a 4.9 rating, and the widest materials range on this page, covering cedar shake, pole buildings, metal standing seam and rubber flat roofs. It publishes winter roof preparation and roof snow removal as distinct services, which in a 51 inch snowfall climate is a meaningful line to offer.
Best fit for: Cedar shake, metal or pole-building roofs, and winter snow removal before the ice forms.
What we would want clarified. Read the review count in context. It is a company-wide, multi-office figure covering three Wisconsin locations at Suamico, Eagle River and Port Washington with service areas reaching Wausau and Wisconsin Rapids, so it is not a Green Bay roofing-only number and is not comparable with the single-location firms it sits next to. It holds base-tier GAF Certified status rather than Master Elite, publishes no manufacturer credential outside GAF, and we could not read its own website, which refused our requests, so its record here rests on the BBB. We publish this because a ranking that only prints the flattering findings is an advertisement, not an assessment.

3. H and S Roofing LLC — TRB Score 68.2
H and S Roofing LLC is based in Green Bay, WI, in business since 2000, led by Paul A. Saharsky, Owner, with Jake Weiner also named as an owner on the company site, Not accredited, A+ rating; BBB records a 1992 founding against the company’s own 2000, and holds Certified standing on the GAF certification registry.
Certifications held: Certified (GAF), Atlas preferred and certified installer, Owens Corning certified installer, IKO certified installer, Brown County Home Builders Association member since 2003, NFIB member since 2020. Certification by more than one manufacturer is uncommon and requires meeting each programme’s separate standards for insurance, training and track record.

- Member since 2003, listed in the association’s own directory.. Brown County Home Builders Association

What they actually do. Residential roof replacement, repair and tear-offs, gutters and downspouts, new construction roofing, and skylight work.
Why it ranks here. By far the best-credentialed contractor in this metro outside GAF: certified installer standing with three separate manufacturers, Atlas, Owens Corning and IKO, where every other firm here publishes none. It is also a Brown County Home Builders Association member since 2003, which is a dated, checkable affiliation in a metro where the county association maintains the main contractor directory. It carries 4.9 across 313 reviews.
Best fit for: Homeowners who want a choice of shingle manufacturer rather than a single-brand installer, and new construction work.
What we would want clarified. Its founding year is unresolved: its own About page dates the business to 2000 while the BBB records 1992, and we could not settle it because Wisconsin’s corporate register refused our requests. Its BBB profile is not accredited despite the A+ rating. It holds base-tier GAF Certified status rather than Master Elite, and like every firm here it publishes no Dwelling Contractor or Qualifier certification number.

4. Prestige Roofing LLC — TRB Score 66.9
Prestige Roofing LLC is based in De Pere, WI, in business since 2015, led by Jorge Suarez, Owner and Production Manager, with Federico Suarez as co-owner, Not accredited, A+ rating; founding independently recorded as 16 March 2015, and holds Certified standing on the GAF certification registry.

Independently corroborated:
- Listed as a member with Jorge Suarez as the named contact.. Brown County Home Builders Association
- Rated A+ though not accredited, with the founding date independently recorded as 16 March 2015, matching the company’s own account.. BBB business profile
What they actually do. Asphalt shingle roofing, roof replacement and repair, siding and insulation.
Why it ranks here. A father and son business founded in 2015 by Federico and Jorge Suarez, describing itself as veteran-owned, with the founding date independently confirmed by the BBB rather than merely claimed. It holds Atlas Pro Plus certification alongside GAF and is a Brown County Home Builders Association member with a named contact. Insulation among its published services is relevant here, because attic heat loss rather than the roof covering is what causes ice dams in the first place.
Best fit for: A reroof combined with attic insulation work, which addresses the cause of ice damming rather than the symptom.
What we would want clarified. Its published service area covers Brown, Door, Oconto and Shawano counties but not Kewaunee, one of this metro’s three counties, so confirm coverage if you are on that side. It runs a second office in Wausau, well outside the metro. Its BBB profile is not accredited, it holds base-tier GAF Certified status, and it publishes no Dwelling Contractor or Qualifier number.

What they actually do. Residential roofing and siding.
Why it ranks here. A small family-owned roofing and siding firm in De Pere, founded by Dustin Marks, with its 2015 incorporation independently recorded by the BBB.
Best fit for: A straightforward shingle replacement from a small local firm, if you do your own verification first.
What we would want clarified. This is the thinnest entry on the page and we are flagging it rather than dressing it up. Its 61 reviews at 4.7 are the second-smallest and lowest-rated record here. Its own website was serving an under-construction placeholder when we looked, so nothing above comes from the company itself and we could not establish its service area at all. Its BBB profile is not accredited and the file was opened only in December 2025. It publishes no manufacturer credential outside GAF and no Wisconsin certification numbers.

The 131 wind reports that shape a Green Bay 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 3 counties of the Green Bay, WI statistical area over ten years, with the dates, the stone sizes and the towns they landed on. Over that decade the metro logged 59 hail reports, 131 severe thunderstorm and high wind reports and 7 tornadoes. Reported property damage from hail, severe wind and tornado over that decade totalled $1.0 million; flood and winter-storm losses are counted separately and are not included.
The biggest hail to fall on Green Bay in a decade
| Date | Stone size | Reported near | County |
|---|---|---|---|
| 7 September 2021 | 2.5 in | Wrightstown | Brown |
| 7 September 2021 | 2.0 in | Wrightstown | Brown |
| 7 September 2021 | 1.75 in | Tisch Mills | Kewaunee |
| 7 August 2019 | 1.5 in | Oconto | Oconto |
| 7 September 2021 | 1.5 in | Greenleaf | Brown |
| 7 September 2021 | 1.5 in | Little Rapids | Brown |
The largest stone on record for this metro fell on 7 September 2021 near Wrightstown, measured at 2.5 inches. That is hen-egg sized. Two inches is the threshold at which insurers expect functional damage and full replacement claims.
Wind. The strongest thunderstorm gust logged in the metro was 70 knots, about 81 mph, near Klondike on 19 July 2019. Asphalt shingles begin lifting at roughly 67 mph when they are correctly nailed, and considerably below that when they are not.
Tornadoes. 7 tornadoes touched down in these counties over the decade, the strongest rated EF1 near Underhill on 25 June 2024.
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 15 June 2022 event near Ashwaubenon, reproduced verbatim:
Thunderstorm winds downed numerous trees on the west side of Green Bay. The time of this report is an estimate based on radar data.
That is the kind of damage a roof in this metro has to be specified against, described by the agency that recorded it rather than by a contractor selling the repair.
When it happens. Severe weather reports cluster in July (59), June (45), August (39). The worst years on record were 2021 (32), 2017 (30), 2019 (27). If you are scheduling non-urgent work in Green Bay, 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 Green Bay. Weight your decision toward wind rating, ventilation and flashing detail rather than paying extra for impact-rated shingles.
The one detail that decides whether a Green Bay roof survives February
An ice dam is a ridge of ice that forms at the lower edge of a roof and blocks meltwater from draining off. The National Weather Service describes the mechanism plainly: heavy snow on the roof melts during the day and then refreezes when temperatures fall, and the water pooling behind the resulting ridge works its way back up under the shingles and into the house. The important point is that the cause is heat escaping from the house into the attic, not the gutters. In a correctly built roof, insulation prevents heat loss from the interior and venting keeps the attic air cold enough to minimise the freeze and thaw cycle at the eaves. Gutter heat cable treats a symptom.
Wisconsin addresses the symptom at the eaves, and the code is specific enough to hold a contractor to. Wis. Admin. Code SPS 321.28(4)(a) requires that shingled or shake roofs extending over a heated area of a dwelling or attached garage, with a slope of 4:12 or less, be provided with ice dam protection. Note that threshold: the requirement is written for roofs of 4:12 or shallower that extend over heated space, so it is not a blanket rule for every pitched roof in the state. A Green Bay homeowner with a steeper roof should treat the membrane as a strongly advisable upgrade rather than assume it is mandatory, and should ask the contractor to say which it is on their roof.
Where it does apply, SPS 321.28(4)(b) fixes the extent by two separate tests and the installer has to satisfy both: the ice dam protection must extend at least 30 inches up the roof slope from the roof edge, and at least 12 inches up the roof slope beyond the interior face of the exterior wall. On a house with a deep overhang the second test governs and the first is not enough on its own, which is exactly the detail that gets missed when nobody inspects the work. Underlayment generally is set by SPS 321.28(2), which requires number 15 asphalt-impregnated felt or an equivalent type I material showing no water transmission when tested.
Put the three facts together and the Green Bay position is clear. The code sets a real, measurable requirement at the eaves. The city does not require a permit for a straightforward reroof, so no inspector will check it. And the state credential a contractor must hold to pull a permit at all involves a twelve-hour course rather than a roofing examination. The practical defence is to write the membrane into the contract by its code reference, specify how far up the slope it runs past the interior face of the exterior wall, and ask for a photograph of it in place before the shingles go on. That costs nothing and it is the only inspection your roof is likely to get.
What Wisconsin requires at the eaves, and who checks it
| Requirement | Source | Who verifies it |
|---|---|---|
| Ice dam protection on shingled roofs of 4:12 or less over heated space | Wis. Admin. Code SPS 321.28(4)(a) | Nobody, on a Green Bay reroof with no structural change |
| At least 30 inches up the slope from the roof edge | SPS 321.28(4)(b) | The contractor |
| At least 12 inches up the slope beyond the interior face of the exterior wall | SPS 321.28(4)(b) | The contractor |
| Underlayment of number 15 felt or equivalent type I material | SPS 321.28(2) | The contractor |
| Dwelling Contractor certification plus Qualifier certification to pull any permit | SPS 305.31 | The permit office, where a permit is required |

How to tell a Green Bay roofer’s claims from their record
Licensing is required in WI. Wisconsin does not issue a roofing-specific licence, but anyone pulling a building permit for residential work must hold a Dwelling Contractor certification from the Department of Safety and Professional Services, and the company must also hold or employ a Dwelling Contractor Qualifier.
The Qualifier credential requires at least 12 hours of an approved course in dwelling construction, with course tests, and renews every two years on 12 hours of continuing education; the code describes its purpose as proof of continuing education rather than trade competence. The business certification requires a bond of at least $25,000 or liability insurance of at least $250,000 per occurrence. Under Wis. Stat. 100.65 a contractor may not promise to pay or rebate your insurance deductible, may not negotiate your claim for you, and must give you a cancellation form; you may cancel within three business days of a written claim denial. Each violation carries a forfeiture of $500 to $1,000.
Check here: Wisconsin DSPS credential search. Ask for both credentials: a Dwelling Contractor certification without a Qualifier cannot legally pull your permit. The Uniform Dwelling Code requires ice dam protection only on roofs of 4:12 slope or less over heated space, running at least 30 inches up the slope and 12 inches past the inner face of the wall, so on steeper roofs it is a choice, not a rule.
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 Green Bay rankings were produced
Every contractor in the Green Bay, WI 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 1 Master Elite, against a metro mean rating of 4.629. The top five were then researched individually against Better Business Bureau records, state licence registers and manufacturer directories. Good and bad findings are published together, and no contractor paid for a place here.

How many certified roofing contractors serve Green Bay?
7 contractors on the GAF certification registry serve the principal cities of the Green Bay, WI statistical area as of October 2026, of which 0 hold President’s Club status.
How much damaging hail does Green Bay get?
The Green Bay, WI statistical area recorded 35 hail reports of 1 inch or larger and 2 of 2 inches or larger between 2016 and 2025 in the NOAA Storm Events Database. The largest hailstone reported measured 2.5 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 Green Bay in the last ten years?
The largest hailstone logged by the National Weather Service in the Green Bay, WI statistical area between 2016 and 2025 measured 2.5 inches, reported near Wrightstown on 7 September 2021. That is hen-egg sized. Two inches is the threshold at which insurers expect functional damage and full replacement claims. Across the decade the metro recorded 59 hail reports. Reported property damage from hail, severe wind and tornado over that decade totalled $1.0 million; flood and winter-storm losses are counted separately and are not included.
When is the worst time of year for roof damage in Green Bay?
Severe-weather reports in the Green Bay, WI statistical area cluster in July, June, August, on the NOAA record for 2016 to 2025. Scheduling discretionary work away from that window tends to get you a better crew and a faster start, because nobody is juggling emergency callouts.
Do roofers need a licence in WI?
Wisconsin does not issue a roofing-specific licence, but anyone pulling a building permit for residential work must hold a Dwelling Contractor certification from the Department of Safety and Professional Services, and the company must also hold or employ a Dwelling Contractor Qualifier. The Qualifier credential requires at least 12 hours of an approved course in dwelling construction, with course tests, and renews every two years on 12 hours of continuing education; the code describes its purpose as proof of continuing education rather than trade competence. The business certification requires a bond of at least $25,000 or liability insurance of at least $250,000 per occurrence. Under Wis.

Each violation carries a forfeiture of $500 to $1,000.
What should I check before hiring a roofer in Green Bay?
Ask for both credentials: a Dwelling Contractor certification without a Qualifier cannot legally pull your permit. The Uniform Dwelling Code requires ice dam protection only on roofs of 4:12 slope or less over heated space, running at least 30 inches up the slope and 12 inches past the inner face of the wall, so on steeper roofs it is a choice, not a rule.

Is Green Bay a hard market to find a good roofer in?
Green Bay is the metro where nobody checks. The City of Green Bay does not require a permit for a straightforward residential reroof, Brown County runs no county-wide building inspection department at all, and Wisconsin has no state roofing licence and no state trade examination for roofers. What Wisconsin does have is a two-part credential, a Dwelling Contractor certification held by the business and a Dwelling Contractor Qualifier held by an individual, and under SPS 305.31 nobody can even obtain a building permit for a one or two family dwelling without both. Neither involves a roofing exam. So the one technical requirement that genuinely protects a Green Bay roof, the ice dam membrane at the eaves, is installed on trust, and none of the six contractors here publishes either certification number.
Is wind or hail the bigger risk to a roof in Green Bay?
Wind, by a wide margin. The Green Bay, WI statistical area logged 131 severe thunderstorm and high wind reports against 35 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.
