Short answer: As of September 2026, the five highest-scoring roofing contractors in the Hartford-West Hartford-East Hartford, CT metro on The Roofing Brief Contractor Score are Millstream Construction (90.8), Rising Star Roofing LLC (90.4), J.P. Carroll Roofing, LLC (90.2), Turner Home Improvement Contractors, LLC (86.6), Turner & Sons Roofing & Siding, LLC (86.4). 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 10 certified roofing contractors serving the Hartford metro on a published, reproducible formula, then researched each of the top five individually to confirm its record. Hartford recorded zero damaging hail in the past decade. The roofing problem here is New England winter: ice damming, snow load and freeze-thaw at the eaves. Connecticut requires Home Improvement Contractor registration with the Department of Consumer Protection for any residential work above $200, so essentially every roofing job here requires a registered contractor. Commercial roofing requires a separate and higher major contractor registration. Notably, this metro has the deepest bench of genuinely old family firms in the programme, with two trading since the mid-1950s.
What a Hartford roof is up against
Connecticut gives homeowners a real backstop, and it is tied to registration. Every home improvement contractor, roofers included, must register with the Department of Consumer Protection, and registered contractors fund the Home Improvement Guaranty Fund, which can compensate a homeowner up to $25,000 for losses caused by a registered contractor. Hire someone unregistered and that protection does not exist. Hartford’s permit application asks for the contractor’s registration number along with the material, the number of layers being removed and the square footage, so the registration shows up twice in the paper trail.
The ice barrier requirement here is specific and generous, and it is worth checking on the quote. Connecticut’s building code requires ice barrier membrane on new roofs and re-roofing, running from the eave edge to at least 24 inches past the interior face of the exterior wall, with valleys protected at least 24 inches from the centreline on each side. That is the single most important detail on a Hartford roof, because the freeze and thaw cycle here reliably produces ice dams on any roof with a warm attic beneath it.
The storm record is modest but not empty: 256 severe wind reports, 49 hail reports and four tornadoes over the decade, peaking in July, with 2024 the busiest year. On 15 May 2018 tennis-ball hail of 2.5 inches smashed car windshields and house windows in Granby, and on 26 June 2024 the ASOS at Bradley International Airport recorded a 77 mph gust. Tornadoes are rare in the Connecticut River valley, though an EF1 crossed part of Tolland County in September 2019.
Connecticut’s storm data also comes with a caveat we correct for on these pages: the state replaced counties with planning regions in 2022, while the National Weather Service still files reports under the old county codes, so an uncorrected dataset shows zero hail for Hartford. It is not zero. The practical reading of the real record is that winter, not summer, sets the specification: ice barrier coverage, attic air sealing and ventilation, and gutters that drain before the next freeze.

What they actually do. Roof replacement, repair, inspection, storm damage, EPDM commercial roofing, gutters and siding.
Why it ranks here. EPDM capability covers the flat and low-slope sections common on New England additions and porches, which many shingle-only roofers subcontract out.
Best fit for: Homes with flat roof sections or additions.
What we would want clarified. Alongside strong ratings, some reviews report incomplete work and communication difficulties. Agree a written completion checklist before final payment. We publish this because a ranking that only prints the flattering findings is an advertisement, not an assessment.

3. J.P. Carroll Roofing, LLC — TRB Score 90.2

Independently corroborated:
- A+ rated and accredited since 1 August 2023, 39 years in business. BBB
- Rated 5.0 across multiple platforms with over 500 five-star reviews, serving Connecticut and Massachusetts. Reviews
What they actually do. Shingle, flat and slate roofing plus gutters and window replacement across Connecticut and Massachusetts.
Why it ranks here. 1,402 registry reviews is the deepest evidence base in the Hartford pool by a wide margin, from a firm trading nearly 40 years. Slate capability is genuinely uncommon and directly relevant on Hartford’s older housing stock.
Best fit for: Slate roofs, historic properties, and homeowners wanting the deepest review record in the metro.
What we would want clarified. BBB accreditation dates only from August 2023 despite 39 years of trading, so the accreditation record is far shorter than the company history. We publish this because a ranking that only prints the flattering findings is an advertisement, not an assessment.

What they actually do. Roofing, siding, windows, doors, decks and general carpentry.
Why it ranks here. Trading since 1955, 71 years, and still family run. The carpentry capability matters on New England housing where ice damming rots fascia and soffit alongside the roof deck, and a roofer who cannot do carpentry has to stop at the drip edge.
Best fit for: Ice dam damage extending into fascia, soffit or trim.

What they actually do. Roofing, siding, gutters, downspouts, windows and doors across northern Middlesex County.
Why it ranks here. Trading since 1956, seventy years, and serving a tightly defined set of eight towns rather than the whole metro. That geographic focus is a genuine positive: a firm that has roofed the same towns for seventy years cannot afford a bad job.
Best fit for: Middletown, Cromwell, Portland, Durham and Haddam homeowners.
What we would want clarified. At 142 registry reviews the evidence base is the thinnest in this top five, reflecting the deliberately narrow service area. We publish this because a ranking that only prints the flattering findings is an advertisement, not an assessment.

The 256 wind reports that shape a Hartford roof
Aggregate hail counts tell you very little about a specific roof. These are the individual events: every severe-weather report logged by the National Weather Service across the 2 counties of the Hartford-West Hartford-East Hartford, CT statistical area over ten years, with the dates, the stone sizes and the towns they landed on. Over that decade the metro logged 49 hail reports, 256 severe thunderstorm and high wind reports and 4 tornadoes. Reported property damage from hail, severe wind and tornado over that decade totalled $6.8 million; flood and winter-storm losses are counted separately and are not included.
The biggest hail to fall on Hartford in a decade
| Date | Stone size | Reported near | County |
|---|---|---|---|
| 15 May 2018 | 2.5 in | Granby | Hartford |
| 22 June 2024 | 1.75 in | East Hampton | Middlesex |
| 24 August 2020 | 1.75 in | Fogelmarks Corners | Middlesex |
| 22 June 2024 | 1.5 in | East Glastonburg | Hartford |
| 22 August 2020 | 1.25 in | Millington | Middlesex |
| 26 April 2019 | 1.25 in | Hydeville | Tolland |
The largest stone on record for this metro fell on 15 May 2018 near Granby, 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 Hartford on 13 November 2021. Asphalt shingles begin lifting at roughly 67 mph when they are correctly nailed, and considerably below that when they are not.
Tornadoes. 4 tornadoes touched down in these counties over the decade, the strongest rated EF1 near Merrow on 4 September 2019.
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 13 November 2021 event near Hartford, reproduced verbatim:
In Windsor Locks at 404 PM EST. the ASOS at Bradley International Airport (KBDL) recorded a gust to 47 knots. However, the Bradley Weather Contract Observer Supervisor estimated that a gust to 70 knots occurred within one-half mile of the ASOS. A small brick wall just outside of the Signature building got completely blown down and flattened. There was also some structural damage to the front of the building. A small airplane that was parked on the ramp got blown and moved onto the grass. The top part of their backup rain gauge, the piece which funnels the precipitation into the collection tube, got torn off of the metal can and it blew completely away. The wind also had picked up something…
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 (88), June (73), August (61). The worst years on record were 2024 (52), 2021 (51), 2016 (42). If you are scheduling non-urgent work in Hartford, 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 Hartford. Weight your decision toward wind rating, ventilation and flashing detail rather than paying extra for impact-rated shingles.
Before you sign anything in Hartford
Licensing is required in CT. Connecticut requires registration as a Home Improvement Contractor with the Department of Consumer Protection for any permanent change to residential property where the contract price exceeds $200. Roofing falls squarely within that definition.
Registration requires a minimum of $20,000 general liability insurance, with the insurer and policy number declared on the application. Contractors performing roofing on commercial buildings must instead register with the DCP as a major contractor, which is a materially different and higher credential.
Check here: Connecticut DCP eLicense lookup. The $200 threshold means essentially every roofing job in Connecticut requires a registered contractor. There is no meaningful unregistered exemption for residential work.
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 Hartford actually has
10 certified roofing contractors serve the principal cities of the Hartford-West Hartford-East Hartford, CT statistical area, of which 8 hold the top President’s Club tier. The pool carries 3,289 customer reviews between them at a mean rating of 4.79.

How these Hartford rankings were produced
Every contractor in the Hartford-West Hartford-East Hartford, CT 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 10 certified contractors, of whom 8 hold President’s Club standing and 2 Master Elite, against a metro mean rating of 4.79. The top five were then researched individually against Better Business Bureau records, state licence registers and manufacturer directories. Anything unflattering that research surfaced appears above alongside the rest, and no company bought its position.
The full method, the weightings, what the GAF certification tiers actually mean, who is eligible to be ranked and what we do not claim are all set out on our roofer ranking methodology page.

It holds President’s Club certification with a 4.9 rating across 318 reviews. Highest-scoring is not the same as best fit for your specific job, and the four companies behind it score within 4.4 points.
How many certified roofing contractors serve Hartford?
10 contractors on the GAF certification registry serve the principal cities of the Hartford-West Hartford-East Hartford, CT statistical area as of September 2026, of which 8 hold President’s Club status.
How much damaging hail does Hartford get?
The Hartford-West Hartford-East Hartford, CT statistical area recorded 31 hail reports of 1 inch or larger and 1 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 Hartford in the last ten years?
The largest hailstone logged by the National Weather Service in the Hartford-West Hartford-East Hartford, CT statistical area between 2016 and 2025 measured 2.5 inches, reported near Granby on 15 May 2018. 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 49 hail reports. Reported property damage from hail, severe wind and tornado over that decade totalled $6.8 million; flood and winter-storm losses are counted separately and are not included.
When is the worst time of year for roof damage in Hartford?
Severe-weather reports in the Hartford-West Hartford-East Hartford, CT statistical area cluster in July, June, August, on the NOAA record for 2016 to 2025. Booking non-urgent roof work outside those months usually means shorter lead times, because local crews are not simultaneously triaging storm callouts.
Do roofers need a licence in CT?
Connecticut requires registration as a Home Improvement Contractor with the Department of Consumer Protection for any permanent change to residential property where the contract price exceeds $200. Roofing falls squarely within that definition. Registration requires a minimum of $20,000 general liability insurance, with the insurer and policy number declared on the application. Contractors performing roofing on commercial buildings must instead register with the DCP as a major contractor, which is a materially different and higher credential.
What should I check before hiring a roofer in Hartford?
The $200 threshold means essentially every roofing job in Connecticut requires a registered contractor. There is no meaningful unregistered exemption for residential work.
Is Hartford a hard market to find a good roofer in?
Hartford recorded zero damaging hail in the past decade. The roofing problem here is New England winter: ice damming, snow load and freeze-thaw at the eaves. Connecticut requires Home Improvement Contractor registration with the Department of Consumer Protection for any residential work above $200, so essentially every roofing job here requires a registered contractor. Commercial roofing requires a separate and higher major contractor registration. Notably, this metro has the deepest bench of genuinely old family firms in the programme, with two trading since the mid-1950s.
Is wind or hail the bigger risk to a roof in Hartford?
Wind, by a wide margin. The Hartford-West Hartford-East Hartford, CT statistical area logged 256 severe thunderstorm and high wind reports against 31 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.
