Best Roofers in Trenton, NJ: 5 Certified Contractors, Scored and Verified

The 5 best roofers in Trenton, NJ, ranked on a published formula and verified individually against BBB, licence and manufacturer records. No paid placement.

Best Roofers in Trenton, NJ: 5 Certified Contractors, Scored and Verified

Short answer: As of September 2026, the five highest-scoring roofing contractors in the Trenton-Princeton, NJ metro on The Roofing Brief Contractor Score are Trenton Roofing & Siding Inc. (95.7), Dream Home Roofing (91.0), Elegant Exteriors LLC (90.0), J & S Family Roofing LLC (88.9), Top Line Roofing LLC (85.7). 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 11 certified roofing contractors serving the Trenton metro on a published, reproducible formula, then researched each of the top five individually to confirm its record. Trenton has the oldest housing stock of any metro on this site: a median year built of 1953 in the city, against 1969 for Mercer County, with 13,155 of the city’s 34,513 housing units, 38.1 percent, built in 1939 or earlier. New Jersey then does something surprising with those roofs. Under the Uniform Construction Code, replacing the roof covering on a detached one or two family dwelling is ordinary maintenance requiring no permit, no inspection and no notice to the enforcing agency. The word doing the work there is detached, because a great deal of Trenton is rowhouses, which the exemption does not reach. So whether your reroof is inspected at all depends on whether your house touches your neighbour’s, and that is the first thing to establish here.

The conditions a Trenton roof has to be specified for

Mercer County is a quiet metro by severe-weather standards. Across 2016 to 2025 it logged 23 hail reports, only 13 of them an inch or larger, alongside 110 severe thunderstorm and high wind reports and 8 tornado events. July leads with 39 reports, then June with 28 and April with 21. What actually ages a Trenton roof is not a storm season but time and snow load. The heaviest storm on record at Trenton Mercer Airport is the blizzard of 22 and 23 January 2016, which dropped 18.5 inches including a record 16.7 inch calendar day. New Jersey withdrew its published county ground snow load values in Bulletin 19-1 and Mercer is not on the retained case-study list, so we cannot quote a design figure in pounds per square foot and will not invent one. What we can say is that the failure mode here is accumulated age, flashing and valley detail rather than impact.

The permit position is the single most consequential local rule, and it is more nuanced than most homeowners are told. N.J.A.C. 5:23-2.7 lists the repair or replacement of existing roof covering on detached one and two family dwellings as ordinary maintenance, for which no permit, inspection or notice to the enforcing agency is required. Two limits matter enormously in this city. First, detached means detached: Trenton’s rowhouses and attached dwellings fall outside the exemption entirely. Second, N.J.A.C. 5:23-2.7(b) pulls back any work affecting structural or fire safety, which is where decking replacement lands, so the moment a tear-off reveals rotten sheathing the job may stop being ordinary maintenance. On a house built before 1939, and 38 percent of Trenton’s stock was, bad decking is a live possibility rather than a remote one. Where a permit is required it is municipal rather than county, and the fee is a unit rate per $1,000 of estimated cost under N.J.A.C. 5:23-4.17 plus a state surcharge of $1.90 per $1,000 under 5:23-4.19. Trenton publishes no fee schedule on its building pages, so ask the Division of Inspections for the current unit rate rather than accepting a contractor’s estimate of it.

New Jersey’s contractor credential is a registration, not a competency licence, and it is worth knowing exactly what it does and does not test. Home Improvement Contractors must register with the Division of Consumer Affairs and display a number beginning 13VH on every contract, advertisement and commercial vehicle. The Division’s own registration instructions enumerate the requirements in full: a $110 fee, formation documents, a federal employer identification number, commercial general liability insurance of at least $500,000 per occurrence, workers’ compensation cover unless exempt, and additional security at $10,000, $25,000 or $50,000. Nowhere in that list is an examination, a competency test or an experience requirement. The 2024 changes are real, added by P.L. 2023 c.237 signed on 8 January 2024, which brought in the workers’ compensation and security requirements with immediate effect, but the board-issued licence that will finally carry an examination only takes effect six months after the new board adopts rules. Until then, the registration proves a contractor is insured and on the register, which is why every entry below states whether we found the registration and what name it is held in.

One code point clears up a common misconception. New Jersey amends section R905.1.2 of the residential code so that the ice barrier requirement is triggered where the average daily temperature in January is 25 degrees Fahrenheit or lower, and Department of Community Affairs Bulletin 07-3 states plainly that for the State of New Jersey that area is Sussex County. Mercer County is not in it, and NOAA’s 1991 to 2020 January normal at Trenton Mercer Airport is 32.0 degrees, so an ice barrier is not a code requirement on a Trenton roof. That does not make it a bad idea on a shallow-pitch older roof with a history of ice at the eaves, but a contractor presenting it as code-mandated in Mercer County is mistaken. New Jersey adopts the 2024 International Residential Code as its one and two family dwelling subcode, so the edition being enforced is current.

1. Trenton Roofing & Siding Inc. — TRB Score 95.7

Trenton Roofing & Siding Inc. is based in Trenton, NJ, in business since 1982, led by Joseph F. Gankiewicz, President; Alex Valentino listed by the BBB as Vice President, BBB accredited since 1 May 2001, A+ rating; BBB records a 1982 founding, and holds President’s Club standing on the GAF certification registry.

Total 95.7 100

Independently corroborated:

What they actually do. Asphalt shingle replacement, roof repairs and inspections, commercial roof sealing, siding, gutters, windows and shutters, skylights and chimney chase caps.

Why it ranks here. The clear leader and one of the strongest single entries in this programme: 43 years in the city, BBB accredited since 2001 at A+, an Active New Jersey registration held in the owner’s own name at the Trenton address it trades from, and 4.9 across 1,535 registry reviews, which is the deepest customer record of any metro-local roofer we have ranked. It is based in Chambersburg, in Trenton proper, and its service-area page lists more than 150 New Jersey municipalities and over 200 Pennsylvania towns.

Best fit for: Almost any roof in Mercer County, and the obvious first call on an older attached or rowhouse property where local experience counts.

What we would want clarified. One practical warning. The domain trentonroofingandsiding.com is not this company and currently serves unrelated online gambling content; the correct address is trentonroofing.com. We could not independently verify the 1,535 review count, because Google, Yelp, Angi and the GAF directory all refuse automated access, and the BBB itself holds only four reviews; the figure is plausible for a 1982 business but the reviews sit on a Google Business Profile we could not read. Its self-published Pennsylvania registration PA043363 is also unverified, as the Pennsylvania register refused every request. 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 (609) 393-6780, 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. Dream Home Roofing — TRB Score 91.0

Dream Home Roofing is based in Hamilton, NJ, led by Gianni Tonti, Owner; Kimberly Tonti, named on the company’s site as Founder and CFO, BBB accredited since 26 May 2020, A+ rating; BBB gives a business start date of 24 September 2019, and holds President’s Club standing on the GAF certification registry.

Certifications held: President’s Club (GAF), Owens Corning Preferred Contractor, OSHA certified (company statement). Certification by more than one manufacturer is uncommon and requires meeting each programme’s separate standards for insurance, training and track record.

Total 91.0 100

Independently corroborated:

What they actually do. Roof replacement, repair and inspections, asphalt shingle and commercial roofing, CertainTeed and James Hardie siding, gutters, solar panel installation and storm damage restoration.

Why it ranks here. The strongest in-county alternative to the leader, and on paper the best-credentialed firm on this page: President’s Club with GAF plus an Owens Corning Preferred Contractor credential, 4.9 across 445 reviews, BBB accredited at A+ since 2020, and based in Hamilton Township about four miles from downtown Trenton. Its New Jersey registration is held by Dream Home Contracting Group Inc, whose registered owner and street address in the state record match the roofing business exactly, so the entity chain is clean.

Best fit for: A second quote alongside the leader, and the better choice if you want a second manufacturer’s certification or solar on the same job.

What we would want clarified. The registration and the trading name differ, so check it under Dream Home Contracting Group Inc rather than Dream Home Roofing. It publishes no founding year, and its records give three different start dates: a BBB business start of September 2019, a state incorporation of June 2021 and a registration issued September 2021, while the site calls it a second-generation business. Its stated service area is broad, covering surrounding New Jersey counties plus New York, Pennsylvania and Connecticut. 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 (609) 533-2432, 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.

3. Elegant Exteriors LLC — TRB Score 90.0

Elegant Exteriors LLC is based in New Egypt, NJ, in business since 2014, led by Matthew George Stillwell and Ryan Frederick Stillwell, BBB accredited since 26 September 2017, A+ rating; no complaints closed in the past three years, and holds President’s Club standing on the GAF certification registry.

Independently corroborated:

What they actually do. Roofing, siding, windows and gutters.

Why it ranks here. A clean 5.0 across 265 reviews, BBB accredited at A+ since 2017 with no complaints closed in three years, and an Active New Jersey registration since 2014 in both owners’ names. Every public record lines up: the state formation date, the BBB start date and the registration all agree, which is rarer than it should be.

Best fit for: Homeowners in the eastern half of the metro, or anyone willing to ask a well-rated firm to travel.

What we would want clarified. Confirm it will actually come to you before anything else. It is based in New Egypt, in Ocean County, about 20 miles east of Trenton, and the only service area we could source, from its BBB profile, lists Ocean, Monmouth and Burlington counties, with Mercer County not among them. It has no website at all, and it is registered with an alternate name, RMS Construction, so check the registration under Elegant Exteriors LLC. 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.

Verify the certification yourself on the GAF registry listing. The number carried on that listing is (908) 692-1728, 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.

4. J & S Family Roofing LLC — TRB Score 88.9

Independently corroborated:

What they actually do. Roofing.

Why it ranks here. A clean 5.0 across 248 reviews and properly papered for New Jersey work despite being a Pennsylvania business: it is registered twice over here, as a foreign LLC with the Division of Revenue since 1 June 2018 and as a Home Improvement Contractor with Consumer Affairs, registration Active to March 2027. Among the out-of-state firms in this pool it is the one whose right to work in New Jersey is clearest.

Best fit for: A competitive quote from across the Delaware, if it will travel to Mercer County.

What we would want clarified. You will have to ask, because it publishes nothing. It has no website at all, and no service-area statement naming Trenton or Mercer County could be found anywhere, so its coverage of this metro is unverified. It is based in the Horsham and Warminster area of Montgomery and Bucks counties, roughly 30 miles north-east of Trenton. Its BBB profile is not accredited and holds a single review, the two public records give different street addresses, and its registration shows a reinstatement rather than continuous standing. No Pennsylvania registration number could be verified. We publish this because a ranking that only prints the flattering findings is an advertisement, not an assessment.

5. Top Line Roofing LLC — TRB Score 85.7

Top Line Roofing LLC is based in Cinnaminson, NJ, in business since 2023, led by Christian D. Lalvay Lluisupa, Owner, BBB accredited, A+ rating; no customer reviews currently listed, and holds President’s Club standing on the GAF certification registry.

Independently corroborated:

What they actually do. Residential roof installation, replacement and restoration, reroofing, storm damage repair and ice shield installation.

Why it ranks here. A New Jersey company with an Active registration in the owner’s own name, BBB accredited at A+, holding President’s Club certification and 4.9 across 271 reviews. It is the only firm on this page that lists ice shield installation as a distinct service, which is a reasonable optional upgrade on an older shallow-pitch Trenton roof even though, as set out above, it is not code-required in Mercer County.

Best fit for: Homeowners in the southern half of the metro who want a New Jersey registered firm, on a competitive quote.

What we would want clarified. It is the youngest business on this page by a wide margin, formed on 16 May 2023, so its 271 registry reviews have accumulated in about two years and the BBB currently lists no customer reviews at all to cross-check them against. The BBB also gives an accreditation date of February 2022, which precedes the company’s own formation date, and we used the state record. It is based in Cinnaminson, in Burlington County about 25 miles south-west of Trenton, and no published service area could be found, so confirm it covers Mercer County. 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 (888) 660-6049, 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.

The 110 wind reports that shape a Trenton 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 Trenton-Princeton, NJ statistical area over ten years, with the dates, the stone sizes and the towns they landed on. Over that decade the metro logged 23 hail reports, 110 severe thunderstorm and high wind reports and 8 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 Trenton in a decade

Date Stone size Reported near County
6 July 2020 1.5 in White Horse Mercer
6 July 2020 1.25 in Mercerville Mercer
29 May 2019 1.25 in Groveville Mercer
1 April 2023 1.0 in Mercerville Mercer
1 April 2023 1.0 in Ajax Park Mercer
6 July 2020 1.0 in White Horse Mercer

The largest stone on record for this metro fell on 6 July 2020 near White Horse, measured at 1.5 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 62 knots, about 71 mph, near Groveville on 1 April 2023. Asphalt shingles begin lifting at roughly 67 mph when they are correctly nailed, and considerably below that when they are not.

Tornadoes. 8 tornadoes touched down in these counties over the decade, the strongest rated EF2 near Titusville on 29 July 2021.

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 3 September 2020 event near Trenton, reproduced verbatim:

Downed trees, wires, and some minor roof damage were reported in a concentrated are in Hamilton Twp, especially near Redfern St. Time estimated from radar.

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 (39), June (28), April (21). The worst years on record were 2019 (35), 2020 (28), 2023 (26). If you are scheduling non-urgent work in Trenton, 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 Trenton. Weight your decision toward wind rating, ventilation and flashing detail rather than paying extra for impact-rated shingles.

What a Trenton homeowner should ask for in writing

Licensing is required in NJ. New Jersey has no general contractor licence. Anyone performing home improvement work including roofing must instead hold a Home Improvement Contractor registration with the New Jersey Division of Consumer Affairs, and must display that registration number, which begins 13VH, on every contract, advertisement and commercial vehicle.

Registration requires business information, a fee and a certificate of commercial general liability insurance of at least $500,000 per occurrence. It is a consumer-protection registration rather than a competency licence. The Division of Consumer Affairs says so itself in its guidance to homeowners: “Registration with the State does not constitute an endorsement of or approval for the home improvement contractor.” A contractor who is not registered also cannot be issued a municipal construction permit.

Check here: New Jersey licence verification. Check the 13VH number on the state verification site, and read the registration for what it is. Because the state describes it as neither an endorsement nor an approval, a manufacturer certification and a documented work record carry more weight in New Jersey than the registration on its own.

Four checks to run before you sign anything, in any state.

  1. Verify certification at the source. Use the GAF verification tool rather than trusting a badge image on a company website.
  2. 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.
  3. Confirm who pulls the permit. If a contractor asks you to pull it as the homeowner, that moves liability onto you. Decline.
  4. Get warranty terms in writing before any deposit, and check the manufacturer warranty being promised actually requires the certification tier the contractor holds.

Who else is certified in Trenton

11 certified roofing contractors serve the principal cities of the Trenton-Princeton, NJ statistical area, of which 11 hold the top President’s Club tier. The pool carries 3,686 customer reviews between them at a mean rating of 4.65.

How these Trenton rankings were produced

Every contractor in the Trenton-Princeton, NJ 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 11 certified contractors, of whom 11 hold President’s Club standing and 0 Master Elite, against a metro mean rating of 4.65. 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.

Set aside in Trenton. 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.

  • Munz Roofing and Siding, which scored 87.5: scored fifth and is, by some distance, the firm that markets Mercer County hardest: its service-area navigation lists Mercer among six New Jersey counties and it maintains dedicated pages for Mercer County and for Trenton itself. But we could not find a New Jersey Home Improvement Contractor registration in the name Munz Roofing, Munz Roofing and Siding, or Munz Roofing LLC. A search of the Division of Consumer Affairs register for Munz Roofing returns no results. New Jersey requires that registration before a contractor may solicit or perform home improvement work in the state, and requires the 13VH number to appear on advertisements and contracts, so a Pennsylvania-based firm advertising Trenton work is exactly the case the rule addresses. There is an active registration for a differently named entity, Munz Construction, Inc., 13VH03829900, owner Christopher Munz of Holland, Pennsylvania, and the Munz Roofing site refers to a Chris, but nothing we could find ties the two, and we are not going to assume it. Its BBB profile is also not accredited and currently shows as Not Rated with the profile under review. This is an absence of verification rather than a finding of wrongdoing, and it may well have a registration we could not surface: ask for the 13VH number and check it yourself before engaging them

Common questions about roofers in Trenton

Who is the best roofer in Trenton, NJ?

Trenton Roofing & Siding Inc. of Trenton, NJ scores highest in the Trenton metro on The Roofing Brief Contractor Score, at 95.7 out of 100 as of September 2026. It holds President’s Club certification with a 4.9 rating across 1,535 reviews. Highest-scoring is not the same as best fit for your specific job, and the four companies behind it score within 10.0 points.

How many certified roofing contractors serve Trenton?

11 contractors on the GAF certification registry serve the principal cities of the Trenton-Princeton, NJ statistical area as of September 2026, of which 11 hold President’s Club status.

How much damaging hail does Trenton get?

The Trenton-Princeton, NJ statistical area recorded 13 hail reports of 1 inch or larger and 0 of 2 inches or larger between 2016 and 2025 in the NOAA Storm Events Database. The largest hailstone reported measured 1.5 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 Trenton in the last ten years?

The largest hailstone logged by the National Weather Service in the Trenton-Princeton, NJ statistical area between 2016 and 2025 measured 1.5 inches, reported near White Horse on 6 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 23 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 Trenton?

Severe-weather reports in the Trenton-Princeton, NJ statistical area cluster in July, June, April, 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 NJ?

New Jersey has no general contractor licence. Anyone performing home improvement work including roofing must instead hold a Home Improvement Contractor registration with the New Jersey Division of Consumer Affairs, and must display that registration number, which begins 13VH, on every contract, advertisement and commercial vehicle. Registration requires business information, a fee and a certificate of commercial general liability insurance of at least $500,000 per occurrence. It is a consumer-protection registration rather than a competency licence. The Division of Consumer Affairs says so itself in its guidance to homeowners: “Registration with the State does not constitute an endorsement of or approval for the home improvement contractor.” A contractor who is not registered also cannot be issued a municipal construction permit.

What should I check before hiring a roofer in Trenton?

Check the 13VH number on the state verification site, and read the registration for what it is. Because the state describes it as neither an endorsement nor an approval, a manufacturer certification and a documented work record carry more weight in New Jersey than the registration on its own.

Is Trenton a hard market to find a good roofer in?

Trenton has the oldest housing stock of any metro on this site: a median year built of 1953 in the city, against 1969 for Mercer County, with 13,155 of the city’s 34,513 housing units, 38.1 percent, built in 1939 or earlier. New Jersey then does something surprising with those roofs. Under the Uniform Construction Code, replacing the roof covering on a detached one or two family dwelling is ordinary maintenance requiring no permit, no inspection and no notice to the enforcing agency. The word doing the work there is detached, because a great deal of Trenton is rowhouses, which the exemption does not reach. So whether your reroof is inspected at all depends on whether your house touches your neighbour’s, and that is the first thing to establish here.

Is wind or hail the bigger risk to a roof in Trenton?

Wind, by a wide margin. The Trenton-Princeton, NJ statistical area logged 110 severe thunderstorm and high wind reports against 13 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.

Why is Munz Roofing and Siding not on this list?

Scored fifth and is, by some distance, the firm that markets Mercer County hardest: its service-area navigation lists Mercer among six New Jersey counties and it maintains dedicated pages for Mercer County and for Trenton itself. But we could not find a New Jersey Home Improvement Contractor registration in the name Munz Roofing, Munz Roofing and Siding, or Munz Roofing LLC. A search of the Division of Consumer Affairs register for Munz Roofing returns no results. New Jersey requires that registration before a contractor may solicit or perform home improvement work in the state, and requires the 13VH number to appear on advertisements and contracts, so a Pennsylvania-based firm advertising Trenton work is exactly the case the rule addresses. There is an active registration for a differently named entity, Munz Construction, Inc., 13VH03829900, owner Christopher Munz of Holland, Pennsylvania, and the Munz Roofing site refers to a Chris, but nothing we could find ties the two, and we are not going to assume it. Its BBB profile is also not accredited and currently shows as Not Rated with the profile under review. This is an absence of verification rather than a finding of wrongdoing, and it may well have a registration we could not surface: ask for the 13VH number and check it yourself before engaging them.
