Short answer: As of September 2026, the five highest-scoring roofing contractors in the Baltimore-Columbia-Towson, MD metro on The Roofing Brief Contractor Score are American Home Contractors, LLC (91.2), Tar Heel Construction Group, LLC (91.2), Landmark Roofing (88.7), Wells Home Improvements, registered as Wells Home Improvement, LLC (85.6), Panda Exteriors LLC (84.7). Every one holds a manufacturer certification that can be verified independently, every rating below has been corroborated against at least one source outside the certification registry, and no company paid to appear here.
The Roofing Brief scored 12 certified roofing contractors serving the Baltimore metro on a published, reproducible formula, then researched each of the top five individually to confirm its record. Maryland requires a Home Improvement Commission licence for any residential roofing work, and the MHIC runs something most states do not: a Guaranty Fund that can reimburse a homeowner for losses caused by a licensed contractor. Hiring an unlicensed roofer in Maryland forfeits access to that fund entirely, which makes the licence check worth more here than in most states. Note also that two of the five below also rank in our Washington DC list, because the Baltimore and Washington metros adjoin and several certified contractors genuinely serve both.
The conditions a Baltimore roof has to be specified for
Maryland gives homeowners a genuinely useful backstop, and it only works if the contractor is licensed. The Home Improvement Commission licenses residential contractors and runs a Guaranty Fund that reimburses actual losses from unworkmanlike, incomplete or abandoned work, up to $30,000 per claimant or the amount you paid, whichever is less, with claims filed within three years of discovering the loss. A contractor who was unlicensed when the work was done puts you outside that scheme entirely. Check the MHIC number before you sign, not after a dispute starts.
Baltimore is a rowhouse city, and the rowhouse roof is a different job from a suburban replacement. The flat and low-slope roofs on the city’s attached houses are membrane work, typically modified bitumen or EPDM rather than shingles, and the details that leak are the ones at the edges: party-wall flashings shared with the neighbour, parapet copings, and scuppers or internal drains rather than gutters. Ask for recent rowhouse work specifically, ask how the party wall will be terminated, and ask whether the neighbouring roof has to be disturbed. Baltimore City requires a permit for a full replacement.
The weather here is wind-led to an unusual degree: 1,362 severe thunderstorm and high wind reports over the decade against 128 hail reports, with July the peak month and $91.8 million in reported property damage. On 7 August 2023 a single event brought down thousands of trees and dozens of utility poles around Westminster and Jarrettsville, with trees landing on houses. Tornadoes are infrequent but real, 34 in ten years, including an EF2 that crossed from Howard into Carroll County in November 2018 and a waterspout that came ashore near Stevensville in 2017.
Hail is the secondary risk and is mostly moderate: 112 of the 128 reports reached an inch, but only one made two inches, a tennis-ball stone south of Hampstead in May 2025. That balance argues for spending on wind performance rather than impact rating in this metro, so ask about nailing patterns, starter courses and drip edge, and on a low-slope roof about the membrane’s wind uplift rating. Two contractors in this ranking also appear on our Washington DC page, because Howard and Anne Arundel County firms genuinely work both metros.

What they actually do. Roofing, siding, windows, gutters, doors and solar across Maryland, DC and northern Virginia, with 40 years of trading.
Why it ranks here. One of the largest verified review corpora of any contractor in this programme, at 4,013 registry reviews, and a published MHIC licence number that unlocks Guaranty Fund protection. Dual manufacturer certification plus a Tesla solar credential is a combination almost no roofer holds.
Best fit for: Homeowners pairing a roof with solar, and anyone wanting maximum public evidence behind a rating.
What we would want clarified. Based in Fulton, between Baltimore and Washington, and it also ranks in our Washington DC list because it genuinely serves both metros. We publish this because a ranking that only prints the flattering findings is an advertisement, not an assessment.

What they actually do. Roof and siding replacement, roof repair, roof maintenance programmes and seamless gutters across Baltimore and Harford counties.
Why it ranks here. A perfect 5.0 across 802 registry reviews is the cleanest large-sample rating in the Baltimore pool. The maintenance programme offering is unusual: most roofers sell only replacement, so a firm selling scheduled maintenance has a reason to extend the life of the roof you already have.
Best fit for: Harford and north-east Baltimore County homeowners, and anyone wanting ongoing maintenance rather than one transaction.

Why it ranks here. The only company in the Baltimore top five genuinely centred on Anne Arundel County rather than the Baltimore or Washington cores, which matters for Severna Park, Annapolis and the Broadneck peninsula.
Best fit for: Anne Arundel County and Annapolis-area homeowners.
What we would want clarified. One documented account describes a leak appearing three years after replacement, with follow-up repairs taking several months and multiple unanswered calls.

Why it ranks here. 424 registry reviews at 4.9 with President’s Club certification, covering the Annapolis and Chesapeake side of the metro that the Baltimore city firms reach less often.
Best fit for: Annapolis, Anne Arundel and Eastern Shore homeowners.
What we would want clarified. A discrepancy worth knowing about. The company’s own website presents itself as BBB accredited with an A+ rating; the BBB’s own profile records it as not accredited. We make no finding on how that arose, but a claim a homeowner cannot verify at the source is the kind of thing to raise directly before signing. Twenty-three miles from the metro centre.

The 1,362 wind reports that shape a Baltimore 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 7 counties of the Baltimore-Columbia-Towson, MD statistical area over ten years, with the dates, the stone sizes and the towns they landed on. Over that decade the metro logged 128 hail reports, 1,362 severe thunderstorm and high wind reports and 34 tornadoes. Reported property damage from hail, severe wind and tornado over that decade totalled $91.8 million; flood and winter-storm losses are counted separately and are not included.
The biggest hail to fall on Baltimore in a decade
| Date | Stone size | Reported near | County |
|---|---|---|---|
| 16 May 2025 | 2.5 in | Fowblesburg | Baltimore |
| 1 August 2019 | 1.75 in | Arundel Gardens | Anne Arundel |
| 1 July 2020 | 1.75 in | Riva | Anne Arundel |
| 3 May 2025 | 1.75 in | Timonium | Baltimore |
| 3 May 2025 | 1.75 in | Benson | Harford |
| 12 May 2018 | 1.75 in | Oella | Baltimore |
The largest stone on record for this metro fell on 16 May 2025 near Fowblesburg, 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 78 knots, about 90 mph, near Cranberry Station on 7 August 2023. 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 Stevensville Bay Arp on 24 July 2017.
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 7 August 2023 event near Cranberry Station, reproduced verbatim:
Thousands of trees, branches and wires blew down near and north of Westminster. 30 utility poles snapped along MD-97/MD-140 Baltimore Boulevard near Gorsuch Road, with live wires trapping several people in their vehicles for a few hours; two people were injured. Dozens of roads in the area were blocked by storm debris for several days. Several homes suffered minor roof, shingle and siding damage. Several barns were destroyed.
A roof in this metro is built against events like that one, as recorded by the agency that recorded it rather than by a contractor selling the repair.
When it happens. Severe weather reports cluster in July (447), June (290), August (288). The worst years on record were 2019 (235), 2021 (199), 2020 (184). If you are scheduling non-urgent work in Baltimore, the months outside that window are when crews are least stretched and least likely to be triaging emergency callouts ahead of your job.

What to do with this. Baltimore sees enough damaging hail that a Class 4 impact-rated shingle is worth pricing, though not automatically worth buying. Get both quotes and weigh the premium against any insurance discount.
Three things to confirm before work starts in Baltimore
Licensing is required in MD. Maryland requires a Maryland Home Improvement Commission licence for any contractor performing roofing or other home improvement work on a residential property. Maryland issues no standalone roofing licence; the MHIC Home Improvement licence is the required credential statewide.
Applicants must document at least two years of home improvement, construction or related education experience, pass a licensing exam, carry at least $50,000 liability insurance at application and renewal, and demonstrate financial solvency through a full credit report and net worth review.
Check here: MHIC Home Improvement Public Query. The MHIC public query tool is free and confirms active status in real time by contractor name, licence number or location. Maryland also runs a Guaranty Fund that can reimburse homeowners for losses caused by a licensed contractor, so hiring unlicensed forfeits that protection.
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 Baltimore rankings were produced
Every contractor in the Baltimore-Columbia-Towson, MD 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 12 certified contractors, of whom 10 hold President’s Club standing and 2 Master Elite, against a metro mean rating of 4.767. The top five were then researched individually against Better Business Bureau records, state licence registers and manufacturer directories. Where that research turned up something awkward it is on the page, and no placement was paid for.
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.

Questions Baltimore homeowners ask
Who is the best roofer in Baltimore, MD?
American Home Contractors, LLC of Fulton, MD scores highest in the Baltimore metro on The Roofing Brief Contractor Score, at 91.2 out of 100 as of September 2026. It holds President’s Club certification with a 4.9 rating across 4,013 reviews. Highest-scoring is not the same as best fit for your specific job, and the four companies behind it score within 6.5 points.
How many certified roofing contractors serve Baltimore?
12 contractors on the GAF certification registry serve the principal cities of the Baltimore-Columbia-Towson, MD statistical area as of September 2026, of which 10 hold President’s Club status.
How much damaging hail does Baltimore get?
The Baltimore-Columbia-Towson, MD statistical area recorded 112 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 Baltimore in the last ten years?
The largest hailstone logged by the National Weather Service in the Baltimore-Columbia-Towson, MD statistical area between 2016 and 2025 measured 2.5 inches, reported near Fowblesburg on 16 May 2025. 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 128 hail reports. Reported property damage from hail, severe wind and tornado over that decade totalled $91.8 million; flood and winter-storm losses are counted separately and are not included.
When is the worst time of year for roof damage in Baltimore?
Severe-weather reports in the Baltimore-Columbia-Towson, MD statistical area cluster in July, June, August, on the NOAA record for 2016 to 2025. Outside those months local crews are not triaging storm damage, so lead times are shorter and scheduling is easier.
Do roofers need a licence in MD?
Maryland requires a Maryland Home Improvement Commission licence for any contractor performing roofing or other home improvement work on a residential property. Maryland issues no standalone roofing licence; the MHIC Home Improvement licence is the required credential statewide. Applicants must document at least two years of home improvement, construction or related education experience, pass a licensing exam, carry at least $50,000 liability insurance at application and renewal, and demonstrate financial solvency through a full credit report and net worth review.
What should I check before hiring a roofer in Baltimore?
The MHIC public query tool is free and confirms active status in real time by contractor name, licence number or location. Maryland also runs a Guaranty Fund that can reimburse homeowners for losses caused by a licensed contractor, so hiring unlicensed forfeits that protection.
Is Baltimore a hard market to find a good roofer in?
Maryland requires a Home Improvement Commission licence for any residential roofing work, and the MHIC runs something most states do not: a Guaranty Fund that can reimburse a homeowner for losses caused by a licensed contractor. Hiring an unlicensed roofer in Maryland forfeits access to that fund entirely, which makes the licence check worth more here than in most states. Note also that two of the five below also rank in our Washington DC list, because the Baltimore and Washington metros adjoin and several certified contractors genuinely serve both.
Is wind or hail the bigger risk to a roof in Baltimore?
Wind, by a wide margin. The Baltimore-Columbia-Towson, MD statistical area logged 1,362 severe thunderstorm and high wind reports against 112 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.
