Short answer: As of September 2026, the five highest-scoring roofing contractors in the Washington-Arlington-Alexandria, DC-VA-MD-WV metro on The Roofing Brief Contractor Score are American Home Contractors, LLC (91.4), Keystone Building and Restoration (89.3), Augustine Roofing (86.5), Roof-ER (85.8), Panda Exteriors LLC (85.7). 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 27 certified roofing contractors serving the Washington metro on a published, reproducible formula, then researched each of the top five individually to confirm its record. Three governments license roofers in the Washington metro, and none of their licences crosses a border. The District requires a Home Improvement Contractor licence, Maryland requires a licence from its Home Improvement Commission, and Virginia requires a state contractor licence for any job over $1,000. All five of the highest-scoring certified contractors work from the Maryland and Virginia suburbs, 13 to 22 miles from the centre, and every one of them is President’s Club, including Fulton’s American Home Contractors with 4,013 registry reviews, the second-deepest record of any contractor in this programme. The weather is summer wind: 3,188 severe wind reports in ten years, and on 12 July 2022 thunderstorm winds near 80 mph felled hundreds of trees in College Park and Berwyn Heights, splitting a two-storey house near the University of Maryland in half.
What a Washington roof is up against
Match the licence to the jurisdiction of the house. In the District, the Department of Licensing and Consumer Protection issues the Home Improvement Contractor licence required for residential repair and alteration work, roofing included. In Maryland, the Home Improvement Commission licenses contractors and runs a Guaranty Fund that compensates homeowners for poor workmanship or failure to perform, up to the amount paid to a maximum of $30,000, but only for work by a licensed contractor. In Virginia, the Department of Professional and Occupational Regulation licenses contractors for any project over $1,000, in Class C, B and A tiers by project value. Keystone Building and Restoration shows Maryland licence 119186 on its BBB record; ask every contractor for the number that applies to your address.
The ten-year NOAA record holds 3,188 severe thunderstorm and high wind reports, the most of any metro in this batch, alongside 350 hail reports and 40 tornadoes, with $118.8 million in reported property damage. July is the peak month. Hail can be large, 3 inches at Bluemont in Loudoun County on 16 June 2016 and 2.75 inches at Rockville on 2 May 2016, but the recurring roof damage comes from trees. On 12 July 2022 falling trees also landed on dozens of houses around Olney, and Greenbelt Park stayed closed for weeks. Trimming limbs that overhang the roof is cheap insurance in this region.
Washington has a vetting resource few metros share: Consumers’ Checkbook, the nonprofit consumer magazine that rates local service companies from surveys of its members. Augustine Roofing, third below, has 92 reviews there. It is worth checking any contractor you shortlist, because Checkbook’s ratings come from a membership panel rather than from reviews the contractor solicits, which is the main weakness of both manufacturer registries and search-engine reviews.
Two of the five, American Home Contractors and Panda Exteriors, also score into the top five for the Baltimore metro. That is not double counting: Fulton and Laurel sit on the corridor between the two cities, and both companies work all of it. For homeowners in Montgomery and Prince George’s counties it puts two of the region’s deepest review records close by. In Arlington, Alexandria and Fairfax, the Virginia-based Augustine Roofing and Roof-ER are nearer, and a Maryland firm needs its own Virginia licence to work there.

What 3.0 inch hail does to a Washington 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 23 counties of the Washington-Arlington-Alexandria, DC-VA-MD-WV statistical area over ten years, with the dates, the stone sizes and the towns they landed on. Over that decade the metro logged 350 hail reports, 3,188 severe thunderstorm and high wind reports and 40 tornadoes. Reported property damage from hail, severe wind and tornado over that decade totalled $118.8 million; flood and winter-storm losses are counted separately and are not included.
The biggest hail to fall on Washington in a decade
| Date | Stone size | Reported near | County |
|---|---|---|---|
| 16 June 2016 | 3.0 in | Bluemont | Loudoun |
| 2 May 2016 | 2.75 in | Rockville | Montgomery |
| 2 May 2016 | 2.75 in | St Charles | Charles |
| 2 May 2016 | 2.5 in | Rockville | Montgomery |
| 14 May 2018 | 2.5 in | Charles Town | Jefferson |
| 15 May 2018 | 2.5 in | Frederick | Frederick |
The largest stone on record for this metro fell on 16 June 2016 near Bluemont, measured at 3.0 inches. That is baseball sized, comfortably past the point where a roof is written off rather than repaired.
Wind. The strongest thunderstorm gust logged in the metro was 80 knots, about 92 mph, near Branchville on 12 July 2022. Asphalt shingles begin lifting at roughly 67 mph when they are correctly nailed, and considerably below that when they are not.
Tornadoes. 40 tornadoes touched down in these counties over the decade, the strongest rated EF1 near La Plata on 25 February 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 12 July 2022 event near Branchville, reproduced verbatim:
Hundreds of trees snapped and uprooted in College Park and Berwyn Heights with dozens falling onto homes and crushing vehicles, especially near the University of Maryland where large falling trees caused a two story house to split in half. Greenbelt Park remained closed for several weeks due to fallen trees.
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 (1007), August (698), June (677). The worst years on record were 2019 (568), 2021 (462), 2017 (411). If you are scheduling non-urgent work in Washington, 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 322 damaging-hail reports in ten years, impact resistance in Washington 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.
How to tell a Washington roofer’s claims from their record
Licensing is required in DC. Any contractor performing residential remodelling, alteration or repair in the District of Columbia must hold a Basic Business License with the Home Improvement Contractor endorsement from the Department of Licensing and Consumer Protection, formerly DCRA. Roofing falls under that endorsement.
The HIC endorsement requires a $25,000 surety bond, a Clean Hands certificate from the DC Office of Tax and Revenue, a Certificate of Occupancy or Home Occupation Permit, and passing scores on a DC examination covering the DC Construction Codes plus business and law.
Check here: DC DLCP Home Improvement Contractor licensing. This metro spans four jurisdictions. Maryland work requires a Maryland Home Improvement Commission licence, and Virginia work requires a DPOR licence in the 2705 series. A contractor licensed in one is not thereby licensed in the others.
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 Washington actually has
27 certified roofing contractors serve the principal cities of the Washington-Arlington-Alexandria, DC-VA-MD-WV statistical area, of which 17 hold the top President’s Club tier. The pool carries 17,226 customer reviews between them at a mean rating of 4.822. The statistical area had a 2024 population of 6,436,489, a change of 2.51% against the 2020 census base, per the U.S. Census Bureau Vintage 2024 estimates.
How these Washington rankings were produced
Every contractor in the Washington-Arlington-Alexandria, DC-VA-MD-WV 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 27 certified contractors, of whom 17 hold President’s Club standing and 10 Master Elite, against a metro mean rating of 4.822. 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.

Common questions about roofers in Washington
Who is the best roofer in Washington, DC?
American Home Contractors, LLC of Fulton, MD scores highest in the Washington metro on The Roofing Brief Contractor Score, at 91.4 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 5.7 points.
How many certified roofing contractors serve Washington?
27 contractors on the GAF certification registry serve the principal cities of the Washington-Arlington-Alexandria, DC-VA-MD-WV statistical area as of September 2026, of which 17 hold President’s Club status.
How much damaging hail does Washington get?
The Washington-Arlington-Alexandria, DC-VA-MD-WV statistical area recorded 322 hail reports of 1 inch or larger and 13 of 2 inches or larger between 2016 and 2025 in the NOAA Storm Events Database. The largest hailstone reported measured 3.0 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 Washington in the last ten years?
The largest hailstone logged by the National Weather Service in the Washington-Arlington-Alexandria, DC-VA-MD-WV statistical area between 2016 and 2025 measured 3.0 inches, reported near Bluemont on 16 June 2016. That is baseball sized, comfortably past the point where a roof is written off rather than repaired. Across the decade the metro recorded 350 hail reports. Reported property damage from hail, severe wind and tornado over that decade totalled $118.8 million; flood and winter-storm losses are counted separately and are not included.
When is the worst time of year for roof damage in Washington?
Severe-weather reports in the Washington-Arlington-Alexandria, DC-VA-MD-WV statistical area cluster in July, August, June, 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 DC?
Any contractor performing residential remodelling, alteration or repair in the District of Columbia must hold a Basic Business License with the Home Improvement Contractor endorsement from the Department of Licensing and Consumer Protection, formerly DCRA. Roofing falls under that endorsement. The HIC endorsement requires a $25,000 surety bond, a Clean Hands certificate from the DC Office of Tax and Revenue, a Certificate of Occupancy or Home Occupation Permit, and passing scores on a DC examination covering the DC Construction Codes plus business and law.
What should I check before hiring a roofer in Washington?
This metro spans four jurisdictions. Maryland work requires a Maryland Home Improvement Commission licence, and Virginia work requires a DPOR licence in the 2705 series. A contractor licensed in one is not thereby licensed in the others.
Is Washington a hard market to find a good roofer in?
Three governments license roofers in the Washington metro, and none of their licences crosses a border. The District requires a Home Improvement Contractor licence, Maryland requires a licence from its Home Improvement Commission, and Virginia requires a state contractor licence for any job over $1,000. All five of the highest-scoring certified contractors work from the Maryland and Virginia suburbs, 13 to 22 miles from the centre, and every one of them is President’s Club, including Fulton’s American Home Contractors with 4,013 registry reviews, the second-deepest record of any contractor in this programme. The weather is summer wind: 3,188 severe wind reports in ten years, and on 12 July 2022 thunderstorm winds near 80 mph felled hundreds of trees in College Park and Berwyn Heights, splitting a two-storey house near the University of Maryland in half.
Is wind or hail the bigger risk to a roof in Washington?
Wind, by a wide margin. The Washington-Arlington-Alexandria, DC-VA-MD-WV statistical area logged 3,188 severe thunderstorm and high wind reports against 322 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.
