Roofing in Arlington, VA: permits, historic review and what your building type changes

Three questions that decide the path

Roofing in Arlington is not one process. The county sorts projects by building type before it sorts them by size of the job, and historic status can override both. Answer these three in order.

What the county says about re-roof permits

This is the county's table for houses and townhouses, from its residential building permit page (capture of December 30, 2025). It applies to replacing an existing roof, not to a first-time roof.

The state code is broader. Virginia's building code (13VAC5-63-80) exempts replacement of an unlimited amount of roof covering in groups R-3, R-4 and R-5 unless the area's nominal design wind speed is above 100 mph, and exempts replacement of 256 square feet or less of roof decking in the same groups unless that decking was required to be fire-retardant-treated or protected as a fire-rated wall termination. The county's table matches the 256 square foot figure, so use it as the working answer for an Arlington address and confirm anything unusual.

Two townhouse points the county prints

The county's permit page also says exhaust openings should not penetrate the roof within four feet of the party wall of a townhouse without a parapet. Its solar page adds that no part of a rooftop solar array may sit within four feet of a firewall that lacks a parapet extending at least 30 inches above the roof covering. These are reasons a townhouse roof needs more than a like-for-like quote.

Housing by ZIP code and what it means for a roof

Arlington has 121,970 homes, with a median year built of 1976. Only 24.8% are detached houses and 8.9% are attached homes such as townhouses. 61.5% are in buildings with five or more units, and just 41.3% are owner-occupied (American Community Survey 2024 five-year estimates, accessed October 17, 2026). That mix is why the process above matters: most Arlington roofs belong to a building, not a house.

Owners in larger buildings are a real share of the market: 11,999 owners, or 26.0% of all owner households, live in buildings of five or more units. For them a new roof is usually a decision made with other owners, funded from shared reserves and arranged through the association.

Historic districts: local versus National Register

Arlington County keeps two separate lists, and only one of them changes how a roof job is approved.

Local historic districts (review applies)

The county's A-Z list (capture of December 16, 2025) names 43 entries: 7 cemeteries, 2 commercial buildings, 3 community buildings, 3 forts, 3 garden-apartment complexes, 15 houses, 1 industrial structure, 2 institutional buildings, 1 natural element, 1 neighborhood, 1 place of worship and 4 schools. The one neighborhood is Maywood. The three garden-apartment complexes are Colonial Village, Buckingham Villages and Cambridge Courts.

Inside a local district, the county says a Certificate of Appropriateness is required for all proposed exterior alterations, new construction and demolition, with the exception of routine maintenance, repairs and replacements using the same materials, interior alterations and paint colors. The Historical Affairs and Landmark Review Board decides on either the district's own design guidelines or the U.S. Secretary of the Interior's Standards; the Zoning Ordinance uses the Standards where a district has no approved guidelines.

National Register of Historic Places (honorific)

The county describes the National Register as an honorific list. Its A-Z page lists 23 Arlington neighborhoods, among them Arlington Forest, Arlington Village, Cherrydale, Dominion Hills, Fairlington, Lyon Park and Lyon Village. Listing by itself does not bring the Certificate of Appropriateness process. A property can be on both lists, as Maywood and Buckingham Village are, and that is the case where the local rules apply.

Checking a roofer's Virginia licence

Virginia licenses contractors through the Board for Contractors. The Board's regulations define roofing contracting as the installation, repair, removal or improvement of materials common to the industry that form a watertight, weather-resistant surface for roofs and decks.

• A Class C license covers a single contract over one thousand dollars and under thirty thousand dollars, or work totaling under two hundred fifty thousand dollars in any twelve months.
• Class B starts at thirty thousand dollars on a single contract (or two hundred fifty thousand a year) and Class A at one hundred fifty thousand on a single contract (or one million a year).
• Under the Code of Virginia, bidding or contracting on another person's property without the proper class of license is a Class 1 misdemeanor, and the person receiving a bid is expected to ask for the license number first.

Ask any roofer for the license number, class and specialty, then check it on the Department of Professional and Occupational Regulation license lookup. This applies to every company you speak with, including us.

What to have your roofer confirm for your address

• Building type under the county test: detached or townhouse, and stories above ground level.
• Whether any decking will be replaced, how much, and whether the building was framed with fire-retardant-treated lumber.
• Whether the address or building name appears on the county's local historic district list.
• For a condo, co-op or apartment building: who approves the work and who pulls any permit.
• For a townhouse: where vents, skylights or solar will sit relative to the party wall.
• The contractor's Virginia license number, class and specialty.
