Older pitched roofs
Mid-century houses on both sides of the line call for roof repair at flashings, valleys and chimneys, and roof replacement when the shingles have run their course.
Roofers in Falls Church, VA
Falls Church is two permit jurisdictions under one name. Inside the independent City, the Department of Code Administration decides what a roof job needs. Seven Corners, Bailey's Crossroads, Idylwood, West Falls Church, Lake Barcroft and Pimmit Hills carry a Falls Church mailing address but answer to Fairfax County. We sort out which side of the line your house is on first, then talk through the roof.

City or county
Is a Falls Church mailing address inside the City or in Fairfax County?
The City's own address page says that not all Falls Church mailing addresses are inside the City limits. Its rules of thumb: most residential addresses in the City have three digits, most addresses numbered 1400 and over are outside it, and addresses on Leesburg Pike, Route 7, Arlington Boulevard, Route 50, Lee Highway or Route 29 are likely not in the City.
ZIP codes help only a little. The City's main ZIP is 22046, with a few properties in 22042, 22044 and 22205, so a ZIP alone does not settle it.
What we do here
Which roof work fits a Falls Church house, townhouse or condominium?
The housing mix decides the work, and it splits along the City line.
Townhouse and condominium roofs
Attached buildings bring shared roof sections, association approvals and, in the county, a fire-rated decking question.
Low-slope roofs
Rear additions, porch tops and multi-unit buildings use membranes, covered in the TPO section below and on our flat roof page. See all materials.
Permits
Which office do you ask about a roof permit in Falls Church?
Confirm your exact scope with the office before work is scheduled. The table shows what each office's pages say today.
| What you plan | City of Falls Church addresses | Fairfax County addresses with a Falls Church mailing city |
|---|---|---|
| Who to ask | Department of Code Administration, permits line 703-248-5080, zoning line 703-248-5040 | Fairfax County Land Development Services, 703-222-0801 |
| Replacing the roof covering on a single-family house | The City says you can replace your roof without a permit as long as you are not replacing rafters or a major portion of the decking | The county lists replacement of roof shingles among work that needs no permit |
| Roof repairs or chimney repairs | The City's pages do not address these, so confirm with the office | The county lists roof repairs and chimney repairs as work that needs a permit |
| Replacing roof plywood or framing | The City says anything involving framing needs a permit and does not put a number on a "major portion" of decking, so ask the office | The county lists replacing less than 256 square feet (9 boards) of roof plywood as no permit, unless the decking must be fire rated, such as on townhomes |
| Townhouse or condominium roof | The City's pages are written for single-family dwellings, so ask the office | Fire-rated decking on townhomes is the county's one exception to the plywood allowance |
Office names moved recently. The City's Code Administration page says that effective July 1, 2026 its former Zoning and Building Safety divisions combined into one Department of Code Administration at City Hall, 300 Park Avenue.
The permits counter runs Monday to Friday, 8 a.m. to 5 p.m., and is closed to the public on the last Wednesday of the month.
For county addresses the Virginia building code also matters. The Virginia building code, section 13VAC5-63-80, exempts replacing roof covering on houses in most wind zones, but lets a building official require a permit in a locally designated historic district.
Historic overlay
Does the HARB historic overlay control a Falls Church re-roof?
The City's Historic Architectural Review Board reviews applications to demolish or move protected structures in the historic district, and that district is a zoning overlay covering the entire City. The City defines historic structures as those built as residences during or before 1910, plus any other structure the ordinance names.
For alterations of historic structures the page says the board makes recommendations only. It does not mention roofing. Because the overlay is citywide, owners of very old houses should confirm with Code Administration. Outside the City, none of Fairfax County's historic overlay districts carries the name of a Falls Church area.
Low-slope roofs
TPO roofing in Falls Church
TPO is the white or light gray membrane on many low-slope roofs. Here is where it fits in this mix of housing.
Where TPO shows up
Low-slope roofs matter more here than in a houses-only suburb, because about 54 percent of City units sit in buildings with two or more units. Rear additions, porch tops and condominium roofs are where a membrane is usually considered.
What the membrane is
TPO is a single-ply thermoplastic sheet. Seams are heat-welded with hot air, the surface is usually white or light so it reflects sun, and flashings at walls, drains and vents are done with matching pieces.
What to check before choosing it
Look at the drainage first, because TPO should not sit in standing water. Ask whether the insulation under the old roof is wet, whether the old surface can stay under a new one, and who maintains the roof on an attached building.
When something else fits better
EPDM is the black rubber alternative, and PVC suits roofs that take cooking exhaust or oils. Our flat roof page compares TPO, EPDM, PVC and modified bitumen side by side, and the TPO, EPDM and modified bitumen guide goes deeper.
Housing stock
What do roofs cover in the City, and what do they cover in West Falls Church and Lake Barcroft?
Census numbers describe homes, not roofs, so treat them as context. They come from the American Community Survey 2024 five-year estimates.
City: older than it looks
The City has 6,585 housing units with a median build year of 1971. Of those, 48.9 percent date from before 1970, and 52.5 percent of occupied homes are owner-occupied.
City: not a houses-only market
Detached houses are 36.5 percent of City units and attached townhouses 9.7 percent. Buildings with 50 or more units hold 37.8 percent, so condominium and apartment roofs are a real share of the work.
County side: mid-century houses
West Falls Church is 60.1 percent detached with a median build year of 1962, Lake Barcroft 61.7 percent and 1961, and Pimmit Hills 74.2 percent and 1965. Seven Corners is the opposite: 13.6 percent detached, with 45.0 percent of units in buildings of 50 or more.
Two neighborhood histories explain why so many county houses are now at the stage of flashing and shingle questions. Lake Barcroft's association says homesites were first sold in the summer of 1950, across about 1,020 lots. Pimmit Hills says ground was broken in May 1950 for 1,642 homes, most on small three-bedroom plans.
Weather and trees
What did the September 2026 storm do around West Falls Church?
FFXnow reported that the overnight thunderstorm of September 3 and 4, 2026 brought gusts topping 60 mph, reaching 69 mph around Tysons, and that more than 16,000 Dominion customers in Fairfax County lost power. Its list of downed-tree closures included Annandale Road at Graham Road in West Falls Church. The report describes outages and fallen trees, not roof damage in Falls Church.
Metro stations are not the City line. East Falls Church station is in Arlington County and West Falls Church station is in Fairfax County.

FAQ
Questions Falls Church owners ask about roofs and offices
My bill says Falls Church. Does the City of Falls Church handle my roof permit?
Only if the parcel is inside the 2.05 square mile City. Many Falls Church mailing addresses are in Fairfax County, and those go to Land Development Services. Give us your street address and we will point you to the right office.
What does "a major portion of the decking" mean in the City's roof rule?
The City's page gives no square-foot figure for it. If your plan includes replacing roof boards, call Code Administration at 703-248-5080 with the scope and ask how it applies to your house.
Why is the permit counter closed on some Wednesdays?
The City's page says the counter is closed to the public on the last Wednesday of each month.
Does the Historic Architectural Review Board approve a new roof on a pre-1910 house?
The board's page says it makes recommendations only for alterations of historic structures, and that mandatory review applies to demolition or moving. Roofing is not mentioned, so confirm with Code Administration, especially because the overlay covers the whole City.
I live in Lake Barcroft or Pimmit Hills. Which rules apply to my re-roof?
Those are Fairfax County communities, so the county's guidance applies, not the City's. The county lists shingle replacement as no-permit work and roof repairs as permit work, with fire-rated decking the exception on townhomes.
Is the East Falls Church Metro area inside the City of Falls Church?
No. The station is in Arlington County, so a house near it follows Arlington's rules, not the City's. See Arlington.
Which City office should I call now that Zoning and Building Safety have merged?
The Department of Code Administration. The permits line is 703-248-5080 and the zoning line is 703-248-5040, both listed on the City's own page.
Can a TPO membrane go on a condominium roof in Falls Church?
Often it can, if the drainage works, the insulation is dry and the association agrees to the product. Many buildings here are multi-unit, so ask who owns the roof before choosing a system.
