Detached houses, 47.0 percent
Where a leak shows up at one chimney, vent or valley, roof repair traces it to that spot. Where wear runs across every slope, roof replacement comes into play.
No town hall, HOA-style body or county historic overlay approves roofs in Annandale, so the useful question is how old your building is. The median home here dates to 1968, 56.9 percent of homes were built before 1970, and 31.0 percent sit in buildings of five or more units. That mix, not a local rulebook, shapes the work.
The age of the housing
The Census Bureau's 2020 to 2024 estimates put the median year built at 1968 across 14,474 housing units. The 1960s are the biggest decade with 4,280 units, followed by the 1970s with 3,361 and the 1950s with 3,355.
Add the 1940s and earlier and 8,238 homes, or 56.9 percent, predate 1970. Only 933 units, 6.4 percent, date from 2000 or later. The Census does not record roof replacements, so when the roof was last done is a fair question to ask on the first call.

What we do here
Where a leak shows up at one chimney, vent or valley, roof repair traces it to that spot. Where wear runs across every slope, roof replacement comes into play.
Shared walls and fire-rated decking change the questions. Start with the county scope below, then decide between repair and replacement.
Garden-style buildings can carry low-slope sections, which are a different job from a house roof. See flat roof work, and compare coverings on the roofing materials page.
Permits
Annandale is unincorporated, so no Annandale permit counter exists. Call the county's Land Development Services on 703-222-0801 (TTY 711); its office is in the Herrity Building, Fairfax.
| Your project | Where to turn |
|---|---|
| Replacing roof shingles | On the county's no-permit list. Describe your scope to the office first. |
| Repairing a roof or chimney | Both appear on the county's permit side. Ask how your repair is classed. |
| New townhouse decking | Under 256 square feet is on the no-permit list, except where fire-rated roofs apply, as on townhomes. |
| Adding solar panels | Also on the permit side; ask first. |
| A zoning or setback question | The county's zoning staff, through the Department of Planning and Development. |
A small repair can involve more county paperwork than a full shingle swap, so the county has the last word on your scope.
The mailing address trap
No. The Northern Virginia Community College campus on Little River Turnpike carries an Annandale postal address, yet the Census Bureau places it in the separate Wakefield place. Lake Barcroft and Lincolnia are separate Census places too, and none of them is an Annandale neighborhood.
For roofing the useful point is that all of them answer to Fairfax County, so the office does not change. The parcel, not the mailing city, is what counts if a question reaches the county.
Historic and design review
Holmes Run Acres was built between 1951 and 1958 by brothers Gerald and Eli Luria, joined the Virginia Landmarks Register on December 6, 2006 and the National Register of Historic Places on March 22, 2007. A register listing is an honor, not a rule for private owners. The county's fifteen Historic Overlay Districts are a different zoning tool, and none of the names, from Bull Run Stone Bridge to Woodlawn, is Annandale. If you live in a subdivision with an association, ask it for its exterior rules in writing before ordering shingles.
Housing
Remember these are counts of dwellings; no roof age or covering is recorded.
About 31.0 percent, including 2,331 in buildings of 10 to 19 units and 784 in buildings of 50 or more.
Houses and townhouses together are about 64 percent of the 14,474 units.
9,087 of 13,891 occupied homes. The other 4,804 are rented, so the roof decision can belong to a landlord or a board.
If you manage or sit on the board of a larger building, the call starts with who signs off on scope. A garden-style roof with low-slope sections is covered on our flat roof page.
Roads and landmarks
That junction is the center of Annandale, about two miles east of the Capital Beltway. We mention it so you can place the three roads on a map when you describe where the roof is.
Mason District Park, at 6621 Columbia Pike just before Sleepy Hollow Road, is a handy reference for the neighborhoods west of the center. The county park page lists picnic shelters, fields, tennis courts and a natural area with a hiking trail.

FAQ
No. It is an unincorporated community, so Fairfax County Land Development Services at 703-222-0801 is the office, and no Annandale body or county historic overlay reviews roofs.
The age of the building does not say when the roof was last replaced. Look at the roof itself: shedding granules, curled edges, worn flashing and how many spots leak.
The county sorts work by type. The list puts shingle replacement on the no-permit side and roof and chimney repairs on the other. Describe the job to the county first.
Under 256 square feet is exempt, except where a fire-rated roof is required, as on townhomes. Ask whether yours is one.
A register listing alone does not regulate private owners, and it is not one of the county's fifteen overlay districts. Ask the county about your parcel before choosing a covering.
The Census puts it in Wakefield, but Fairfax County handles permits for both, so the office is the same. The parcel decides, not the mailing city.
Close to a third of units are in apartment-style buildings. Those roofs may need a board or property manager to approve scope first. Book a phone consultation and we can talk through what the building needs.
The owner or the building's board, not the tenant. If you rent, report the leak in writing and keep photos from the ground.
