Median built 1985
About 5,100 housing units, with about 70 percent built from 1970 through 1999.
Great Falls is a house roofing market: 99.3 percent of its homes are detached houses, and the county's historic overlay list names one district here, Colvin Run Mill, and none along Georgetown Pike. King's Roofing Company in Fairfax, Virginia plans repairs and replacements around that, and around the wind this area has seen.
Houses first
Almost nothing here is a townhouse row or an apartment block, so the work is pitched house roofs: leaks at chimneys and wall joints, lifted shingles after a windy night, and full replacements when a roof wears out. The Census counts homes, not roofs, so none of these figures says what material is on any one house.
Start with roof repair when the problem is local, move to roof replacement when wear covers most of the surface, and read the materials comparison before changing the covering. Our guide, Roofing Company Great Falls VA: 2026 Costs, goes further.

Permits
Great Falls is a Census Designated Place inside Fairfax County, not a town, so there is no Great Falls permit desk. County offices answer for it.
| What you plan | Who to ask |
|---|---|
| Replacing roof shingles | Fairfax County Land Development Services, 703-222-0801. The county's residential list names shingle replacement among work that does not need a building permit; confirm for your scope. |
| Roof repair or chimney repair | Same office. The county list places roof repairs and chimney repairs on the permit side, so confirm with the office before work starts. |
| Replacing roof plywood | Same office. The list exempts less than 256 square feet (9 boards) of roof plywood unless fire rating applies. |
| Exterior work near the old mill | County Architectural Review Board, 703-324-1380, if the parcel is inside the Colvin Run Mill district |
If your neighborhood has an architectural committee, ask it before materials are ordered. The county explainer sits on service areas.

Historic review
No. The county's list of Historic Overlay Districts has fifteen names, and Colvin Run Mill is the one in Great Falls. Nothing on the list is called Georgetown Pike or Great Falls.
The Pike is a different kind of designation. It became Virginia's first Virginia Byway in 1974 and was listed on the National Register of Historic Places in 2012. Those are road honors, not zoning, and nothing on the county list ties them to roofs on private houses.
The Colvin Run district protects a mill built in the early 19th century, which the Fairfax County Park Authority bought in 1965 and which reached the National Register in 1977. Route 7 was realigned in 1941, leaving the old bend now called Colvin Run Road. The boundary is on the county's aerial map. Near the mill, call the Architectural Review Board with your address first.
Housing
About 5,100 housing units, with about 70 percent built from 1970 through 1999.
Old farmhouses are rare. Only 12.3 percent of units predate 1970, so most work is on houses from the late 20th century.
Newer houses make up 17.5 percent of units. Margins are wide on small counts, so use these as a guide.
Source: ACS 2020 to 2024 five-year estimates for the Great Falls place, not ZIP 22066. They describe homes, not roofs.
Metal
With so many houses built from the 1970s to the 1990s, a first re-roof decision is often shingle against metal. Standing seam sheds snow and rain in long panels and needs careful flashing at chimneys and dormers; shingles are simpler to repair in pieces. Neither suits every roofline; see the materials comparison.
Wind and trees
A Connection Newspapers report from April 17, 2007 describes gusts of up to 60 miles per hour on Sunday and Monday, April 15 and 16, in McLean and Great Falls, with power outages and downed trees. A large tree came down on Utterback Store Road between Georgetown Pike and Beach Mill Road. A gutter company owner quoted in the piece said gusts were blowing down siding, gutters and roof shingles across the western and northern suburbs.
FFXnow reported a Wind Advisory from 9 a.m. March 14 to 2 a.m. March 15, 2023, with gusts topping 50 mph. A tree on power lines closed Georgetown Pike at Miller Avenue, and that one outage reached 277 Dominion customers. That report describes an outage, not roof damage.
Neither article counts damaged Great Falls roofs, so read them as history, not a forecast.
Mailing address trap
Not by itself. Great Falls Park uses a McLean mailing address, and some properties along Georgetown Pike carry McLean or Herndon addresses while sitting in unincorporated Fairfax County. The parcel, not the postal city, decides which office reviews the work.

FAQ
The county's Historic Overlay District list has no Georgetown Pike district. The Pike is a Virginia Byway and a National Register road, which are road designations. Only a parcel inside the Colvin Run Mill district answers to the county Architectural Review Board.
The Census lists the Great Falls place in Fairfax County, so Fairfax County Land Development Services is the office to ask. Great Falls, Maryland across the Potomac is a different place.
Postal cities do not follow jurisdiction lines. Great Falls Park itself uses a McLean mailing address. The parcel decides who reviews roof work, so confirm with the county using your parcel.
The county pages we read do not say whether a like-for-like re-roof counts as an exterior change inside the district. Call the Architectural Review Board at 703-324-1380 with your address before planning.
The 2007 report cites gusts up to 60 mph, while the 2023 advisory cites gusts topping 50 mph. Only 2007 mentions roof shingles, and that quote covers the wider suburbs. Neither counts damaged Great Falls roofs.
No. Only 78 of about 5,100 units predate 1940, and about 70 percent were built from 1970 through 1999. The Census does not record roof age, so judge a roof by its condition.
County guidance lists replacing roof shingles as work that does not need a building permit, but roof repairs and chimney repairs are on the permit side. Confirm your exact scope at 703-222-0801.
