Houses and townhome-type homes together make up fewer than one in five Tysons homes.
Almost four of every five homes in Tysons are in buildings of five or more units, and two of every three households rent. In that kind of place the person under the roof is rarely the person who decides about it: a condo board, a landlord or a management company is. King's Roofing Company, based in Fairfax, Virginia, helps you work out who that is and what the county expects before a roof is touched.
Who decides
The Census Bureau's 2020 to 2024 estimates for the Tysons place count 15,436 homes. Single-family houses, detached and attached together, are 2,793 of them, or 18.1 percent. The rest are apartments and condominiums, and 8,173 are in buildings of 50 or more units. Those roofs have an owner of record, rarely the person who calls about a drip.
Houses and townhome-type homes together make up fewer than one in five Tysons homes.
That is 25.6 percent. Another 498 were built from 2020 on, so the roofs range from aging to nearly new, and the median is 1995.
Another 1,209 homes are in buildings of 20 to 49 units. Margins of error are large.
Remember that these are housing counts. Roof age and material are not in the data.
Condos and associations
The act defines common elements as all portions of the condominium other than the units. Whether a given roof is one depends on the recorded declaration, bylaws and plats, which the act calls the condominium instruments, so read yours before assuming.
Unless those instruments say otherwise, the executive board must study reserves at least every five years for the capital components it has to repair, replace or restore, review the result at least annually, and adjust the budget and assessment to keep reserves sufficient. In practice the board, not one owner, sets when a common roof is replaced. Apartments work differently: no association is involved, and the landlord decides.
Nothing here claims commercial work, high-rise work or any building size.

What we do here
See roof repair for leaks and roof replacement for when patching stops paying.
Mid-rise roofs and rooftop additions are often low-slope. Start with flat roof to see how the coverings differ.
Boards can weigh options on materials before a vote.
Permits
Tysons is unincorporated, so one county office answers for every address.
| What you plan | Who to ask |
|---|---|
| New shingles on a house or townhome | Land Development Services, 703-222-0801. Its residential list shows replacement of roof shingles as work without a building permit. Confirm for your parcel. |
| Roof repairs on a house or townhome | Same office. The residential list places roof repairs under miscellaneous work that does need a permit. |
| Townhome roof deck replacement | Same office. Plywood replacement under 256 square feet is exempt unless the deck must be fire rated, and the page uses townhomes as its example. |
| Repairs on a commercial or multifamily building | Same office. The commercial list names roof repairs, and also balcony repairs and waterproofing, as permit work. |
| Re-covering a larger building | Same office. Only replacement of less than 100 square feet of roof covering appears on the commercial no-permit list. The state code uses a slightly different wording, 100 square feet or less. |
| Solar panels | Same office. Both lists name them as permit work. |
Why the difference between houses and bigger buildings? The statewide building code exempts an unlimited amount of roof covering replacement only for Groups R-3, R-4 and R-5, and for other groups only 100 square feet or less. The county's pages do not list multifamily re-roofing separately, so ask which group your building falls in. Its counter is in the Herrity Building in Fairfax; the page lists weekday hours that start later on Fridays, at 9:15 a.m.
Address trap
Tysons is a Census place of about 4.3 square miles with 26,374 residents in 2020, and it sits between McLean and Vienna. Mail commonly names McLean or Vienna, and the county's Tysons planning boundary does not match the Census place, so a mailing line says little about the exact parcel. Pimmit Hills next door is a separate Census place, not part of Tysons.
Historic review
The county's Historic Overlay Districts page says the Board of Supervisors created thirteen in 1969 and has since added two, for fifteen in all. Tysons is not among the names on that page. The state code allows a permit to be required for reroofing inside a locally designated historic district, which would be the exception. The county's Architectural Review Board administrator, 703-324-1380, can check an address.
Low-slope roofs
The Census does not say how many Tysons roofs are flat, but low-slope roofs are normal on larger buildings generally. They shed water slowly, so drains, scuppers and the flashing along a parapet carry most of the load. When a leak shows up in a top-floor unit, the entry point is often far from the stain.
TPO, EPDM, PVC and modified bitumen are built and repaired differently. Our flat roof page compares the coverings, including where a coating helps, and boards can compare options on materials. Ask every bidder how they will find wet insulation.
Weather
The county's local design load criteria list a ground snow load of 25 pounds per square foot and an ultimate wind speed of 115 mph for Risk Category II and residential buildings. Those are design inputs, not a promise about any one roof.
FFXnow reported that a storm on June 19, 2025 left more than 70,000 Fairfax County residents and businesses without power at its height, with winds reportedly reaching 66 mph at Dulles. The article covers outages and trees, with nothing on Tysons roofs. Photograph from the ground first; the storm damage repair guide explains why.
