Houses
A leak trace starts at chimneys and valleys. Roof repair explains how, and roof replacement covers the point where patching stops making sense.
Bethesda is not a town, so Montgomery County is the only office for a Bethesda parcel. The towns around it are another story: the county's own list puts them in three different orders, with the town first in Kensington, the county first in Somerset, and the county alone in Friendship Heights and Oakmont. King's Roofing Company, based in Fairfax, Virginia, starts every Bethesda call by asking which of those a street belongs to.
Approval order
The Department of Permitting Services keeps a page that sorts municipalities by approval sequence. Kensington, Chevy Chase Village, the Village of Drummond and Takoma Park sit under "City Approval is Required Prior to County Application". The Town of Chevy Chase, Chevy Chase Sections 3 and 5, Glen Echo, Martin's Additions and Somerset sit under "County Permit Required Prior to City Approval". The Village of North Chevy Chase is listed under "Both County and City Approval is Required". Friendship Heights and Oakmont are listed as "County Permit Only".
Bethesda itself appears on none of those lists because it is an unincorporated community with no government of its own. The page also says the county's rules do not replace a town's, so the order matters before you book anyone.

What we do here
A leak trace starts at chimneys and valleys. Roof repair explains how, and roof replacement covers the point where patching stops making sense.
Shared walls and association rules shape the scope. Read the covenants first, then compare coverings on materials.
Apartment and condo buildings can have flat sections, covered on flat roof. The owner may be a board, so we talk with a manager or board member. For the county's roof-reflectance rule on apartment and commercial roofs, see EPDM roofs in Bethesda.
Permits
Ask the office for your address. This table is a map, not an answer.
| What you plan | Who to ask |
|---|---|
| New roof covering on a Bethesda house | Montgomery County Department of Permitting Services, MC 311 at 240-777-0311. Its list says you "most likely will not need a permit" for "Roof (covering only)". Confirm with the office. |
| Framing, rafters or new roof openings | Same department, before the work is scoped. Structural changes are not on the no-permit list. |
| Roof on a Kensington street | Town of Kensington, 3710 Mitchell Street, 301-949-2424, before the county application. |
| Somerset or Town of Chevy Chase | The county permit comes first, then the town. Town of Chevy Chase office: 301-654-7144. |
| Marked historic property | Historic Preservation Office, 301-563-3400. |
The county's service counter is at 2425 Reedie Drive, 7th Floor, Wheaton, open weekdays 7:30 a.m. to 4 p.m., and the page says no appointment is necessary. It also warns that its list does not include municipality and homeowner association rules.

Mailing address
No. Cabin John Regional Park is at 7400 Tuckerman Lane with a Bethesda mailing line, and the Town of Oakmont uses a Bethesda 20817 box, yet Oakmont is a separate municipality on the county's list. Meanwhile, several towns people call "near Bethesda" use Chevy Chase 20815 addresses. The mailing city is a hint only. The parcel decides who reviews the roof.
Neighbors who want their own pages have them: Chevy Chase, Kensington and Potomac. Potomac is a separate community with no town government, so it follows the county alone.
Historic and design review
Potomac Overlook carries a Bethesda 20816 address, not a Potomac one. The County Council voted to approve its historic district designation on April 19, 2022. Montgomery Planning says local designation requires design review by the Historic Preservation Commission for any major exterior changes.
For designated properties, Montgomery Planning lists work that does not need the commission. It includes "roof repairs" with "materials and design matching what is already in place". The page does not say where a full re-roof falls, so on a designated house call 301-563-3400 before ordering shingles. A change of roofing material is the kind of exterior change that gets reviewed.
The same page reminds owners that some local governments review changes before a Historic Area Work Permit, naming Brookeville, Chevy Chase Village, Garrett Park, Kensington and Takoma Park. The historic list does not name every Bethesda lot, so use the county map tool with your address instead of assuming. Homeowners associations are separate again, and the county says it does not enforce covenants.
Housing
Census Bureau estimates for the Bethesda place, 2020 to 2024.
An estimated 15,242 units, 50.6 percent, date from before 1970. Another 4,782 were built in 2010 or later.
That is 52.9 percent of units. Attached single homes are 1,173 (3.9 percent), so house and townhouse roofs are a little over half.
Buildings of 50 or more units hold 34.6 percent of homes. Owner-occupied homes number 17,868 against 10,069 rented.
The Census counts homes, not roofs. Roof age and material are not in the data.
Weather and trees
NBC Washington reported that a lightning-struck tree on Avalon Drive caught fire, brought down wires and blew a transformer during Sunday storms. Pepco confirmed 40 customers were affected and expected repairs by midnight. The story describes an outage, not roof damage. A resident quoted in it said above-ground wires and limbs cause outages there "all the time".
That is a reason to look at the trees over your own roof. After a storm, check from the ground for lifted shingles and limbs resting on slopes, and see our storm damage repair guide.
Roads
Downtown Bethesda is centered where Wisconsin Avenue, Old Georgetown Road and East-West Highway meet. Edgemoor, laid out in 1912 on 183.5 acres, and Battery Park both lie close to that crossing. Giving us the nearest crossing and the street name is faster than a ZIP code when we place a parcel.

FAQ
No. It is unincorporated, so the Montgomery County Department of Permitting Services in Wheaton is the office. Call MC 311 at 240-777-0311 for your address.
The county's municipality page lists Kensington under approvals required prior to the county application. Call the town at 301-949-2424 first.
The county lists them as county permit first, then city approval. Confirm the sequence with the town office before you order materials.
The county list marks both "County Permit Only". Oakmont has a Bethesda 20817 box, so a Bethesda mailing line does not mean a town has no say.
Its listed address is Bethesda 20816. The County Council approved its historic district on April 19, 2022, so major exterior changes go through design review.
Montgomery Planning lists roof repairs with matching materials and design as not needing commission involvement. A full re-roof is not addressed, so call 301-563-3400.
The NBC Washington report describes a tree fire, a blown transformer and 40 customers without power. It does not describe roof damage.
The median home was built in 1970 and 50.6 percent date from before 1970, but 4,782 units are from 2010 on and the Census cannot say which roofs were replaced. Condition is the test.
