Half the housing in Baltimore City is attached, and four homes in ten were built before 1940. Most roofs here are rowhouse roofs, and dozens of neighborhoods are city historic districts.
Why local actually matters here
A Baltimore mailing address does not tell you whether the house is in Baltimore City, and in this town that is the first thing we check.
Baltimore is an independent city, not part of Baltimore County, and the ZIP codes do not follow the line. About 41% of 21209 lies in the city and the rest in the county. 21212 is split 55/45, and 21206 and 21239 are each roughly two-thirds city. Two houses with the same ZIP can answer to different governments, so we establish which side of the line your address is on before anything is quoted.
Inside the city the housing is overwhelmingly attached. Census figures put single-family attached homes at just over half of all housing units, with detached houses at about one in seven. The city’s own preservation guidelines note that many rowhouses have shed or slanted-flat roofs. Those are membrane roofs, not shingle roofs, and the detail at the party wall matters as much as the middle of the roof. Water that gets past a shared wall is your neighbor’s problem too.
The stock is also old. Around 41% of homes in the city were built in 1939 or earlier, and more than half predate 1950. On a roof that age the question is less about the surface and more about what is underneath it: the decking, the parapet flashing, and a drain or gutter that may be carrying more water than it was sized for. CHAP’s guidelines point out that heavy short bursts of rain can overwhelm a rowhouse with one gutter for the entire roof, or back water up under a flat roof membrane. We look at the drainage before we talk about materials.
Then there are the historic districts. Canton, Hampden, Federal Hill, Fells Point, Roland Park and Mount Washington are all on the city’s list of local historic districts, and exterior alterations to designated properties go through CHAP’s Authorization to Proceed review. Its guidelines treat a flat roof nobody can see from the ground very differently from a slate or metal roof on the front of the house. We will tell you plainly if your address is in a district, because finding out afterwards is expensive.
Permit requirements come from Baltimore City, which is its own jurisdiction separate from Baltimore County, and depend on whether the work is like-for-like or structural. We confirm what your address needs before work starts.

What we actually find here
None of these are guesses about your house. They are what this housing stock, at this age, keeps producing.
That is the most common reason people here call us. We go up, photograph what is really there, and tell you if a repair will hold. A second opinion costs nothing and nobody here works on commission.

“It’s been great working with Dmitry and Bravo roofing for several years now. They did a full tear off and replace of my flat roof back in 2019. I had a leak last year and Dmitry came out to inspect. He found that an old roof antenna had fallen off and punctured it.”
Tony DeBraccio · Google“I highly recommend Bravo for any kind of roof repair or construction. Dmitry, the business owner, is meticulous and detailed. He personally assessed the leaking overhang roof in our old house and delivered a thorough and economical solution.”

The ZIP will not always tell you. 21209 is mostly Baltimore County, 21212 is split roughly 55/45, and 21206 and 21239 are about two-thirds city. We check the street address, because the answer decides whose permit and review process applies.
That is a Baltimore City question, and the city is its own jurisdiction separate from Baltimore County. It depends on whether the work is like-for-like or structural. We confirm what your address needs before work begins.
No. Shingles need pitch to shed water, and a shed or slanted-flat rowhouse roof does not have enough of it. That roof needs a membrane, and the quote should say which one and how the party wall and the drain are being handled.
Exterior alterations to designated properties in Baltimore City go through CHAP’s Authorization to Proceed review. CHAP’s guidelines treat a flat roof that cannot be seen from the ground very differently from a visible slate or metal roof, so it is worth knowing which one you have before choosing a material.
On attached houses it often makes sense to at least talk about it, because the detail at the shared wall belongs to both roofs. We are happy to look at both and tell you honestly whether yours needs doing yet.
Often it can. CHAP’s own guidelines note a slate roof may last more than a hundred years. Whether a repair will blend depends on the slate and what is still available, and we will tell you before you commit.
