Baltimore City & Baltimore County, Maryland
Flat rowhome roofs, historic slate and shingle roofs across Baltimore City & County
Baltimore Roofing is a roofing company in Baltimore, Maryland that repairs and replaces roofs on rowhomes, historic homes and commercial buildings. We serve Baltimore City ZIP codes from 21201 to 21239 and nearby Baltimore County communities like Towson, Parkville and Dundalk.
Most roofers in Baltimore City spend their days on flat roofs. Brick rowhomes in Canton, Hampden, Federal Hill and Highlandtown have low-slope roofs that share seams and parapet walls with the house next door, so a leak on one roof can show up in a neighbor's ceiling. Our crews know how to tie a new EPDM or modified bitumen roof into the adjoining roofs without creating a new weak spot.
North of the city, the roofs change. Towson, Parkville and Perry Hall are full of shingle roofs on colonials, ranches and Cape Cods, while Roland Park, Homeland and Guilford have slate roofs that can outlast the house when they are repaired correctly. As Baltimore roofing contractors, we work on all of them, from a single cracked slate to a full tear-off.
Our office sits in North Baltimore near Belvedere Square and Loch Raven Boulevard (21212), a few minutes from I-695 and I-83, so we reach most of the city and county quickly when a roof is leaking.

The local weather is hard on roofs in both directions: humid, stormy summers and winters that swing above and below freezing.
~41 in
Baltimore gets roughly 41 inches of precipitation a year over more than 110 wet days. Flat rowhome roofs that hold ponding water after each storm break down years early.
~97 nights
Water gets into small cracks, freezes, expands and thaws again. That freeze-thaw cycle splits old slate, lifts shingles and opens flashing around chimneys and parapets.

Summer heat bakes dark flat roofs and dries out shingles. A silver or elastomeric roof coating reflects heat and adds years to a sound flat roof.
Nor'easters and the remains of tropical storms add wind-driven rain and occasional heavy snow. After any big storm, a quick roof inspection catches damage before it turns into a ceiling leak, and our storm damage repair team documents everything for your insurer.
Baltimore has more rowhomes than almost any American city, and nearly all of them have flat or low-slope roofs. We repair and replace EPDM rubber, TPO and modified bitumen roofs, fix ponding with tapered insulation, and rebuild the flashing where your roof meets the parapet and the neighbor's roof.
Common in Canton, Hampden, Federal Hill and Dundalk.
Rowhome roofingSlate roofs on older homes often last a century or more when cracked slates, rusted nails and worn copper flashing are replaced in time. We match slate by color and size, and we repair before we recommend replacement.
Homes in city historic districts may need review by the Commission for Historical and Architectural Preservation (CHAP) before exterior roof work. We handle that paperwork for projects in Roland Park and other historic neighborhoods.
Slate roofingBaltimore City is an independent city, separate from Baltimore County, and each has its own permit office. Inside the city, building permits come from the Department of Housing and Community Development (DHCD), mostly online or at the One-Stop-Shop on East Fayette Street. In Towson, Parkville, Catonsville and the rest of the county, permits go through the county's Department of Permits, Approvals and Inspections.
Small repairs like replacing a few shingles usually don't need a permit, while a full roof replacement or structural work generally does. Maryland also requires contractors doing home improvement work on houses with one to three units to hold a Maryland Home Improvement Commission (MHIC) license. Ask any roofing contractor in Baltimore, MD for their MHIC number before you sign.

Good roofers are easy to check. Before you hire anyone, confirm these five things:
For shops, offices, churches and multi-unit buildings, we install and repair TPO, EPDM and modified bitumen systems and set up maintenance plans that catch small problems before they reach tenants. See our commercial roofing services or ask about metal roofing for long-life projects.
Most flat rowhome roofs cost about $7,000 to $14,000 to replace, and asphalt shingle roofs on detached homes run about $10,000 to $22,000. Size, pitch, old layers and flashing work move the price. We give a written price after a free inspection.
A full roof replacement generally needs a building permit from Baltimore City DHCD, while small repairs usually do not. Homes in city historic districts may also need CHAP review. In Baltimore County, permits come from the Department of Permits, Approvals and Inspections. We pull the permit for you.
A well-installed EPDM or modified bitumen flat roof usually lasts about 15 to 25 years here. Ponding water, poor parapet flashing and skipped coatings shorten that. A reflective coating every several years helps it reach the top of that range.
Rowhome roofs often share seams at the party wall, so the leak may start on either roof. We inspect both sides where we can, find the source and explain it in writing so both owners can agree on the repair.
Usually, yes. Slate itself can last a century; most leaks come from broken slates, failed nails or worn flashing. Replacing those is far cheaper than a new roof. We only recommend replacement when the slate itself is failing across the roof.
Most Maryland policies cover sudden damage from wind, fallen trees or hail, but not wear and tear or slow leaks from age. We photograph and document storm damage and can meet your adjuster on site.
Yes. Call (410) 623-5534 any time for an active leak. We tarp or temporarily seal the roof to stop the water, then schedule the permanent repair.
