Baltimore Premium Roofing provides professional roof leak repair in Baltimore, MD for residential and commercial properties across Central Maryland. On a rowhouse the leak is hardly ever in the middle of the roof. It is at a wall.
Base flashing at the party wall, an open coping joint, a rusted scupper, or a neighbor's failed detail two feet from your brick.
Water that enters at a party wall travels along the top of a joist that runs the whole width of the house, so the stain appears in a room that has nothing to do with the entry point.
Chasing the stain up through the ceiling is how people end up cutting three holes in good plaster. We start at the wall line on both sides and work inward, because that is the order the water uses.
The other Baltimore complication is that the origin may not be on your property. A vacant next door with an open roof will keep charging the shared brick with water no matter what we install on your side. Baltimore City had 13,796 Vacant Building Notices on file in October 2024, and the city publishes the register daily on Open Baltimore, so we can usually tell you within a minute whether the house beside you is one of them.
When that is what is happening we say so plainly and we do not sell you a repair that cannot work. The realistic options are a saturated-masonry treatment on your own face of the wall, a conversation with the owner next door, or a complaint to the city. None of those is a roofing invoice, and pretending otherwise would just move your money without moving the water.
Where the fault is genuinely ours to fix, the repair is specific. We strip back to sound material, dry the substrate, and rebuild the termination with a proper base ply turned up the wall and a surface-mounted reglet with sealant and fasteners into your own masonry, never into the half of the wall that belongs to the house next door. Cold-applied and self-adhered products only.
You get photographs of what was opened, what was found and what went back, taken from the same three positions each time. If the same detail fails again we want to be able to compare pictures rather than memories, and so should you. Repairs on sound roofs carry a written workmanship warranty; repairs on roofs we have told you are finished do not, and we will say which one you have.
Our insured team brings the right materials and equipment to every job — self-adhered modified bitumen cap sheets, party-wall base flashing terminated in a surface-mounted reglet, through-wall scuppers with sheet-metal collector heads, parapet coping caps set on cleats with sealed joints, tapered polyisocyanurate crickets pitched to the rear outlet, cockloft framing with joist ends pocketed into brick — and backs the work with a written workmanship warranty. We serve Baltimore and nearby communities including Dundalk, Towson, Catonsville, Essex.

Materials, equipment and how we do roof leak repair
The difference between roof leak repair that lasts and roof leak repair that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with self-adhered modified bitumen cap sheets, party-wall base flashing terminated in a surface-mounted reglet, through-wall scuppers with sheet-metal collector heads, parapet coping caps set on cleats with sealed joints, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Baltimore job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in Central Maryland means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Baltimore Chooses Baltimore Premium Roofing
- ✓We scope the two party walls before the field, because on a Baltimore rowhouse the roof ends at somebody else's building on both sides.
- ✓No open flame on an occupied attached block. Self-adhered and cold-applied systems only, and that commitment is written into the proposal.
- ✓Every proposal states your position in the row, because a middle house, an end unit and a house beside a vacant lot are three different roofs.
- ✓Coping, cornice and the rear outlet are priced as separate lines from the membrane, since that is where rowhouse roofs actually fail.
