Flat roof repair & replacement in Brooklyn
Brooklyn row houses sit side by side under long, connected flat roofs. When one leaks, the cause can be your parapet, your chimney or your neighbor’s seam.
On attached row houses, the roof line runs across the block, separated only by low parapets. Leaks often start at those dividing walls, at chimney flashing, at skylights and hatches, or where one owner’s roof meets the next. A good repair ties properly into the neighboring roof instead of leaving an open seam at the property line.
We repair and replace flat roofs on brownstones, row houses and walk-ups with EPDM rubber or modified bitumen, and we look at the parapets and chimneys at the same time, since on a Brooklyn row house the roof and the masonry above it usually fail together.

What Brooklyn owners should know
General information only, not legal advice. Confirm requirements with the issuing NYC agency.
Roof replacement rules
Local Laws 92 and 94 of 2019 can require solar or green-roof areas on roof replacements, and the energy code generally requires reflective surfaces on many low-slope roofs. We’ll flag what applies.
Landmarks
Rooftop additions and visible changes in historic districts may need LPC review; like-for-like roofing generally isn’t visible from the street.
HPD violations
Roof leaks into rental units can lead to HPD violations.
Fire safety
Torch-applied roofing has fire-safety requirements; self-adhered systems are an alternative on some roofs.

Roofing questions in Brooklyn
My leak might be coming from the neighbor’s roof. Can you tell?
Often, yes. We inspect the shared parapet, the transition between roofs and the flashing, and explain what we see.
EPDM or modified bitumen for a row house?
Both work well on Brooklyn flat roofs. We’ll explain the tradeoffs for your roof, traffic and budget.
Can you also fix the parapet while you’re up there?
Yes. Coping, repointing and parapet flashing are often part of the same job.
