Roofing for Brooklyn buildings
Brooklyn is a borough of brownstones, row houses, and walk-ups — which means the vast majority of its roofs are flat or low-slope, often hidden behind parapet walls.
These roofs leak in characteristic ways: at the parapet flashing, at seams and patches, around drains, and where decades of recoating have finally given out. Mariani Roofing brings the flat-roof experience Brooklyn buildings need — finding the real source of a leak instead of adding another patch on top of the last one.

Brooklyn Roofing FAQ
Local roofing questions
Do you specialize in flat roofs?
Flat and low-slope roofs are central to roofing in Brooklyn, and a core part of our work. See flat roofing.
My roof has been patched many times — what now?
Repeated patching often signals it’s time to address the underlying membrane. We’ll assess whether a proper repair or a replacement is the better value.
Can you find a hard-to-trace leak?
Yes — parapets, seams, and drains are common culprits. We trace the leak to its source. Leak repair →
