Roof Replacement in Brooklyn
Most Brooklyn roofing is low-slope work behind a parapet, and most Brooklyn roofing problems start at the parapet rather than in the field of the roof. We replace membrane roofs on brownstones and rowhouses across the borough, and pitched roofs on the detached stock in Bay Ridge, Marine Park and Ditmas Park.
What roofing in Brooklyn actually involves
Every market we work in has its own building stock, its own permitting process and its own way of failing. Here is what shapes the work here.
The building stock
The brownstone and rowhouse belt through Park Slope, Bed-Stuy, Carroll Gardens and Crown Heights is almost entirely flat-roofed: a membrane deck, a parapet on three sides, and a cornice that is often the most fragile part of the building. Ditmas Park and Prospect Park South break the pattern with large detached Victorians carrying complex pitched roofs, turrets and original slate. Bay Ridge and Marine Park are mostly attached brick with a mix of low-slope and shallow pitch.
Permits and approvals
NYC DOB filing applies borough-wide. Brooklyn has an unusually large number of designated historic districts — Park Slope, Brooklyn Heights, Fort Greene, Cobble Hill and more — where anything visible from the street, cornice repairs included, goes through the Landmarks Preservation Commission. On rowhouses we also coordinate roof access and party-wall flashing with the adjoining owner, which is routine here and rare elsewhere.
Weather and exposure
Flat roofs in Brooklyn fail at the details, not the middle: parapet copings that have opened up, cornice junctions, and drains that back up under heavy summer rain and pond water against the wall. When we quote a Brooklyn membrane job the perimeter and the drainage carry more of the price than the field, because that is where the money actually needs to go.

Brooklyn roofing questions
The questions we hear most from Brooklyn homeowners before they book an estimate.
Which membrane is best for a Brooklyn brownstone roof?
EPDM and modified bitumen both perform well on brownstone and rowhouse roofs. The membrane matters less than the details: parapet copings, the cornice junction and the drains are where these roofs fail, and that is where the specification and the price concentrate.
Does Landmarks need to approve roof work in Park Slope or Brooklyn Heights?
In designated historic districts such as Park Slope, Brooklyn Heights, Fort Greene, Cobble Hill and Prospect Park South, anything visible from the street, including cornice repairs, goes through the Landmarks Preservation Commission. Membrane work that is not visible from the street generally does not, but we confirm for the specific address.
Do you need my neighbor’s permission to replace a rowhouse roof?
Not permission, but coordination. The flashing at the party wall is shared, and we notify the adjoining owner before work starts and arrange roof access. It is routine on Brooklyn rows and we handle that conversation.
Do you replace pitched roofs in Brooklyn?
Yes. The detached Victorians in Ditmas Park and Prospect Park South, and the homes near Shore Road in Bay Ridge and around Marine Park, carry pitched slate, cedar and shingle roofs, and we replace all three.
