Homes & buildings
Flat Roof Replacement for Brooklyn Buildings
We replace flat roofs on brownstones, multifamily buildings, mixed-use properties and commercial buildings.
The scope depends on how many old roof layers there are, the condition of the deck and the building’s requirements. On brownstones and rowhouses, we plan around parapet walls and shared roof lines. On occupied buildings, we schedule the work to keep the building protected and disruption low.

FAQ
Flat Roof Replacement FAQs
How much does flat roof replacement cost in Brooklyn?
Flat roof replacement costs about $8 to $35 per square foot. A typical Brooklyn brownstone roof of about 1,000 square feet costs $8,000 to $12,000. Your exact price depends on the material, roof size and deck condition.
How long does a flat roof replacement take?
Most replacements on Brooklyn homes take a few days. Larger buildings, deck repairs or bad weather can add time. We give you a schedule in your estimate.
Does the existing membrane need to be removed?
Often, yes. We check how many layers are on the roof and their condition, then recommend a full tear-off or other approach.
Will the roof deck need replacement?
Not always. We inspect the deck once the old roof is off and replace only the damaged sections.
Which material is suitable for a new flat roof?
It depends on your building, roof use and budget. EPDM, TPO, PVC, modified bitumen and built-up roofing are all options, and we explain which fits your roof.
Does flat roof replacement require a permit in NYC?
It depends on the scope. Replacing roofing layers on top of the existing deck may not need a permit if no added insulation is required by the energy code. Replacing the deck usually does, and landmark buildings may need extra approval. We confirm requirements before work begins and file NYC DOB permits when the job needs them.
