- Who We Are
A Residential Flat Roofing Company Built for NYC Buildings
Avenue NY Roofing is a licensed and insured flat roofing company in NY with more than 20 years of experience on New York City rooftops. Most homes here sit under a flat or low-slope roof, from Brooklyn brownstones to Queens attached houses and Bronx walk-ups. That is the work we know best. As a residential flat roofing company, we install new roofs, fix leaks and seal roofs against water. We are certified installers and licensed contractors, so your roof qualifies for manufacturer-backed warranties. Our flat roofers understand NYC codes, parapet walls, shared roof lines, and the freeze-thaw cycles that crack weak membranes. We give honest advice and fair written pricing, and we only suggest a full replacement when a repair will not last.

Flat Roofing Services for NYC Homes and Buildings
From new installs to emergency leak repairs, our flat roofing contractors handle every stage of your roof’s life.
EPDM Flat Roof Installation
Our EPDM rubber membrane stays flexible in any weather, meets cool roof rules with white EPDM or a coating, and lasts 25+ years.
TPO Flat Roofing
TPO, a white heat-welded membrane, meets NYC cool roof rules, has strong seams, and cuts summer cooling bills on your top floor.
Modified Bitumen Flat Roofs
Modified bitumen is a multi-layer asphalt roof built for foot traffic, applied torch-down or cold with reflective cap or coating.
Flat Roof Replacement
Soft spots or wet insulation mean it’s time. We strip failed layers, fix the deck, and add a new system with tapered insulation.
Flat Roof Repair and Leak Detection
Not every leak needs a new roof. We find the source, from split seams to failed flashing or clogged drains, and fix it properly.
Flat Roof Maintenance Plans
Most flat roof failures start small. Yearly or twice-yearly checkups clear drains, seal seams, and catch issues before they leak.
Our Flat Roofing Process
Our flat roof installers follow a simple, proven process that keeps your project clean and on schedule.
Flat Roofing Cost in NYC
Every flat roof is different, so the flat roofing cost in NYC depends on roof size, the membrane you choose, deck condition and roof access. We price each job after a free inspection, so you only pay for what your roof actually needs. Here’s a general guide to help you plan your budget with confidence and avoid any surprises:
EPDM Flat Roof
EPDM roofs cost $10 to $16 per square foot in NYC. White EPDM or reflective coatings meet cool roof rules.
TPO Flat Roof
TPO roofs cost $11 to $18 per square foot. Their white surface meets cool roof rules without extra coating costs.
Modified Bitumen Flat Roof
Modified bitumen roofs cost $10 to $17 per square foot in NYC. They’re durable, budget-friendly and handle foot traffic well.
Flat Roof Repair & Waterproofing
Repairs run $400 to $2,500; coatings cost $3 to $7 per square foot. Wet or two-layer roofs need a tear-off.

- FAQs
Your Roof Repair Questions Answered
Each has strengths. EPDM is flexible and long-lasting in cold weather. TPO is white and energy-efficient, which helps with cool roof rules. Modified bitumen handles foot traffic best. We recommend the right one after inspecting your roof.
A well-installed flat roof usually lasts 20 to 30 years. EPDM and TPO often reach 25 years or more, and modified bitumen about 15 to 20. Good drainage and regular checkups help your roof last longer.
Ponding usually comes from clogged drains, a sagging deck or poor slope. Water that sits for more than 48 hours speeds up wear and can cause leaks. We fix it with drain repairs, tapered insulation or deck work.
Often, yes. If the deck and insulation are dry and the membrane is mostly sound, a waterproof coating and new flashing can add years of life. If the roof is wet underneath, replacement is the safer choice.
In most cases, yes. The NYC Building Code, enforced by the NYC Department of Buildings, requires most new and replaced low-slope roofs to have a reflective cool roof surface. White TPO meets it on its own; black EPDM or modified bitumen needs a white membrane or an ENERGY STAR-rated coating. We'll tell you which option fits your building.
