Flat Roofing for NYC's Urban Buildings

Flat and low-slope roofs are the standard on NYC tenements, brownstones, commercial buildings, and rooftop additions. RoofingServiceNY.com installs and repairs membrane roofing systems across Manhattan, Brooklyn, Queens, the Bronx, and Staten Island, with a focus on solving the drainage issues that cause most flat roof failures.

EPDM Rubber Roofing

EPDM is a durable, cost-effective single-ply membrane widely used on NYC flat roofs. We install fully adhered EPDM systems and repair seam separations and punctures on existing roofs.

TPO & PVC Membrane Roofing

TPO and PVC membranes offer a reflective, energy-efficient surface with heat-welded seams that create a permanently bonded, watertight roof — a popular choice for both residential extensions and commercial buildings.

Modified Bitumen

For multi-layer built-up roof systems, we install torch-down and cold-applied modified bitumen, a proven option for buildings that need a heavier-duty, multi-ply roofing system.

Ponding Water & Drainage Correction

Standing water is the single biggest cause of premature flat roof failure. We correct improper slope with tapered insulation systems and ensure drains and scuppers are properly sized and unobstructed.

Frequently Asked Questions

Why does my flat roof keep getting ponding water?

Usually the roof lacks proper slope or drains are undersized or clogged. We correct this with tapered insulation systems that direct water to drains.

What's the best flat roofing material for NYC buildings?

TPO and PVC offer heat-welded seams and a reflective surface, EPDM is durable and cost-effective, and modified bitumen suits multi-layer builds. The right choice depends on your building and budget.

How long does an EPDM or TPO flat roof last?

Typically 20 to 30 years when properly installed and maintained, compared to 15 to 20 years for older built-up systems.

Can you waterproof a rooftop deck or amenity space?

Yes. We install waterproofing membranes rated for foot traffic and planters beneath pavers or decking.
