Flat and low-slope roofs are common on NYC row houses, multi-family buildings and commercial properties, and they are prone to ponding water, cracked membranes and failed flashing. Homex Builders provides roof waterproofing for property owners across the Bronx, Manhattan, Brooklyn, Queens, Staten Island, Yonkers, Long Island and New Jersey.

We inspect the roof surface, seams, drains and flashing, repair problem areas, and apply waterproof coatings or membranes suited to your roof. A properly waterproofed roof stops leaks, reflects heat and can add years to the life of your existing roofing system.

What Our Roof Waterproofing Includes

Roof waterproofing projects typically include:

Roof Coatings

Elastomeric and reflective coatings that seal the roof surface and reduce heat gain.

Membrane & Seam Repair

Repairing blisters, splits and open seams in roofing membranes.

Flashing & Drains

Resealing flashing at walls, parapets, vents and drains where most roof leaks start.

Coating a roof that is still structurally sound is often far less expensive than a full replacement, and it reduces the risk of costly interior water damage.

Frequently Asked Questions

Can a roof coating stop leaks?

Yes, when the roof is structurally sound. We repair damaged areas and flashing first, then apply a coating that seals the whole surface.

How long do roof coatings last?

Quality coatings typically last many years, and many can be recoated to extend protection further.

Is my roof a good candidate for waterproofing?

Roofs with limited damage and dry insulation are good candidates. If the roof deck or insulation is saturated, replacement may be the better option.

How much does roof waterproofing cost in NYC?

Pricing depends on the size of the area, the condition of existing materials, access and the materials you choose. We provide a free on-site estimate with a clear scope and price before any work begins.

Do I need a permit for this work?

Roof coating and minor repairs usually do not require a permit. Full roof replacement or structural work may. We help confirm requirements for your building.
