—A Closer Look
Waterproof It Right, Protect It Longer
Our two core roof waterproofing services, and how we approach each one.
— Membrane Protection
Flat Roof Waterproofing
Flat roofs are especially vulnerable to ponding water, seam failure, and flashing leaks around skylights and roof penetrations. We waterproof flat roofs using durable membrane materials and advanced application techniques, sealing every seam and edge to prevent structural damage and extend the roof’s useful life.
— Protective Coating
Waterproof Roof Coating
A professionally applied waterproof roof coating creates a strong, weather-resistant barrier over an existing roof surface, guarding against rain, UV exposure, and leaks. Beyond stopping water intrusion, a quality coating improves energy efficiency and adds years to a roof’s lifespan without the cost of a full replacement.
— Flashing waterproof
Skylight & Flashing Waterproofing
Protect vulnerable roof areas with professional roof waterproofing services designed to prevent leaks around skylights, flashing, vents, and other roof penetrations. Our team seals gaps, repairs damaged flashing, and applies reliable waterproofing solutions to help keep your property dry and protected from weather damage.

— Questions
Frequently Asked Questions — Roof Waterproofing NYC
Roof waterproofing is the process of applying membranes, sealants, or coatings to a roof surface to stop water from penetrating into the structure below. It’s used on flat and low-slope roofs, where standing water and seams make leaks more likely than on pitched roofs.
A quality waterproof roof coating typically lasts 5 to 10 years before it needs to be reapplied, depending on the coating type and how much sun and foot traffic the roof gets. Regular inspection lets us catch thinning spots and recoat before a leak develops.
Roof repair fixes a specific problem — a puncture, a failed seam, damaged flashing — while roof waterproofing applies a continuous protective layer across the whole roof surface to prevent leaks from developing in the first place. Many jobs involve both: repairing existing damage, then waterproofing to protect the repair.
Watch for ponding water that doesn’t drain within 48 hours, visible cracks or blistering in the membrane, interior ceiling stains, and a roof coating that’s chalking or peeling. Any of these mean water is getting past the roof’s protective layer.
Most waterproof roof coatings should be inspected annually and reapplied every 5 to 10 years, or sooner if the surface shows wear from UV exposure or ponding water. Reapplying before the coating fully breaks down is far cheaper than repairing a leak afterward.
