Complete Flat Roofing Services Across Long Island

From routine upkeep to full system overhauls, we handle every aspect of flat roofing under one roof. Our services are available for residential and commercial clients throughout Long Island.

Flat Roof Inspection

Catching a problem early is always cheaper than dealing with the fallout later. Our inspection process goes beyond a surface-level walkthrough. We assess the condition of the membrane, insulation, flashing, drainage points, and underlying structure,giving you an accurate picture of your roof’s current state and what it needs to stay in top shape.

Flat Roof Repair

Whether you have a pinhole leak or widespread membrane damage, our repair team has the experience to diagnose the root cause and fix it properly,not just cover it up. We work with all major flat roofing materials and tailor our repair approach to what your specific system requires.

Scheduled Roof Maintenance

A well-maintained flat roof can outlast its expected lifespan by years. Our maintenance programs are designed to catch small vulnerabilities before they become expensive failures,cleaning drainage systems, sealing developing cracks, reinforcing flashings, and documenting roof condition over time.

Full Roof Replacement

When a roof is too far gone for repairs to make sense, a full replacement is the most cost-effective long-term solution. We manage the entire process,from removing the old system and inspecting the deck to installing a new high-performance membrane with all flashings, edging, and drainage properly addressed.

New Roof Installation

Building new or adding a structure? We install flat roofing systems that meet Long Island’s climate demands, with proper drainage design, insulation layering, and membrane selection tailored to your property type and usage.

Emergency Roofing Services

Severe weather doesn’t wait for business hours, and neither do we. When a storm causes sudden damage to your flat roof, our emergency team responds quickly to stabilize the situation, prevent water intrusion, and get your property secured while permanent repairs are planned.

Serving Both Homeowners and Businesses

Flat roofing needs vary significantly between residential and commercial properties. We have deep experience with both and tailor our approach accordingly.

Residential Roofing Solutions

For homeowners, the priority is a leak-proof, energy-efficient roof that protects the family and holds up through Long Island’s winters and humid summers. We install systems designed for minimal maintenance and maximum durability,backed by warranties that give you real peace of mind.

Commercial Roofing Services

Commercial roofs face heavier demands,larger surface areas, rooftop equipment, and the need to minimize business disruption during installation. We coordinate closely with property managers and business owners to complete projects efficiently without compromising the quality of the finished system.

How We Install a Flat Roof, Step by Step

Every flat roof we install follows a structured, proven process from the moment we arrive to the final handover.

Phase 1

Detailed Site Evaluation

Residential

We start by thoroughly examining your existing roof, checking for moisture trapped in the deck, soft spots, blocked drains, and any structural issues. The old surface is then stripped and cleaned to create a solid, even base.

Commercial

Large commercial roofs require extra planning. We evaluate insulation condition, drainage layout, and load-bearing capacity. Coordination with property managers ensures minimal interference with operations.

Phase 2

Insulation Installation

Residential

ISO insulation boards are mechanically fastened using brackets and screws. This layer improves thermal performance, helps regulate interior temperatures, and gives the membrane a stable surface to bond to.

Commercial

On commercial properties, heavy-duty insulation fasteners are used to prevent shifting under wind uplift. Consistent coverage is critical for both energy performance and structural integrity.

Phase 3

Membrane Application

Residential

We apply two layers of base coat followed by a cap sheet. This three-layer system provides excellent waterproofing and resistance to UV exposure. Each layer is applied with care to ensure no weak points.

Commercial

The same multi-layer approach is used with additional attention to seam placement. This system is built to withstand heavy foot traffic, equipment vibration, and thermal expansion on large surfaces.

Phase 4

Final Sealing & Walkthrough

Residential

All seams, perimeter edges, and flashing transitions are sealed and inspected. We verify that drainage is functioning correctly and meet our quality standards before the job is complete.

Commercial

Includes reinforced seam sealing, full flashing inspection, and a drainage flow test. We document the system and walk the property manager through everything before closing the project.

The Materials We Trust

The quality of a flat roofing system is only as good as the materials used to build it. We work exclusively with proven products from manufacturers who stand behind their performance.

Residential GAF Liberty SBS
Residential

GAF Liberty SBS

GAF Liberty is a self-adhering modified bitumen membrane that delivers superior waterproof performance without requiring open-flame torching during installation. It’s durable, flexible through temperature extremes, and designed for long-term service life on residential flat and low-slope roofs.

Commercial Carlisle TPO & EPDM
Commercial

Carlisle TPO & EPDM
