Flat Roofs That Handle Water and Foot Traffic

Installation and repair of commercial flat roofing systems in New Jersey.

Flat roofs on commercial buildings need to shed water through drains and scuppers while supporting HVAC units and occasional foot traffic for maintenance. In Edison and surrounding areas, where heavy rain can overwhelm blocked drains and cause pooling, a properly installed membrane and drainage system prevents leaks and extends the roof's lifespan. You need a roof that handles the demands of daily operations without constant repairs.


Pmc Exteriors LLC installs and repairs flat roofing systems designed for commercial properties, including membrane options suited for maintenance-sensitive buildings. The work includes leak detection, drainage correction, and repairs that address problems before they force a full replacement. Every project minimizes disruption to business operations and uses materials chosen for durability and weather resistance.

What Happens During Flat Roof Installation

The crew inspects the existing surface and drainage system, checking for low spots where water collects and membrane sections that have cracked or separated. In Edison and surrounding areas, where temperature swings cause expansion and contraction, seams and flashings often fail before the main membrane does. You see a clear plan for addressing weak points and improving water flow.


After installation or repair, water drains completely without standing in pools, and the roof supports equipment and foot traffic without tearing or puncturing. Interior ceilings stay dry during storms, and you stop dealing with emergency calls about water in the building. The membrane forms a continuous barrier that resists UV damage and weathering.


The work includes coordination with building managers to schedule around tenant hours and maintain access to loading areas. Ongoing maintenance support is available to catch small problems before they require major repairs, and the crew provides documentation showing what was installed and when. The project timeline accounts for weather delays and keeps the building weather-tight throughout the process.

What to Know Before Scheduling Work

Commercial roofing projects involve coordination and planning that differ from residential work. These answers address the questions property managers and owners typically ask during initial consultations.

How long does a commercial flat roof installation take?

Small buildings finish in a few days, while larger properties take one to two weeks depending on square footage and membrane type. The crew schedules work to avoid peak business hours when possible.

What causes leaks in flat roofs?

Blocked drains cause water to pool and find gaps, and seams separate as the membrane ages. Foot traffic around HVAC units can puncture the surface if walk pads are not installed.

How do you detect leaks without visible water damage?

The crew uses moisture meters and visual inspections to find wet insulation and membrane defects before they cause ceiling stains. Early detection prevents interior damage and mold growth.

What membrane options work best for commercial buildings?

TPO and EPDM membranes handle weather exposure and UV radiation well. The choice depends on building use, budget, and maintenance access requirements.

How often does a flat roof need maintenance?

Annual inspections catch debris in drains and small membrane issues before they worsen. Buildings with heavy HVAC use or frequent roof access benefit from twice-yearly checks.
