We've built our reputation one roof at a time—through honest assessments, meticulous installations, and the kind of follow-through that turns first-time clients into lifelong advocates. Property managers call us because we show up when we say we will. Building owners trust us because we stand behind every seam.
There's a reason property managers across the tri-state area keep our number on speed dial. When a roof fails, everything underneath is at risk—inventory, equipment, operations, tenants. We understand what's at stake, and we treat every project like our own building is on the line.
As a GAF Master Elite® contractor—a distinction earned by just 2% of roofers nationwide—we've proven our commitment to installation excellence year after year. Whether you need a high-reflectivity TPO system for your warehouse, a time-tested EPDM rubber membrane for your apartment complex, chemical-resistant PVC roofing for your restaurant, or custom-fabricated standing seam metal for your architectural project, we bring the same level of precision to every job.
Why Property Managers & Building Owners Choose Genc Construction
Managing commercial real estate in the Northeast isn't for the faint of heart. Between freeze-thaw cycles that stress every seam, summer heat that can blister inferior membranes, and the occasional nor'easter that tests every penetration, your roof takes a beating that property owners in milder climates simply don't understand. We do—because we've been solving these exact problems across Bergen County, Manhattan, Brooklyn, and throughout New Jersey since 1993.
What really sets us apart is our in-house fabrication facility in Pennsylvania. Instead of ordering standard parts and hoping they fit, we manufacture custom flashings, edge metals, and architectural components to your building's exact specifications. The result? Cleaner installations, fewer callbacks, and a finished product that looks like it belongs there—because it was made specifically for your building.
Zero Business Disruption
Your tenants don't stop paying rent because we're on the roof. We phase our work, control dust and debris, and communicate proactively so your building stays fully operational.
NDL Warranty Coverage
No Dollar Limit warranties from GAF, Firestone, and Carlisle mean your investment is protected without caps or fine-print exclusions. If something fails, it gets fixed—period.
Transparent Pricing
We walk you through every line item before you sign anything. No change orders that magically appear mid-project. The price we quote is the price you pay.
Emergency Response
Leaks don't wait for business hours, and neither do we. Our emergency crews respond within hours—not days—because we know what water damage costs you every minute.
Commercial & Industrial Roofing Solutions
Every building type presents its own challenges. A restaurant's grease vents demand different solutions than a warehouse's HVAC penetrations. A historic brownstone requires a different touch than a modern distribution center. Here's how we approach the industries we serve:
Warehouses & Distribution Centers
Your 24/7 logistics operation can't afford downtime. We install TPO and EPDM systems in phases, working around your shipping schedules, and engineer proper drainage for roofs that often span the size of football fields.
Multi-Family Residential
Tenant complaints about roof work are the last thing a property manager needs. We communicate directly with building management, contain debris meticulously, and complete work efficiently to keep residents happy.
Retail & Shopping Centers
When you have a dozen tenants and twice as many HVAC units, penetration flashing becomes an art form. We've roofed shopping centers with complex layouts that would make other contractors walk away.
Restaurants & Food Service
Kitchen exhaust vents destroy ordinary roofing materials within years. We exclusively install PVC membranes around grease hoods—the only material engineered to withstand animal fats and cooking oils indefinitely.
Office Buildings
Class A office space commands Class A roofing. We install energy-efficient systems that reduce operating costs, properly flash every rooftop unit, and leave the finished product looking as sharp as the building itself.
Industrial Facilities
Chemical plants, cold storage, and manufacturing environments throw curveballs that suburban roofers have never seen. Between extreme temperature differentials and corrosive atmospheres, we know which systems survive—and which fail.
Let's talk about what your building actually needs—no sales pitch, just straight answers.

Our crews work out of Cliffside Park daily, reaching most of the metro area within an hour. And because we manufacture our own metal components in Pennsylvania, we don't wait on suppliers—we control our own timelines.
