⭐ Trusted by Bergen County Business Owners
"GenSun had such an easy process. They were completely transparent and provided an easy online meeting and got the price for all 3 options right up front before they even saw the roof… then they came to inspect and actually lowered the original price. Very honest people and the job they did was terrific."— Mr. Gould, Warehouse Owner
"My property manager was blown away by their process. Great people, very educated about flat roofs, provided us options. We ended up doing the full replacement and their pricing was 25% less than 3 other guys! Thanks to Coach Jim and his team."— Pastor John, Catholic Church
"Truly a no-brainer. GenSun made it so easy from the start — pricing up front in a Zoom meeting, then inspected to confirm. The low price was a huge incentive as well."— Jeremy, Commercial Industrial Building

🟢 Roof Coating — Protect & Extend
A commercial roof coating is a seamless, fully-adhered liquid membrane applied directly over your existing flat roof. It seals cracks, stops leaks, reflects UV rays, and extends roof life — all without the expense and disruption of tear-off or re-installation.
Best For:
- ✓Roofs in fair to good condition
- ✓Roofs under 15–18 years old
- ✓Sound deck and dry insulation
- ✓Minor cracks, seam failures, or UV degradation
- ✓Budget-conscious Bergen County property owners
Types of Coatings:
- ✓Silicone — Best for ponding water, 10–20 yr lifespan
- ✓Rubber (EPDM) — Durable, handles NJ temperature swings
- ✓Spray Foam (SPF) — Insulates & waterproofs simultaneously
🟡 Roof Re-Cover — Renew Without Full Tear-Off
A roof re-cover involves installing a brand new roofing membrane over the top of the existing system — without removing the old one. It delivers a fresh, warrantied roof at significantly less cost than a full tear-off replacement.
Best For:
- ✓Roofs with failed membrane but dry insulation
- ✓Buildings where a second layer is permitted by code
- ✓Property owners wanting a warrantied new roof without full cost
- ✓Situations where minimal business disruption is critical
Important Notes:
- ⚠Codes typically allow only ONE re-cover before full replacement
- ⚠Any wet insulation must be removed before overlay
- ⚠Adds slight weight load — structural review may be needed
- ✓GenSun performs moisture scanning before recommending
- ✓Saves 30–50% vs. full replacement
- ✓New 20–25 year manufacturer warranty included
🔴 Full Roof Replacement — The Complete Solution
When a flat roof has reached the end of its serviceable life — with structural damage, saturated insulation, deck deterioration, or widespread failure — a full replacement is the only lasting solution. GenSun installs a brand new high-performance roof system built to last 25–30 years.
Best For:
- ✓Roofs over 20–25 years old
- ✓Widespread structural damage or rot
- ✓Saturated or compressed insulation
- ✓Roofs that have already been re-covered once
- ✓Multiple active leaks throughout the system
Systems We Install:
- ✓TPO — Reflective, heat-welded, 20–30 yr lifespan
- ✓EPDM — Rubber membrane, ideal for NJ winters
- ✓Modified Bitumen — Multi-ply, extreme durability

Why Bergen County Business Owners Trust GenSun
Bergen County is the most densely populated county in New Jersey and one of the most commercially active in the entire Northeast. With over 900,000 residents and a commercial landscape that stretches from the massive retail corridors of Paramus along Route 17 and Route 4 to the high-rise office parks of Fort Lee and the industrial districts of Garfield and Lodi, Bergen County is home to thousands of commercial buildings — the vast majority of which have flat roofs that face the same relentless challenge: New Jersey weather.
Bergen County flat roofs deal with the full spectrum of Northeast climate stress. Summer brings intense UV exposure, heat expansion, and heavy rainstorms that push standing water into every crack and seam. Winter delivers freeze-thaw cycles that open those cracks wider with every passing season. Many of Bergen County’s commercial buildings date from the 1960s through 1990s — meaning their flat roofing systems are at or well past their expected service life. A leak that starts small in a Hackensack office building or a Teaneck church can quietly destroy decking, insulation, and interior finishes before anyone notices.
GenSun Commercial Roofing is Rutherford-based — meaning Bergen County is our home market. We’ve worked with property owners, property managers, and church administrators across the county for over 35 years. We know the building stock, the local contractors, and the permit processes in Bergen County municipalities. And we bring that local knowledge to every project — whether it’s a coating on a Paramus strip mall, a re-cover on a Teaneck warehouse, or a full replacement on an Englewood church.
Our process is built around transparency. We start with a free 20-minute Zoom meeting where we review aerial photos and satellite measurements of your roof, walk through all three pricing options, and give you real numbers before we ever set foot on your property. No surprises. No pressure. This approach has earned us a 5-star Google rating and a steady stream of referrals from Bergen County property owners who appreciated our honesty and came back for their next building.
Whether you manage a retail plaza in Paramus, a warehouse in Garfield, a church in Ridgewood, an office complex in Hackensack, or an industrial building in Lodi — GenSun has the local experience, certified crews, and straightforward pricing to handle it right the first time. Call or text us today to schedule your free 20-minute estimate.
