Commercial Roofing in Paterson, NJ

What Commercial Roofing Involves for Paterson Properties

Commercial roofing is fundamentally different from residential sloped roofs. Most commercial buildings in Paterson use flat or low-slope designs that require continuous waterproof membranes rather than shingles. Our crews strip old roofing down to the structural deck, repair any rot or corrosion, install new insulation and cover board, then apply a single-ply membrane—typically Firestone UltraPly TPO 60-mil or Carlisle Sure-Seal EPDM 45-mil. For buildings needing extra puncture resistance, we install GAF Liberty SBS modified bitumen.

Materials and Methods We Use

We carry three primary membrane systems. TPO (thermoplastic polyolefin) is heat-welded at seams—good for reflecting UV rays and reducing cooling costs. EPDM (ethylene propylene diene monomer) is a synthetic rubber sheet adhered or ballasted, known for flexibility in Paterson’s freeze-thaw cycles. Modified bitumen (SBS) is torch-applied or self-adhering, giving you a built-up, multi-layer barrier ideal for high-traffic roofs. Each system includes edge metal, flashings at parapet walls, and proper drainage scuppers.

Cost Ranges for Paterson Commercial Roofs

Expect $5.50–$9.00 per square foot for TPO, $6.00–$9.50 for EPDM, and $7.00–$10.50 for modified bitumen. A 2,500-square-foot flat roof runs $13,750–$26,250 installed. Costs include deck prep, insulation, membrane, flashings, and labor. Permits and structural load calculations add $500–$1,200 depending on building size.

Signs You Need Commercial Roofing

Paterson’s climate—heavy snowfall, rain, and humidity—accelerates wear. Look for ponding water from flat roof membrane fatigue, which leads to leaks. Thermal cycling splits modified bitumen seams as temperatures swing from below freezing to 90°F. Ice dam damage at parapet wall flashings forces water under the membrane. UV degradation of single-ply EPDM seams causes cracking after 8–12 years. If you see water stains on ceiling tiles, blistering or bubbling membrane surface, standing water 48 hours after rain, or cracked or curled flashing at edges, call us for an inspection.

Step-by-Step Commercial Roofing Process

1. Inspection and Load Analysis—We measure your roof, check deck condition, and calculate structural load for added insulation layers. NJ UCC permit required for reroofing over 25% area.
2. Material Selection—We help you choose TPO, EPDM, or modified bitumen based on budget, traffic, and energy goals.
3. Strip and Prep—We remove all old membrane, repair damaged decking, and install tapered insulation for positive drainage.
4. Membrane Installation—Our crew heat-welds TPO seams, adheres EPDM with bonding adhesive, or torches modified bitumen. All flashings at parapets and penetrations get reinforced.
5. Final Inspection and Warranty—We flood-test for leaks, provide manufacturer warranty (15–25 years), and give you a maintenance schedule.

Insurance, Permits, and Safety

We carry $2 million general liability and workers’ comp. Every job includes an OSHA fall protection plan mandatory for all flat roofs. Snow loads require reinforced deck design in Paterson; we engineer for 30 psf minimum. Freeze-thaw cycles crack unsealed laps, so we use sealant on every lap joint. High humidity accelerates mold under membrane, so we install vapor barriers where needed. We handle all NJ UCC permits.
