What Does Commercial Roofing Involve?
Commercial roofing works differently than residential. Your building likely has a low-slope or flat roof deck, which means water doesn't shed quickly. It sits and pools until the membrane and drainage handle it. A proper commercial roofing system uses a continuous membrane—TPO, EPDM, modified bitumen, or PVC single-ply—to keep water out. TPO is a reflective white membrane that cuts cooling costs. EPDM is a black rubber sheet that handles extreme weather. Modified bitumen is an asphalt-based membrane applied in layers, often with a torch or adhesive. Built-up roofing (BUR) alternates layers of felt and asphalt for a heavy, time-tested system.
When we assess your roof, we start with a roof asset survey. We check the insulation for moisture, the parapet for cracks, and the flashing around penetrations. That survey tells us whether to repair, recover, or tear off. A recover adds a new membrane over the old one if the substrate is sound. A tear-off strips everything down to the roof deck and rebuilds from there. For a low-slope roof, we typically recommend TPO or EPDM because they handle ponding water and thermal movement well. We also verify local building code requirements for drainage and fire ratings.
How Much Does Commercial Roofing Cost in Newark?
Commercial roofing costs depend on the system you choose, the size of your roof, and the condition of the deck. In Newark, expect to pay between $8 and $15 per square foot for a TPO or EPDM membrane installed, including insulation and flashing. A modified bitumen system runs slightly higher, $10 to $18 per square foot, due to the extra layers. Built-up roofing sits in a similar range. Metal panel roofing, like standing-seam panels, costs more upfront—$15 to $25 per square foot—but lasts 40 years or more with minimal maintenance.
Warranty terms matter. Most TPO and EPDM systems come with a 15- to 30-year NDL (no-dollar-limit) warranty from manufacturers like Carlisle SynTec, GAF EverGuard, Firestone, Johns Manville, or Versico. That warranty covers material defects and, with a certified installer, labor too. We always walk you through the warranty before we start. A roof is a 20-year decision. You want to know what's covered and what isn't.
Tenant coordination is part of the job. If you're roofing an occupied building, we schedule the tear-off and membrane installation to minimize disruption. We set up scaffold and safety harness systems for our crew, but we also keep your entrances clear and your tenants informed. That's the practical side of commercial roofing that many contractors skip.
When Do You Need Commercial Roof Repair or Replacement?
Commercial roofing fails slowly. Water seeps through a tiny puncture in the membrane, wicks along the insulation, and erodes the roof deck before you see a leak inside. By the time you notice a stain on the ceiling, the damage has spread. Look for these signs: ponding water that doesn't drain within 48 hours, granule loss on modified bitumen, blistering or delamination on TPO, and cracks or splits at the parapet. If the membrane is end-of-life wear—say, 20 years old with widespread cracking—replacement is more cost-effective than repeated repairs.
Storm damage is another trigger. Newark's nor'easters bring intense wind and ice that can lift membrane edges and puncture EPDM with debris. After a big storm, we inspect for punctures, tears, and loose flashing. We also handle insurance claims, from the adjuster inspection to the proof of loss form. If you're filing a claim, call us first. We'll document the damage so you get the full scope covered.
Regular maintenance extends a commercial roof's life significantly. We recommend a twice-yearly inspection—spring and fall—to clear debris, reseal flashing, and recoat worn areas. A coating system, like a silicone or acrylic coating, can add 10 years to an aging TPO or metal roof by reflecting UV rays and sealing micro-cracks. That's a fraction of replacement cost.
How Do We Install a Commercial Roof?
Our process is methodical. First, we protect the building: scaffold, safety harnesses, and drop cloths. Then we tear off the old membrane and insulation, down to the roof deck. We inspect the deck for rot, decay, and sag. We replace any damaged sections. Next, we lay new insulation board, tapered if needed to improve drainage. Then we install the membrane—TPO is heat-welded at the seams; EPDM is adhered with contact adhesive; modified bitumen is torched or mopped. We use ring-shank nails for the insulation, self-adhered flashing at the parapet, and a starter course at all edges. Field courses overlap and stagger so water runs off, not in. Finally, we inspect every seam and penetration. We do a flood test or electronic leak detection to confirm the membrane is watertight before we leave.

Frequently Asked Questions
How long does a commercial roof last?
Commercial roofing lasts 15 to 30 years depending on the material. TPO and EPDM typically last 20 years, modified bitumen 20 to 25, and metal panels 40 or more. Regular maintenance extends that lifespan.
Can you repair a commercial roof instead of replacing it?
Commercial roofing repair is possible if the damage is localized—a puncture, a loose seam, a flashing gap. If the membrane is widespread cracking or the insulation is wet, replacement is more cost-effective. We'll tell you honestly which makes sense.
Do you help with insurance claims for commercial roofs?
Yes. Commercial roofing storm damage is common in Newark. We document the damage, meet the adjuster, and provide a detailed scope. We help with the supplemental claim if the initial settlement is too low.
