A commercial roof has a different job than a house roof: it protects inventory, equipment, tenants, and revenue, and every hour it leaks is an hour the business loses. Commercial and flat roofs also fail differently — at seams, flashings, drains, and parapets — so they need a contractor who lives in membrane systems, not just shingles.

The systems we install

Most commercial roofs in New Jersey are single-ply membrane or modified bitumen, and we install all the major types so the recommendation fits the building instead of whatever one product we happen to sell.

  • TPO — white, heat-reflective, heat-welded seams. Lower summer cooling load and the strongest watertight seam available. The default for most new commercial flat roofs.
  • EPDM — the classic black rubber roof. Proven longevity, fast to install, seams are taped or seam-welded. Still the right call on plenty of buildings.
  • Modified bitumen — torch- or cold-applied multi-ply asphalt. Tough, walkable, and good for roofs with heavy foot traffic or rooftop equipment.
  • Restoration coatings — silicone or acrylic systems that can extend a sound but aging roof's life for years at a fraction of tear-off cost.

Repair, recover, or replace

Not every aging commercial roof needs a tear-off. If the membrane is sound and the deck is dry, a restoration coating or a recover system can add years for far less money and far less disruption. If the roof is saturated or failing systemically, a tear-off is the honest answer.

We do a moisture survey before recommending anything, because recovering a wet roof just seals the problem inside. You get the real condition in writing, and the option that actually makes sense for the building.

Fixing the real problem: drainage

Most commercial roof failures trace back to water that sits instead of draining. Ponding accelerates membrane breakdown, overloads the structure, and finds every weak seam. Where ponding is the issue, we add tapered insulation to build positive slope to the drains — fixing the cause, not just patching the symptom.

Built for minimal disruption

We plan commercial work around your operations — staging, material lifts, and tie-ins sequenced so occupied space stays dry and accessible, and so a retail floor or office never has to close because of the roof. For property managers juggling multiple buildings, we also run maintenance programs that catch small issues on a schedule instead of in an emergency.

When You Actually Need This

  • Active leaks over occupied commercial space
  • An aging built-up or single-ply roof past its service life
  • Ponding water that won't drain after rain
  • A property you're buying or selling that needs a roof condition report
  • A multi-family or mixed-use building with recurring tenant leaks
Our Process

How We Handle Commercial & Flat Roofing

  1. 1

    Roof survey & moisture check

    We walk the roof, document conditions and drainage, and check for trapped moisture in the existing system — then put it in a written report with photos.

  2. 2

    System recommendation

    Repair, recover, restoration coating, or full tear-off — we recommend the option that fits the roof's real condition and your budget, not the biggest invoice.

  3. 3

    Install with minimal disruption

    We sequence the work to keep your business running — staging, deliveries, and tie-ins planned so occupied space stays dry and accessible.

  4. 4

    Warranty & maintenance plan

    Manufacturer system warranty registered, plus an optional maintenance program so small issues get caught before they become tenant complaints.

Frequently Asked Questions

For most NJ commercial buildings we recommend TPO — heat-welded seams are the strongest watertight bond available and the white surface cuts summer cooling cost. EPDM and modified bitumen are still the right choice on specific buildings; we match the system to the roof, not the other way around.
