Try "ice dam", "financing", "Montclair", "flat roof coating" or "Colombia".
Warehouses, factories, distribution centers, pharmaceutical plants, hospitals and emergency-response buildings. Restoration, repair, replacement and maintenance of flat and low-slope roofs from 10,000 to 100,000+ square feet, with the logistics handled so production never stops.
When roofers hear the size of the job they say "yes, we can do that". We have done it: 100,000-square-foot roofs, hospitals, pharmaceutical plants and emergency-response buildings, with the schedule, the codes, the warranties and the maintenance that follow.
A selection from our commercial, industrial, institutional, government, religious and multi-family work across North Jersey, as printed in our 2026 county flyers.
Flat roof repairs, restoration coatings and replacements; roof drains, gutters, vents, skylights and bulkheads; facade restoration, pointing, waterproofing and painting; windows and entry doors. On a commercial building these are one system, and we treat them as one job.
Explore the interactive building →Repairs and coatings are not where most roofers make their money, so they sell replacements. We track the numbers: more than four out of five commercial roofs we inspect are restored for 60 to 70% less than a tear-off, and replaced only when the deck or the insulation says so.
For: an aging EPDM, TPO, PVC, modified bitumen or metal roof with a sound deck.
What: clean, repair, triple-ply reinforce every seam and penetration, then a seamless silicone or acrylic system.
60–70% less than replacement · 20–50 yr warrantyFor: every roof that has to keep a warranty valid and a plant running.
What: penetrations, flashings, drains, sealants and coatings checked and fixed on a schedule; written report with photos.
Plans from annual to quarterlyFor: wet insulation, a failed deck, or a roof patched for too many years.
What: tear-off, tapered insulation, new membrane and details to the manufacturer's spec, full-system warranty.
Warranties up to 30–40 yrFor: a leak over stock, a storm, a collapse, an insurance claim.
What: a live person answers, a crew mobilizes to the size of the problem, the roof is made watertight, then a permanent fix.
A real roofer on the phone, 2 a.m. or ChristmasFor: capital planning, acquisitions, a second opinion on a replacement quote.
What: infrared moisture scan, registered drone survey, core samples, written condition report.
A free second opinion before you replaceFor: leaks that are not the roof's fault: parapets, masonry, stucco, windows, joints.
What: tuck pointing, exterior waterproofing, facade repair, caulking and painting by the same company.
One contractor for the whole exterior
Elite Partners, an automotive-accessory distributor in Whippany, wanted solar panels on its 30,000-square-foot roof and had been quoted $300,000 for the roof replacement that supposedly had to come first. We installed a silicone restoration system with a 20-year warranty instead. The roof was solar-ready, like new, and $168,000 cheaper: 56% off the quote.
Any snag in your production costs more than the roof. A big job is won or lost in the planning: the phasing map, the staging area, the crane window, who gets a call when the weather turns.
Owner-led inspection, infrared moisture scan, core cuts and a drone survey. You get a phasing map, a materials list and a schedule before anyone signs.
Material hoists and cranes booked around your truck traffic, staging kept clear of loading docks and fire lanes, deliveries timed to the phase in progress.
Site-specific safety plan, fall protection and perimeter warning lines, and insurance sized to the project, including jobs that run into the millions.
Restoration means no tear-off, so the roof stays closed and the noise stays low. When a shift cannot be disturbed at all, we work around it: off-hours, weekends, holidays.
A foreman on the roof, a supervisor on site, video quality calls every two hours, before-and-after photos of every section, a daily report to your facilities manager.
Manufacturer inspection and warranty registration, as-built notes, a maintenance plan that keeps the warranty valid, and the owners' direct line on every document.
96% of our projects finish on time and on budget. The other 4% are concealed structural issues, and you hear about them the day we find them, not at the invoice.
Request Commercial Advice →Off-label coatings are where a cheap restoration fails a year later. We install Karnak, GE and Tri-Built silicone and acrylic systems over existing membranes, and Mule-Hide, GAF, Johns Manville, Elevate and Versico systems when the roof is replaced, certified by each so the warranty is theirs, not just ours.
Not a slogan: a binding commitment. Bring a written proposal for the same product, system, warranty and service agreement from a licensed and insured contractor, and we beat it. Then we do four things most crews do not:
And a share of this roof funds a roof for a family in need, through our One4One program.

The owner inspects the roof in person. Infrared scan, drone survey and core cuts where the roof calls for them. A written condition report with photos, whether or not you hire us.
Restore, repair or replace, with the system, the warranty, the phasing plan and the price in writing. No sales pressure, no commission-driven upsell. Bring any other written estimate: we beat it.
Certified crew under a dedicated foreman, sections closed watertight every evening, video checks every two hours, a photo report to your facilities manager every day.
Manufacturer inspection and warranty registration, closeout photos and as-builts, and a maintenance plan with scheduled visits so the warranty stays valid for its whole term.
Roof size, the number of penetrations, wet insulation, access and the system decide the price. These are honest ranges from our own jobs so you can budget; the written proposal after the survey is exact.
We write phased scopes that fit a capital plan, bill by progress, and give your accountant what they need: a restoration can often be expensed in the year it is done, a replacement depreciated as a capital improvement. Ask your tax advisor; we provide the documentation either way.
Financing and payment options →Storm damage? We document the roof for your insurer and meet the adjuster on the roof.

A roof is a system, not just a membrane, so it takes an inspection: age, condition, how much of the insulation is wet, how the drains and details were built. Our owner inspects commercial roofs personally, with an infrared scan where it matters, and puts the recommendation in writing. Four out of five roofs we are asked to replace do not need it.
One hundred thousand square feet and up; we have done it. High-stakes buildings too: hospitals, emergency-response facilities, pharmaceutical plants. The crew, the insurance and the logistics are sized to the project, including jobs that run into the millions.
A restoration needs no tear-off, so the roof stays closed, the noise stays low and the thousands of pounds of old roofing never come down through your building. Work is phased around your shifts and deliveries, and when a shift cannot be disturbed at all we work nights, weekends or holidays.
Bring a written proposal from another licensed and insured contractor for the same product, system type, warranty length and service agreement, and we beat it. It has to be a like-for-like comparison; a thinner coating or a shorter warranty is not the same roof.
We give a timeline after we have seen the roof: size, penetrations and weather decide it. Larger commercial roofs typically run two to three weeks in phases. We finish on time and on budget 96% of the time, and you hear about the exceptions the day they are found.
Restoration systems carry manufacturer warranties of 20 to 50 years depending on the package. Full replacements carry 15- to 40-year material warranties and up to 20 years of workmanship warranty depending on the package. Emergency repairs carry a 1-year workmanship warranty. Your proposal states the manufacturer and the workmanship warranty separately.
Yes: licensed and insured as a roofer in New Jersey, with additional coverage for projects that cost into the millions. If a permit is needed we obtain it and you reimburse the fee.
All of New Jersey for commercial and industrial work. Depending on size and scope, also Pennsylvania, Connecticut, Delaware, Maryland and Massachusetts.
Licensed and insured to the value of the project first. Then a track record with roofs like yours, at least twenty years in business, clear answers on scope, cost and timeline, and references you can call. If any of that is evasive, keep looking.
