Commercial roofing covers the flat and low-slope assemblies on garden apartments, retail strips, warehouses, and office parks. Most buildings we open up sit under a single-ply membrane, either TPO or EPDM, over a modified bitumen or built-up roof.
We're a licensed and insured South Brunswick roofing contractor, and every job starts with a roof asset survey.
We walk the rooftop, probe the roof deck for soft spots, check parapet flashing, and core a sample so we know the substrate under the old felt and tar.
Cost comes down to square footage, whether we tear off or recover over the existing assembly, and how much insulation must be replaced to meet building code. Scuppers, curbs, and vents each need their own flashing detail, priced as its own line.
Structural work shows up more often than owners expect. We sister a rafter or truss chord, replace a rotted ridge beam or ceiling joist, and add purlin, batten, and counterbatten framing before a metal panel goes back down.
Under the new membrane we lay a vapor barrier and synthetic underlayment, replacing the old roofing felt and tar paper. An ice-and-water shield goes at the eave and any valley.
South Brunswick summers are hot and humid with frequent thunderstorms, and Nor'easters drive rain sideways into open laps. Scaffold goes up where the edge needs work, and each crew member stays tied off in a safety harness.
What's Included
Our Commercial Roofing Process
What a Commercial Roof Replacement Looks Like, Step by Step
- First we run a roof asset survey: mapping drains and scuppers, checking the roof deck for soft spots, and noting every penetration that needs new flashing.
- Second, we core the assembly so we know the substrate and the insulation type under the old felt, tar, and gravel surfacing.
- Third, you get a line-item roof estimate that separates tear-off, deck repair, insulation, membrane, and flashing instead of bundling them into one number.
- Fourth, we stage materials at the access point, ladder or interior stair, and set the dumpster where it blocks the fewest parking spots. The truck carries a nail gun, air compressor, pry bar, and roofing shovel.
- Fifth, the roof deck is checked board by board, and any plywood or OSB sheathing with rot or delamination is replaced before we go further.
- Sixth, new insulation goes down and the membrane is rolled, welded, or adhered in staggered courses so the laps never line up.
- Seventh, flashing is finished at the parapet, scuppers, pipe boots, and counter-flashing, then we flood-test the drains and clear the debris.
- Last, we walk the rooftop with you and hand over photographs, the completed scope, and the warranty paperwork.

Signs You Need Commercial Roofing
Warning Signs Your Commercial Roof Needs Attention
- Ponding water that sits more than 48 hours after a storm means the roof deck has settled and no longer drains to the scupper.
- Blistered or wrinkled membrane where summer heat has cooked the adhesive and the laps have started to peel and lift.
- Interior ceiling tile stains that show up after Nor'easters, which is usually how a tenant complaint reaches the property manager first.
- Granule loss and bare spots on modified bitumen where UV degradation has eroded the surface down toward the bitumen.
- Paint flaking off metal panel ribs and backed-out screws, a sign the fastener has lost its sealant washer and wind uplift is working the panel.
- Ice dam buildup along a parapet or in a valley after heavy snow, which wicks meltwater back under the flashing; steam ice removal beats chipping with a hammer.
- Soft spots underfoot on the rooftop, which point to saturated insulation and a roof deck that has started to rot and decay.
- Rotted fascia, a sagging rake board, or a loose coping stone on the parapet cap, all of which let water into the wall cavity.
Commercial Roofing — Frequently Asked Questions
How much does commercial roofing cost in South Brunswick?
Commercial roofing costs come down to square footage, membrane choice, and whether we tear off or recover the existing assembly.
Insulation, building code upgrades, and the number of scuppers, curbs, and vents all move the price. A reflective roof coating can stretch a sound membrane when the laps still hold.
How long does a commercial roof replacement take?
Most low-slope replacements run three to seven working days on a building under 10,000 square feet. Deck repairs and rain are the two things that stretch that window.
Winter work slows again because ice dam removal and torch work both need dry, safe conditions.
Do you install anything besides flat membrane roofs?
Yes. We also service mansard and gambrel faces, hip and gable ends, dormers, and the canopy or awning over a storefront entry, plus the skylight curbs and overhang trim above them.
Those sections get a starter course at the eave, field course shingles set with ring-shank nails, and a new ridge cap and rake verge at the top.
We also install architectural shingle, three-tab shingle, asphalt shingle, cedar shake, wood shake, slate, clay tile, concrete tile, corrugated panel, and standing-seam panel above a 4:12 pitch, with snow guards and a rated anchor for the safety harness.
Does insurance cover storm damage on a commercial roof?
Storm damage is worth documenting the same week it happens. We photograph the hail bruising, measure the affected area, and write a scope you can hand to your adjuster as insurance claim assistance.
Before we file anything, we confirm the waterproofing under the damaged section is sound, because carriers will not pay for weatherproofing that was already failing.
Can your crew work around our tenants and business hours?
Yes. We stage the tear-off in sections, keep the dumpster out of the drive lane, and schedule the loudest work around your tenant hours.
On occupied buildings we seal the roof each evening so nobody works under an open deck overnight.
What warranty comes with a new commercial roof?
TPO and EPDM membrane systems carry manufacturer warranties in the 15 to 30 year range, and our own workmanship agreement runs alongside that.
We put the terms in writing before the first pallet comes off the truck, and we tell you plainly what the warranty does not cover.
Don't just take our word for it — hear from our satisfied customers.
"Our Kendall Park strip center had leaked over the same tenant space for two winters. They cored the roof, showed us the wet insulation, and handed us a line-item estimate before we signed anything." — Dana R., Kendall Park
"The Monmouth Junction warehouse needed a recover, and they staged the work around our dock schedule so shipping never stopped. The TPO membrane was down and welded in four days." — Miguel S., Monmouth Junction
"Ice dam water was running down the inside of our Dayton office wall every February. They replaced the parapet flashing and counter-flashing, and the wall has stayed dry through two winters." — Karen P., Dayton
