What Is Commercial Roofing?
Commercial roofing is the predominantly low-slope membrane and metal roof systems that protect offices, warehouses, retail, and industrial buildings. Per NRCA, these low-slope assemblies need positive drainage because standing water accelerates membrane aging.
What Commercial Roofing Services Does Newark Quality Roofing Provide?
Newark Quality Roofing provides commercial roof installation, repair, replacement, thermal-imaging inspection, and infrared leak detection across Newark and Essex County, New Jersey. The company is a registered New Jersey Home Improvement Contractor that carries liability insurance.
Commercial roof installation and replacement cover new construction and tear-off-to-deck reroofs on flat and low-slope buildings. Under the Uniform Construction Code, commercial and multi-family reroofs follow N.J.A.C. 5:23 and require a construction permit, unlike the ordinary-maintenance carve-out for detached one- and two-family homes.
Commercial roof repair addresses membrane punctures, open seams, flashing failures, and ponding at low points. The Rehab Subcode, N.J.A.C. 5:23-6.4, limits roof recover and bars a new layer over two existing layers or over wet, deteriorated decking, which directs many older buildings toward full replacement.
Thermal-imaging inspection and infrared leak detection map trapped moisture inside the assembly without cutting the membrane. Following ASTM C1153, an infrared survey locates wet insulation so repairs target failed areas rather than the entire roof.
Which Commercial Roof Systems Do We Install?
Newark Quality Roofing installs TPO, EPDM, PVC, modified bitumen, built-up roofing, commercial metal, spray polyurethane foam, and vegetated green roofs on Essex County, New Jersey buildings. Single-ply membranes carry an InterNACHI-cited service life of roughly 20 to 30 years.
TPO, EPDM, and PVC are the three single-ply membranes: TPO presents a heat-weldable reflective sheet, EPDM is a flexible black rubber proven on low-slope roofs, and PVC welds chemical- and grease-resistant seams suited to restaurants. The CRRC rates reflective membranes for solar reflectance and thermal emittance.
Modified bitumen and built-up roofing are asphalt-based multi-ply systems: modified bitumen adds polymer-reinforced cap sheets, while built-up roofing layers felts and bitumen into a redundant membrane. Both suit the flat decks common on Newark warehouses and retail blocks.
Commercial metal, spray polyurethane foam, and green roofs round out the catalog: standing-seam metal reaches a 40-to-70-year service life per InterNACHI ranges, spray foam delivers a seamless monolithic surface, and a vegetated green roof manages stormwater on the deck. Coatings add CRRC-rated reflectance, not R-value.
How Do Commercial Roof Inspections and Leak Surveys Work?
Commercial roof inspections combine a visual walkover with a non-destructive infrared moisture survey conducted under ASTM C1153 to locate trapped water inside the assembly. The survey finds wet insulation, not the leak entry point, so it guides where to open the roof.
Infrared and thermal moisture surveys read temperature differences after sundown, when saturated insulation retains heat longer than dry areas and shows as warm signatures. This maps the wet footprint across the deck so Newark Quality Roofing scopes targeted repair instead of a full tear-off.
Inspection cadence follows the NRCA recommendation of professional roof inspection twice a year and after every major storm. Regular surveys on Essex County, New Jersey commercial buildings catch seam separation and flashing failures before water reaches the deck and insulation.

What Questions Do Property Managers Ask About Commercial Roofing?
Does a commercial reroof in New Jersey require a permit?
Yes, commercial and multi-family reroofs in New Jersey require a construction permit and follow the Uniform Construction Code at N.J.A.C. 5:23. The ordinary-maintenance permit exemption applies only to detached one- and two-family homes, not commercial buildings.
Can Newark Quality Roofing recover an existing commercial roof instead of replacing it?
Sometimes, but the Rehab Subcode at N.J.A.C. 5:23-6.4 bars a new layer over two existing layers or over wet, deteriorated decking. An infrared moisture survey determines whether the existing assembly is dry enough for recover rather than full replacement.
How long does a commercial flat roof membrane last?
Single-ply membranes such as TPO, EPDM, and PVC carry an InterNACHI-cited service life of roughly 20 to 30 years, while standing-seam commercial metal reaches 40 to 70 years. Drainage, maintenance, and ponding directly affect realized lifespan.
How often should a commercial roof be inspected?
NRCA recommends professional roof inspection twice a year and after every major storm. Twice-yearly inspections on Essex County, New Jersey buildings catch seam separation, flashing failures, and ponding before water reaches the deck and insulation.
Is Newark Quality Roofing licensed for commercial roofing work in New Jersey?
Newark Quality Roofing is a registered New Jersey Home Improvement Contractor under N.J.S.A. 56:8-136 and carries liability insurance. New Jersey issues no standalone roofing license; HIC registration is the governing credential for contractor work statewide.
