Overview
EPDM commercial roofing is the proven workhorse of the flat roof industry, with more square footage installed on commercial buildings than any other single-ply membrane in North America. The material's track record spans more than five decades, with the earliest installations from the 1960s still in service, providing unmatched real-world performance data that gives building owners confidence in specifying EPDM for their commercial properties. In Essex County, where commercial buildings range from small retail spaces to massive warehouses and industrial complexes, EPDM's scalability and proven reliability make it a cornerstone of commercial roofing practice.
The commercial-grade EPDM systems we install differ from residential applications in scale, engineering, and warranty coverage. Commercial EPDM membranes are available in sheets up to 50 feet wide and hundreds of feet long, allowing large roof areas to be covered with minimal field seams. The membrane thickness ranges from 45 to 90 mil depending on the project requirements, with 60-mil being standard and 90-mil specified for enhanced puncture resistance and longer warranty periods. These large-format, heavy-duty membranes are engineered specifically for the demands of commercial buildings where the roof protects not just the structure but the business operations, equipment, and inventory below.
Newark Quality Roofing holds commercial applicator certifications from Firestone Building Products, Carlisle SynTec, and Johns Manville, the three leading manufacturers of commercial EPDM systems. These certifications require demonstrated installation quality, ongoing training, and financial stability verification, and they qualify our installations for the premium warranty programs that manufacturers reserve for their certified applicator network. For commercial property owners, this certification means maximum warranty protection backed by major manufacturers with the financial resources to honor their commitments.
EPDM's chemical composition -- a synthetic rubber polymer derived from ethylene, propylene, and a diene monomer -- gives the membrane outstanding resistance to ultraviolet radiation, ozone, and weathering. Unlike thermoplastic membranes that rely on chemical stabilizers to resist UV degradation, EPDM's inherent molecular structure provides UV resistance without additives that can deplete over time. This fundamental stability is the reason EPDM membranes from the 1960s and 1970s are still in service today, a performance record that no other single-ply membrane can match. The material's flexibility at low temperatures is equally impressive: EPDM remains fully pliable at minus 40 degrees Fahrenheit, a characteristic that prevents the thermal stress cracking that can affect rigid membranes during Essex County's harshest winter conditions. For freeze-thaw cycling -- where the roof membrane expands and contracts dozens of times each winter as temperatures fluctuate above and below freezing -- EPDM's elastic recovery ensures the membrane returns to its original dimension without fatigue or permanent deformation.
The three primary attachment methods for commercial EPDM each serve distinct building requirements. Mechanically attached EPDM uses bar-over-membrane fastening with plates that grip the membrane against the deck, providing positive wind uplift resistance suitable for tall buildings or high-wind exposure zones. Fully adhered EPDM bonds the membrane to the substrate with contact adhesive, creating a smooth, attached surface that resists wind flutter and provides excellent performance on buildings with complex geometry or aesthetic requirements. Ballasted EPDM is held in place by a layer of river-washed stone, typically 10 to 12 pounds per square foot, offering the lowest installed cost and simplest installation but requiring structural capacity to support the ballast weight. Our engineering analysis for each Essex County building evaluates wind exposure, structural capacity, and project budget to determine the optimal attachment method.

Signs You Need EPDM Commercial Roofing
- Your commercial building needs a flat roof system with the longest proven performance history available
- The existing commercial roof membrane has reached end of life with widespread deterioration, seam failures, or chronic leaking
- You want a membrane that performs reliably in extreme cold temperatures without becoming brittle or cracking
- Budget considerations favor a cost-effective membrane with proven long-term value over premium-priced alternatives
- The building's roof sees minimal foot traffic and does not have chemical exposure that would favor other membrane types
- You are consolidating multiple roof sections under a single membrane system to simplify maintenance and warranty management

Our EPDM Commercial Roofing Approach
Commercial EPDM installation begins with engineering analysis that considers the building's wind exposure, structural capacity, insulation requirements, and drainage needs. Wind uplift calculations determine the attachment system, whether mechanically fastened, fully adhered, or ballasted with stone. Insulation specification satisfies current New Jersey energy codes while tapered sections create positive drainage to internal roof drains. The entire assembly is designed as an integrated system where each component supports the performance of the others.
For large commercial buildings, we develop detailed installation sequences that minimize the time any section of the building is exposed during work. The tear-off, insulation, and membrane installation proceeds in manageable sections so that emergency weather protection can be deployed quickly if conditions change. This phased approach is especially important for occupied commercial buildings where a sudden rainstorm during construction could damage interior spaces, inventory, or operations. Our project management includes weather monitoring and contingency protocols for every commercial installation.
Seam construction on commercial EPDM installations uses six-inch-wide seam tape with splice adhesive and primer, creating a fully cured bond that resists peel forces and maintains integrity through decades of thermal cycling. Our quality assurance protocol includes seam probing at regular intervals, adhesive coverage verification, and documented testing that becomes part of the permanent project record. For manufacturer warranty qualification, this documentation demonstrates that the installation meets the quality standards the warranty is predicated upon.
Insulation design for commercial EPDM assemblies follows the same thermal performance standards required for any flat roofing system in New Jersey. Current energy code requirements demand minimum R-25 to R-30 continuous insulation for commercial roof assemblies, achieved through multiple layers of polyisocyanurate board with staggered joints. Tapered insulation crickets create positive drainage slope of at least one-quarter inch per foot toward roof drains, eliminating the ponding water conditions that accelerate membrane aging and void manufacturer warranties. Cover boards above the insulation protect it from mechanical damage during installation and long-term service, and the cover board selection -- gypsum, high-density polyiso, or mineral fiber -- depends on the project's fire rating requirements and the attachment method specified. For recover projects where new EPDM is installed over an existing membrane, moisture surveys using infrared thermography or nuclear testing identify wet insulation areas that must be removed and replaced before the new system is installed.
EPDM Roofing for Residential Applications
Although this service page focuses on commercial EPDM systems, the technology is equally applicable to residential flat roof sections. Many Essex County homes, particularly row homes, brownstones, and contemporary designs, include flat or low-slope roof sections that benefit from EPDM's proven reliability and cold-weather flexibility. We install commercial-grade EPDM membrane on residential flat roofs using the same materials, techniques, and quality standards as our commercial work.
For homeowners considering EPDM, the material's advantages include a 50-year performance track record, excellent flexibility in freezing temperatures, straightforward repairability, and competitive installed cost. The standard black color absorbs solar heat, which can be an advantage during Essex County's heating-dominant winter months but a disadvantage during summer cooling. White EPDM membrane is available for homeowners who prioritize cooling efficiency, though it costs modestly more than the standard black product.
Residential EPDM installations carry manufacturer warranty coverage of 15 to 25 years depending on membrane thickness and attachment method. Our workmanship warranty supplements the manufacturer coverage to provide comprehensive protection. The combination of proven long-term performance, simple maintenance requirements, and strong warranty coverage makes EPDM an excellent value for residential flat roof applications.
Multi-family residential buildings in Newark, East Orange, Bloomfield, and throughout Essex County represent a significant share of our residential EPDM installations. Apartment buildings, townhome complexes, and condominium associations benefit from EPDM's combination of proven reliability and competitive cost, which is particularly attractive when the roofing budget must serve a large number of unit owners or tenants. The membrane's flexibility during winter months prevents the thermal stress cracking that can create leaks in less elastic materials, protecting the units below from water damage that disrupts tenants and creates costly interior repair obligations for building owners and property managers.
Commercial EPDM Roofing
Commercial EPDM roofing delivers the combination of proven performance, competitive cost, and strong warranty coverage that commercial property owners and managers require. The material's half-century of documented field performance eliminates the uncertainty that newer materials inevitably carry, providing a risk-managed roofing investment backed by the longest performance record in the single-ply membrane category. For building owners who value proven reliability over the newest technology, EPDM is the clear choice.
The total cost of ownership for commercial EPDM is among the lowest in the flat roofing category when initial cost, maintenance requirements, and expected service life are all considered. Initial installed cost is competitive with TPO and lower than PVC. Maintenance requirements are modest, consisting primarily of annual inspection, drain clearing, and periodic seam inspection. And the documented 30 to 50-year service life means that a single EPDM installation can serve the building for decades before replacement becomes necessary, spreading the initial investment over an exceptionally long period.
For commercial portfolio owners managing multiple buildings, standardizing on EPDM from a single manufacturer through a certified applicator simplifies specification, quality assurance, and warranty management. We can develop master specifications for portfolio-wide EPDM installations that maintain consistency across buildings while accommodating the specific requirements of individual properties. Volume pricing, coordinated scheduling, and centralized warranty management are all available for portfolio clients who consolidate their commercial roofing work with our company.
Warranty structures for commercial EPDM installations offer building owners multiple tiers of protection. Standard material-only warranties cover membrane defects for 15 to 20 years at no additional cost beyond the certified installation. Premium no-dollar-limit warranties add full labor coverage for the warranty period, meaning the manufacturer pays all costs for any warranty-related repair including labor, materials, and consequential damage to building contents in some programs. The highest-tier warranties, often called NDL or total system warranties, provide 20 to 30-year coverage with no financial cap on repair or replacement costs, transferability to new building owners, and consequential damage protection that covers interior property damaged by a warranty-covered roof failure. Our certified applicator status with Firestone, Carlisle, and Johns Manville qualifies every commercial installation for the premium warranty tier each manufacturer offers, giving Essex County building owners the strongest manufacturer-backed protection available in the market. For property owners conducting total cost of ownership analysis, the warranty term and coverage level should be factored into lifecycle cost projections alongside initial cost, maintenance expenses, and projected replacement timing.
