What Is EPDM Commercial Roofing?
EPDM commercial roofing is a single-ply synthetic-rubber membrane installed on flat and low-slope commercial roofs to seal the building against water entry. EPDM attaches mechanically, fully adheres, or holds under ballast, with the splice seams joining the sheets.
What EPDM Commercial Roofing Is Available in Montclair?
Newark Quality Roofing installs and services EPDM commercial roofing across Montclair: mechanically attached, fully adhered, and ballasted rubber membrane on the attached storefronts and two- and three-family rooflines. That work runs the Bloomfield Avenue corridor, Watchung Plaza, and the Upper Montclair business district. EPDM seals the flat and low-slope roof in a single-ply rubber membrane against water entry.
Mechanically attached, fully adhered, and ballasted membrane match the attachment method to each Montclair building, because EPDM resists wind uplift, flutter, and complex geometry differently. A Newark Quality Roofing install sizes the attachment against the NJ design wind speed per ASCE 7 as adopted by the NJ Uniform Construction Code, with the First Watchung ridge slopes on the township's west side standing more exposed to gusts than the valley lots.
Rubber membrane suits the commercial and multi-unit angle of Montclair, where roughly 54% of units sit in multi-unit structures, per the U.S. Census Bureau, and the period storefronts along Montclair Center carry flat and low-slope decks. EPDM lasts 15 to 25 years, per the InterNACHI life-expectancy chart, and a service-life study attributed via Progressive Materials places EPDM at 25 to 30 years.
Single-ply rubber fails most often at the splice seams, with membrane shrinkage and ponding water as secondary failure modes, per NRCA technical guidance, so a Newark Quality Roofing install seam-bonds the membrane and engineers positive drainage before the roof carries water. Reservation-edge and street-canopy leaf load that collects on Montclair's low-slope decks accelerates that aging where standing water lingers.
What EPDM Commercial Roofing Problems Are Common in Montclair?
Seam separation ranks as the dominant EPDM failure mode on Montclair low-slope roofs, per NRCA technical guidance, with membrane shrinkage pulling the sheet away from parapets and penetrations as a secondary mode. A Newark Quality Roofing install bonds the splice seams with primer, splice tape, and lap adhesive to manufacturer specification rather than adhesive alone.
Ponding water standing more than 48 hours counts as a defect that stretches and ages the membrane, because a low-slope roof needs at least ¼ inch per foot of slope to drain, per NRCA and ARMA. Heavy street-canopy and reservation-edge leaf load blocks the drains and scuppers on Montclair's Bloomfield Avenue and Watchung Plaza decks, so a Newark Quality Roofing scope grades the deck to drain.
Parapet and penetration flashing opens at the masonry parapets and the rooftop HVAC, vent, and equipment curbs on Montclair's older attached storefronts and two- and three-family additions. A Newark Quality Roofing install reflashes those transitions with manufacturer-approved EPDM components, the detail work that addresses the membrane shrinkage and seam failure that drive EPDM leaks, per NRCA technical guidance.

What Is Our Process for EPDM Commercial Roofing in Montclair?
Newark Quality Roofing inspects the deck and existing membrane, sizes the wind-uplift attachment, and designs the insulation and drainage slope before tear-off. A crew core-samples the existing insulation for moisture, because the NJ Rehabilitation Subcode requires complete removal of a water-soaked covering or a roof already carrying 2 or more layers, per N.J.A.C. 5:23-6.4, and surveys every penetration and parapet on the Montclair building.
Newark Quality Roofing files the permit a commercial EPDM roof requires, then installs continuous rigid insulation and tapered slope under the membrane. On a commercial, multi-family, or attached building, repairing more than 25% of the total roof area in a 12-month period requires a permit under N.J.A.C. 5:23-2.7, filed through the Township of Montclair Building Office, and the insulation is set in staggered layers to at least ¼ inch per foot of slope, the drainage that clears the ponding NRCA and ARMA count as a defect after 48 hours.
Newark Quality Roofing sets the EPDM membrane, seam-bonds the splice laps to manufacturer specification, flashes the details, and registers the manufacturer warranty. Splice seams join with primer, splice tape, and lap adhesive, and the flashing at parapets, curbs, and penetrations seals with manufacturer-approved EPDM components, keeping the manufacturer material warranty intact alongside the written workmanship warranty on the labor.
