What Is Modified Bitumen Roofing?
Modified bitumen roofing is a multi-ply low-slope membrane that layers a polymer-modified asphalt cap sheet over base plies on the deck. The polymer modifier, styrene-butadiene-styrene or atactic polypropylene, adds flexibility to the redundant, built-up asphalt assembly.
What Modified Bitumen Roofing Is Available in Irvington?
Newark Quality Roofing installs modified bitumen roofing across Irvington's dense building stock — Springfield Avenue and Chancellor Avenue commercial flat roofs, Route 78 southeastern-edge light-industrial buildings, and the low-slope sections of two- and three-family rentals. Modified bitumen layers a polymer-modified asphalt cap sheet over base plies, the multi-ply assembly that carries the redundancy of built-up roofing with added membrane flexibility.
The multi-ply assembly suits Irvington's aging commercial and rental stock, because a breach in the cap sheet stops short of the deck and the redundant plies absorb the foot traffic and concentrated loads of HVAC service access that puncture a single-ply membrane, per ARMA modified-bitumen guidance. Modified bitumen lasts 20 years, per the InterNACHI life-expectancy chart, against EPDM at 15 to 25 years, TPO at 7 to 20 years, and BUR at 30 years.
SBS-modified bitumen holds low-temperature flexibility better than APP-modified bitumen, the property that matters across the cold-weather cycling that Irvington shares with Newark, per ARMA modified-bitumen guidance. A Newark Quality Roofing installation matches the polymer modifier and the application method — SBS torch, SBS self-adhered, APP torch, or cold adhesive — to the building, the occupancy, and the NJ fire-code conditions before the first ply.
What Modified Bitumen Roofing Problems Are Common in Irvington?
Tenant-occupied access shapes a modified bitumen job on Irvington's many two- and three-family and investor-owned buildings, because the township is majority-renter and rental- and multi-family-heavy, so the work coordinates entry around occupants under New Jersey landlord-tenant notice. A Newark Quality Roofing job applies self-adhered SBS or cold-adhesive membrane to eliminate open flame on an occupied building and documents the work for the owner.
Torch application near combustible details requires the NRCA hot-work protocol on Irvington's densely built commercial corridors, where Springfield Avenue and Chancellor Avenue storefronts share parapet walls with adjacent buildings. A Newark Quality Roofing crew follows NRCA hot-work fire-watch protocol with fire extinguishers and a post-application fire watch, or specifies a flame-free self-adhered or cold-adhesive method where occupancy or NJ fire code restricts hot work.
Aging plank decking turns up at tear-off on Irvington's older pre- and immediate-postwar buildings, where decades of re-coating have masked blistering, splitting, and delamination beneath the surface. A Newark Quality Roofing crew strips the existing roof to the deck, replaces deteriorated decking exposed at tear-off, and installs the new multi-ply assembly over rigid polyisocyanurate insulation rather than recovering a failed substrate.
Ponding water held more than 48 hours counts as a defect that breaks down bituminous membrane, and a low-slope roof needs at least ¼ inch per foot of slope to drain, per NRCA and ARMA. A Newark Quality Roofing installation sets tapered polyisocyanurate insulation that establishes positive drainage where the existing deck on a flat Irvington commercial roof is level or improperly pitched.

What Is Our Process for Modified Bitumen Roofing in Irvington?
Newark Quality Roofing specifies the assembly and the drainage before tear-off, setting the ply count, the polymer modifier, the application method, and the insulation against the building's traffic load and the NJ code. A crew designs tapered polyisocyanurate insulation to positive drainage, because a low-slope roof needs at least ¼ inch per foot of slope to drain and ponding water remaining more than 48 hours counts as a defect, per NRCA and ARMA, and coordinates tenant access in advance on Irvington's occupied two- and three-family buildings.
Newark Quality Roofing strips the roof to the deck, repairs the exposed decking, and builds the multi-ply membrane: a base sheet, one or two interply membranes, and a polymer-modified cap sheet, each ply bonded to the layer below. The crew applies the membrane by the specified method — SBS torch, SBS self-adhered, APP torch, or cold adhesive — and verifies full-surface adhesion at each ply, re-applying any section showing incomplete contact, per ARMA modified-bitumen guidance.
Newark Quality Roofing details every penetration, curb, edge, and parapet wall with modified bitumen flashing components and documents the completed roof. Flashing separation at penetrations and parapets ranks among the most common low-slope leak sources, per NRCA and ARMA. A granulated cap sheet carries built-in UV and foot-traffic protection, while a smooth cap sheet receives a reflective coating rated for solar reflectance by the Cool Roof Rating Council. Timestamped photographs of concealed conditions support the owner's record and any insurance claim.
