What Is Built-Up Roofing?
Built-up roofing is a low-slope membrane that alternates layers of reinforcing fabric and hot bitumen on the deck, then surfaces the plies with gravel, mineral granules, or a reflective coating. The multi-ply assembly shields the membrane from UV and impact.
What Built-Up Roofing Do We Provide?

Newark Quality Roofing provides built-up roofing for commercial low-slope roofs across Essex County: 3-ply, 4-ply, and 5-ply BUR systems, gravel-surfaced and coated, plus BUR restoration and recover — primarily for commercial properties, with limited residential flat-roof work. Built-up roofing alternates layers of reinforcing fabric and hot bitumen on the roof deck, then surfaces the plies with gravel, mineral granules, or a reflective coating that shields the membrane from UV and impact.
Built-up roofing lasts 30 years, per the InterNACHI life-expectancy chart, longer than EPDM at 15–25 years, TPO at 7–20 years, and modified bitumen at 20 years. A built-up roof concentrates failures at the flashing details and the surfacing, because water enters at one transition and the gravel migrates over decades, so a Newark Quality Roofing assessment identifies the failed detail before resealing or resurfacing the system.
- Multi-ply BUR installation — Multi-ply BUR installation builds 3, 4, or 5 reinforcing-fabric plies in hot bitumen on the roof deck, the multi-ply construction that gives built-up roofing a 30-year service life, per the InterNACHI life-expectancy chart.
- Gravel-surfaced BUR — Gravel-surfaced BUR embeds aggregate in a flood coat of bitumen, the surfacing that shields the membrane plies from UV radiation and foot traffic, per NRCA low-slope roofing guidance.
- Reflective-coated BUR — Reflective-coated BUR applies a cool-roof coating over a smooth-surfaced membrane, a surface that raises solar reflectance against the dark bitumen, measured per ASTM C1549 and listed by the CRRC.
- BUR restoration and resurfacing — BUR restoration and resurfacing repairs damaged areas and applies a new surfacing layer over a sound membrane, extending the existing roof at a fraction of replacement cost, per NRCA maintenance guidance.
- BUR recover and conversion — BUR recover and conversion installs a new system over a sound existing roof, or strips the BUR to the deck for a single-ply membrane, with full removal required when the existing roof is water-soaked or already carries 2 or more layers under N.J.A.C. 5:23-6.4.
How Do You Know If You Need Built-Up Roofing?




- Alligatoring, cracking, or bald spots across the BUR surface indicate the surfacing has migrated and the bitumen plies are oxidizing, the most common end-of-life pattern on a 30-year built-up roof, per the InterNACHI life-expectancy chart.
- Blisters across the BUR surface indicate moisture trapped between the plies and developing delamination, a multi-ply failure that resurfacing addresses before the leak reaches the deck, per NRCA low-slope guidance.
- Ponding water remaining on the roof more than 48 hours counts as a defect, because a low-slope roof needs at least ¼ inch per foot of slope to drain, per NRCA and ARMA.
- A roof carrying heavy equipment service traffic or mechanical staging favors the multi-ply redundancy of built-up roofing, where the gravel surfacing absorbs impact that punctures a single-layer membrane, per NRCA low-slope guidance.
- Recurring leaks at the same flashing detail signal a systemic failure rather than an isolated breach, the threshold at which a flat roof needs replacement regardless of damaged area, per HomeAdvisor cost data.
- Damage across more than 25–30% of the membrane crosses the flat-roof replacement threshold, the point above which full replacement costs less than continued spot repair, per Parish, Modernize, and HomeGuide cost data.

How Do Our Roofing Contractors Perform Built-Up Roofing?

Newark Quality Roofing contractors assess the BUR membrane, the surfacing, the flashing details, and the drainage before specifying a built-up roof, because the plies, the gravel, and the slope each fail on a different timeline. 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 that accelerates bitumen oxidation, per NRCA and ARMA. A Newark Quality Roofing assessment sizes the ply count, the reinforcing fabric, and the surfacing against the roof traffic and the Essex County climate before tear-off.
Newark Quality Roofing builds the BUR assembly from alternating plies of reinforcing fabric and hot bitumen, then surfaces the plies with gravel or a reflective coating, the multi-ply construction that gives built-up roofing a 30-year service life. Built-up roofing lasts 30 years, per the InterNACHI life-expectancy chart, and each fully mopped ply adds an independent waterproofing layer that a single puncture does not breach to the deck. Fiberglass reinforcing fabric raises fire performance and dimensional stability, while polyester fabric raises elongation for a deck subject to structural movement, and the bitumen grade matches the roof slope and the Newark roof-surface temperatures.
Newark Quality Roofing restores a sound BUR roof through resurfacing rather than replacement, or recovers a sound membrane with a new system, the lower-cost path when the plies hold. Restoration removes or consolidates the existing gravel, repairs the damaged areas, and applies a new surfacing layer or a reflective coating that converts a heat-absorbing dark BUR surface to a cool roof, per NRCA maintenance guidance. Full removal to the deck applies when the existing roof is water-soaked or already carries 2 or more layers, per N.J.A.C. 5:23-6.4 and the NJ Rehabilitation Subcode.
What Residential Built-Up Roofing Do We Provide?
Newark Quality Roofing maintains, repairs, and resurfaces existing residential built-up roofs across Essex County on older flat-roof homes, apartment buildings, and mixed-use properties, with no construction permit required for the roof covering on a detached one- and two-family home. A repair or replacement of the roof covering on a detached one- and two-family dwelling counts as ordinary maintenance under N.J.A.C. 5:23-2.7 and requires no construction permit, no inspection, and no notice to the construction official, per the NJ Uniform Construction Code.
Built-up roofing appears on mid-twentieth-century Essex County buildings from the era when BUR was the dominant flat-roof technology, so a residential BUR job focuses on gravel redistribution, drain clearing, and resurfacing that extends a 30-year system, per the InterNACHI life-expectancy chart and NRCA maintenance guidance. When the plies reach end of life, a Newark Quality Roofing crew installs a new BUR system or converts the roof to a single-ply membrane such as EPDM at a 15–25-year life or TPO at a 7–20-year life, per the InterNACHI life-expectancy chart.

What Commercial Built-Up Roofing Do We Provide?
Newark Quality Roofing installs and restores commercial built-up roofing across Essex County on warehouses, industrial facilities, and buildings with heavy rooftop equipment service, using 3-ply to 5-ply BUR systems with gravel or reflective surfacing. Built-up roofing lasts 30 years, per the InterNACHI life-expectancy chart, and the multi-ply construction provides redundant waterproofing where a dropped tool or equipment leg that punctures a single-ply membrane only dents the gravel-armored BUR surface.
A low-slope roof needs at least ¼ inch per foot of slope to drain, with ponding water remaining more than 48 hours counted as a defect, per NRCA and ARMA. On a commercial 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, per the NJ Uniform Construction Code, and full removal to the deck applies when the existing roof is water-soaked or already carries 2 or more layers, per N.J.A.C. 5:23-6.4. A Newark Quality Roofing assessment presents 3 options for an aging BUR roof: full BUR replacement, restoration through resurfacing, or conversion to a single-ply membrane.

What Are the Steps in Our Built-Up Roofing Process?

- Assessment and System Design
A Newark Quality Roofing technician assesses the BUR membrane, the surfacing, the flashing details, and the drainage, then specifies the ply count, reinforcing fabric, bitumen grade, and surfacing against the roof traffic and the ¼-inch-per-foot minimum slope, per NRCA and ARMA drainage standards.
- Written Estimate and Permitting
A Newark Quality Roofing written estimate sets the scope, labor, materials, and timeline, and files the construction permit when a commercial roof repairs more than 25% of the total roof area in a 12-month period under N.J.A.C. 5:23-2.7, per the NJ Uniform Construction Code.
- Deck Preparation
A Newark Quality Roofing crew removes the existing roof or prepares the existing roof for recover, repairs deck deficiencies, and installs rigid insulation with a tapered configuration that creates the drainage slope and a cover board, with full removal required by N.J.A.C. 5:23-6.4 when the existing roof is water-soaked or carries 2 or more layers.
- Ply and Surfacing Construction
A Newark Quality Roofing crew mops successive reinforcing-fabric plies in hot bitumen, each ply crossing the layer below for redundant waterproofing, then embeds gravel in a flood coat or applies a reflective coating, per NRCA low-slope roofing guidance.
- Flashing and Detail Work
A Newark Quality Roofing crew details the penetrations, edges, transitions, and equipment curbs with cant strips and termination bars that tie into the field membrane, sealing the transitions where water concentrates on a low-slope roof, per NRCA flashing guidance.
- Verification, Cleanup, and Warranty
A Newark Quality Roofing lead verifies ply adhesion, surfacing coverage, flashing integrity, and positive drainage, clears the work area, and issues a written workmanship warranty on the labor, separate from the manufacturer material warranty that covers factory defects.
How Much Does Built-Up Roofing Cost?
Built-Up Roofing cost in Essex County, NJ runs $7–$12/sq ft for commercial low-slope systems, with the cost factors below setting where a given job lands in that range.
Typical Price Range
$7–$12/sq ft for commercial low-slope systems
Cost Factors:
- Commercial low-slope roofing in New Jersey runs $7–$12 per square foot installed, against an EPDM flat-roof install of $7–$10 per square foot, per Josten Roofing NJ pricing.
- Flat-roof repair runs $2.50–$10 per square foot, or $300–$1,100 for a typical repair, per HomeGuide flat-roof cost data.
- Ply count drives the installed cost, because a 4-ply or 5-ply BUR system adds reinforcing fabric and bitumen over a 3-ply system, per NRCA low-slope construction guidance.
- Surfacing adds cost, because a reflective cool-roof coating and a gravel flood coat carry different material and labor, per NRCA maintenance guidance.
- NJ ranges sit 10–40% above national figures because of higher labor and stricter NJ code, per regional cost guidance.
