What is Commercial Flat Roof Repair?
Commercial flat roof repair involves diagnosing, addressing, and fixing issues with low-slope roofing systems commonly found on commercial, industrial, and multi-unit residential buildings. Unlike residential pitched roofs, flat roofs use specialized membrane systems like TPO, EPDM, and PVC that require different repair techniques and expertise.
These roofing systems are popular on commercial buildings because they're cost-effective for large roof areas, provide space for HVAC equipment, and offer easier maintenance access. However, their low slope means water drainage is critical—and when problems occur, they require specialized commercial roofing knowledge to repair correctly.
Professional commercial flat roof repair differs significantly from residential roof work. Commercial roofs often span thousands of square feet, feature multiple penetrations for equipment and vents, and require understanding of membrane welding, flashings, and commercial-grade waterproofing systems. This is why it's essential to work with contractors who specialize in commercial roofing rather than general roofers.
Common Commercial Flat Roof Problems We Repair
Understanding common flat roof issues helps you identify problems early—before minor repairs become major expenses. Here are the most frequent issues we encounter on Essex County commercial buildings:
Ponding Water & Drainage Issues
Ponding water is standing water that remains on your roof 48+ hours after rainfall. It's one of the most common—and damaging—flat roof problems. Causes include clogged drains, improper roof slope, sagging deck areas, or compressed insulation. Left unaddressed, ponding water accelerates membrane deterioration, adds structural stress, and eventually causes leaks.
Our repair approach addresses both the immediate issue (improving drainage, repairing low spots) and the root cause (clearing drains, adding tapered insulation) to prevent recurrence.
Membrane Damage & Punctures
Flat roof membranes can be damaged by foot traffic during HVAC maintenance, falling debris, hail, or wildlife. Punctures and tears compromise the waterproof barrier, allowing moisture infiltration into the insulation and building interior. Even small punctures can cause significant damage over time.
We repair membrane damage using manufacturer-approved materials and techniques, ensuring repairs match your existing roofing system and maintain warranty coverage.
Seam & Flashing Failures
Flat roof seams—where membrane sheets join together—are common failure points. Weather cycling, UV exposure, and age cause seams to separate, creating paths for water intrusion. Similarly, flashing around penetrations (pipes, vents, HVAC units, skylights) can fail, allowing water to enter at these vulnerable transitions.
Our technicians are trained in proper seam welding and flashing installation for all major flat roofing systems, ensuring watertight repairs that last.
Blistering & Bubbling
Blisters form when moisture or air becomes trapped beneath the membrane, causing it to bubble up. Small blisters may be monitored, but larger ones risk puncture and should be professionally repaired. Blistering often indicates installation issues or moisture problems within the roof assembly.
Storm & Weather Damage
Essex County experiences severe weather—from nor'easters to summer storms—that can damage flat roofs through wind uplift, hail impact, and debris. Storm damage requires prompt attention to prevent secondary water damage to your building interior and inventory.
R&E Roofing offers 24/7 emergency roof repair for storm-damaged commercial roofs, including temporary tarping and rapid permanent repairs.

Types of Commercial Flat Roofs We Repair in Essex County
Different flat roofing systems require different repair approaches. Our technicians are trained and certified to repair all major commercial flat roofing systems:
TPO (Thermoplastic Polyolefin) Roofing
TPO is one of the fastest-growing commercial roofing options, valued for its energy efficiency, durability, and cost-effectiveness. The white reflective surface reduces cooling costs, making it popular in Essex County's hot summers.
Common TPO repairs: Seam failures (heat-welded seams can separate), punctures, flashing repairs around penetrations, and membrane patches. TPO repairs require specialized hot-air welding equipment and manufacturer-certified installation.
EPDM (Rubber) Roofing
EPDM (ethylene propylene diene monomer) is a durable rubber membrane known for excellent weather resistance and longevity. It's commonly found on older commercial buildings throughout Essex County.
Common EPDM repairs: Seam separation (adhesive seams weaken over time), shrinkage issues, punctures, and flashing failures. EPDM repairs use special primers, adhesives, and uncured rubber patches to create seamless repairs.
PVC Roofing
PVC (polyvinyl chloride) roofing offers superior chemical resistance, making it ideal for restaurants, factories, and buildings with rooftop equipment that may leak oils or chemicals.
Common PVC repairs: Heat-welded seam repairs, membrane patching, flashing replacement. PVC's heat-welded seams create strong bonds but can fail with age or poor installation.
Modified Bitumen Roofing
Modified bitumen combines asphalt with rubber or plastic modifiers for improved flexibility and durability. It's applied in overlapping layers and is common on commercial buildings built between the 1970s and 2000s.
Common repairs: Blister repairs, seam re-sealing, cap sheet replacement, and coating applications to extend lifespan.
Built-Up Roofing (BUR)
Traditional built-up roofs feature multiple layers of bitumen and reinforcing fabrics topped with gravel or a cap sheet. While durable, BUR roofs require specialized repair knowledge.
Common repairs: Blister cutting and patching, re-coating, gravel redistribution, and flashing repairs. Learn more about our flat roofing services.
