When it comes to roofing in New Jersey, whether you’re downtown Jersey City or up in Morris County, understanding what commercial roofing is called can save you heaps of confusion — and dollars. Commercial roofing isn’t just “roofing” slapped onto a building. It’s a specialized, complex system designed for large-scale structures like warehouses, office buildings, retail stores, and industrial facilities. With Charles Jimerson of CJ Commercial Roofing NJ, we’ll break down what commercial roofing actually is, its types, terminology, and why it matters especially for businesses across New Jersey.

Understanding Commercial Roofing: What’s in a Name?
The term commercial roofing broadly refers to roofing systems installed on commercial properties — basically, non-residential buildings. Unlike residential roofing, which covers homes, commercial roofs often come with unique materials, designs, and maintenance needs tailored for bigger spaces and different uses.
But here’s the insider scoop: commercial roofing is also frequently called “flat roofing” or “low-slope roofing” because most commercial buildings feature roofs with minimal pitch. This distinction is critical in New Jersey’s climate, where the balance between drainage and insulation can make or break a roof’s lifespan.
Types of Commercial Roofing: Decoding the Jargon
So, what exactly is commercial roofing called beyond just the umbrella term? Here’s a breakdown of the most common types you’ll encounter in New Jersey commercial roofing projects:
1. Built-Up Roofing (BUR)
AKA “tar and gravel roofing,” BUR is one of the oldest and most reliable commercial roofing systems. It’s made by layering bitumen (tar) and reinforcing fabrics, then topping it with gravel for UV protection. You’ll see BUR on older warehouses and factories throughout New Jersey, especially in industrial hubs like Newark and Paterson.
2. Modified Bitumen Roofing
This modern twist on BUR incorporates polymer-modified asphalt to increase elasticity and durability. Modified bitumen roofs are usually installed in sheets and torched down, providing enhanced waterproofing — crucial for New Jersey’s heavy rains and snow.
3. EPDM Roofing (Ethylene Propylene Diene Monomer)
Pronounced “E-P-D-M,” this synthetic rubber membrane is super popular for commercial flat roofs. It’s durable, flexible, and highly resistant to weather extremes — perfect for the varied climate across New Jersey, from urban centers to coastal towns like Cape May.
4. TPO Roofing (Thermoplastic Olefin)
TPO is a single-ply membrane roofing system that’s gaining traction because it’s lightweight, reflective (energy-efficient), and heat-welded for strong seams. It’s often found on newer commercial buildings around the Meadowlands and other business districts in New Jersey.
5. PVC Roofing (Polyvinyl Chloride)
PVC roofs are similar to TPO but offer superior chemical resistance, making them ideal for commercial properties like restaurants and manufacturing plants in New Jersey that might face chemical exposure.

Why Is Knowing the Commercial Roofing Name Important in New Jersey?
Understanding the correct terminology isn’t just geeky jargon; it has real-world implications for maintenance, insurance, and regulatory compliance in New Jersey:
- Insurance & Warranties: Insurance providers in New Jersey ask for specific roof types to determine risk and premiums. Calling it by the right name helps avoid claim disputes.
- Building Codes: New Jersey’s state and local building codes may mandate specific roofing materials or installation methods depending on your commercial roofing system.
- Maintenance: Knowing whether you have a TPO or modified bitumen roof guides your maintenance schedule, especially with New Jersey’s mix of humid summers and snowy winters.
- Energy Efficiency: Choosing the right commercial roof type impacts energy costs. For example, reflective TPO roofs reduce cooling costs in New Jersey’s hot summers.
