When it comes to commercial roofing in New Jersey, business owners are often taken aback by the high costs associated with installation, maintenance, and repairs. The expense of a commercial roof isn’t just about materials—it’s a combination of factors such as labor, building codes, climate considerations, and long-term durability. With Charles Jimerson of CJ Commercial Roofing NJ, we’ll break down why commercial roofs are so expensive and how businesses in New Jersey can make informed decisions to protect their investments.

1. Material Costs and Roofing Types
One of the primary reasons commercial roofs are costly is the type of materials used. Unlike residential roofs, which often utilize asphalt shingles, commercial buildings typically require materials that can withstand heavy loads, extreme weather, and long-term exposure to environmental stressors.
Popular commercial roofing materials include:
- TPO (Thermoplastic Polyolefin): Known for its energy efficiency and durability but requires precise installation to avoid leaks.
- EPDM (Ethylene Propylene Diene Monomer): A rubber membrane that provides excellent weather resistance but has high material costs.
- PVC Roofing (Polyvinyl Chloride): More expensive but offers superior resistance to chemicals, moisture, and fire.
- Metal Roofing: Offers longevity and durability but comes at a premium price due to material and labor costs.
- Built-Up Roofing (BUR): A traditional asphalt-based system that requires multiple layers, increasing labor and material costs.
In New Jersey, where seasonal temperature fluctuations and extreme weather events like Nor’easters and hurricanes are common, choosing the right roofing material is crucial. High-quality materials that can withstand harsh conditions naturally come with a higher price tag.
2. Labor Costs and Skilled Workmanship
Installing a commercial roof isn’t just about laying materials—it requires highly skilled labor. The complexity of commercial roof designs, which often include multiple layers, insulation, and drainage systems, means that expert roofers like Charles Jimerson of CJ Commercial Roofing NJ are needed to ensure proper installation.
New Jersey’s labor market is also a contributing factor. The state has a relatively high cost of living, which translates into higher wages for skilled tradespeople. Additionally, strict OSHA (Occupational Safety and Health Administration) regulations demand extensive safety training, which adds to labor costs.
3. Permits, Building Codes, and Regulations
New Jersey has some of the most stringent building codes in the country, particularly in areas like Newark, Jersey City, and Trenton. Businesses must comply with local ordinances and obtain proper permits before starting a commercial roofing project.
Some key regulatory factors include:
- Energy codes: Many commercial roofs must meet insulation standards to improve energy efficiency.
- Fire codes: Certain materials must be fire-resistant, which increases costs.
- Drainage regulations: Proper drainage systems must be in place to prevent water damage and comply with city codes.
- Wind resistance requirements: Due to frequent coastal storms, roofs in areas like Atlantic City and Cape May must meet specific wind uplift standards.
Navigating these regulations requires experienced professionals, adding to the overall project expense.
4. Insulation and Energy Efficiency Standards
Many commercial buildings in New Jersey must adhere to strict energy efficiency standards, which often necessitate high-quality insulation. Poor insulation can lead to significant energy loss, increasing heating and cooling costs.
Materials like rigid foam insulation, spray polyurethane foam (SPF), and reflective roof coatings are commonly used to improve energy efficiency but can add to the overall expense. While these investments increase upfront costs, they can save businesses thousands of dollars in utility bills over time.
5. Roof Size and Design Complexity
The size of a commercial roof is another major cost factor. Unlike residential homes, which have relatively small roof footprints, commercial buildings—especially warehouses, shopping centers, and office complexes—require extensive roofing systems.
Additionally, many commercial roofs have complex designs, including:
- HVAC and ventilation systems: Large-scale commercial HVAC units require additional support structures.
- Skylights and solar panels: While these features enhance energy efficiency, they also require specialized installation techniques.
- Multiple roof levels: Some buildings, particularly in cities like Princeton and Camden, have multi-tiered roofs, which demand more labor and materials.
6. Maintenance and Long-Term Costs
A commercial roof is a long-term investment, and regular maintenance is essential for ensuring its longevity. Neglecting routine inspections and repairs can lead to costly damage, such as leaks, mold growth, and structural deterioration.
Regular maintenance involves:
- Annual inspections to identify potential issues early.
- Cleaning and debris removal to prevent clogged drains and water pooling.
- Sealant and coating applications to enhance weather resistance.
- Repairing minor damages before they escalate into major problems.
Business owners in New Jersey must factor in these ongoing costs when budgeting for their commercial roofing system.
7. Insurance and Liability Costs
Given the high costs associated with commercial roofing, many businesses opt for extensive insurance coverage. However, insurance premiums for commercial properties in New Jersey tend to be higher due to extreme weather risks, urban congestion, and liability concerns.
Additionally, roofing contractors must carry extensive insurance policies, including:
- Workers’ compensation insurance to cover employee injuries.
- General liability insurance to protect against property damage claims.
- Manufacturer warranties that cover materials but often come at an added cost.
These insurance expenses are built into the overall price of commercial roofing services.
8. Supply Chain and Market Conditions
The cost of roofing materials has fluctuated significantly in recent years due to supply chain disruptions, material shortages, and inflation. In densely populated states like New Jersey, high demand for commercial construction has further driven up prices.
Key market factors include:
- Rising material costs for steel, asphalt, and insulation.
- Increased fuel prices affecting transportation expenses.
- Tariffs on imported roofing materials, impacting availability and pricing.
Businesses should work with roofing contractors who source materials strategically to mitigate these costs.
Conclusion: Is a Commercial Roof Worth the Investment?
While the cost of commercial roofs in New Jersey may seem high, investing in a durable, energy-efficient, and properly installed roofing system can pay off in the long run. A well-maintained roof protects the structural integrity of your building, reduces energy costs, and minimizes the risk of unexpected repairs.
If you’re considering a commercial roofing project in New Jersey, working with experienced, licensed professionals ensures compliance with local regulations and guarantees long-term value. By understanding the key factors that contribute to commercial roofing expenses, business owners can make informed decisions that safeguard their properties for years to come.
