The roofing industry in New Jersey is both competitive and profitable, driven by a mix of residential and commercial projects. If you’re considering entering the roofing business or simply curious about the financial aspects, understanding how much profit roofers make on a roof is essential. Factors such as labor costs, material expenses, local regulations, and market demand all play a role in determining profitability. Let’s get to understand more on these with Charles Jimerson of CJ Commercial Roofing NJ.

Understanding Roofing Profit Margins
The average profit margin for roofing contractors varies depending on job type, location, and business structure. In general, residential roofing jobs tend to have higher profit margins than commercial projects due to lower material and labor costs. Most roofing businesses operate with gross profit margins between 20% and 40%, while net profit margins typically fall between 5% and 15% after deducting overhead costs such as equipment, labor, marketing, and administrative expenses.
Key Factors Influencing Roofing Profits in New Jersey
New Jersey presents unique challenges and opportunities for roofing contractors. Here are some of the primary factors that impact profitability:
1. Material Costs
The cost of roofing materials can significantly influence profit margins. In New Jersey, common roofing materials and their estimated costs per square (100 square feet) include:
- Asphalt Shingles – $90 to $150 per square
- Metal Roofing – $300 to $1,200 per square
- Slate Roofing – $600 to $1,500 per square
- Flat Roofing (EPDM, TPO, PVC) – $400 to $900 per square
Choosing the right material based on local demand and cost-effectiveness is key to maintaining profitability.
2. Labor Costs
New Jersey has a higher-than-average cost of labor compared to other states. Skilled roofing labor can range from $20 to $50 per hour, depending on experience and certifications. Additionally, labor union regulations in cities like Newark, Trenton, and Jersey City can impact wage structures.
3. Local Regulations & Permits
Roofing businesses must comply with state and municipal building codes. Permitting fees vary by county and can add anywhere from $100 to $1,000 to a roofing job. Contractors must ensure that all projects adhere to New Jersey’s Uniform Construction Code (UCC) to avoid costly penalties.
4. Seasonal Demand & Market Competition
Roofing is a seasonal business in New Jersey due to cold winters. Peak season runs from March to November, when demand is highest. Roofing businesses that optimize scheduling and pricing strategies during these months can maximize profitability.
5. Overhead & Business Expenses
In addition to labor and materials, other expenses impact net profit margins:
- Insurance Costs: Roofing contractors need liability and workers’ compensation insurance, which can cost between $10,000 and $30,000 annually.
- Marketing & Advertising: Google Ads, SEO, and local listings can cost $2,000 to $10,000 per year.
- Equipment & Vehicle Costs: Trucks, scaffolding, and safety gear require regular investment.
How Much Do Roofers in New Jersey Make Per Job?
The total profit per roofing project depends on the job size and complexity. Below is an estimated breakdown for different types of roofing projects in New Jersey:
- Small Residential Roof (1,500 sq. ft.)
- Estimated Revenue: $6,000 – $9,000
- Estimated Costs: $4,000 – $6,500
- Profit: $2,000 – $3,500
- Mid-Sized Residential Roof (2,500 sq. ft.)
- Estimated Revenue: $9,000 – $15,000
- Estimated Costs: $6,000 – $10,500
- Profit: $3,000 – $4,500

- Estimated Costs: $10,000 – $17,500

Commercial roofing jobs, while lucrative, often have lower profit margins due to larger material and labor costs. However, volume-based contracts can offset lower margins with steady cash flow.
Maximizing Profitability in the Roofing Industry
To increase profits in the competitive New Jersey roofing market, consider the following strategies:
1. Optimize Material Sourcing
Establishing relationships with bulk suppliers or local distributors in cities like Paterson, Camden, or Edison can reduce costs and increase margins.
2. Invest in SEO & Digital Marketing
A strong online presence can help generate leads without relying solely on paid advertising. Ranking for keywords like “roofing contractors in Newark” or “best roofers in New Jersey” can drive organic traffic and reduce customer acquisition costs.
3. Offer Financing Options
Providing homeowners with flexible financing can increase conversion rates and average transaction values. Partnering with lenders allows roofers like Charles Jimerson of CJ Commercial Roofing NJ to close more deals.
4. Upsell & Cross-Sell Services
Offering additional services such as gutter installation, roof inspections, or attic insulation can boost profits and improve customer retention.
5. Streamline Operations
Using roofing management software for scheduling, invoicing, and customer relationship management (CRM) can help reduce administrative costs and improve efficiency.
Conclusion
Roofing can be a highly profitable business in New Jersey, with net profit margins ranging from 5% to 15% depending on factors such as labor costs, material expenses, and operational efficiencies. By leveraging digital marketing, streamlining operations, and optimizing sourcing, roofing contractors can maximize profits while providing high-quality services to homeowners and businesses.
