Introduction
If you’re asking, “How do I become a commercial roofer?”—especially in New Jersey—you’re in the right place. Commercial roofing is a lucrative career path, offering stability, high earning potential, and growth opportunities. With New Jersey’s diverse climate and bustling commercial sector, the demand for skilled roofers is consistently high.

This guide outlines the essential steps to becoming a commercial roofer in New Jersey like Charles Jimerson of CJ Commercial Roofing NJ, covering training, licensing, certifications, and local industry insights.
Understanding the Role of a Commercial Roofer
Commercial roofers specialize in installing, maintaining, and repairing roofing systems for businesses, warehouses, and industrial buildings. Unlike residential roofing, commercial roofing involves flat or low-slope roofs and requires expertise in materials like TPO, EPDM, metal, and modified bitumen.
Key Responsibilities
- Inspecting and diagnosing roofing issues
- Installing new commercial roofing systems
- Conducting repairs and routine maintenance
- Ensuring compliance with New Jersey building codes
- Understanding and implementing safety protocols
Step 1: Obtain a High School Diploma or GED
Most employers and apprenticeship programs require at least a high school diploma or GED. Courses in math, shop, and construction technology can provide a strong foundation.
Step 2: Gain Hands-on Experience Through Apprenticeships
One of the best ways to break into the commercial roofing industry is through an apprenticeship. In New Jersey, unions like the United Union of Roofers, Waterproofers & Allied Workers Local 4 offer structured training programs combining classroom education with on-the-job training.
Benefits of Apprenticeships
- Earn while you learn
- Receive mentorship from experienced professionals
- Gain practical experience with commercial roofing materials and tools
Step 3: Enroll in a Vocational or Trade School
While not mandatory, attending a trade school can accelerate your learning and make you more competitive in the job market. Schools like New Jersey Institute of Technology (NJIT) or Lincoln Tech in Mahwah offer construction and roofing-related courses.
Skills Acquired
- Roofing material installation techniques
- Reading blueprints and specifications
- OSHA safety regulations and fall protection
- Leak detection and waterproofing techniques
Step 4: Get Certified and Licensed
OSHA Certification
Safety is paramount in commercial roofing. New Jersey mandates that all roofers complete OSHA (Occupational Safety and Health Administration) safety training. OSHA 10 or OSHA 30 certifications are standard requirements for most employers.
State Licensing Requirements
New Jersey requires roofing contractors to register with the New Jersey Division of Consumer Affairs. If you plan to start your own roofing business, you may also need a Home Improvement Contractor (HIC) license.
Step 5: Build Your Skills and Specializations
The more specialized skills you acquire, the higher your earning potential. Consider additional certifications like:
- NRCA ProCertification – Recognized by the National Roofing Contractors Association.
- Certified Green Roofer – Ideal for eco-friendly commercial projects.
