What Does a Commercial Roofing Contractor Do?
A commercial roofing contractor specializes in the installation, repair, maintenance, and replacement of roofs on commercial buildings. Commercial projects differ from residential roofing projects in that the surface area is typically bigger, the materials might be more specialized, and the roof itself is usually more complicated (i.e., a flat or low-slope roofing system).
Commercial contractors are trained to work with a variety of roofing materials and systems, including:
- TPO (Thermoplastic Polyolefin)
- EPDM (Rubber Roofing)
- PVC (Polyvinyl Chloride)
- Metal roofing
- Modified bitumen
- Built-up roofing (BUR)
These professionals also handle roof inspections, leak detection, weatherproofing, insulation, and ventilation—all crucial for long-term building performance.
Key Qualities

Hiring the right commercial roofing contractor means finding someone who brings experience, reliability, and professionalism to the table. Here are some key qualities to consider:
Licensing and Insurance: Make sure the contractor is licensed to operate in your state and carries adequate liability and workers’ compensation insurance.
Commercial Experience: Residential roofing and commercial roofing can be very different. Be sure you hire a contractor who has demonstrable experience with commercial roofing jobs.
Manufacturer Certifications: Many contractors are certified by the manufacturers of the roofing materials, which can offer additional warranty options and guarantee proper installation.
Safety Standards: Roofing can be dangerous work. Reputable contractors follow OSHA regulations and invest in employee safety training.
References and Reviews: Look for contractors with strong reputations, positive reviews, and a portfolio of completed projects.
Services Offered
A full-service commercial roofing contractor typically offers:
- New roof installation for new construction or additions

- Repairing roofs due to leaks, penetrations, or storm damage
- Preventive maintenance to extend the life of the roof while minimizing disruptions

Why Hiring a Specialist Matters
Hiring a contractor who specializes in commercial roofing ensures that the job is completed according to industry standards and local building codes. Commercial roofing systems require a deeper understanding of engineering, load-bearing structures, and drainage systems. Mistakes can lead to costly problems down the road, including water damage, insulation failure, and reduced energy efficiency.

FAQ
How do I know if I need a new commercial roof or just repairs?
A professional inspection can determine whether repairs are sufficient or if a full replacement is needed. If the roof is over 20 years old and experiencing frequent issues, replacement is often the best long-term option.
How long does a commercial roof last?
Depending on the material, a commercial roof can last 20–40 years. TPO and EPDM typically last around 20–30 years, while metal roofs can exceed 40 years with proper maintenance.
Do commercial roofing contractors handle permits and inspections?
Yes, reputable contractors manage permitting and ensure the project meets all building codes and inspection requirements.
Can roofing work be done without disrupting business operations?
In many cases, yes. Contractors can work in phases, after hours, or on weekends to minimize disruption.
