How Much Does Commercial Roofing Cost?
Commercial roofing costs vary depending on the roofing system, building size, roof accessibility, and project complexity. Flat roofing systems such as TPO and EPDM are generally priced per square foot, while metal roofing and specialty systems require customised estimates. Most commercial roofing projects range between $4 and $15 per square foot, depending on the roofing material and installation requirements. Larger buildings often benefit from lower installation costs per square foot, while complex roof designs or structural repairs can increase the overall investment. The best way to determine your project's cost is through a professional roof inspection. Roofing Relief Pros provides free, no-obligation estimates tailored to your building and roofing requirements.
Average Commercial Roofing Costs by Roofing System
Different roofing systems offer unique advantages in durability, energy efficiency, and maintenance requirements.
| Commercial Roofing System | Average Installed Cost |
|---|---|
| TPO Roofing | $4–$8 per sq. ft. |
| EPDM Roofing | $4–$8 per sq. ft. |
| PVC Roofing | $6–$12 per sq. ft. |
| Modified Bitumen | $4–$9 per sq. ft. |
| Built-Up Roofing (BUR) | $5–$10 per sq. ft. |
| Metal Commercial Roofing | $8–$16 per sq. ft. |
TPO and EPDM remain popular choices for flat commercial roofs due to their affordability and energy efficiency. PVC roofing offers superior chemical resistance, while metal roofing provides exceptional longevity and durability for commercial properties.
Commercial Roofing Cost by Building Size
Building size significantly affects the total project cost because larger roofs require more materials, labour, and installation time.
| Building Size | Estimated Cost |
|---|---|
| 5,000 sq. ft. | $20,000–$40,000 |
| 10,000 sq. ft. | $40,000–$80,000 |
| 20,000 sq. ft. | $80,000–$160,000 |
| 30,000 sq. ft. | $120,000–$240,000 |
| 50,000 sq. ft. | $200,000–$400,000 |
These estimates are intended as general pricing guides. The final cost depends on the roofing system selected, insulation requirements, roof accessibility, and any repairs required before installation.
Commercial Roofing Cost by Project Type
Commercial roofing costs also depend on the scope of work being completed.
| Project Type | Average Cost |
|---|---|
| New Commercial Roof Installation | $4–$15 per sq. ft. |
| Commercial Roof Replacement | $5–$16 per sq. ft. |
| Commercial Roof Repair | $400–$5,000+ |
| Roof Coating Application | $2–$5 per sq. ft. |
| Commercial Roof Inspection | FREE with Roofing Relief Pros |
| Preventive Roof Maintenance | $500–$2,500 annually |
Roof replacements and new installations generally require the largest investment, while roof coatings and preventive maintenance offer cost-effective ways to extend the life of an existing commercial roof.
Factors That Affect Commercial Roofing Costs
Several factors influence the final cost of a commercial roofing project. Roofing Relief Pros provides comprehensive inspections and transparent written estimates, ensuring commercial property owners understand every aspect of their roofing investment before work begins.
Roof Size
Larger commercial buildings require more roofing materials, labour, and installation time.
Roofing System
TPO, EPDM, PVC, metal, and modified bitumen each have different material and installation costs.
Building Accessibility
Multi-story buildings, restricted access, and occupied facilities can increase labour requirements.
Insulation & Roof Deck Condition
Damaged roof decking or insulation may need replacement before the new roofing system can be installed.
Drainage & Roof Design
Roof penetrations, HVAC units, skylights, drainage systems, and complex layouts can increase installation time and project costs.
Project Scope
Whether you need a new installation, replacement, repair, coating, or ongoing maintenance will significantly influence the overall investment.
What's Included in a Commercial Roofing Project?
Every commercial roofing project is tailored to the building’s condition, roofing system, and business requirements. A professional roofing contractor begins with a detailed inspection to evaluate the roof, identify existing issues, and recommend the most cost-effective solution.
A typical commercial roofing project may include:
- Comprehensive roof inspection
- Removal of damaged roofing materials (if required)
- Roof deck evaluation
- Insulation replacement or upgrades
- Installation of the selected roofing system
- Flashing and drainage improvements
