How Much Does Commercial Roofing Cost?
Commercial roofing typically costs $4 to $12 per square foot for full replacement depending on roof type, deck condition, and access. Repairs vary widely from $500 to $5,000+ depending on leak severity and affected area.
#
What Affects Commercial Roofing Cost
Roof type determines material cost. TPO and EPDM are common and moderate in cost. Metal roofing runs higher. Built-up (BUR) and modified bitumen fall in between.
Square footage is the base multiplier. Larger roofs have more material but may have slightly lower per-sqft costs due to scale.
Tear-off requirements add significant cost. Removing existing membrane, insulation, and flashing can add $1-3/sqft to the job.
Insulation and drainage may need upgrade if current R-values are substandard or if ponding is an issue.
Penetrations (HVAC curbs, vents, skylights, pipes) require flashing work. More penetrations mean more labor and failure points.
Access and safety add cost for steep slopes, limited access, or occupied buildings requiring containment and timing coordination.
#
Repair vs. Replacement
Repairs make sense for localized issues on younger roofs. Replacement makes sense when leaks are widespread, membrane is past useful life (15-25 years depending on type), or repeated repairs keep failing.
A good roofing contractor will present both options with honest trade-offs.
