Commercial roof cost depends on four things: roof size, complexity and penetrations, the roof’s condition, and the system and warranty selected. For aging roofs, compare full restoration with a full tear-off and replacement before deciding. Repairs are priced after an onsite assessment.
Nobody likes a roofer who answers “how much?” with “it depends.” It does depend, but not on mystery. Here is what moves the number, and how to get a useful first range for your building.
What moves the price
- Roof size. Larger roofs spread setup costs but need more material and labor.
- Complexity and penetrations. HVAC curbs, pipes, drains, parapets and roof levels all add detail work.
- Roof condition. Wet insulation, deck damage, blisters and failed seams must be addressed, and can rule restoration out.
- System and warranty selection. Different systems and warranty terms require different builds and inspections.
- Access and logistics. High parapets, cranes, staging and occupied buildings change how work is scheduled.
- Code requirements. A full replacement can trigger current energy-code insulation requirements.
Restoration vs full tear-off
For an aging roof, the two big options are a full roof restoration or a full tear-off down to the deck and replacement. Start with a free Roof Scan for an estimate on your building.
Estimates are preliminary ranges, not a quote or guarantee. Final recommendations and pricing require an onsite assessment and confirmation of roof conditions.
Service calls and repairs
- $1,125 minimum service call: two technicians, first three hours, port-to-port.
- $250 per hour for the whole crew after that.
- $300 emergency fee for active leaks or priority dispatch.
- $500 after-hours fee after 5 PM weekdays and on weekends.
- The repair itself is scoped and priced after the onsite assessment.
- Nothing above $2,500, or a lower limit you set, without your approval.
Quick answers
How much does a commercial roof restoration or replacement cost?
It depends on roof size, complexity and penetrations, the roof’s condition, and the system and warranty selected. Our free Roof Scan gives an estimate for your building from aerial imagery. Final pricing requires an onsite assessment.
How much does a commercial roof repair cost?
The repair itself is scoped and priced after an onsite assessment. Getting a two-technician crew to the roof follows our service-call rates: a $1,125 minimum for the first three hours, port-to-port, then $250 per hour for the crew. Emergency dispatch adds $300 and after-hours work adds $500.
Why do commercial roofing quotes vary so much?
Tear-off scope, wet insulation, insulation code requirements, roof access, rooftop equipment, flashing details and warranty length all move the price. Compare bids line by line, not just by the total.
Is a blanket price per square foot useful?
Only as a very rough starting point. Two roofs of the same size can differ widely in condition and detail work, which is why we provide preliminary ranges and confirm pricing onsite.
