Roofing Giant · Free tool
A planning range for a commercial roof in Dallas–Fort Worth. Enter the roof area, the system you are considering, whether the existing roof is torn off or recovered, and the insulation approach. The estimator applies 2026 DFW per-square-foot ranges and shows how the cost splits.
Tool context: this estimator provides a planning range, not a commercial proposal. Continue with Commercial Roofing, the DFW Roofing Comparison Center, and all Roofing Giant tools.
What moves a commercial roof price
Tear-off vs recover
A recover may be permitted on some buildings when the existing assembly, number of roof layers, moisture condition, adopted code and manufacturer requirements allow it. Moisture investigation and deck/assembly condition help determine whether recover is appropriate.
Insulation and energy code
Required roof-insulation values depend on the locally adopted energy code, building type and project scope. Added or tapered insulation can materially change cost and may be used to improve drainage where the roof design supports it.
Details and equipment
Parapets, curbs, drains, HVAC units and penetrations are where labor goes; two buildings with the same area can differ by half.
Warranty level
Longer or no-dollar-limit manufacturer warranties can require specified membrane thickness, approved components, contractor eligibility, manufacturer inspections and ongoing maintenance. Compare the current written warranty requirements for the exact system being proposed.
Restoration instead
A silicone or acrylic coating over a sound roof costs $2 to $4 per square foot and adds 10 to 20 years.
Access and schedule
Occupied buildings, night work and crane lifts add cost; a clear staging area saves it.
