Commercial Flat Roof Cost in Dallas–Fort Worth
What replacing or restoring a flat, low-slope commercial roof costs by system.
In Dallas–Fort Worth, replacing a commercial flat (low-slope) roof runs about $4–$15 per square foot installed depending on the system — EPDM at the low end, TPO and modified bitumen in the middle, PVC higher — with tear-off, insulation and roof access moving the number. A restoration coating, where the roof qualifies, costs 40–60% less than a full replacement, and targeted repairs are priced by scope.

What drives flat roof cost
- System choice — EPDM vs. TPO vs. PVC vs. modified bitumen
- Tear-off vs. recover — removing old layers adds cost
- Insulation — R-value and tapered systems to correct ponding
- Size & access — roof height, staging and equipment
- Penetrations — HVAC curbs, drains and skylights to flash
