The cost of commercial roofing in Delta, BC, varies depending on the specific material chosen for the project. Based on data provided by Paragon Roofing BC, the estimated costs per square foot for common commercial roofing systems are as follows:
Torch-On Modified Bitumen: This is the most budget-friendly option, ranging from $7 to $11 per square foot. It is highly effective for low-slope roofs due to its multi-layer waterproofing.
TPO (Thermoplastic Polyolefin): This popular choice for flat roofs costs between $8 and $12 per square foot and offers excellent puncture and UV resistance.
Metal Roofing: While it requires a higher initial investment of $10 to $16 per square foot, it provides superior longevity (40+ years) and high wind resistance.
Additional factors that may influence the final project cost include requirements for meeting RCABC technical standards, municipal permit fees, and the need for specialized maintenance or repairs to handle Delta’s heavy annual rainfall and coastal winds.
