Flat roof replacement costs in Mississauga
Mississauga shares Toronto's climate challenges — freeze-thaw cycles, winter snow loads, and summer heat — but offers slightly better contractor access and pricing due to its suburban layout. The city's massive commercial and industrial footprint makes flat roof replacement a constant need. TPO is increasingly popular for Mississauga's commercial buildings.
| Material | Cost / sq ft | Lifespan |
|---|---|---|
| Modified bitumen | $9–$15 | 15–25 yrs |
| EPDM (rubber) | $9–$17 | 20–30 yrs |
| TPO | $11–$19 | 20–30 yrs |
| PVC | $13–$23 | 25–35 yrs |
| Built-up (BUR) | $10–$16 | 20–30 yrs |
