Commercial & Industrial Roofing in Yellowknife & the NWT
When a commercial roof fails in the North, the cost isn’t just repairs — it’s downtime, inventory, and safety. Since 1984, Unico Contractors has protected the buildings that keep Yellowknife and the Northwest Territories running: warehouses, retail, government, institutional and industrial facilities built to survive an Arctic climate.
Commercial roofing systems we install
- Flat & low-slope roofing — built-up and modified bitumen systems
- Torch-on (SBS) membrane roofing — our specialty for Northern conditions (we carry a $2M liability policy with an open-flame rider — most contractors don’t)
- Single-ply membrane systems
- Metal roofing — durable, snow-shedding, built for the Arctic
- Roof surveys, condition reports & preventative maintenance programs
