Commercial Roof Replacement
A new roof without shutting you down
We’ve roofed several buildings at Canada’s Wonderland in Vaughan with Rutherford Contracting, working around a park that stays open.
We plan tear-off in sections so the building stays dry each night, keep the site safe for staff and customers, and choose the system that suits the roof: modified bitumen, metal or shingles.
- Phased tear-off, dry every night
- Modified bitumen, metal or shingle systems
- Insulation and drainage improvements
- Clean, safe work area
Know the signs
When replacement makes sense
Call us if you notice any of these. Catching it early usually means a smaller bill.
- Leaks in several areas at once
- Wet insulation under the membrane
- Membrane or panels at end of life
- Repairs costing more every year
- Planned building upgrades
