Pro Torch Roofing replaced the flat roof on a commercial retail building in the Brentwood area of Burnaby with a 2-ply SBS torch-on membrane. Tear-off was done in sections and tied in each day so stores and restaurants below stayed open throughout, and rooftop HVAC units were flashed in place. Expected service life: 25–30 years.
The challenge
A leaking roof over a restaurant is an emergency for the tenant and a liability for the landlord. This building had multiple tenants with different hours, rooftop HVAC units serving each unit, and a roof that had been patched so many times the original membrane was hard to find. The owner needed a permanent fix without a single tenant losing a day of trade.
What we did
Phasing around tenants
We mapped the roof to the tenant spaces below and worked section by section, with noisy tear-off done before opening hours and each day's section fully torched in and watertight by close. Kitchen exhausts and make-up air units stayed running.
HVAC and penetrations
Every curb and pipe was stripped in with reinforced base-sheet flashing before the cap sheet, and units that could not be lifted were re-flashed in place with new custom metal counter-flashings. Old abandoned penetrations were removed and decked over rather than patched.
2-ply SBS torch-on
Torch-applied SBS base sheet and granulated cap sheet across the full field, laps torched and probed, drains re-flashed, with a hot-work plan and fire watch each shift under our $5M hot-work policy.
The result
One continuous roof instead of a patchwork, no tenant downtime, and a photo record and warranty the owner can hand to a future buyer or property manager.

Questions about commercial roofing in Burnaby
Can you replace a roof over open stores and restaurants?
Yes. We phase the roof to match the tenant spaces, do loud work outside opening hours and close every section before the end of the shift.
What does a commercial torch-on roof cost in Burnaby?
Pro Torch Roofing installs 2-ply SBS torch-on at $10–$20 per square foot. Roofs crowded with HVAC and kitchen exhausts cost more because of the detailing around each unit.
Do the HVAC units have to be removed?
Usually not. We flash around units in place with reinforced membrane and new counter-flashings; only units on rotted curbs need to be lifted.
Can you just patch it again?
We can, and we offer honest repairs, but a roof that has been patched repeatedly is telling you the membrane has reached end of life. Replacement is cheaper than the next five emergency calls.
