Project Overview
A 2-ply SBS torch-on replacement on a campus building at UBC in Vancouver. The work was sequenced in sections so the building stayed fully occupied, with daily tie-ins to keep every exposed area watertight overnight. Expected service life: 25–30 years.
Roofing System & Materials
- Torch-applied SBS base sheet and granulated cap sheet across the full field, all laps torched and probed
- Reinforced base-sheet flashings stripped in around every curb and penetration before the cap — three layers at the most vulnerable points
- Written hot-work plan, extinguishers at every torch, fire watch after each shift under our $5M hot-work policy
- Dated photographs of every phase and a written warranty for the owner
Challenges & Solutions
Institutional roofs are big, busy and never empty. The roof was divided into sections sized to what the crew could strip, re-sheet where needed and fully cover in one shift, and each day's work was tied into the existing membrane with a torched temporary seal before the crew left — so a surprise overnight rain never found an open deck.
