Flat roofs fail at the details. So we obsess over the details.
Vancouver Specials, carports, additions, sundecks: low-slope roofs live and die by seam quality, drainage and parapet flashings. We build two-ply Soprema systems the way the manufacturer specifies.
Why two-ply torch-on, not rolled asphalt.
SBS-modified two-ply membranes are the coastal BC standard for a reason:
- Redundancy. Two independent waterproofing layers. A puncture in one rarely becomes a leak through both.
- Flexes with weather. Modified bitumen handles our freeze-thaw swings without cracking like old built-up roofs.
- Heat-welded seams. Torched seams fuse into one membrane; there's no adhesive joint to let go in year eight.
- Walkable finishes. Granulated cap sheets and walkway pads handle foot traffic on decks and over-garage access.
Low-slope projects we do every month.
Vancouver Specials
The classic low-slope family home. Full re-membrane with new insulation board where needed and properly sloped drainage to scuppers or gutters.
Additions & Carports
Tying new flat sections into existing shingle or membrane walls is flashing work first, membrane second. It's where most other contractors' leaks start.
Sundecks & Balconies
Torch-on deck systems with walkable finish and proper slope to drains, integrated with doors and railings so water stays outside the envelope.
Garages & Laneway Homes
Over-structure roofs where height is tight and every millimetre of assembly counts.
Repairs & Re-Seams
Patching older torch-on with compatible Soprema materials so patches bond instead of peeling off in three winters.
Capped Composite Conversions
When a deck membrane is beyond saving, we rebuild the assembly and hand back a surface ready for new decking above it.
A flat roof's real job is moving water.
Every flat roof we build starts with the question "where does the water go?" Positive slope to drains, scuppers or overflow paths comes before any membrane is lit. Ponding water cuts membrane life roughly in half, which is why we re-slope with tapered insulation rather than membrane over puddles.
- Drains, scuppers and overflow routes verified and kept clear
- Tapered insulation where framing can't provide slope
- Parapet and wall terminations sealed under metal counterflashings
