Why Choose Red Maple for Flat Roof Repair & Torch-On Roofing?
Flat and low-slope sections are common on Vancouver Specials, additions, carports and modern homes across Metro Vancouver. Asphalt shingles are not designed for very low slopes, so these areas need a membrane. Two-ply SBS modified bitumen torch-on is the system we install: a base sheet plus a granulated cap sheet heat-welded together into one continuous waterproof layer.
Most flat roof leaks we see start at the edges and penetrations (drains, scuppers, vent pipes, wall flashings) or where water ponds. A good repair fixes the detail that failed and, where possible, the drainage that caused it.
How We Work
Inspect Deck & Drainage
We check the existing membrane, deck condition and how water drains, including drains and scuppers.
Prepare the Substrate
Old membrane removed where replacing; damaged decking replaced; slope and drains corrected where possible.
Base & Cap Sheets
SBS base sheet installed, then the granulated cap sheet torch-welded over it with overlapping seams.
Flash Every Detail
Edges, walls, drains, scuppers and pipe penetrations flashed with compatible membrane.

Torch-On Roof Repair
Small splits, open seams and failed flashings on an otherwise sound membrane can often be repaired with new torch-on material welded over the area, rather than replacing the whole roof.
Residential Flat Roof Replacement
When the membrane is brittle, blistered across large areas or has been patched many times, replacement with a new two-ply system is usually the better long-term choice.
Flat Roof Leak Repair
We trace flat roof leaks to the failed detail, which is often a drain, scupper or wall flashing, and repair that point properly.
Our honest advice
If a repair will buy you several good years, we will quote the repair first.
