Flat Roof Repair · Richmond, BC
Flat roof repair in Richmond: membranes, seams and drains
Flat and low-slope roofs are common on Richmond townhouses, condos, garages and additions. They drain slowly, so small flaws let water in during the long wet season. Repair depends on the membrane type. Providers commonly work with systems such as SBS torch-on, EPDM and TPO. This page explains the signs, the steps and what to ask.
What to look for
Signs you may need flat roof repair.
- Ponding water that remains 48 hours after rain
- Blisters, cracks or splits in the membrane
- Open or lifted seams along edges and penetrations
- Granule loss or exposed fabric on torch-on roofs
- Stains on ceilings below a flat section
- Gravel or ballast displaced, exposing the surface
What to expect
What good flat roof repair looks like.
The repair should match the existing membrane. A torch-on SBS roof, an EPDM sheet and a TPO membrane each need different materials and methods. Ask the provider which system you have and how the patch will be bonded or welded.
Seams, drains, edges and penetrations are the usual failure points. A provider should check them, test or probe for wet insulation and repair at the cause. Ponding may point to drainage or deck problems that a surface patch will not solve.
Torch-on work involves an open flame, so ask about fire safety practices. If the membrane is widely worn, a provider may recommend recoating or replacement instead of repeated patching. Ask for both options in writing.

FAQ
Flat Roof Repair questions.
Which flat roof systems are used in Richmond?
Providers commonly mention SBS torch-on, EPDM and TPO, and older roofs may be tar and gravel. The right repair depends on which one you have, so ask the provider to identify it.
How long does a flat roof last?
It depends on the system, installation, drainage and upkeep, so we don't give a single figure. Ask the provider about expected life for your membrane and what maintenance helps.
Is ponding water on a flat roof a problem?
Standing water that stays for days stresses the membrane and seams and may signal a drainage or deck issue. A provider can tell whether it needs drainage work or only a seam repair.
Is torch-on roofing a fire risk?
Torch-on application uses an open flame, so fire safety matters. Ask the provider about their procedures, fire extinguishers and post-work checks, and confirm their insurance.
