Flat Roofing
Flat Roofing in Nanaimo & Across Vancouver Island
Flat and low-slope roofs demand a different skill set than pitched roofing — and on rainy Vancouver Island, the margin for error is zero. Ponding water, failed seams, and flashing details are where flat roofs live or die, and Eco Roofing Ltd has the specialized experience to get every detail right.
9+ years strong
Roofing Vancouver Island homes
We install and repair single-ply membranes (TPO and EPDM) and multi-ply modified bitumen systems for residential additions, garages, and commercial buildings across Nanaimo, Parksville, Duncan, Ladysmith, and Qualicum Beach. Every flat roofing project starts with drainage: we verify slope, scuppers, and drains before recommending a membrane, because even the best material fails on a roof that cannot shed water.
From leaky carport membranes to full commercial re-roofs, our licensed crews deliver watertight, warrantied flat roofing built for 100+ inches of annual Island rainfall.

Don't ignore these
Signs You Need Flat Roofing
Spot any of these? A free inspection will tell you exactly where you stand — before a small issue becomes a big bill.
Ponding water after rain
Water standing 48+ hours after rainfall accelerates membrane breakdown and signals drainage problems.
Blisters, cracks, or seam separation
Visible membrane distress means the waterproofing layer is failing — patch now or plan replacement.
Interior stains or drips
Ceiling stains below a flat roof indicate water has already travelled through the assembly. Do not wait.
Previous patch jobs failing
Multiple old patches are a sign the membrane has reached end of life and needs professional replacement.
Why it is worth it
Why Homeowners Choose Flat Roofing
Drainage-first engineering
We correct slope and drainage issues — tapered insulation, crickets, scuppers — instead of just recovering a roof that ponds.
Heat-welded & sealed seams
TPO seams are heat-welded into a single monolithic sheet; modified bitumen is torched or self-adhered with sealed laps.
Commercial-grade materials
Quality single-ply membranes and SBS modified bitumen from established manufacturers — no bargain materials.
Penetration expertise
Vents, skylights, HVAC curbs, and parapets get custom flashing details — the leak points amateurs miss.
Minimal disruption
Most residential flat roofs complete in 1–2 days; commercial projects are phased to keep your business operating.
Maintenance programs
Annual inspection and debris-clearing plans that protect your warranty and catch small issues before they become leaks.

Good to know
Flat Roofing FAQs
A properly installed TPO or modified bitumen flat roof can last 20–30 years in our climate; EPDM typically 20–25 years. Lifespan depends heavily on drainage — roofs that pond water age much faster.
Isolated damage — a puncture, a failed seam, flashing around one vent — can usually be repaired. Widespread blistering, saturated insulation, or multiple old patches point to replacement. Our moisture survey gives you the real answer.
For residential low-slope roofs, SBS modified bitumen (torch-on) is the proven Island standard. For larger commercial roofs, TPO offers excellent seam strength and reflectivity. We recommend based on your specific building.
Absolutely — when designed for it. The keys are positive drainage (no ponding), robust flashing, and quality membranes. Our installations are engineered specifically for Island rainfall volumes.
It depends on the system, insulation needs, and access. Commercial projects are quoted per building after a site visit. Our free inspection includes an itemized written quote for your specific roof.
