Flat Roof Services in Toronto — Every System, Every Problem
Repair, replacement, leak detection, installation, restoration, and inspection — flat roofs exclusively, diagnosed with instruments, verified by independent inspection before you pay.
Six services. One discipline: flat roofs.
Every service below starts the same way — with an instrumented diagnosis, not a guess. Thermal scanning, smoke screen detection, and controlled water testing find the actual problem, so you only ever pay for the fix your roof genuinely needs.
Flat Roof Repair
Root-cause repairs of membranes, seams, flashings, blisters, punctures, and drains across Toronto and the GTA — not patches over symptoms. Every repair is guided by thermographic inspection and water-tested before we leave, so the leak that's fixed stays fixed.
- Active leaks, ceiling stains, damaged seams or flashing
- Membrane punctures, blisters, and localized wear
- Repairs that extend roof life instead of forcing replacement
Flat Roof Replacement
Full tear-off and rebuild with corrected slope and drainage — machine-assisted cutting through any number of layers, wheeled-trailer disposal that protects your driveway, and most projects completed in one to three days. Replacement is recommended only when diagnostics prove the system is genuinely beyond repair.
- Roofs at end of life with widespread saturation
- Chronic ponding needing re-sloping and tapered insulation
- Two-ply SBS, TPO, EPDM, or PVC — specified on evidence
Flat Roof Leak Detection
On a flat roof, water travels metres from where it enters — which is why guesswork fails. Infrared thermal scanning, smoke screen detection, and controlled water testing pinpoint the true entry point, and settle the question most roofers never ask: is it a leak, condensation, or ponding? Often the honest answer saves you a full replacement.
- Mystery leaks other roofers couldn't solve
- Winter stains that might be condensation, not a leak
- Pre-repair diagnosis that prevents wasted spending
Flat Roof Installation
New flat roof systems for custom builds, additions, laneway houses, and commercial construction — with drainage engineered from day one. Over 1,000 roofs installed across the GTA in every membrane system, each qualifying for full manufacturer warranties through our certified-installer status.
- New construction, additions, and conversions
- Laneway and garden suites with rooftop potential
- Commercial decks engineered for equipment and traffic
Flat Roof Restoration
Reinforcement coatings and restoration systems that add 10–15 years of life at a fraction of replacement cost — when diagnostics confirm the roof underneath is sound. A restored roof also reflects heat, cutting summer cooling loads on Toronto buildings.
- Aging but structurally sound membranes
- Budget-conscious owners deferring replacement wisely
- Commercial roofs needing energy-efficient reflective coatings
Flat Roof Inspection
Instrumented inspections with full photo documentation — for maintenance planning, pre-purchase due diligence, and insurance claims. Our written reports include thermal findings and moisture mapping, and for insured losses, a cause-of-loss determination adjusters accept. The first report is everything.
- Pre-purchase inspections with documented findings
- Insurance claims needing adjuster-ready evidence
- Annual maintenance inspections that prevent surprises
We install and service all flat roof systems.
Recommended on evidence, never inventory — the right system depends on your building, budget, and how the roof will be used.
Two-Ply SBS Modified Bitumen
Toronto's workhorse — torch-applied, durable through freeze-thaw, ideal for most residential flat roofs.
TPO Membrane
Heat-welded single-ply with reflective white surface — energy-efficient choice for commercial roofs.
EPDM Rubber
Proven synthetic rubber with decades of track record — flexible, economical, fast to install.
PVC Membrane
Chemical- and grease-resistant single-ply — the standard over restaurants and mechanical areas.
Liquid-Applied & Hybrid
Seamless waterproofing for complex details, terraces, and roofs crowded with penetrations.
Tapered Insulation & Green Roof
Engineered slope packages that end ponding, and waterproofing assemblies for green roofs.
Start from your symptom.
It might be a leak — or winter condensation, which no roof repair can fix. Start with instrumented leak detection to find the real cause before spending anything.
Leak DetectionPonding water is the number one flat roof killer, and it's a slope problem — often solved with re-sloping and tapered insulation rather than endless membrane patches.
Re-Sloping & ReplacementMaybe not. If the deck and insulation test dry, a restoration coating adds 10–15 years at a fraction of the cost. Diagnostics decide, not a sales pitch.
Restoration vs. ReplacementEmergency leak? We answer 24/7.
Rapid response across Toronto and the GTA — temporary waterproofing in any weather, including winter, followed by a proper permanent repair. Insurance documentation included.
Choosing the right service.
How do I know if I need a repair or a full replacement?
Diagnostics decide. Thermal scanning and core sampling show how much of the insulation is saturated: isolated damage gets a targeted repair; widespread saturation or a failed deck justifies replacement. We show you the evidence either way — replacement is never the default recommendation.
What does a flat roof service visit cost in Toronto?
Estimates are free. Repairs commonly run in the hundreds; full replacements typically range $10–$16 per square foot depending on size, system, and insulation. Every quote is written, itemized, and based on an on-site diagnostic.
Which flat roof system is best for Toronto's climate?
For most homes, two-ply SBS modified bitumen handles freeze-thaw exceptionally well. Commercial roofs often benefit from TPO's reflectivity or PVC's chemical resistance. The honest answer depends on your building — which is why we specify from diagnostics, not inventory.
Do you handle both residential and commercial flat roofs?
Yes — from laneway houses and Toronto semis to condo decks, warehouses, and commercial plazas across the GTA. Same instruments, same pay-after-independent-inspection standard on every project.
Can one company handle diagnosis, repair, and the insurance claim?
That's exactly what we do. Instrumented first report, cause-of-loss determination, adjuster-ready documentation, then the repair itself — verified before you pay.
