Flat & commercial roofing that handles Toronto's ponding, freeze-thaw, and rooftop traffic
From strip malls in Scarborough to warehouses in Vaughan, we install and repair membrane roofing systems built to shed water and survive an Ontario winter.

Flat and low-slope roofs across the GTA face a specific enemy: standing water after every spring melt and summer downpour, sitting on a membrane that's also expanding and contracting through freeze-thaw cycles. We spec systems and slopes to move water off, not let it sit.
TPO and membrane systems suited to the climate
We install and repair TPO, modified bitumen, and built-up roofing selected for how they perform through Ontario's temperature swings, not just upfront cost.
Drainage design that actually sheds water
Ponding is the number-one cause of premature membrane failure on flat roofs. We check slope and drain placement on every inspection, not just the membrane surface.
Rooftop equipment and penetration flashing
HVAC units, vents, and skylights are where commercial roofs fail first. We seal and flash penetrations to a standard that holds through repeated thermal cycling.
Scheduling around your business hours
For occupied commercial buildings, we plan noisy or disruptive work around your operating hours wherever possible, and keep you updated as the job progresses.
A slow flat-roof leak can sit undetected for months
Unlike a sloped residential roof, a commercial flat roof leak often travels laterally under the membrane before it ever shows up as a ceiling stain inside — by which point insulation is soaked and repair costs have multiplied.
Photo-documented inspection finds it before it spreads
We inspect membrane seams, flashing, and drainage with the same rigour whether it's a small strip-mall roof or a multi-building commercial complex, and hand you a written scope that separates urgent repairs from planned maintenance.
How we handle a commercial roofing project
Commercial work needs more coordination than a residential job — here's how we keep it organized.
- 1
Site assessment
We walk the roof, check drainage and penetrations, and photograph the membrane's actual condition.
- 2
Written scope for stakeholders
You get a clear document you can bring to property managers, boards, or ownership groups without translating a verbal estimate.
- 3
Scheduling around operations
We coordinate timing to minimize disruption to tenants or business operations.
- 4
Execution with daily updates
Photo updates and a tidy site throughout, so there's a clear record for your files.

Flat & commercial roofing questions
What flat roofing systems do you install?
We work with TPO, modified bitumen, and built-up roofing systems, selected based on the building's structure, budget, and how it needs to perform through Ontario winters.
How do you handle ponding water on an existing flat roof?
We assess slope and drainage first, since ponding is usually a drainage design issue rather than just a membrane problem, and recommend fixes in the written scope accordingly.
Can you work around tenants or business hours?
Yes, we coordinate scheduling with property managers to minimize disruption wherever the project allows.
Do you provide documentation for property management boards?
Every job includes a written scope and photo record you can present to a board or ownership group without needing to translate anything.
Do you handle rooftop HVAC and vent flashing?
Yes, penetration flashing around rooftop equipment is one of the most common failure points we inspect and repair.
