Roof Systems
Decades of installation in Ontario's harsh climate (deep snow loads, severe freeze-thaw cycles and intense summer UV) shape how we match a system to your building. Here's our practical, field-tested take on the four flat-roof systems we work with most.
Compare the options
There's no single "best" flat roof, only the best fit for your building, budget and how the roof gets used. What each one is genuinely good and bad at:
Outstanding reflective "cool roof" capability that dramatically lowers summer cooling costs. Highly resistant to chemical exposure and punctures, ideal for modern logistics hubs and retail plazas.
Highly flexible; naturally handles Ontario's extreme temperature swings without cracking. Its dark surface absorbs significant summer heat, and the glued seams need regular checkups as they age.
An ultra-rugged, thick multi-layer system with excellent puncture resistance for foot traffic and heavy maintenance environments. Stands up superbly to thick ice and snow, but takes longer to install.
The classic multi-layer hot-tar-and-gravel system, exceptionally durable and redundant. It is heavy, has a long install timeline, and lacks the modern thermal efficiency of single-ply membranes.
Our long-standing field success is backed by top-tier manufacturer training, letting us issue full system manufacturer warranties on every project we complete.
Not sure which fits?

Roof systems
They are different single-ply and multi-ply approaches with different strengths: reflectivity, puncture resistance, ease of detailing around complex rooftops, and behaviour in Ontario's freeze-thaw cycle. The right one depends on your building rather than on the product.
Service life depends far more on installation quality, detailing and maintenance than on the membrane type. A well-detailed and maintained roof routinely outlasts a better-specified one that nobody looks at.
Usually yes, and a re-roof is the natural moment to reconsider. The existing deck, insulation, rooftop equipment and drainage all influence what is sensible.
One that details well around penetrations and curbs, since that is where leaks start. We recommend based on how complex your roof actually is, not just its square footage.
