Flat Roof Replacement in Toronto by Expert Flat Roofers
We specialise in flat roof replacement Toronto projects using hot asphalt Built-Up Roof systems, handcrafted layer by layer, designed to fit your building like a glove. It’s the 'Cadillac' of roof system durability for Canadian winters. Only hot asphalt systems offer a self-healing quality—after a harsh winter, your roof may develop fractures or tiny fissures. When temperatures rise in the summer, the asphalt melts and self-heals. That’s why, with 47 years of experience, our flat roof specialists deliver tried, tested, and trusted commercial roofing solutions.

Flat Roof Replacement Backed by Transparency and Integrity
Can you install a new flat roof over the top of your existing roof (Overlay)?
– You can, but the question is, should you?
As a flat roof specialist Toronto property owners trust, we follow strict standards. It is our company policy, as certified roofing contractors, not to install a new roof system over an existing one. Once the upper layer begins to fail, multi-layer roof issues can make leak repairs extremely costly and ineligible for warranty coverage. Eventually, full removal becomes unavoidable, taking you back to square one. That’s why we prioritise your investment and long-term roof integrity by following best practices that ensure durability and peace of mind.

Commercial Roofing Replacement: Methods, Materials, and Project Phases
When planning a commercial roof renovation, it’s important to evaluate the condition of the existing flat roof structure and choose the most effective replacement method. Whether you decide to remove and replace a flat system or opt for an overlay, a proper assessment using thermal imaging inspections and moisture detection techniques is essential to ensure long-term performance, energy efficiency, and safety.
​
Depending on the building’s requirements, a variety of flat roofing materials may be used—including Built-Up Roofing (BUR) systems with hot asphalt and gravel, PVC membranes, or cold-applied liquid systems.
​
Here’s what a comprehensive commercial roofing replacement typically involves:
​

Deck inspection and structural repairs to restore roof stability

Upgrading insulation to improve energy efficiency and boost the building’s R-value
-
Installing vapour barriers and moisture control layers for long-term protection
