Flat Roof Replacement in Toronto by Expert Flat Roofers
We specialize in Toronto flat roof replacement projects using hot asphalt Built-Up Roof systems, built layer by layer by hand and designed to fit your building perfectly. 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 48 years of experience, our flat roofing specialists deliver tried, tested, and trusted commercial roofing solutions.

Flat Roof Replacement Backed by Transparency and Integrity
Can you install a new B.U.R. over the top of your existing roof (Overlay)?
– You can, but the question is, should you?
As a flat roof specialist that Toronto property owners trust, we follow strict standards. It is our company policy, as certified roofing contractors, not to install a new B.U.R. 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 — you end up back where you started. That's why we focus on protecting your investment and keeping your roof solid long-term by following practices that actually work and give you real peace of mind.

Commercial Roofing Replacement: Methods, Materials, and Project Steps
When you're planning a commercial roof renovation, you need to take a look at how your current flat roof structure is holding up and decide on the best replacement method. Whether you go with full removal and replacement or decide on an overlay, getting a proper assessment with thermal imaging and moisture detection is key to making sure everything performs well long-term, saves you energy, and stays safe.
Based on what your building needs, different flat roofing materials might work best including Built-Up Roofing (BUR) systems with hot asphalt and gravel, PVC membranes, or cold-applied liquid systems.
Comprehensive commercial roofing replacement typically involves:
-
Complete tear-off versus overlay – we'll weigh the pros and cons based on your roof's age, damage level, and what your warranty requires
-
Deck inspection and structural repairs to get your roof foundation solid again
-
Insulation upgrades to boost energy efficiency and bump up your building's R-value
-
Installing vapour barriers and moisture control layers for protection that actually lasts
-
Adding reflective roof coatings to cut down on heat buildup and help your system last longer
Following proper safety measures throughout the entire replacement process:
-
Careful membrane installation using torch-on, mechanically fastened, or adhered methods – whatever works best for your situation
-
Final cleanup and flashing work to make sure your entire system is watertight and built to last
