To Seal & Protect
We specialize in replacing flat roof Toronto 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 flat roof may develop fractures or tiny fissures from seasonal roofing damage. 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.
8 - 15 Years
We feel confident in our up to 15-year workmanship warranty, backed directly by our company. Our team of flat roof specialists installs different roof system options and can tailor the right full or partial replacement to fit your building's needs and budget. We've built a solid reputation in commercial roofing, and we make sure you get results that last.

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 that Toronto property owners trust, we follow strict standards. It is our company policy, as certified flat roofing contractors, not to install a new B.U.R. system over an existing one. Once the upper layer begins to fail, often due to seasonal roofing damage, 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.
