Flat Roof Replacement

We specialize in hot asphalt Built-Up Roof replacements, handcrafted layer by layer, designed to fit your building like a glove. It is the 'Cadillac' of roof systems for Canadian winters. Only hot asphalt roof systems have a self-healing quality. After a harsh winter, your roof may develop fractures or tiny fissures. When the temperature heats up in the summer, this asphalt starts to melt and self-heal. That is why, with 47 years of experience, our roof replacements are tried, tested, and true. 


8 - 15

We feel confident in our up to 15-year workmanship warranty, backed directly by our company. We install many different types of roof systems and variations and can tailor the perfect full or partial replacement to meet your building's requirements and budget.

Transparency & Integrity

Can you install a new flat roof over the top of your existing roof (Overlay)?  - You can, but the question is, should you?

Please note that it is our company policy not to install a new roof system over the top (Overlay) of an existing one. Once the top roofing layer starts to prematurely fail, repairing leaks becomes very costly and without warranty due to multiple roof layers. Ultimately, the removal of all roof layers becomes inevitable, bringing you right back to square one, therefore, we prioritize your investment, and the long-term integrity and durability of your new roof system by adhering to this policy.
