Flat roofs are common in Toronto’s urban core, especially for commercial buildings and modern residential additions. These roofs require specialized knowledge because water does not run off them naturally—it must be expertly managed.
Common Flat Roof Issues We Fix:
Ponding Water: If water sits on your roof for more than 48 hours, it can lead to structural damage. We create proper “tapered” drainage systems to move water to the drains.
Blistering & Bubbling: Heat can cause trapped moisture to expand. We cut out and patch these sections to restore the roof’s integrity.
Flashing Failure: Most flat roof leaks occur at the edges or around vents. We use professional-grade sealants and metal flashing to secure these zones.
Our Flat Roofing Systems:
Modified Bitumen (2-Ply): A durable, multi-layer system that is excellent for high-traffic flat roofs.
EPDM / Rubber Roofing: Known for its incredible longevity and resistance to UV rays and extreme cold.
TPO & PVC: Modern, energy-efficient “cool roofs” that reflect sunlight and help lower your building’s cooling costs
