We specialize in Owens Corning roofing systems, including their highly durable TruDefinition® Duration® architectural shingles. These shingles are engineered with SureNail® Technology, which enhances wind resistance—a crucial feature for Toronto’s unpredictable storms. Plus, their LayerLock™ technology ensures better shingle integrity, reducing the risk of damage during our frequent freeze-thaw cycles. For homeowners looking for a classic look with proven performance, our asphalt shingle options provide excellent value without compromising on durability or aesthetics.
One of the biggest benefits our customers appreciate is our responsiveness and reliability, especially when emergency repairs are needed. We know how damaging a leaking roof can be, particularly during Toronto’s intense spring rains or sudden summer thunderstorms. That’s why we offer emergency roofing repairs, often mobilizing our crew quickly to address leaks or storm damage before they escalate. For example, just last winter, we helped a family in High Park get their roof repaired after ice dams caused significant leaks—preventing further interior damage and costly repairs.
A quality roof is more than just shingles. Learn about the critical components that protect your Toronto home from Ontario's extreme weather.

From lake-effect snow to summer heat waves, Toronto roofs face unique challenges. Here's how we engineer protection.
Balanced attic ventilation prevents ice dams, extends roof life, and reduces energy costs
The Challenge:
Heavy snow + freeze-thaw cycles create ice dams that force water under shingles
Our Solution:
Extended ice & water shield + balanced ventilation keeps attic cold and prevents melt/refreeze
The Challenge:
Lake winds and storms can reach 80+ km/h, lifting shingles and exposing deck
Our Solution:
6-nail fastening pattern + Class F wind-rated shingles (130 MPH) + starter course
The Challenge:
-30°C winters to +35°C summers cause expansion/contraction stress
Our Solution:
Flexible synthetic underlayment + proper fastener spacing allows seasonal movement
The Challenge:
Lake-effect moisture and humid summers promote algae, moss, and rot
Our Solution:
Algae-resistant shingles + ventilation + deck moisture barriers prevent growth
