From lake-effect snow to summer heat waves, Ancaster 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:
Ancaster experiences heavy snowfall averaging 100cm annually, with frequent freeze-thaw cycles due to its location near the Niagara Escarpment. This creates perfect conditions for ice dam formation, particularly on older heritage homes with less insulation.
Our Solution:
We implement a comprehensive ice dam prevention system including enhanced attic insulation, proper ventilation, and premium ice and water shield extending well beyond minimum requirements. Heat trace systems are installed where necessary in problem areas.
The Challenge:
Ancaster's elevation and proximity to the Niagara Escarpment expose homes to stronger wind conditions than surrounding areas. Winter storms can bring gusts exceeding 100 km/h, particularly affecting homes on exposed lots.
Our Solution:
Our installations use enhanced wind resistance techniques including six-nail patterns, upgraded starter strips, and specialized high-wind rated shingles. We pay special attention to ridge caps and edge areas most vulnerable to wind damage.
The Challenge:
Ancaster experiences extreme temperature fluctuations, from summer highs above 30°C to winter lows below -20°C. This thermal cycling puts significant stress on roofing materials and can accelerate wear on traditional installations.
Our Solution:
We use temperature-resistant materials specifically rated for Southern Ontario's climate extremes. Our ventilation systems are designed to minimize temperature differential between attic and outdoor air, reducing thermal stress on roofing components.
The Challenge:
High humidity levels in Ancaster summers, combined with significant rainfall and snow melt, create persistent moisture challenges. Many local homes show signs of inadequate moisture management in attic spaces.
Our Solution:
Our roofing system includes enhanced moisture barriers, proper attic ventilation calculated for local humidity levels, and strategic placement of vapor barriers. We ensure all penetrations are properly sealed against Ancaster's wet conditions.
