From lake-effect snow to summer heat waves, Paris 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:
Paris faces significant ice dam risks due to fluctuating winter temperatures and substantial snowfall. The proximity to the Grand River increases humidity levels, making homes more susceptible to ice formation along roof edges and in valleys.
Our Solution:
We implement a comprehensive ice dam prevention system including enhanced insulation, proper ventilation, and premium ice and water shield installation extending 6 feet beyond the heated wall line. Special attention is given to problematic areas near valleys and dormers.
The Challenge:
Paris experiences strong wind patterns through the Grand River Valley, particularly during spring and fall storms. Historic homes in the downtown area are especially vulnerable to wind damage due to their age and elevated positions.
Our Solution:
Our installation includes enhanced nail patterns, starter strip reinforcement, and high-wind rated shingles. We pay special attention to ridge caps and roof edges, using additional securing methods in high-exposure areas.
The Challenge:
Paris endures significant temperature fluctuations, from summer highs above 30°C to winter lows below -20°C. These extreme variations can cause shingle expansion and contraction, potentially compromising roof integrity.
Our Solution:
We utilize temperature-resistant materials specifically rated for Southern Ontario's climate extremes. Our installation techniques account for thermal movement, and we include additional ventilation to regulate attic temperature year-round.
The Challenge:
The Grand River's proximity creates higher humidity levels in Paris, especially during spring and summer months. This moisture can lead to accelerated shingle deterioration and potential underlying deck damage.
Our Solution:
Our roofing system incorporates enhanced moisture barriers, proper ventilation sizing for Paris's humidity levels, and specialized underlayment that prevents moisture accumulation. We also install additional vents in high-moisture areas.
