4

Ice & Water Protection

5

Shingle Installation

We use high-wind rated shingles suitable for Grimsby's lakefront conditions, installed with additional fasteners to withstand gusts off Lake Ontario. Our installation methods account for both winter snow loads and summer heat exposure typical in the region.

6

Ventilation & Ridge Cap

Proper ventilation is crucial in Grimsby's humid lakeside climate. We install ridge vents and soffit systems designed to manage moisture from lake effect weather while ensuring adequate airflow throughout all seasons, particularly during humid summers.

How We Protect Grimsby Roofs from Ontario's Extreme Weather

From lake-effect snow to summer heat waves, Grimsby roofs face unique challenges. Here's how we engineer protection.

3D Attic Ventilation System with Airflow

Balanced attic ventilation prevents ice dams, extends roof life, and reduces energy costs

Ice Dam Prevention

The Challenge:

Grimsby's position near Lake Ontario creates frequent freeze-thaw cycles, leading to significant ice dam risks. The average 100cm annual snowfall, combined with lake-effect weather patterns, increases the likelihood of ice formation along roof edges.

Our Solution:

We implement a comprehensive ice dam prevention system including enhanced insulation, proper attic ventilation, and premium ice and water shield extending 6 feet up from all eaves. This system is specifically designed for Grimsby's lake-effect snow conditions.

High Wind Protection

The Challenge:

Grimsby experiences strong winds off Lake Ontario, particularly during winter storms and seasonal transitions. The escarpment geography can funnel and intensify these winds, creating additional stress on roofing systems.

Our Solution:

Our installations use six-nail patterns with high-wind rated shingles tested for 130mph winds. We pay special attention to starter strips and ridge caps, using enhanced securing methods for homes in exposed areas near the lake or escarpment.

Extreme Temperature Swings

The Challenge:

Grimsby faces temperature swings from -20°C in winter to 30°C+ in summer. These extremes, combined with lake-effect weather, can cause significant expansion and contraction of roofing materials.

Our Solution:

We select temperature-resistant materials rated for extreme conditions and install with proper spacing to allow for thermal movement. Our ventilation systems are optimized for both summer heat dissipation and winter moisture control.

Moisture & Humidity

The Challenge:

The proximity to Lake Ontario creates high humidity levels in Grimsby, while the escarpment can trap moisture. This combination leads to increased risk of mold, rot, and premature shingle deterioration.

Our Solution:

Our roofing systems incorporate moisture-resistant underlayment, enhanced ventilation systems, and proper drainage designs. We use specialized algae-resistant shingles and ensure adequate attic ventilation to combat Grimsby's unique humidity challenges.

Ironclad Warranties

Comprehensive Protection

Every roof installation includes dual warranty coverage: our lifetime workmanship guarantee plus manufacturer product warranties registered in your name.
