Why Weatherproofing Your Barn is Critical
Ontario’s extreme seasonal changes—from freezing winters to humid summers—can wreak havoc on unprotected barns. Without proper protection, your barn’s structure and paint can deteriorate rapidly, leading to costly repairs.
This guide covers essential weatherproofing techniques to shield your barn from Ontario’s challenging climate while maintaining its appearance and structural integrity.
How Ontario’s Weather Damages Barns
1. Winter Threats: Snow, Ice, and Freeze-Thaw Cycles
- Heavy snow loads strain roofs and gutters
- Ice dams cause water seepage into walls
- Repeated freezing and thawing cracks wood and paint
2. Summer Challenges: UV Rays, Humidity, and Storms
- Sunlight fades and degrades paint
- High humidity promotes rot and mold
- High winds and rain damage loose siding and roofing
3. Year-Round Concerns
- Moisture penetration warps wood and rusts metal
- Temperature fluctuations cause expansion/contraction damage
- Pest infestations exploit weakened structures
5 Essential Weatherproofing Solutions
1. High-Quality Exterior Paint & Sealants
- Use industrial-grade polyurethane paints (10-15 year lifespan)
- Apply weather-resistant primers first
- Choose light colors to reflect UV rays in summer
2. Proper Roof Maintenance
- Inspect and repair metal roofing/seams annually
- Ensure proper slope for snow/water runoff
- Consider rust-resistant coatings for metal roofs
3. Improved Drainage & Moisture Control
- Install seamless aluminum gutters with extended downspouts
- Grade soil to direct water away from foundation
- Use vapor barriers in high-humidity areas
4. Structural Reinforcements
- Replace rotting beams and posts with pressure-treated lumber
- Add cross bracing in high-wind areas
- Install hurricane ties on roof trusses
5. Protective Coatings for Vulnerable Areas
- Apply marine-grade varnish to doors and windows
- Use rust-inhibiting paint on metal fixtures
- Treat wood with water-repellent preservatives
