Living on the West Coast comes with incredible natural beauty, but it also brings a unique set of challenges for your roof. Constant moisture, salt air, and strong winds can take a toll on traditional roofing materials. That’s why more and more homeowners and businesses in the Comox Valley are turning to metal roofing for its durability and weather resistance.

At Aces Roofing, we know what it takes to build a roof that stands up to coastal BC conditions. Here’s how metal roofing performs in our climate—and why it might be the perfect fit for your home or commercial building.

Built for Coastal Weather

1. Outstanding Moisture Resistance
Our region sees a lot of rain, especially in the fall and winter. Metal roofing sheds water quickly and efficiently, reducing the risk of leaks, rot, and mildew. With proper installation and flashing, water simply doesn’t stand a chance.

2. Wind Resistance
High winds are common in open areas and along the coastline. Metal roofing panels—especially standing seam—are designed to lock tightly into place, resisting wind uplift far better than traditional shingles. Many metal roofing systems are rated to withstand winds of 120 km/h or more.

3. Salt Air Protection
If you’re near the ocean, salt air can accelerate corrosion in some roofing materials. High-quality metal roofs are treated with specialized coatings, like Galvalume or PVDF finishes, which protect against rust even in salty, humid environments.

4. Fire Safety
In dry summer months, fire protection becomes a concern, especially in rural and forested areas. Metal roofing is non-combustible and offers one of the highest fire ratings available, making it a safer choice in wildfire-prone zones.

Other Coastal Advantages

Energy Efficiency
Metal reflects sunlight rather than absorbing it, keeping your home cooler in the summer. Paired with proper insulation, this can help reduce energy bills year-round.

Longevity
While asphalt shingles may need replacing every 15–20 years (or sooner in damp conditions), metal roofing can last 40–70 years with minimal upkeep.

Low Maintenance
Metal roofs resist moss and algae growth—two common issues in our rainy, forested region. That means less cleaning, fewer repairs, and less hassle.

What to Watch For

While metal roofing performs exceptionally well in coastal climates, proper installation is essential. Poorly sealed fasteners, inadequate ventilation, or the wrong type of metal for your environment can reduce lifespan or lead to corrosion.

That’s why it’s important to work with a local roofing company that understands the specific demands of coastal living, like Aces Roofing.
