Metal Roofing vs. Asphalt Shingles: What's Best for Your GTA Home?

Choosing between metal roofing and asphalt shingles is one of the most important decisions for your Greater Toronto Area home. Both materials protect against Ontario's harsh weather, but differ significantly in cost, longevity, and performance. At Seam Roofing, we install both metal roofing and asphalt shingles throughout the GTA and help homeowners choose the right option.

Understanding Metal Roofing

Metal roofing has gained popularity across the Greater Toronto Area. Modern metal roofs come in various styles, including standing seam, corrugated panels, and metal shingles. Common materials include steel, aluminum, zinc, and copper.

A properly installed metal roof typically lasts 40 years to a lifetime of the home, significantly outpacing asphalt shingles that require replacement every 15 to 30 years. This longevity appeals to homeowners planning long-term ownership.

Metal roofing excels in GTA weather. It sheds snow and ice efficiently, preventing ice dam formation common in Ontario winters. Metal also resists wind damage better than shingles and reflects solar heat, reducing cooling costs during hot summers.

The Case for Asphalt Shingles

The most popular roofing choice are asphalt shingles in Toronto and surrounding areas. They offer affordability, aesthetic variety, and proven performance. Our roofing services include architectural and premium asphalt shingles for different budgets.

The lower upfront cost makes shingles accessible to more homeowners. While metal roofing costs more, shingles provide excellent protection at a lower investment, allowing budget allocation toward other improvements.

Modern architectural shingles feature enhanced wind resistance, better granule adhesion, and improved algae resistance. Many offer warranties of 25 to 30 years. The variety of colors and styles complements virtually any GTA architectural design.

Repairs are simpler with asphalt shingles. Contractors can replace individual damaged shingles without extensive work, while metal roofing repairs require specialized skills.

Cost Comparison for GTA Homeowners

Budget considerations play a central role in roofing decisions. The cost difference between these materials extends beyond the initial installation price.

Initial Investment:

• Asphalt shingles: Lower upfront cost makes them attractive for immediate budget constraints
• Metal roofing: Higher initial investment but spreads cost over a longer lifespan

Long-Term Value:

• Metal roofs may never need replacement during your homeownership, eliminating future replacement costs
• Asphalt shingles require replacement every 15 to 30 years, creating recurring expenses
• Energy savings from metal roofing can offset initial costs over time

When evaluating costs, consider your plans for the property. If you plan to stay in your home for decades, metal roofing's longevity provides excellent value. For shorter-term ownership, asphalt shingles make financial sense. Additionally, metal roofing can significantly boost property value if you intend to sell, as prospective buyers often view it as a premium feature that eliminates the need for roof replacement in the near future, potentially commanding a higher resale price.

Performance in GTA Weather Conditions

The GTA experiences diverse weather that tests roofing materials: heavy snow, ice storms, heat waves, and severe thunderstorms.

Metal roofing handles Ontario winters exceptionally well. Snow slides off easily, reducing structural stress. The smooth surface prevents ice dams by allowing proper drainage. Metal resists cracking in extreme cold, unlike materials that become brittle.

Quality asphalt shingles perform reliably when properly installed. Architectural shingles include enhanced wind resistance for severe storms and improved temperature flexibility. However, shingles absorb more heat than metal, potentially increasing attic temperatures.

Both materials resist fire well, with metal offering the highest fire resistance rating.

Environmental Impact and Energy Efficiency

Metal roofing typically contains 25 to 100 percent recycled content and remains fully recyclable at end of life. Its reflective properties reduce cooling costs by 10 to 25 percent by reflecting solar radiation.

Asphalt shingles have improved environmentally, with many incorporating recycled materials and reflective granules. However, most end up in landfills after removal, though recycling programs are expanding.

Maintenance Requirements

Metal roofing requires minimal maintenance. Annual inspections for loose fasteners, damaged sealant, or scratches typically suffice. The material resists moss, algae, and mildew growth.

Asphalt shingles need more attention. Regular inspections identify damaged or missing shingles before leaks develop. Clean gutters regularly and address algae or moss growth in shaded areas.

Key Takeaways: Making Your Decision

The choice between metal roofing and asphalt shingles depends on your specific circumstances, budget, and priorities. Consider these key factors:

• Budget: Asphalt shingles offer lower upfront costs, while metal roofing provides better long-term value and home resale value
• Longevity: Metal roofing lasts significantly longer than asphalt shingles
• Aesthetics: Both materials offer variety, with shingles providing more traditional looks
• Energy efficiency: Metal roofing typically provides better cooling cost savings
• Maintenance: Metal roofing requires less ongoing maintenance than asphalt shingles
• Home value: Both materials protect your investment, though metal may offer higher resale appeal
