Upgrading to a metal roofing system is one of the most durable and visually impactful improvements a homeowner can make. But before you commit to a new metal roof, it’s important to understand the details that affect performance, longevity, and your investment — especially here in Ontario where weather conditions can be demanding.
At Classic Products Roofing Systems Inc., we’ve helped hundreds of Ontario homeowners choose and install metal roofing systems that perform beautifully for decades. Below are the top 10 things every homeowner should consider before upgrading to metal.
1. Climate & Weather Performance in Ontario
Ontario’s climate includes:
- Heavy snow loads
- Freeze-thaw cycles
- Ice dams
- High summer heat
- Wind and rain
A properly designed metal roofing system must be engineered to handle all of these conditions. Metal roofing excels when installed with proper ventilation and flashing, and it helps protect your home year-round.
2. Roof Structure and Condition
Your roof’s underlying structure must be in good shape before metal roofing is installed. During our inspection, we evaluate:
- Deck integrity
- Sagging areas
- Rot or water damage
- Insulation and ventilation
If the structure needs repair, it’s best to address this before installing premium roofing.
3. Metal Roofing System Type
Not all metal roofs are the same. Two major distinctions are:
- Direct-to-deck 4-way interlocking systems — industry-leading weather resistance
- Batten-mounted systems with exposed fasteners — less performance, higher maintenance
In Ontario’s varied environment, interlocking systems with hidden fasteners are generally the better choice for long-term durability and weathertight performance.
4. Material Choice: Steel vs Aluminum
Metal roofing materials differ:
Aluminum
- Excellent corrosion resistance
- Lighter weight
- Ideal for coastal and high-moisture areas
Steel
- Higher tensile strength
- Very durable
- Exceptional performance in snow and ice
Your choice depends on your home’s design and environmental exposure — but both steel and aluminum metal roofing outperform traditional materials when installed properly.
5. Energy Efficiency & Insulation
Metal roofs reflect more solar radiation than asphalt shingles, which can help reduce cooling costs in summer. When combined with proper attic ventilation and insulation, a metal roof can improve your home’s energy performance — something Ontario homeowners appreciate during both summer heat and winter cold.
6. Warranty and Product Support
A strong warranty reflects confidence in the roofing material. Many high-quality metal roofs offer:
- Long manufacturer warranties (often 40–50 years)
- Non-prorated coverage
- Transferable options in some cases
At Classic Products Roofing Systems Inc., we ensure warranty terms are explained clearly so you know what is covered and how to register your product.
7. Installation Matters More Than You Think
Metal roofing performance depends heavily on expert installation. In Ontario:
- Ice dam protection
- Flashing at chimneys, valleys, and vents
- Proper underlayment
- Secure fastening and panel alignment
These details separate a metal roof that lasts decades from one that causes issues. Our experienced installers ensure every detail is handled professionally.
8. Maintenance Requirements
One of the main benefits of metal roofing is that it requires minimal maintenance compared to asphalt shingles. However, regular inspection is still recommended to catch issues early — especially after severe weather. Hidden fasteners and interlocking panels reduce the need for ongoing adjustments.
9. Aesthetic & Style Options
Metal roofing no longer means plain panels. Today’s metal roofs can replicate styles such as:
- Cedar shake profiles
- Slate-style panels
- Architectural metal shingles
These options give Ontario homes striking curb appeal while maintaining premium performance.
10. Long-Term Value and Resale Impact
While metal roofing typically costs more upfront than shingles, it often delivers lower lifetime cost due to durability and minimal repairs. In Ontario’s real estate market, a high-quality metal roof can also increase resale value and attract buyers who appreciate durability and low maintenance.
Final Thoughts for Ontario Homeowners
Upgrading to metal roofing is a smart decision when it’s done with knowledge and experience behind it. Whether you’re replacing an aging roof or building a new home, the right metal roofing decisions — from material choice to installation — will impact performance for decades.
