When it comes to selecting exterior siding in Ottawa, homeowners are often torn between vinyl siding and aluminum siding. Both options offer distinct benefits, yet choosing the right material depends on factors like climate, budget, energy efficiency, and long-term durability. This comprehensive comparison of vinyl vs aluminum siding will help you make the most informed choice for your home in Ottawa’s challenging weather conditions.
Understanding Ottawa’s Climate: Why Siding Material Matters
Ottawa experiences cold, snowy winters and hot, humid summers. These fluctuations demand siding materials that can withstand thermal expansion, moisture, and freeze-thaw cycles. Therefore, siding selection isn’t just an aesthetic choice — it’s a long-term investment in your home’s integrity.
Vinyl Siding: Affordable, Durable, and Low Maintenance
What is Vinyl Siding?
Vinyl siding is a plastic exterior cladding made from polyvinyl chloride (PVC). It has gained popularity across Ottawa due to its low cost, versatility, and weather resistance.
Benefits of Vinyl Siding in Ottawa
- Cost-Effective: One of the most affordable siding options.
- Insulation Options: Available in insulated panels that enhance energy efficiency — ideal for Ottawa winters.
- Low Maintenance: Requires only occasional cleaning.
- Variety of Styles: Mimics wood, shake, or stone aesthetics in numerous colors.
- Moisture Resistant: Doesn’t rot or corrode, making it perfect for humid summers and snowy winters.
Drawbacks of Vinyl Siding
- Less Impact-Resistant: Can crack under extreme cold or physical impact.
- Fading Over Time: Prolonged sun exposure may dull colors.
- Environmental Impact: Not biodegradable, although some options use recycled materials.
Aluminum Siding: Resilient and Fire-Resistant
What is Aluminum Siding?
Aluminum siding is made from rolled aluminum sheets, typically coated with enamel paint for color and protection. It’s been used for decades in both residential and commercial buildings.
Advantages of Aluminum Siding in Ottawa
- Highly Durable: Resistant to fire, rot, and pests.
- Eco-Friendly: Often made from recycled materials and fully recyclable.
- Performs Well in Cold: Doesn’t crack like vinyl in sub-zero temperatures.
- Paintable Surface: Can be repainted for a refreshed look over time.
Disadvantages of Aluminum Siding
- Dents Easily: Vulnerable to hail and physical impact.
- Fading & Chalking: Enamel coating may deteriorate and chalk over time.
- Noise Levels: Can be noisy during wind or rainstorms.
- Higher Maintenance: Requires periodic painting or treatment to maintain appearance.
Cost Comparison: Vinyl vs Aluminum in Ottawa
| Siding Type | Average Cost per Sq. Ft. (Installed) | Maintenance Cost | Lifespan |
|---|---|---|---|
| Vinyl Siding | $6 – $10 | Low | 20-30 years |
| Aluminum Siding | $8 – $12 | Moderate | 30-50 years |
While vinyl is cheaper to install, aluminum may offer longer lifespan depending on proper maintenance and Ottawa’s harsh winters.
Aesthetic Considerations and Curb Appeal
Vinyl Siding Aesthetics
- Rich color options
- Textures mimic wood grain
- Seamless installation with hidden fasteners
Aluminum Siding Aesthetics
- More industrial appearance
- Requires repainting for modern look
- Limited textural variety
If curb appeal is a top priority, vinyl siding may offer more design flexibility.
Energy Efficiency and Insulation Performance
In Ottawa’s cold winters, insulation matters. Vinyl siding often comes with foam backing that increases R-value and prevents thermal bridging. Aluminum siding, while strong, typically requires an additional layer of rigid foam insulation to compete with vinyl’s energy performance.
To increase energy savings, consider insulated vinyl siding endorsed by ENERGY STAR®.
Environmental Impact and Sustainability
- Vinyl Siding: Typically less eco-friendly unless using recycled content. Difficult to recycle at end-of-life.
- Aluminum Siding: 100% recyclable and often manufactured from recycled metals.
If sustainability is a priority, aluminum may be preferable. Learn more about sustainable siding materials.
Maintenance Requirements in Ottawa’s Conditions
Vinyl Maintenance Needs
- Occasional pressure washing
- No repainting required
Aluminum Maintenance Needs
- Repainting every 10–15 years
- Rust-resistant coatings may be necessary
- Dent repairs in high-impact areas
Fire Resistance: A Crucial Consideration
Aluminum siding is non-combustible, making it ideal in regions prone to wildfires or close urban housing. Vinyl, while fire-retardant, can melt or warp under intense heat.
Warranty and Manufacturer Guarantees
- Vinyl Siding: Often comes with limited lifetime warranties
- Aluminum Siding: Warranties vary; paint finishes typically covered for 25 years
Local Regulations and Installation in Ottawa
Working with a local contractor familiar with Ottawa building codes ensures compliance with municipal bylaws and climate-specific best practices.

FAQs
What is more energy efficient in Ottawa: vinyl or aluminum siding?
Vinyl siding, especially insulated vinyl, offers superior energy efficiency due to its built-in foam backing. Aluminum siding requires additional insulation to match this performance.
Does aluminum siding rust in Ottawa’s humid climate?
Although aluminum itself doesn’t rust, paint coatings can deteriorate over time, leading to oxidation or chalking. Regular maintenance helps preserve its appearance.
Can I mix vinyl and aluminum siding on my home?
Yes, some homeowners use vinyl for aesthetic sections and aluminum in high-impact areas. This hybrid approach can balance cost, durability, and curb appeal.
