When Ontario homeowners research metal roofing options, aluminum roofing sometimes comes up as an alternative to steel. But is it the right choice for homes in the GTA and surrounding areas? In this guide we break down everything you need to know about aluminum roofing in Ontario — including costs, pros and cons, and how it compares to steel.
What Is Aluminum Roofing?
Aluminum roofing is a type of metal roofing made from aluminum instead of steel. It’s available in several styles, including aluminum shingles, standing seam panels, and flat sheets. Aluminum is lightweight, naturally rust-resistant, and has been used in roofing for decades—particularly in coastal areas where salt air causes steel to corrode faster.
Aluminum Roofing Cost in Ontario
Aluminum roofing generally costs more than steel roofing due to the higher material cost of aluminum as a raw material.
Typical aluminum roofing costs in Ontario:
- Aluminum shingles: $10–$16 per square foot installed
- Aluminum standing seam: $9–$18 per square foot installed
For an average GTA home, this means total installed costs of approximately $18,000–$30,000—significantly higher than comparable steel roofing options.
Aluminum vs Steel Roofing: Key Differences
Corrosion Resistance Aluminum naturally resists rust and corrosion without any coating — this is its biggest advantage over steel. However, modern steel roofing products use G90 galvanized coatings and premium paint systems that provide excellent corrosion protection for 50+ years. For most Ontario homeowners the corrosion advantage of aluminum is not significant enough to justify the higher cost.
Weight Aluminum is lighter than steel—approximately one third the weight. This can be an advantage on older homes with weaker roof structures, reducing load on the building. For most modern homes, however, either material is suitable.
Durability Steel roofing is generally considered more durable than aluminum in Ontario’s climate. Steel handles the freeze-thaw cycles, heavy snow loads, and hail that are common across the GTA better than aluminum, which can dent more easily under impact.
Cost steel roofing is significantly more affordable than aluminum—typically 20–40% less expensive for comparable products. For most Ontario homeowners, steel roofing offers better value for money.
Availability Steel roofing products are much more widely available in Ontario than aluminum roofing. This means more color options, more styles, and more experienced contractors to choose from.
Is Aluminum Roofing Worth It in Ontario?
For most Ontario homeowners — no. Here’s why:
Ontario is not a coastal environment where salt air corrosion is a major concern. The main climate challenges in the GTA are snow, ice, freeze-thaw cycles, and wind—all of which steel roofing handles extremely well.
Steel roofing with a quality galvanized coating and premium paint systems will last 50+ years in Ontario’s climate without corrosion issues—matching aluminum’s main advantage at a significantly lower cost.
When aluminum roofing might make sense:
- You have an older home with a weaker roof structure that benefits from reduced weight
- You have a specific aesthetic preference for aluminum products
- Your contractor has specific expertise with aluminum installation
For the vast majority of Ontario homeowners, steel metal roofing is the better choice—more affordable, more durable against hail and impact, and widely available in dozens of colors and styles.
