Aluminum Roofing : a good choice ?

Choosing a roofing material is a important decision for any building in Quebec, especially given the harsh winters, temperature fluctuations, and frequent weather events. Among the most durable and high-performing materials on the market, aluminum roofing is gaining popularity. Lightweight, robust, and recyclable, this type of roofing offers excellent protection while requiring minimal maintenance.

In this guide, we as roofers present the various types of aluminum roofing, their advantages, and average prices.

What Is Aluminum Roofing?

Aluminum roofing is a type of metal covering designed to protect residential, commercial, or industrial buildings from weather conditions. Appreciated for its lightness, durability, and corrosion resistance, aluminum is an attractive alternative to traditional materials such as asphalt, steel, or concrete tiles.

Unlike other roofing materials, aluminum does not rust and maintains its appearance for several decades, making it an excellent choice for long-term investment.

Different Types of Aluminum Roofs

Aluminum Panels

Panels are often used for large surfaces and contemporary buildings. They feature long continuous strips that provide excellent waterproofing. This type of covering is frequently selected for its ability to quickly cover large areas and its modern, clean appearance.

Aluminum Tiles

Mimicking the appearance of traditional tiles, aluminum tiles offer a more classic aesthetic while providing the performance benefits of aluminum. They are particularly suitable for European or Mediterranean-style homes and are available in various textures and colors.

Aluminum Shingles

Visually closer to asphalt shingles, aluminum roofing shingles offer an excellent alternative for homeowners wanting to retain a traditional look while benefiting from aluminum’s properties. They are often used in renovations to replace existing shingles.

Advantages of an Aluminum Roof

Choosing an aluminum roof means opting for a high-performing, durable material perfectly suited to Quebec’s climatic conditions. Whether for new construction or renovation, aluminum provides numerous benefits, making it an increasingly popular choice among homeowners.

Excellent Weather Resistance

Quebec’s climate tests roofs with heavy snow, freezing rain, strong winds, and extreme temperature variations. Aluminum stands out for its ability to withstand all these elements. It does not crack or deform and retains its structure even after prolonged freeze-thaw cycles.

Its smooth surface also allows snow to slide off more easily, reducing accumulation and structural load.

Exceptional Lifespan

One of the biggest advantages of aluminum roofing is its longevity. An aluminum roof can last 50 years or more without significant performance loss.

Unlike asphalt shingles, which need replacing after 15 to 20 years, aluminum maintains its integrity over decades, making it a cost-effective long-term choice.

Lightweight Material Ideal for Existing Structures

Aluminum is an extremely lightweight metal. This property makes it an ideal solution for renovations on older homes or buildings with weaker frames.

Its light weight reduces the load on the structural support, making transportation and installation easier. It is also advantageous when covering an existing roof, as it can sometimes be installed without removing the old covering, depending on the roof’s condition.

An Ecological and Sustainable Choice

Aluminum is 100% recyclable without quality loss. Opting for aluminum roofing is therefore a concrete step towards environmental responsibility.

Besides being recyclable, aluminum often comes from recycled materials, reducing its ecological footprint right from production.

Minimal Maintenance

One of aluminum’s great practical benefits is that it requires very little maintenance. A simple annual visual inspection is often enough to ensure its condition. It does not rot, stain easily, or encourage the growth of moss or fungi.

A straightforward cleaning with clear water can restore its shine. For homeowners seeking a reliable, hassle-free material, this is an excellent solution.

Comparison: Aluminum or Steel Roofing?

Aluminum and steel are increasingly used in residential and commercial roofing projects. While similar, they serve different needs depending on building type, climatic conditions, and available budget. Here’s a clear overview to help you select the most suitable material for your project.

Aluminum vs. Steel: Which to Choose?

Criteria	Aluminum Roofing	Steel Roofing
Weight	Very light	Heavier
Corrosion Resistance	Excellent (does not rust)	Good, but requires treatment
Durability	40 to 60 years	30 to 50 years
Maintenance	Low	Moderate
Aesthetics	Wide choice of finishes and colors	More industrial look
Price	Higher	More economical
Environmental Impact	100% recyclable, energy-efficient	Recyclable but more energy-consuming

How Much Does Aluminum Roofing Cost?

The cost of aluminum roofing varies considerably based on factors such as the chosen product, surface area, installation complexity, and building characteristics.

Average Price per Square Foot

On average, aluminum roofing costs between $10 and $15 per square foot, including installation. Prices can vary depending on region, contractor choice, and desired finish.

Aluminum Shingles

Aluminum shingles are typically more affordable and easily installed on residential roofs. They offer a good balance between aesthetics and performance. Costs usually range between $9 and $13 per sq. ft.

Aluminum Panels

Standing seam or hidden fastener panels are more expensive due to their modern look and complex installation, ranging from $12 to $17 per sq. ft., depending on the model.

Tiles or Imitation Tiles

Models imitating tile or slate, which are more aesthetically intricate, fall into the higher price range, about $14 to $18 per sq. ft. These options are popular for high-end or heritage roofs.

Type of Aluminum Roofing	Price per sq. ft. (CAD)	Price per sq. m. (CAD)
General (average)	$10 to $15	$110 to $160
Aluminum Shingles	$9 to $13	$100 to $140
Aluminum Panels	$12 to $17	$130 to $185
Tiles/Imitation Tiles	$14 to $18	$150 to $195

Aluminum Roofing Installation

Installing an aluminum roof requires specific expertise to ensure performance, waterproofing, and longevity. Whether choosing panels, shingles, or tiles, certain steps must be followed for optimal results.

Installation Steps

The installation process generally involves several steps, whether for new installations or renovations:

• Inspecting the existing roof: The roofer assesses the structure, ventilation, and roof support.
• Preparing the surface: If needed, the old roofing is removed. A vapor barrier and waterproof membrane are often installed to reinforce waterproofing.
• Installing profiles or shingles: Aluminum elements are installed according to the chosen model (panels, shingles, tiles), ensuring proper overlap and secure fastening.
• Finishing and sealing: Moldings, flashings, and ventilation components are installed to enhance aesthetics and prevent water infiltration.

Each roof is unique; the installer will adapt techniques based on job complexity, slope, and architectural specifics.

Average Installation Duration

Project duration depends on roof size, aluminum type, and site accessibility. For a medium-sized building, installation can take between 3 to 7 days, including preparations and finishing. Booking in advance during peak season (spring-summer) is recommended to avoid delays.

Can Aluminum Roofing Be Installed Over Old Roofing?

Yes, in some cases, aluminum roofing can be installed over existing shingles, provided they are in good condition and the roof structure allows it. This approach reduces the costs associated with removing old materials and speeds up the project.

Why Hire a Certified Installer?

Installing aluminum roofing requires precise technical skills. An unqualified roofer could cause installation faults, leading to water infiltration, poor ventilation, or premature wear.

• Hiring an installer like Duro-Toit ensures:
• Installation adhering to building codes.
• Compliance with manufacturer’s installation standards.
• Warranty on materials and labor.
• Expertise suited to Quebec’s climatic conditions.
