What is the cost of re-roofing in 2025?

Thinking about changing your roof this year and wondering about the budget?

At Les Couvreurs Duro-Toit, we understand that the roof cost is one of the most important factors in any renovation project. Whether you’re considering asphalt shingles, metal roofing, or a membrane system, understanding the roof change price helps you make the best decision for your home.

In this article, we break down the cost to redo a roof in 2025, based on materials, surface area, and other key factors.

Factors that influence the price of changing a roof

Before diving into numbers, let’s look at what impacts the cost of changing a roof:

• Roof surface area: The bigger the roof, the higher the roof cost, especially if priced per square foot.
• Roof pitch: Steeper or more complex roofs usually cost more to replace.
• Material type: The price difference between asphalt shingles, metal roofing, or TPO/EPDM membranes can be significant.
• Accessibility: Hard-to-reach roofs require more time and equipment.
• Weather conditions: Winter jobs often come with extra fees.
• Labor: The experience and quality of your roofing contractor affect the final roof change price—but it’s also a guarantee of durability.

Roof price per square foot: our estimates

The most common way to estimate a roof cost is by square foot. Here are the average prices in Quebec for 2025:

Cost of a roof with asphalt shingles

Asphalt shingles are the most common roofing material in Quebec for single-family homes. They’re affordable, easy to install, and available in a variety of colors.

• Roof price per square foot: $6 to $12
• Lifespan: 15 to 25 years (up to 50 years for new-gen models)
• Cost to redo roof for a 1,000 sq. ft. bungalow: $7,000 to $12,000

Asphalt shingles offer a great price-to-quality ratio and a wide range of styles, but they’re less durable than other options and vulnerable to UV and humidity without proper roof ventilation.

Metal roofing cost

Metal roofs are gaining popularity due to their extreme durability and low maintenance. A smart choice for upscale homes, cottages, or commercial buildings.

• Steel or aluminum roofing: $13 to $28 / sq. ft.
• Copper roofing: Up to $30 / sq. ft.
• Lifespan: 50+ years
• Roof change price for 2,000 sq. ft.: $26,000 to $56,000

Metal roofing stands out for its weather resistance, fireproof qualities, snow load capacity, and eco-friendliness. However, it involves a higher initial roof cost and can be noisier during heavy rain.

Cost of TPO or EPDM membrane roofing

These membranes are ideal for flat roofs on duplexes, triplexes, and commercial buildings.

• Roof price per square foot: $11 to $16
• Lifespan: 25 to 35 years (or more)
• Cost to redo roof for 1,000 sq. ft.: $11,000 to $16,000

TPO and EPDM membranes resist UV, require low maintenance, and are recyclable. That said, they need professional installation, and seams can age over time.

Elastomeric membrane roof cost

Widely used for flat roofs, elastomeric membranes are two-layer systems that resist UV, cracking, and water infiltration.

• Roof price per square foot: $11 to $21
• Lifespan: 25 to 35 years
• Roof change price for 1,000 sq. ft.: $11,000 to $21,000

This membrane is durable and weather-resistant, and can be installed year-round. These advantages explain why the cost of changing a roof with this system is slightly higher.

Green roof cost

Green roofs are increasingly popular in cities like Montreal for their environmental benefits.

• Extensive green roof: $18 to $30 / sq. ft.
• Intensive green roof (with garden/terrace): $30 to $48 / sq. ft.
• Lifespan: around 30 years

Green roofs provide excellent thermal insulation, manage rainwater well, and add visual appeal. But they require structural reinforcement, seasonal maintenance, and a higher upfront investment.
