How much does it cost to replace a roof in 2026? Replacing a roof is a significant investment, largely because of the price of materials and labour.
Depending on the budget you plan to dedicate to your roof, a number of options are available. There are also several types of flat roofs for different needs and preferences, and their cost can vary significantly. Let’s look at the different possibilities in terms of the types of flat roofs and the materials used, the advantages of each, and a rough budget idea.
Factors Influencing the Cost of Roof Renovation
What is the cost of a roof in 2026? It is difficult to provide a single average cost for roofing renovations, since the price varies widely by project. It depends on your existing roof, the scope of work, and the roofing contractor.
Size and Complexity of the Roof
The first factor to consider when calculating the cost of a roof in 2026 is the surface area and the scope of the job. Put simply, the larger the roof and the more complex the project, the more time and materials are required. The price of a flat roof in 2026 that also serves as a terrace will, for example, be higher than a simple flat roof with a single membrane.
The condition of your current roof can also have a major impact on the final bill. The prices shown here include the covering and installation only. They do not include related work such as repairing drains and gutters, reworking the attic space, or replacing insulation.
The level of complexity also matters. The presence of accessories and architectural elements adds to the challenge and increases costs. The same goes for a roof that is hard to access, which will require additional equipment and safety measures from the roofers.
Labour Cost
Another factor that can change the total cost is labour. Not all roofers charge the same rate. Prices vary depending on the season and demand. This is why costs are often slightly higher in urban areas.
Reputation and experience also influence rates. Specialists with many years of experience, such as the team at Clinique de la toiture FCA, will likely not charge the same hourly rate as a general handyman. In return, it can be worth paying a little extra for a roof that will last for years and help you avoid expensive interventions over time.
Finally, the chosen material has a strong impact on the cost of your flat roof in 2026. Fortunately, there are roofing grants available in 2026 that can help reduce the final bill.

How to Choose the Right Roofing Material
Each covering has specific properties and benefits. Likewise, different materials suit different types of flat roofs. Here is how they compare.
Advantages and Disadvantages of Materials
For flat roofs, the following options are generally distinguished:
- TPO and EPDM Membranes
These highly durable single-ply membranes must be installed by professionals. Poor installation can lead to water infiltration. That said, they offer many notable advantages, including an average lifespan of 25 to 35 years. In some cases, TPO and EPDM roofs can even last more than 50 years. - Elastomer Membrane
An elastomeric membrane is valued for its excellent resistance to UV rays, leaks, and tears. It is also a durable choice. It is not recyclable, and it is more expensive than some other membranes on the market. Installation by torch also carries a degree of risk. - Asphalt and Gravel
This covering is less common today and is often replaced by TPO membranes, in part because it requires more frequent maintenance. You need to redistribute the gravel regularly and inspect the roof. While it is affordable, its shorter lifespan, about 15 to 20 years, makes it less attractive than other options. It is also more vulnerable to UV damage and is not recyclable. - Green Roof
Whether you use it for cultivation or not, this type of roofing is very eco-friendly. It has been growing in popularity year after year, even in major urban centres. Beyond its aesthetic appeal, a green roof contributes to biodiversity and a building’s energy efficiency, and it helps with stormwater retention. However, it represents a significant investment and requires expertise. Your structure must be strong enough to support the weight. The experts at Clinique de la toiture FCA can assess whether your flat roof can support a vegetated roofing system and the work required. - Roof Deck
A roof deck or terrace lets you make the most of nice weather and maximize your outdoor living space, which is particularly appealing if your outdoor lot is small or non-existent. It can also enhance your home’s resale value in the long term when built to code by professional roofers.
Roof replacement prices, based on the materials used
Here is an idea of the price of a flat roof in 2026, depending on the materials selected.
Price of a TPO or EPDM membrane roof in 2026
These modern membranes offer many advantages at a competitive price for your flat roof. The costs of redoing your roof in 2026 with this type of membrane typically start between $11 and $16 per square foot, installation included. You will benefit from a watertight roof that withstands harsh weather and resists UV rays. Another advantage: they are recyclable.
Price of an elastomeric membrane
Gaining in popularity in recent years for flat or low-slope roofs, commercial buildings, and industrial facilities, the elastomeric membrane consists of a base layer topped with coloured granules to protect the surface from UV deterioration.
In 2026, the price for an elastomeric roof is generally between $11 and $21 per square foot, labour included. The range varies widely depending on the brand and the quality of the covering. (Prices may fluctuate based on the market.)
Price of an asphalt and gravel roof in 2026
Asphalt-and-gravel roofs are becoming less popular, in favour of greener, longer-lasting alternatives. If you choose this type of covering, expect to pay between $11 and $14.50 per square foot. (Prices may fluctuate based on the market.)
Price of a green roof in 2026
A leader for aesthetic and environmental benefits, a green roof will cost between $18 and $48 per square foot, depending on how much green space you want. More specifically, an extensive system is about $18 to $30 per square foot, while an intensive system is roughly $30 to $48 per square foot. (Prices may fluctuate based on the market.)
Price of a roof terrace
The price of a roof terrace varies greatly from one project to another. It depends on the scope, the materials used, additions and accessories, and several other elements. In spite of the expense, it provides additional living space and can positively influence your home’s resale value. Contact our roofing experts to discuss your project.
In any case, redoing your roof will bring welcome peace of mind, depending on the type of covering you choose.
Do not entrust this work to just any roofing company. Our best advice: do your research and ask for multiple quotes. Stay alert when you see so-called competitive pricing. If one contractor’s price is significantly lower than the others, you may end up facing extra charges or work quality that leaves something to be desired. That can lead to costly interventions in the future.
Request quotes, and research companies and contractors beforehand. Do not hesitate to contact the Clinique de la toiture FCA team to discuss your project and costs.
