When renovation work is no longer sufficient to maintain your roof in perfect condition, it is time to consider a complete replacement. This step is crucial to ensure the safety and efficiency of your roof. A quality structure and durable materials are essential to guarantee optimal protection, especially against Montreal's climatic conditions. The choice of materials and the budget are important elements to consider in your roof replacement project.

There are several types of roofs, each with its own characteristics. Here are the most common ones:

• Shingle Roof: Recent models are durable and resistant, offering a wide range of colors and styles. Asphalt shingles are highly resistant to moisture and easy to maintain.
• Slate Roof: Elegant and resistant, slate offers exceptional longevity (up to 150 years) but requires regular maintenance and particular care during installation.
• Metal Roof: Practical and recyclable, it is highly resistant to bad weather, but requires treatments to prevent corrosion. It can be noisy during bad weather.
• Flat Roof: This type of roof is primarily used in urban environments. It must guarantee perfect waterproofing to prevent leaks.
• Green Roof: Ideal for an ecological approach, it is resistant to bad weather and is aesthetically pleasing. It requires regular maintenance.

The choice of materials for a roof replacement depends on the type of roof chosen and the desired characteristics. Here are the most commonly used materials:

• Asphalt: Very popular for asphalt shingles, this material is easy to install and highly resistant to moisture.
• Wood: Used for wood shingles, it offers good waterproofing but requires regular maintenance to prevent fire risks.
• Metal, Aluminum, or Copper: These materials are durable, weather-resistant, and ecological. They offer great longevity with little maintenance.
• Elastomers: Used for flat roofs or other structures, these materials are highly resistant to bad weather and can be installed in any season.
• Vegetation: Ecological materials that provide natural insulation and improve the roof's aesthetics.

The cost to replace your roof will depend on the type of materials chosen and the surface area to be covered. Here is a price estimate:
