Replacing your conservatory roof in Canada is crucial for both aesthetics and efficiency, given the country’s diverse weather conditions. This guide covers essential material options, costs, and specific considerations for Canadian homeowners.

Understanding the Need for Replacement

The lifespan of a conservatory roof in Canada depends largely on the materials used and the local climate. Generally, a conservatory roof may need replacement after 20 to 25 years. Signs that you might need a new roof include leaks, visible wear, and poor thermal performance, which can lead to higher heating bills during the harsh Canadian winters.

Roof Material Options

  1. Polycarbonate: A popular choice due to its affordability and reasonable durability. It typically costs between CAD $4,000 and $7,000 to replace a conservatory roof with polycarbonate sheets. While cost-effective, it offers less insulation than other materials.
  2. Glass: Offers better aesthetics and improved thermal efficiency compared to polycarbonate. The cost for a glass conservatory roof replacement typically ranges from CAD $6,000 to $10,000, depending on the type of glass and treatments for energy efficiency.
  3. Solid Roof (Tiles or Metal): Provides excellent insulation and durability. This option can be more expensive, ranging from CAD $10,000 to $20,000, but it is ideal for conservatories that are used year-round. Solid roofs also help in maintaining a consistent indoor temperature.

Step-by-Step Replacement Process

  1. Assessment: Hire a professional to assess the current condition of your conservatory roof. This evaluation will determine whether a full replacement is necessary or if repairs might suffice.
  2. Choosing Materials: Select the roofing material that best suits your needs in terms of durability, thermal insulation, and aesthetic preference. Consider the local climate and how much you’re willing to invest upfront versus potential energy savings.
  3. Finding a Contractor: Choose a reputable contractor experienced in conservatory roof replacements. Obtain several quotes to ensure competitive pricing, and check references to gauge the quality of their past work.
  4. Installation: The installation process typically takes 1 to 3 days, depending on the complexity and size of the roof. Ensure that the installation is scheduled during a period of mild weather to avoid delays.
  5. Post-Installation: After installation, have the roof inspected by a professional to ensure everything has been installed correctly and is up to local building codes.

Considerations for Canadian Homeowners

  • Energy Efficiency: With Canada’s cold climate, choosing an insulated roof material can significantly reduce heating costs.
  • Building Codes: Ensure the replacement meets all local building codes, which may vary by province or territory.
  • Weather Resistance: Consider materials that can withstand heavy snowfall, ice, and potential damage from high winds or hail.

Cost vs. Value

While the initial cost of replacing a conservatory roof can be high, the investment often pays off in terms of increased property value and reduced energy bills. A well-insulated roof can save up to 25% on energy bills, making it a cost-effective long-term choice.


Replacing a conservatory roof in Canada involves careful planning and consideration of both materials and costs. By understanding the options and processes, homeowners can make informed decisions that enhance both the value and comfort of their homes.
