Why Install a Green Roof?

If you’re looking to make a positive impact on the environment while improving your home’s energy efficiency, stormwater management, air quality, and aesthetic appeal, installing a green roof is the way to go. Green roofs are living roofs that are covered in vegetation, and there are several benefits to be gained by going green.

One of the major benefits of green roofs is that they significantly reduce energy costs. During hot summer months, green roofs can lower indoor temperature by 6 to 8 degrees Celsius, reducing the need for air conditioning and related expenses. In winter, installing a green roof can also reduce heat loss by 25 to 30 percent, resulting in lower heating bills.

Green roofs also play a vital role in stormwater management. By absorbing and filtering rainwater, they reduce the amount of water that flows into storm drains and rivers, helping to prevent sewer overflows and reduce the risk of flood damage. Additionally, green roofs can help improve air quality by trapping pollutants and releasing oxygen.

From an aesthetic perspective, a green roof can enhance the appearance of your property, helping it to stand out in the neighborhood. Whether you want to showcase your commitment to the environment or simply enhance your home’s curb appeal, a green roof is a great choice.

“Installing a green roof is a simple and effective way to make a significant difference to the environment. By choosing to install a green roof, you are making a positive impact on our planet’s sustainability while also improving your home’s value and reducing energy costs.”

Understanding Canadian Climate and Green Roofs

When it comes to installing a green roof in Canada, there are several factors that homeowners must consider to ensure their roofing system can withstand the harsh Canadian climate and its temperature variations and precipitation levels. Choosing the appropriate plant selection for different regions is also important for a successful green roof installation.

In general, green roofs in Canada are subject to extended periods of cold temperatures in winter, high humidity levels, and occasional frost and snow. These conditions vary significantly across the country, such as in the coastal climate of British Columbia, which experiences high levels of rainfall, versus the dry, arctic climate of Northern Canada.

Despite these challenges, many Canadian homeowners have successfully installed green roofs on their homes, enjoying the benefits of improved insulation, energy efficiency, and enhanced aesthetics. Additionally, green roofs can help mitigate the urban heat island effect in densely populated areas, which can have a significant impact on overall air quality in cities and residential areas.

Plant Selection for Green Roofs in Canada

When selecting plants for a green roof in Canada, homeowners must consider the specific climate conditions of their region, including temperature and moisture levels. Native plants that are well-suited to cold and damp conditions, such as sedum and other succulent plants, are ideal choices for green roof installations.

Additionally, certain plant species that can help purify the air, such as mosses and ferns, are popular options for green roofs in Canadian homes. These plants can also contribute to biodiversity, attracting insects and other small wildlife.

“Choosing the appropriate plant selection for different regions is also important for a successful green roof installation.”

Overall, understanding the specific challenges and opportunities related to green roofs in Canadian climates is essential for achieving a successful, sustainable, and long-lasting installation. With careful planning, appropriate plant selection, and the expertise of a reliable and experienced roofing company, green roofs can transform the energy efficiency and environmental sustainability of Canadian homes.

Assessing Your Roof’s Suitability

Before installing a green roof, it’s important to assess the structural integrity and load-bearing capacity of your existing roof. Green roofs are weighty, and the additional load on your roof must be supported by the building without causing damage or structural issues. Here’s how to check if your roof is suitable for a green roof installation:

Step 1: Roof Assessment

  • Check the age and condition of your roof.
  • Make sure there are no leaks or damage to the roof.
  • Check for any weak spots or sagging, which could indicate structural issues.

Step 2: Load-Bearing Capacity

The load-bearing capacity of your roof is another critical factor to consider. A green roof can weigh anywhere from 15 to 50 pounds per square foot, depending on the depth of soil and the plant selection. Most roofs are designed to support extra weight, but it’s essential to check the weight capacity of your roof and ensure it can handle a green roof installation.

Step 3: Other Factors

It’s also important to consider other factors like the size and slope of your roof, sun exposure, and waterproofing. These factors can impact the installation process and the long-term sustainability of your green roof.

“Installing a green roof without proper roof assessment can lead to costly damages. It’s essential to ensure your roof is structurally sound and has the necessary load-bearing capacity before undertaking a green roof installation.”

Planning and Designing Your Green Roof

Planning and designing your green roof is a crucial step in the installation process that directly impacts the success of your sustainable project. To begin, assess your roof’s load-bearing capacity, slope, and drainage systems to determine its suitability and potential for a green transformation. Once you have established your roof’s capabilities, select appropriate plants and growing media that are adapted to the local climate and environment.

Consider incorporating a variety of plants to create a biodiverse ecosystem that can thrive in harsh Canadian weather conditions, such as evergreens, sedums, and grasses. These plants have an extensive root structure that can retain water and provide strong erosion control. Additionally, make sure to choose plants that can withstand high wind speeds, extreme temperatures, and seasonal changes.

When designing your green roof, think about the visual aspect and how it can complement your home’s style and aesthetic. Integrate different textures, colors, and heights for a harmonious and attractive layout. Consider using a mixture of native and non-native plants to create a unique, diverse green roof that showcases a range of styles and elements.

Finally, ensure that your green roof design incorporates a strong and efficient drainage system to prevent waterlogging and potential leaks in your roof’s structure. The drainage medium and layers should be planned and installed accurately to allow water to drain efficiently from the roof’s surface while retaining sufficient moisture for the plants to thrive.

Green Roof Installation Process

Installing a green roof may seem daunting, but with our step-by-step guide, the process can be straightforward and stress-free.


The first step in installing a green roof is ensuring that the roof surface is clean, clear of debris, and structurally sound. After ensuring that the roof is safe, lay down protective sheeting on top of the existing roofing materials to protect against punctures and minimize the risk of water leakage during construction.


Proper waterproofing is essential for the success of a green roof. Install a waterproof membrane on top of the protective sheeting, making sure to seal edges and corners securely. This membrane will prevent water from penetrating the roof and causing damage to the building’s structure.

Insulation Layers

Adding insulation layers is the next crucial step in the installation process. Start with a drainage layer to direct excess water toward the roof’s edges, followed by a filter layer to prevent soil from clogging the drainage system. Next, add a growing medium layer that will allow the plants to root and thrive. Finally, top it off with a vegetation layer customized to suit the roof’s specific shading, moisture, and exposure conditions.

Green Roof System Installation

With the insulation layers in place, it’s time to install the green roof system. This may include modular green roof trays or custom-built systems, depending on the specific needs and requirements of the project. Follow manufacturer instructions carefully to ensure proper installation and placement.

Finishing Touches

To complete the installation process, check for any gaps or areas needing additional soil or vegetation. Water the green roof regularly to support plant growth and establish a healthy, thriving ecosystem.

Now that the green roof has been successfully installed, it’s time to sit back, relax, and enjoy the many benefits of this environmentally-friendly upgrade to your home.

Maintenance and Care for Your Green Roof

Once your green roof is installed, it is important to maintain and care for it to ensure its longevity and health. Regular maintenance practices will not only protect your investment but also ensure that your home is benefiting from all the environmental advantages that come with a green roof. Below are some essential green roof maintenance and care tips:

  • Watering schedule: Depending on the climate, your green roof may require watering every 7-10 days, especially in the summer months. Regularly check the soil moisture levels and adjust the watering schedule accordingly.
  • Weed control: Keep an eye out for weeds and remove them as soon as possible to prevent them from overtaking your green roof. Be careful not to pull out the plants you want to keep.
  • Pruning and trimming: Regularly trimming the plants on your green roof will help keep them healthy and attractive while preventing excessive growth that could cause damage.
  • Regular inspections: Regularly inspect your green roof for any damage, including leaks, cracks in the waterproof membrane, or other issues. Address any problems immediately to prevent larger issues from arising.

By following these simple maintenance and care tips, you can ensure that your green roof will continue to provide environmental benefits to your home for years to come.

Obtaining Permits and Insurance

Installing a green roof requires obtaining permits and insurance, which are necessary before starting the project. Green roof permits are mandated by most municipalities and vary by region, so it’s important to check with your local authorities to understand the required permits for your region. The installation process may also need to comply with specific regulations, such as building codes and zoning policies.

When selecting a roofing company, ensure that they carry appropriate insurance coverage, specifically liability insurance, and workers’ compensation insurance. This will protect you in case of any damage to your property or any accidents that may occur during the installation process. Verifying insurance coverage will protect you from potential lawsuits and further expenses.

Green Roof Permits

Before installing a green roof, you need to obtain the necessary permits from your local authorities. These permits will specify the requirements for designing, installing, and maintaining a green roof. They may vary in terms of cost, application procedures, and validity duration across different regions. Failure to obtain the proper permits can lead to fines and legal issues. Hence, it’s essential to be aware of your local green roofing regulations and mandated permits before starting the installation process.

Insurance for Green Roofs

When selecting a roofing company to install your green roof, you must ensure that they carry appropriate insurance coverage, specifically liability insurance and workers’ compensation insurance. Here are some points to consider:

  • Liability insurance: This type of insurance covers any damage and liability claims resulting from property damage, accidents caused by the company during installation, or any negligence on behalf of the company.
  • Workers’ compensation insurance: This insurance covers the medical treatment and lost wages for workers who are injured while working on your property.

It’s important to verify the company’s insurance coverage by asking for a copy of their insurance policy. Confirming the insurance coverage of the company will give you peace of mind and a level of protection if anything unforeseen happens during the green roof installation process.

Cost Considerations and Return on Investment

When considering installing a green roof, it’s important to keep in mind the associated costs. While green roofs can be initially more expensive than traditional roofs, the long-term benefits can outweigh the upfront expenses.

The cost of installing a green roof can vary based on factors such as the size of the roof, the type of vegetation, and the installation method. On average, green roof costs in Canada range from $10 to $40 per square foot. However, the initial investment can result in significant savings in the long run.

One of the key benefits of a green roof is energy efficiency. By covering the roof with vegetation, a green roof can help regulate indoor temperature, reducing the need for heating and cooling. This can result in up to 30% energy savings, according to some estimates.

Green roofs can also prolong the lifespan of the roof by protecting it from environmental factors such as UV rays, extreme temperatures, and precipitation. A traditional roof may last up to 20 years, while a green roof can last up to 40 years with proper maintenance.

The long-term return on investment (ROI) of a green roof is also worth considering. Studies have shown that a green roof can increase property value by up to 15%. Additionally, a green roof can reduce stormwater runoff, which can result in savings on infrastructure costs for cities and municipalities.

Overall, the upfront costs of a green roof may seem daunting, but the potential cost savings and ROI make it a worthwhile investment for homeowners seeking sustainable living solutions.
