What are green roofs? What are Native Roofs?
Native Roofs mimic the original state of the land your building is built on. They include diverse native plant species and design elements which attract and support native insects and birds.
Native Roofs and green roofs are essentially a built-up areas on a roof surface covered in a growing medium and vegetation. Designs for green roofs can be simple as a layer of sedum and can be as complex as your imagination would like.
Native Roofs tend to have less complex design features and mimic the natural environment by using native plant species and including design elements that attract and support native insects and birds. This has the benefit of:
requiring less maintenance and irrigation. When properly established, they can require no irrigation outside of drought events.
maintaining their original design. Highly manicured green roofs are expensive to establish and maintain and can lose their original design as more dominant species take over and as native species are introduced through the wind.
providing habitat for native plants, insects and birds and supporting the native prairie ecosystem.
raising public awareness and understanding of our natural ecosystem.
Appropriate plant selection is key to establishing a Native Roof. Finding the balance between plants that will survive in a rooftop environment, those that provide suitable habitat for native animals and insects, and those that are native to the region is key to establishing authentic and healthy Native Roofs.
Some examples of species appropriate to Southern Alberta are: june grass, rocky mountain fescue, blue grama, prairie aster, creeping goldenrod, sagebrush, yellow penstemon, and prickly pear cactus.
Our Native Roofs are designed to attract and support a variety of native insects and birds. To do this, we select diverse and appropriate vegetation and include varied topography and other structures that create a more appealing habitat.
Depending on the specifications and location of your building, your maintenance requirements and preferences, your roof might also be suitable for:
Bird or bat boxes
Artificial beehives or solitary bee habitats
