Edging for green roofs

Green roofs, also known as living roofs or vegetated roofs, is gaining popularity as a way to reduce the environmental impact of buildings. These roofs are covered with vegetation, reducing heat build-up, improving air quality, and providing habitat for wildlife. However, in order for a green roof to function properly, it’s important to consider the role of green roof edging.

A barrier between roof structure & vegetation

Roof edging is the perimeter edge of the roof. It is designed to prevent soil erosion and retain moisture. The edging also serves as a barrier between the green roof and the building structure. It will protect the roof and prevent water from seeping into the building. There are several different types including metal, concrete, and plastic.

Material options

Metal edging is a popular choice for green roofs because it is durable, weather-resistant, and can be easily customized to fit the shape and size of the roof. Metal edging also has a clean, modern look that complements the natural beauty of a green roof. Concrete edging is another option that is highly durable and resistant to weathering. However, concrete can be more difficult to install, is heavier and cannot be customised as easily as metal.

Plastic edging is a more affordable option that is easy to install and lightweight. But, plastic is not as durable as metal or concrete and may not hold up as well over time. It’s important to choose a high-quality plastic edging that is specifically designed for use with green roofs.

When choosing roof edging, it’s important to consider the aesthetic and functional requirements of the project. The edging should be able to withstand the weight of the soil and vegetation, and should be installed at a height that allows for proper drainage. The edging should also be able to withstand extreme weather conditions, including wind, rain, and snow.

Edging maintenance

In addition to selecting the right type of edging, it’s important to maintain the edging over time. Regular maintenance can help to ensure that the edging is functioning properly and that the green roof is performing at its best. This may include inspecting the edging for signs of wear and tear, cleaning debris from the edging, and replacing any damaged or worn sections.

Green roofs and green roof edging are important components of sustainable building design. By selecting the right type of edging and maintaining it over time, building owners can ensure that their green roofs are functioning properly and providing maximum environmental benefits.
