Green roofs, especially those containing succulents from the Sedum family, are not only aesthetically appealing parts of the urban environment, but are also amazingly resistant to cold and snow. In this article, we discuss how these roofs survive severe frosts and heavy snowfalls, highlighting their ability to maintain their beauty and functionality even in extreme cold conditions.


Winter challenge


In winter, most plants face difficulties, and plants used by green roofs are no exception. However, succulents used on the roof have a unique adaptability. These plants, known for their cold tolerance and ability to survive adverse conditions, are a real salvation for green roofs in winter.

Sedum's unique properties


Ability to retain moisture: Succulents or simply Sedum have a unique ability to collect moisture in their tissues, which helps them survive periods of drought and reduces the risk of freezing in severe frosts.

Resistance to low temperatures: Sedums have adapted to cold climatic conditions, which makes them an ideal choice for green roofs in areas with harsh winters, such as Finland.


Frost resistance


It is important to emphasize that green roofs with Sedum can successfully withstand severe frosts due to their natural resistance. During hibernation, these plants go into a dormant state, minimizing the need for energy and water. In this process, unlike grasses, the leaves of Sedums do not die and fire-safe dry residues are not formed.



Removing snow from the roof can damage both plants and the structure of the green roof. In the photo, sedum's green leaves pass through the ice and snow on the roof.

Winter treatment


The best thing you can do in winter is not to disturb the green roofs and the plants growing on them. Frost or snow are not a problem for a green roof. In winter, with the right care in spring and autumn, Sedum retains its properties.


Tips for Winter Care


Snow cleaning. If necessary, the layers of the green roof must be taken into account when clearing snow from the green roof in the winter season. Workers must be careful and be prepared to consider the layers of the green roof when removing snow. Actions must be taken carefully.


Finally, in winter, green roofs not only maintain their viability but also continue to perform their tasks, improving the environment, providing a home for many living organisms and increasing the energy efficiency of buildings. With the right care in the winter season, you can enjoy the beauty and benefits of a green roof at any time of the year.
