Green Roofs
Green roofs enhance both the sustainability and aesthetics of your building. Expertise is crucial for the successful installation and maintenance of a green roof, so it is important to choose a contractor with solid references.
Extensive green roofs
An extensive green roof consists of a thin layer of vegetation and a large amount of substrate. It is relatively lightweight, easy to install, and requires minimal maintenance. There are several types of extensive green roofs:
Green roof with vegetation mats- Green roof with cassettes
- Green roof with sown sedum cuttings
- Green roof with sown sedum cuttings
Intensive green roofs
An intensive green roof is a roof vegetation system that consists of a thicker layer of substrate and a wide variety of plants. It requires more maintenance and irrigation than an extensive green roof.
Intensive green roofs can vary from a roof garden to a fully accessible green space with shrubs and trees. Due to the variety of plants and the thicker substrate layer, the weight can be high. This should be considered in the design of the building.

Frequently asked questions
What is an extensive green roof?
Extensive green roofs have a thin vegetation layer and a relatively thin substrate layer; they are light, easy to install and require little maintenance. They can be placed by means of roll-off vegetation mats, vegetation cassettes or by sowing sedum cuttings on the substrate layer.
What is an intensive green roof?
Intensive green roofs have a deeper substrate layer and a wider variety of plants; they resemble roof gardens and require more maintenance and irrigation. The extra weight must be factored into the building design.
What are the benefits of green roofs?
Green roofs reduce the urban heat island effect, improve air quality and reduce greenhouse gas emissions. They buffer rainwater, increase the efficiency of solar panels by 6-24%, filter particulates (300 m² captures 1 ton of particulates), increase property value and extend the life of the roof.
Why do I need a specialized contractor for a green roof?
The installation and maintenance of green roofs require expertise. Once the green roof has been installed, repairing any leaks is a greater challenge. Choosing a partner with expertise in waterproofing and green roofs seems the best choice.
