Green Roofs

From sedum roof to roof garden
Our offer

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:

    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.

    Green roof benefits

    Good for the environment

    Green roofs help reduce the urban heat island effect, improve air quality, and decrease greenhouse gas emissions.

    Rainwater retention

    It reduces water runoff and helps retain rainwater that can be used for irrigation.

    Better solar panel efficiency

    The efficiency of solar panels on a green roof will increase by 6 to 24%.

    Air-Purifying

    A green roof of 300m² captures 1 ton of particulate matter.

    Financial value rises

    A green roof enhances property values and mitigates the carbon footprint.

    Increased roof life

    A green roof provides protection against UV radiation and extreme temperatures.
