Everything about our green roofs
Curious about our green roofs? Here you’ll find the most frequently asked questions. Want to know more? Contact us directly with one click.
What is a green roof?
A green roof is a flat or pitched roof covered with vegetation, such as Sedum, herbs, or ornamental grasses. A green roof is also known as a vegetated roof, roof garden, or living roof. There are different types, each with its own structure, appearance, functionality, and benefits. Common variants are extensive (lightweight) green roofs and intensive (roof garden) green roofs.
What is an extensive and an intensive green roof?
An extensive green roof consists of a thin substrate layer (max. 15 cm) with a drainage layer underneath. This makes the system lightweight and relatively affordable.
Extensive green roofs are often planted with Sedum species, sometimes supplemented with herbs and flowers, such as in the Biodiverse green roof. Due to the thin build-up, these are classified as extensive or semi-extensive.
An intensive green roof, also known as a roof garden, has a thicker substrate layer (25 cm or more). This allows for planting shrubs and even trees, but it also makes the system heavier and more expensive.
What are the benefits of a green roof?
A green roof offers many benefits: it retains water, purifies the air, reduces temperature, saves energy, increases biodiversity, and extends the lifespan of the roof. In addition, it improves people’s well-being and enhances the value of buildings.
Can a green roof cause leaks?
No, a leakage is never caused by the green roof itself, but by roof coverings that are not waterproof or not root-resistant. Always check the quality of the roof covering beforehand. If you are unsure about its root resistance, it is recommended to install a root-resistant membrane as extra protection.
Can a green roof withstand frost?
Yes, a green roof with Sedums is always hardy. In the winter, Sedums are at rest and they will turn red. Vegetation roofs with grasses, herbs and host plants will be dormant in the winter months, but will come into full bloom again in the spring. All plants used in our vegetation blankets for green roofs are perennial plants.
