With greenroofs we can make the black roofs look more natural and better for the environment. Not only flat roofs are suitable for greenroofs, also for sloping roofs we can make it possible. Up to 45° sloping we use the normal system inserted with nets that prevents sliding off. When it's steeper we have to use special systems. There are a lot of choices for greenroofs, with sedum, schadowplants an even a real garden with a pond.
A greenroof based on sedum is the most common and possible on almost all the roofs. If you want to make it like a real living space you have to make sure your roof is strong enough.
