The intensive green roof is similar to a roof garden and can be planted and used in a similar way to a “normal” garden – even small trees can be grown here. This type of green roof is hardly possible to build yourself, especially since the statics of the roof must first be examined to ensure that the roof can withstand such a weight, namely several hundred kilos per square meter (!).
