By the vegetation layer that holds and filters a significant percentage of the stormwater, water leakage to sewer systems is greatly diminished. Water obtained from the rainwater collection can be used in low flushed toilets, agriculture zones, and greenhouses.
The quality of the growing medium and the mixture of the soil materials affect the life cycle of the vegetation. In that medium, the soil is engineered with a mix of inorganic matters such as sand, gravel, or lightweight aggregate, with organic matters as compost, warm casting.
Vegetation selection is an important criterion where both aesthetics. Maintenance and climate should be considered. It is crucial to create vegetation-free zones around the roof, approximately 30 cm (12 inches).
In green roof systems, having the irrigation systems as part of the establishment stage is crucial for arid and semi-arid climate zones. There will be some unique systems where no irrigation system is needed, but it is related to the vegetation type. However, selection of the system is also essential; drip, capillary or spray irrigation can be used depending on again the vegetation type and growing medium.
