Green roof roof drains.
Green roof solutions offers many different drainage layer options depending on system goals regarding water retention.
The design of the different drainage layers allows for a portion of the stormwater to be retained above where the water is allowed to flow freely off of the roof.
During a dry period the water stored can be reabsorbed by the vegetation layer above.

Intensive layered green roof intensive green roofs have a deeper soil depth therefore the roof drain enclosure height is typically 12 or more.
It buffers water and allows excess water to drain away.
Z110 green roof drains are available with enclosure heights ranging from 5 to 18 or as specified.
The most critical role of the drainage layer is to provide an adequate flow of water off the roof during and after rainfall.
The drainage layer has an important role to play in the total system structure of a green roof.
