The design that is chosen for roof areas must take account of other

Drinking water
Water must be incorporated into the green balance sheet, to focus on
the building’s water consumption and allow the individual households to
compare their consumption against the average.
Drainage
In cases where it is not possible to use the SUDS strategy and plant
green roofs, the reasons for this must be documented and an in-depth
study made of the consequences that this will have for the volume of
the discharges and storm-water releases into the recipients. It might be
necessary to delay the water on the property.
