GREEN - Roofing System
Every type of green roof needs maintenance.
Extensive green roofs require very little maintenance. In the first year of life it is advisable to inspect the extensive vegetation preferably every three months. After that, one inspection per year is sufficient.
Maintenance is usually limited to:
fertilize with nutrients
remove any weeds
sow where necessary
remove general pollution, including accumulated leaves;
check all roof details.
Intensive green roofs generally require the same maintenance level as a normal garden. The choice of plants will determine the extent and frequency of the necessary care.
