Why does rooftop greening fail? | Structural causes of rooftop greening
Is that rooftop greening really being considered under the premise of "being established"? The failure of rooftop greening is determined before the planning of the rooftop greening and before the construction of the rooftop greening.
This site is not intended to introduce or recommend products, methods, or systems for rooftop greening. In the field of rooftop greening, failures such as "the condition deteriorated after a few years," "it hasn't died but hasn't achieved the expected greenery," and "it was neglected due to lack of ongoing management" continue to occur. Many of these issues arise not from specific rooftop greening systems, methods, construction techniques, or management practices themselves, but from discrepancies in the assumptions and judgments made in the early stages of consideration. This site organizes ten items to check before making a decision, such as whether deterioration will not occur if watering stops during high temperatures and dry conditions, whether the flow of water and soil during heavy rain can be explained, whether management remains realistic even with increased weeds, and whether a temporary halt in management will not be fatal. It also questions whether decisions are being made solely based on performance records, advertising claims, catalog figures, and long-term guarantees. If there is even one item that cannot be fully explained, it is recommended to pause and verify it in detail. These are simple checks to reconsider the assumptions before "choosing" rooftop greening. More specific explanations and supplementary information can be compiled into a one-page A4 PDF, which can also be used as shared material during discussions. It will also help clarify the understanding between designers and clients.
