These roofs provide significant benefits, such as absorbing rainwater, which reduces the risk of flooding in urban areas. ( 1 ), they act as natural insulation, keeping buildings cooler in the summer and warmer in the winter, which lowers energy consumption.

Despite these advantages, the installation of green roofs can be costly. The structure of the building must be strong enough to support the extra weight of soil and plants. ( 2 ), regular maintenance is required to keep the plants healthy. However, many city planners believe the long-term environmental benefits outweigh the initial costs.
