Green roofs can collect rainwater by absorbing and slowly releasing it through evaporation and plant use. This natural process reduces runoff from impervious roof surfaces, benefiting the environment and water management systems. By providing a layer of plant material that acts as a sponge, green roofs help mitigate flooding, minimize pollution, and support sustainable urban infrastructure. The water-harvesting capabilities of green roofs contribute to a more eco-friendly and efficient approach to managing rainwater in urban areas.
