In the case of a rooftop walking surface, compactable and pressure-resistant material is laid to guarantee that people can walk on it safely. Rainwater retention does play an important role on green roofs, but water needs to be drained quickly from pavement surfaces so that it doesn’t stay there for too long. Which is why good drainage is important.
