Abstract: The article deals with the system of flat roofs which slows down the runoff from large storm events by retention drains. During the critical time the system slows down the runoff, minimizes the impact on capacity characteristics of the sewer system and prevents it from being overloaded. The article describes factors influencing design of the system and its use in the context of sustainable rainwater management and green building.

Key words: retention roof, rainfall, drainage, sewer system, green roof.
