Ministry of Transportation do not permit blue roofs to form part of a SWM plan owing to concerns over long term maintenance; this affects relatively few projects. The concerns arise from instances where building operators have found outlet control structures blocked with leaves or other debris. Without understanding the purpose of the device, these have been removed to prevent recurrence of the blockage. A study in New York City found that a modular system of trays outperformed an outlet flow control device in stormwater management[1]. It might reasonably be expected that a modular system would present fewer opportunities for complete failure from a single action, either through clogging or breakage of an storage element.

These products are designed to suspend green roof (or other) systems above a layer of free water for the detention period.
