Green roof drainage is meant to drain the layer of soil on the roof

Green roofs enjoy great popularity for making cities greener, cooler and healthier. Not least, the water buffering in plants and soil reduces the peak load on the sewage system – unless the rain loads are so heavy that plants and soil cannot absorb any more water.

If the green roof does not have a controlled water retention system, the excess rainwater will flow unrestrictedly into the public sewage system. However, the right roof drains can retain water in case of heavy rain, thus reducing the load on the sewage system within the roof drain regulations.

When installing the drain the perforated part is wrapped in geo-textile to keep the soil away from the drainage system.

BLÜCHER® offers a full range of drainage solutions in stainless steel for green roofs.
