What does ecological roofing entail?
A green roof (GR) serves as a foundation for different plant life to flourish on top of a building. The covering is made up of layers, each of which has a particular purpose.
The base layer sits on top of the substrate and provides the building with a waterproof seal. Metal tray roofing services or a synthetic membrane could be used to achieve this. A drainage layer is added to allow water to exit the roof, followed by a filter and root protection layer.
Extensive Green roofs

The plant medium weighs between 60 and 150 kilogrammes per square metre. Where there is little to no human foot traffic and low maintenance roofing is required, eco roofing is used. And it is the cheapest method of roofing.
