Green Roof – Extensive Shallow Pitch
An EXTENSIVE GREEN ROOF on a shallow pitch (typically defined as 0° to 15°) is a lightweight, low-maintenance ecological system designed for biodiversity and stormwater management.
These roofs are characterised by a shallow substrate depth (50mm–150mm) which keeps structural loading low, usually between 50–150 kg/m² when fully saturated.
