Green roof slope design. 15 45 roof angle appropriate measures to cope with shear forces and erosion green wall. Roof slope treatment volume is maximized on relatively flat roofs a slope of i to jr. However some slope is needed to promote positive drainage and prevent ponding and or prolonged saturation of the growing media. Pitched green roof design considerations.

While the basic components of a sloped green roof are similar to that of a flat system building teams must pay particular attention to water management erosion control and maintenance. There is no steepest pitch for a green roof they can even grow vertically. A recent trend is to adapt green roof technology for low and steep slope applications. As the popularity of vegetated roofs grows in the u s building teams are finding new methods for greening rooftops.

This means that you can have a green roof that s best suited for flat surfaces slanted roofs and more. However when dealing with a sloped green roof with a pitch of more than 9 5 you ll need a design solution for retaining water and ensuring the substrate stays in place.
