Roof Gradient |
Problems |
Solutions |
Steep 5-20° (9-36%) |
· Runoff increases with roof gradient · Water runs off too quickly on steep slope, growing substrate can become dry especially near the top of the roof · Risk of sliding of green roof materials on the roof at high gradients |
· Use thin profile Enkadrains (0.25”) to slow down runoff and allow time for the rain to soak into the growing substrate · Use EnkaDrain&Retain to retain water and compensate for higher runoff
