Design the complete roof build-up
The vegetation, growing medium, modules, drainage layer and roof construction work together. Selecting one component in isolation can overlook how stored water, excess rainfall and structural loading affect the full system.
Combine storage with a reliable drainage route
Plants need access to moisture between rainfall or irrigation events, but excess water must still leave the root zone and roof safely. Both functions should be considered for the local climate, planting design and maintenance plan.
Confirm project-specific requirements
Structural capacity, waterproofing, wind exposure, fire requirements and drainage details are project specific. A qualified roof professional should confirm the build-up before installation and coordinate it with the planting and irrigation design.
