Quick answer
Moving ordinary garden soil onto a roof can create weight and drainage problems. Rooftop growing media is typically engineered around a system rather than selected from a generic retail soil list.

Weight matters
The project structural design may place limits on saturated and dry media weight.
Drainage must match the assembly
Growing media works together with drainage layers, filters, irrigation and roof assemblies.
Planting depth affects formulation
Shallow extensive systems and deep planters create different root-zone conditions.
Specifications come first
Send the project specification, planting plans and required testing before assuming a stock mix is acceptable.
Logistics are part of the job
Bulk trucks, totes, crane coordination and rooftop placement planning can matter as much as the media itself.
- Specialty Soils can review rooftop and specialty specifications.
- Pumice is one lightweight mineral component used in some specialty formulations, but there is no universal rooftop recipe.
- Coordinate samples and approval before full production.
