Green Roof Categories
Our experience demonstrates that the most efficient designs for
the vast majority of American green roofs can be derived from five basic
green roof types. 
Roofscapes,
Inc. has developed a Roofmeadow® green roof assembly that satisfies each
of these types.
| Type I: | Roofmeadow® Flower Carpet and Roofrug™ |
| Type II: | Roofmeadow® Aromatic Garden |
| Type III: | Roofmeadow® Savannah |
| Type IV: | Roofmeadow® Meadow |
| Type V: | Roofmeadow® Heath |
The selected assembly depends in part on project conditions, including climate, desired plant community, specific performance requirements, and load bearing capacity of the roof deck. All assemblies will include the following elements: 1) protection of the waterproofing membrane from root and biological attach, 2) protection of the waterproofing membrane from physical abuse and accident, 3) a base drainage layer, 3) a separation layer to prevent fine-grained engineered soils from fouling or clogging the drainage layer system, and 4) an engineered soil to support the vegetation.
