Greenroof Systems

System Types

Greenroofs generally fall into two categories—extensive and intensive—although there are many system variations, including modular designs in which the greenroof layers exist within pre-vegetated, moveable containers or grids. Explore the following Greenrise Technologies system types:

Extensive
Extensive greenroofs are more lightweight, with shallow buildups of six inches or lower. They may or may not be accessible and typically require less maintenance.

Intensive
Intensive greenroofs have a deeper system buildup, as determined in large part by plant selection, and are therefore much heavier. They’re usually designed to be accessible for a variety of purposes, so the design possibilities are endless—from decks and pathways to ponds and picnic areas. Intensive greenroofs require regular maintenance.

Sloped
A sloped, or pitched, greenroof is a type of extensive greenroof. Buildup depends on the degree of the slope, and considerations must be made in relation to greater plant exposure and potential for erosion.

Rooftop Gardens
A rooftop garden typically covers only a small part of a roof, and therefore weight considerations aren’t as relevant. Rooftop gardens are usually designed for decorative purposes only or small-scale food production rather than to address major issues such as stormwater runoff.

Living Walls
A living wall can do wonders inside and outside, from revitalizing a rundown building to bringing joy—and cleaner air—to employees in an otherwise drab office space. The most common type of living wall is composed of pre-vegetated modules attached to a wall or frame. Living walls are flexible in design—the modules can be made from a variety of materials and can accommodate many plant types.
