You’ve heard of rooftop gardens? Now there are rooftop farms, complete with chickens, starting to appear across the globe on sunny expanses of warehouse roofs.
Rooftop farming was born out of the green-roof movement, in which building owners cover roofs with vegetation atop special waterproof membranes.
The benefits are numerous to the building owner, as well as the community.
- provides insulation for the building
- keeps cooling costs down because the roof doesn’t get as hot
- absorbs storm runoff, particularly helpful during flooding
- adds more oxygen and absorbs carbon in the air
- creates a habitat for local birds, butterflies and bees
- brings color to an otherwise drab landscape
Rooftop farms take the green-roof concept a step further, with plots that provide fruits and vegetables for local residents and the chance for urban volunteers to become part-time farmers.
