Green Roofs: Open for Tours
Posted by Joyce Benson 1 Comment
Share this on:Green roofs are built right into a roof system and composed of a “high quality water proofing and root repellant system, a drainage system, filter cloth, a lightweight growing medium and plants,” according to GreenRoofs.org. These planted roofs are beneficial in many ways, from stormwater management and reduction of a building’s energy usage to cleaning the air and providing habitat for birds, butterflies and bees.
Some green roofs are intensive, with soil depths to about 15 feet, and allow for the planting of trees and other plants, as well as architectural features such as benches and fountains. Extensive green roofs are less expensive and lightweight systems which support drought-tolerant grasses, sedums and perennial flowers.
Where can you see these cool roofs? While there are many green roofs built every year in the U.S., only some are open to the public for viewing. Here’s some of the best:
- California, San Francisco: Visit the Academy of Science rooftop (pictured here) to observe the densest concentration of native wildflowers in the city.
