green roofs

Vegetated building tops

Green roofs are rooftops covered with vegetation planted over a waterproof membrane.

They reduce urban heat, absorb rainwater, and provide insulation.

A building might have an intensive green roof with trees and walkways, or an extensive one with low-maintenance sedums: The city offers tax incentives for green roofs.

Also called living roofs.
