Frequently Asked Questions
What is a green roof?
A green roof (also known as a vegetated roof, living roof, or ecoroof) is a layered system of components including vegetation on top of an existing roof deck. A green roof can either completely or partially cover a rooftop depending on the desired goals of the project.
What are the benefits of green roofs?
Green roofs provide a wide array of environmental and economic benefits. Green roofs absorb rainfall and reduce the flow of stormwater runoff, double or triple the life of rooftop waterproofing membranes, insulate buildings, sequester carbon from the air, mitigate urban heat islands, and create habitat for beneficial species such as honey bees.
