A well designed green roof should outlast most other roof types since the rubber waterproof layer is protected by a layer of soil from UV exposure, hail, and the other forms of weathering that eventually destroy other types of roof materials that are exposed to the elements. Just make sure that no tree seedlings get established on the green roof. Also, if you want to harvest rainwater, the water draining from a green roof has been filtered by the soil on the roof.
