Increased Roof Membrane Life

Green roofs increase the longevity of a waterproof membrane by at least 2 to 3 times its average lifespan by protecting the waterproof membrane from:

UV rays, electromagnetic radiation and falling objects. (Cities, 2006)

Extreme temperature fluctuations in the summer: a black roof will fluctuate between 150ºF and 70ºF in 12 hours, while a green roof maintains a consistent temperature around 80ºF. (Kingsbury, 2008)

Freeze/thaw cycles during the winter.

Waterproof membranes without the protection of a green roof need to be replaced every 10 to 20 years while some green roofs in Europe are over 100 years old and still waterproof. (Earth Pledge, 2005)

This effectively helps reduce landfills by reducing the amount of membranes being thrown away.
