|Green Roofs love rain|
In fact, the Jacksonville and other areas of Florida and the Southeastern US, such as Houston and others are experiencing long term serious drought.
So when rain visits here, the green roof systems and plants must take advantage of every precious drop of water.
Last night we received about 15mm of rainfall, a little over one half inch. Since all of our green roof systems are shallow in depth, I was confident the plant roots had an opportunity to adsorb a good amount of water.
Curious though to just how much water some our potted plants received, I ventured out into the nursery and selected a plant potted up in a one gallon container and removed the plant, examining the rootball for moisture.

Horizontal roof architecture for green roofs has advantages, particularly if the green roof lies in the hot and dry climates of the world. Horizontal root architecture is discussed here.
So though shallow roofs may not be the answer for all green roof applications, they have established themselves as viable alternatives in hot and dry climates, providing lightweight potential, lower cost, beauty, habitat and stormwater attenuation.
