Green Roofs & Walls
Green roofs are not just for hobbits anymore. The logic of green roofs is becoming more apparent. We can minimize our bills while maximizing the beauty of the urban landscape. And every day it's becoming a little easier to live in a house that just happens to have plants growing on it.
Vegetated roofs, or green roofs have a layer of living plants on top of the structure and the waterproofing elements. There are really two types of green roofs, intensive and extensive.
Intensive green roofs often have a soil depth of a foot or more, and require substantial structural elements to support the weight of the whole roof. Intensive roofs can sustain a wide range of plant species and typically require a fair amount of regular maintenance. Because of the additional demands they impose, intensive roofs are much less common than extensive roofs.
Extensive roofs are much shallower, typically only 2 to 4 inches deep, and are planted with particularly hardy plants. Over the last 50 years or so, this kind of roof has been developed, especially in Europe. But now they are becoming increasingly common in the United States.
