Vegetated roofs come in many shapes and sizes, from small inaccessible areas atop mechanical shelters to expansive landscapes over podium decks. Beginning at the structural deck, vegetated roof assemblies consist of waterproofing membrane, drainage and retention layer(s), filtration layers, engineered growing media, and plants. Engineered growing medias may range from as thin as a couple of inches, to multiple feet, dictated by building thresholds, design intent, and the type of plant material the vegetated roof is trying to support. Vegetation may range from sedums and succulents all the way two large mature trees, and everything in between.
There are three primary categories of vegetated roofs: extensive, semi-intensive, and intensive. The types are based on thickness of growth media, typically dictated by the type of vegetation intended to be used for the vegetated roof. Generally speaking, extensive systems include a growth media 3 to 8 inches deep; semi-intensive systems’ growth media is 8 to 12 inches deep; and intensive systems’ growth media is 12 inches to several feet deep. Extensive roofs can be constructed with layers or modules4.
