Intensive Green Roofs
Intensive green roofs, which can be utilized as real roof gardens, are heavier, more costly, and demand more maintenance than their extensive counterparts.
Intensive roofs generally require an underlying roof structure with high load bearing capacity, in order to support the weight of deeper growing medium and larger plants. With a growing medium depth of 8" or more, intensive roofs can accommodate a wide range of vegetables, shrubs, and sometimes even trees. Intensive roofs will generally require regular care, particularly irrigation - though this will depend on plant selection.
Before beginning any green roof project, it is essential to consult with the proper building and design professionals.
