Following years of development and expansion, green spaces are diminishing from our urban landscape. With the added pressure of taller buildings causing reduced airflows in built-up areas, and heavier road traffic adding to pollution, designers and specifiers are now choosing to utilise roof spaces to address this eco balance.
There are three types of green roofs; extensive, intensive and biodiverse.
Extensive green roofs typically have shallow soil layers supporting moss, herbs and grasses where minimal maintenance is required. Intensive green roofing systems are effectively gardens on roofs, complete with shrubs, trees and walkways and come with all the garden tending usually associated with gardens – some will also include extensive irrigation systems. Biodiverse roofs are much more varied and balance both fauna and flora to replicate the ecological needs for the local area, again requiring minimal maintenance.
