Green roofing is a term that refers to a soil and vegetation system placed on top of some types of quality roofing systems.
When it comes to green roofing, there are two types, which are intensive and extensive.
Intensive green roof setups contain concentrated soil mediums that can support lots of different types of plans and vegetation, though such systems usually necessitate ongoing maintenance. Since intensive green roof systems have deeper soil, they can support larger vegetation – trees included. These systems often require structural reinforcements to accommodate the added weight.
Extensive green roof systems contain soil mediums that are typically half a foot or less. Such systems usually have drought tolerant vegetation and grasses since they are usually shallow rooted and need little maintenance.
Green roof systems, whether intensive or extensive, can be applied to the roofs of commercial/industrial facilities. While such systems can be setup on many types of roofs, roofs supporting intensive green roof systems may require further structural reinforcements to shoulder the additional weight.
Green roofing systems are an extension to roofs already in place. Installation requires sufficient water proofing, a drainage system, a root repellant system, a growing medium and vegetation.
Green roofing offers myriad benefits. For instance, there are reduced energy costs since the soil and plants of a green roof setup provide extra insulation and a natural cooling effect. It can also extend the life expectancy of the roof membrane upon which it is setup, lessen normal maintenance fees, lessen storm water overflow and enhance air quality.
