Traditional roofing is made to shed water as fast as possible from the Roof Garden. Conversely, green roofing actually holds water on the roof. It may also make maintenance more challenging and can cost approximately 50% more to install. So why would you think of building a green roof?

Precisely what is ecological roofing

An eco friendly roof (GR) offers a base on the top of a structure in which various plant life may grow. Recent GR progress has been developed in Germany. About 10% of the buildings in Germany are green. The covering is built up in layers, each layer fulfilling a different function. The base layer sits along with the substrate and provides a waterproof seal for the building. This might come in the form of metal tray roofing or perhaps a synthetic membrane. A drainage layer is put into allow water to evacuate the rooftop, accompanied by a filter and root protection layer. The main protection membrane prevents plant growth from puncturing the waterproof membrane and causing leaks. The ultimate layer is definitely the growing medium in which the plant growth is bedded. Green or “living roofs” may be divided into three main categories. Extensive, Intensive and Bio diverse.

Extensive green roofs

Extensive GR, (also referred to as Eco roofing) can be used to advertise the expansion of mosses, herbs and grasses. The growing medium is comparatively shallow using a depth of between 60-200mm. The body weight of the plant medium is 60-150kg per square metre. Eco roofing is utilized where there is little or no human foot traffic and low maintenance roofing is necessary. This kind of roofing is the cheapest to put in.

Intensive green roofing – Roof gardens and park gardens are constructed using Intensive green roofing. This class of roofing offers the widest variety of planting opportunities. Shrubs, flowers as well as trees could be utilised. The depth of the growing medium is between 150-400mm. This pushes the body weight per square metre approximately 180-500kg and requires a substantial structure to back up it.

Bio diverse green roofing – Bio diverse roofing is designed to be left alone to reproduce an organic ecosystem. Soil levels on the surface are varied to create a wide range of different habitats for many different species. Local plants are grown and wind swept seeds are permitted to take root. Bio diverse roofing is frequently targeted at providing a specific habitat to get a threatened species.

The rewards for the building – Green roofing can make an unattractive urban roof into an great looking feature. Along with the aesthetic value added, living roofs provide numerous financial benefits. The waterproof membrane on roofs is subjected constantly to Ultra Violet light. These Ultra violet rays break down the top of the roofing causing leaks and the requirement for early replacement. The growing medium of living roofs offers a protective layer preventing damage from your sun. This can double the life span from the roofing and recoup the primary extra expense of installation. Further, green roofing supplies a thermal layer keeping your building cooler in summer and warmer in the wintertime. Planners within local government have now realized the benefits of ecological roofing. Many district councils offer financial incentives to developers using green roofing on new buildings. This trend continues as the requirement to reduce carbon emissions increases.

The benefits for that environment – Urban roofs built with traditional roofing materials absorb the suns rays and emit them as heat. It has triggered the urban heat island effect. This effect is most noticeable during the night with urban areas being warmer than surrounding areas. Air temperature inside london is about 6 degrees higher at night because of the urban heat island effect. Green zjghhj fails to absorb the temperature radiation therefore the effect is mitigated. Thus, the requirement for air cooling could be reduced in hotter climates.

Mass urbanisation leads to high water run off and flooding. Huge regions of concrete and tarmac prevent the natural drainage of heavy rainfall. Green roofing absorbs between 50-75% of rainfall, gradually releasing it back into the environment. This evaporation process also cools the building reducing energy consumption and carbon emissions further.

Depending on the growing medium and the species present, green roofing can store approximately 239 grams of carbon per square metre. It possesses a valuable habitat for plants and insects as well as providing food for bee’s and seed eating birds. Ultimately ecological roofing replaces the green footprint removed from the building.

Modern roofing materials give a lighter, much easier to maintain choice for eco roofing. Lightweight mats and module trays allow localized maintenance without having to take the Roof Garden. Considering the huge financial and environmental advantages of living roofs, the near future for green roofing looks rosy.
