Traditional roofing is made to shed water as quickly as possible from the Modular Green Roof Trays. 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 by which various plant life may grow. Recent GR progress has become developed in Germany. About 10% from the buildings in Germany are actually green. The covering is built up in layers, each layer fulfilling an alternative function. The base layer sits on the top of the substrate and offers a waterproof seal towards the building. This may come in the form of metal tray roofing or a synthetic membrane. A drainage layer is added to allow water to evacuate the roofing, then a filter and root protection layer. The main protection membrane prevents plant growth from puncturing the waterproof membrane and causing leaks. The final layer will be the growing medium in which the plant growth is bedded. Green or “living roofs” may be split into three main categories. Extensive, Intensive and Bio diverse.
Extensive green roofs – Extensive GR, (also called Eco roofing) can be used to advertise the expansion of mosses, herbs and grasses. The growing medium is fairly shallow having a depth which is between 60-200mm. The load in 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 sort of roofing will be the cheapest to put in.
Intensive green roofing – Roof gardens and park gardens are constructed using Intensive green roofing. This group of roofing provides the widest range of planting opportunities. Shrubs, flowers and even trees could be utilised. The depth from the growing medium is between 150-400mm. This pushes the load per square metre approximately 180-500kg and requires a significant structure to aid it.
Bio diverse green roofing – Bio diverse roofing is made to be left alone to reproduce a natural ecosystem. Soil levels on the surface are varied to create an array of different habitats for different species. Local plants are grown and wind swept seeds are allowed to take root. Bio diverse roofing is often aimed at providing a particular habitat to get a threatened species.
The rewards for your building – Green roofing can make an unattractive urban roof into an great looking feature. And also the aesthetic value added, living roofs provide numerous financial benefits. The waterproof membrane on roofs is subjected constantly to Ultra Violet light. These UV rays break down the surface 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 could double the amount life span in the roofing and recoup the initial extra cost of installation. Further, green roofing offers a thermal layer keeping the building cooler in summer and warmer in winter. Planners within local government have finally realized the advantages of ecological roofing. Many district councils offer financial incentives to developers using green roofing on new buildings. This trend will continue as the requirement to reduce carbon emissions increases.
The rewards for the environment – Urban roofs designed with traditional roofing materials absorb the suns rays and emit them as heat. It has led to the urban heat island effect. This effect is most noticeable during the night with urban areas being warmer than surrounding areas. The environment temperature inside london is about 6 degrees higher at nighttime due to the urban heat island effect. Green zjghhj will not absorb the heat radiation so the effect is mitigated. Thus, the necessity for air conditioning might be reduced in hotter climates.
Mass urbanisation contributes to high water run off and flooding. Huge regions of concrete and tarmac avoid 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 property reducing energy consumption and carbon emissions even more.
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. Essentially ecological roofing replaces the green footprint removed by the building.
Modern roofing materials give a lighter, simpler to maintain option for eco roofing. Lightweight mats and module trays allow localized maintenance with no need to consider the Modular Green Roof Trays. Thinking about the huge financial and environmental benefits associated with living roofs, the near future for green roofing looks rosy.
