In summer, green roofs can retain 70–80% of rainfall and in winter they retain 10–35% depending on their build-up (Green roofs benefits and cost implications, Livingroofs.org In association with ecologyconsultancy, March 2004). Roof gardens reduce the load on the stormwater management system. Green roofs filter particulate matter from the air, retain and cleanse storm water and provide new opportunities for biodiversity preservation and habitat creation. A green roof has many benefits at economic, ecological and societal levels. The wide variety of benefits include environmental, economic and even social advantages. A green roof provides a rainwater buffer, purifies the air, reduces the ambient temperature, regulates the indoor temperature, saves energy and encourages biodiversity in the city. Green or living roofs are roofs that facilitate the growth of shrubs, trees and other vegetation. Airborne particulates tend to get trapped in the surface areas of the greenery.

A roof garden replaces some or all the vegetation that was eliminated. They can be on a flat or sloped roof. Green Roofs are an attractive roofing alternative to traditional roofing materials, such as a bare membrane, gravel ballast, shingles or tiles. The urban heat island is the overheating of urban and suburban areas, relative to the surrounding countryside, due to increased paved, built-over, and hard surface areas. Life cycle costing data which includes the cost of deferred maintenance and replacement suggests that green roofs cost the same or less than conventional roof systems. European evidence indicates that green roofs will easily double the life span of a conventional roof, and thus decrease the need for re-roofing and the amount of waste material bound for landfill. A green roof can provide an outdoor garden area that is sometimes not otherwise possible in urban areas.

This can be a major concern in urban areas, where the density of buildings can be high. In the summer, green roof planting shades the building from solar radiation and, through the process of evapo-transpiration, can reduce, if not eliminate any net heat gain. Green roof vegetation brings rooftop temperature down to ambient air temperature. Shading the outer surface of the building envelope has been shown to be more effective than internal insulation. Another important benefit of green roofs is their ability to reduce and slow stormwater runoff in … Benefit: Green roofs are energy efficient. The more rainwater retained is the less stormwater that runs off. On hot summer days, the surface temperature of a vegetated rooftop can be 10 degrees cooler than the air temperature, whereas the surface of a traditional rooftop can be up to 20 degrees warmer. What's more, people are happier in a green environment than in grey surroundings. Specialty waterproofing contractor, Mackintosh, provides raincoats for buildings and structures.

Green roofs filter particulate matter from the air, retain and cleanse storm water and provide new opportunities for biodiversity preservation and habitat creation. The excess of stormwater can cause flooding in some areas if not properly managed. In Frankfurt Germany, for example, a street without trees had an air pollution count of 10-20,000 dirt particles per liter of air and a treed street in the same neighborhood had an air pollution count of less than a third of that amount.

Conventional roofs are a large source of building heat loss in the winter and heat gain in the summer. Green roofs reduce the heat flux through the roof, and less energy for cooling or heating can lead to significant cost savings. I remember being in Chicago and looking down at a few green roofs from my hotel room. Green roofs go beyond any other roofing option when it comes to the multitude of benefits they provide to those who own, work and live under them. Storm water retention rates are determined by saturated infiltration capacity, thickness of the growing media, field capacity, porosity, under-drainage layer water retention and flow, and relief drain spacing. Although installation of a green roof usually involves higher upfront costs than a traditional roof, there are many economic benefits that can make up for this. 1. A green roof’s plants remove air particulates, produce oxygen and provide shade. In the cooler season, the additional insulation provided by the growing medium helps to decrease the amount of energy required to heat the building. In air-conditioned buildings, this could reduce the load and the energy required to power them. In a similar vein to the point above, green roofs reduce the need for air conditioning, whilst also ensuring less heat is required for the winter. Green roofs — also known as ‘vegetated roofs’ or ‘living roofs’ — are ballasted roofs consisting of a waterproofing membrane, growing medium (soil) and vegetation (plants) overlying a traditional roof. This in turn helps to cool the surrounding area, as well as decreasing the amount of energy required to cool the building. The benefits include increased energy efficiency (from cooling in the summer and added insulation in the winter), longer roof membrane life span, sound insulation and the ability to turn wasted roof space into various types of amenity space for building occupants. Green Roofs Communicate Company Values. But green roofs also have other benefits that you might not be aware of.
