Green Roofing System, Hilton Head, SC
A green roofing system is an addition to an existing roof that includes high-quality waterproofing, a root repellent system, drainage, filter cloth, a lightweight growing medium, and plants.
This roofing system can be modular, with drainage layers, filter cloth, growing media, and plants fully prepared in movable, usually interlocking grids, or they can be freely laid/built-up, with each component of the system installed separately. Green roofs are green spaces that are “enclosed” on top of a man-made structure. The green space can be found below or above ground level, but it is always distinct from the ground. Green roofs have been successfully installed in countries worldwide and can give a variety of public and private benefits.
Green roofing systems not only offer a proven return on investment to building owners, but they also offer considerable social, economic, and environmental benefits, especially in urban areas.
Benefits of Having A Green Roofing System
It Can Enhance The Stormwater Management
Water is kept by the substrate on green roofs, then taken up by the plants, returning it to the atmosphere via transpiration and evaporation. As a result, green roofs may retain 70-90 percent of the precipitation that falls on them in the summer and 25-40 percent of the precipitation that falls on them in the winter.
Green roofs collect rainfall and help control the temperature of the water and serve as natural filters for any runoff. As a result, green roofs lower the amount of stormwater runoff and the time it takes for runoff to occur, putting less strain on sewage systems during peak flow periods.
It Reduces The Urban Heat Island Effect (UHI)
Plants on vertical and horizontal surfaces have the ability to cool cities during the hot summer months by utilizing the daily dew and evaporation cycle. This helps to lessen the impact of the Urban Heat Island (UHI) effect. Normally, the light absorbed by vegetation would be turned into heat energy.
UHI is also reduced by covering some of the hottest areas in the urban environment, like black rooftops or those that have materials that reflect heat.
Aside from reducing the spread of dust and particle matter around the city, green roofs can also reduce smog generation. This has the potential to contribute to the reduction of greenhouse gas emissions and the adaptation of metropolitan areas to a future climate with hotter summers.
It Helps Improve The Air Quality
Plants on green roofs have the ability to collect airborne pollutants, reduce atmospheric deposition, and filter toxic gases, among other things.
The temperature-regulating effects of green roofs have the potential to lower the demand for electricity from power plants, as well as the quantity of CO2 and other polluting by-products that are emitted into the atmosphere.
Green Roofing Systems Are Energy Efficient
Because green roofs provide superior insulation, they can lower the amount of energy required to maintain a building’s temperature. Roofs are the source of the most heat loss in the winter and the highest temperatures in the summer. Thus green roofs can help cut energy costs.
A study released by the National Research Council of Canada indicated that an extensive green roof lowered the daily energy consumption for air conditioning in the summer by more than 75% when used with a cooling system (Liu 2003).
It Increases Biodiversity
Green roofing systems can support a wide range of plants and animals, as well as provide habitat for a variety of birds. They can link species that would otherwise be fragmented by functioning as a stepping stone habitat for migrating birds. Increased biodiversity can benefit three domains: the ecosystem, the economy, and the community–as visual and environmental diversity can improve the community and psychological well-being.
Frequently Asked Questions
- How Does A Green Roof Work?
Green roofs absorb rainwater through the plants, drainage layer, and substrate layer. It prevents rainfall from entering the sewer system. They also help regulate the groundwater level by purifying rainwater and evaporating via the plants.
- What Do Green Roofs Solve?
Green roofs offer shade, absorb heat from the air, and cool the roof surface and surrounding air. Green roofs can help to mitigate the heat island effect, especially during the day, in cities, and other urban settings with limited vegetation.
- Do Green Roofs Need Drainage?
Drainage is critical in a green roof because it must be able to handle heavy amounts of water while still being able to deliver enough water for the green roof to flourish.
