The city is getting hotter day by day. What measures do you take to minimize the heat? Is there any? You can contribute to the city by making a green roof. Yes, the rooftop garden is the most important way to make the city different and cooler. The benefits of rooftop gardens have no limit. Continue reading to learn more.
Rooftop Gardens can give you the Following Benefits:
1. Bring Happiness
Imagine you’re at work and decide to leave for lunch. You take the lift to the top level and emerge in a magnificent park with breathtaking views. Doesn’t sound so horrible, does it? Rooftop gardens give access to nature in areas where it is considered a luxury, such as densely populated cities.
According to a study conducted by the University of Exeter Medical School, regular interaction with nature and green spaces in metropolitan settings might assist to maintain mental health and happiness.
Furthermore, because roofs minimize pollutants and improve water and air quality, demand for health care and stress may decrease.
Less stress also means happier and more productive employees, which makes staff recruiting simpler for businesses.

2. Better Air Quality
Rooftop gardens help to reduce and filter polluted air particles and gases, not only through the plants and photosynthesis process, but also by deposition in the growing area.
Green roofs may also assist minimize dust dispersion in the air and smog generation, resulting in lower greenhouse gas emissions in cities.
It is crucial to note, however, that while one green roof in a city may not have a significant influence on its own, a greater number of roofs in a city may have a noticeable beneficial impact.
3. Reduced Waste
Rooftop gardens have the ability to reduce waste by extending the life of the building’s components and technology. This can involve the use of waterproofing membranes on the roof as well as reduced usage of heating, ventilation, and air conditioning systems.
4. Effective Utilization of Rainfall
Rain is free water and energy provided by the nature, and rooftop gardens are ideal for maximizing its benefits.
Plants on green roofs absorb rainwater instantly, and the excess is sometimes saved for later use. Rooftop gardens may retain up to 80% of rainfall in summer and up to 40% in winter. After being consumed, the water is returned to the atmosphere via transpiration and evaporation.
Plants atop rooftops not only store rainfall but also assist to regulate its temperature, functioning as natural filters for any water that flows off the structure. However, rooftop gardens reduce the likelihood of water runoff, lowering the impact on the city and the potential of local flooding.

5. Controlling the Effects of Urban Heat Islands (UHI)
One of the most striking and crucial benefits of rooftop gardens is their good impact on the Urban Heat Island effect.
The UHI notion is based on the higher temperatures experienced in almost all metropolitan locations. Because the sun warms concrete faster than plants and trees, and because concrete is more prevalent in metropolitan areas, the city becomes a large hot-aired region (heat island) all year. This makes cities exceedingly hot in the summer, necessitating increasing usage of air conditioners and other cooling technology.
This impact reduces as the number of green areas in a city increases. Plants may chill large cities with their daily evaporation cycle, minimizing the UHI effect. Furthermore, the plants will cover what would have been a concrete rooftop, which is one of the leading sources of UHI.
6. Energy Efficiency
Rooftop gardens can also result in reduced and more efficient energy consumption. They provide excellent insulation, preserving heat in the winter and keeping temperatures cool in the summer.
This translates to fewer air conditioning systems being used in the summer and fewer heating systems being used in the winter, resulting in energy and, ultimately, cost savings.
In fact, a research released by the National Research Council of Canada revealed that rooftop gardens may alter temperature variations, regulate heat flow through the roof, and lower the energy consumption for air conditioning, particularly during the hotter seasons of spring and summer.
7. Urban Agriculture
With rooftop gardens comes another ecologically favorable and thriving initiative: urban agriculture. This entails converting green roofs into small farms that generate fresh food.
8. Reduced Noise.
Rooftop gardens offer insulation for both temperature and noise. Soil and plants can help absorb, reflect, or deflect sound waves, resulting in good noise reduction in the structure, particularly for low-frequency noises.
This might be extremely effective in reducing noise pollution in congested cities or places near airports or beneath aircraft routes.
9. Space for Wildlife
Aside from the various sorts of shrubs, trees, plants, and invertebrates that rooftop gardens may gather, they can also serve as a suitable home for many birds and a stopover for migrating species, allowing two distinct types to come into touch.
Summary
If you have a building roof, you can make it green with a garden. You know what the benefits of rooftop gardens are and how it can help the wild life and human life too. To keep the city cooler and provide shelter to the wildlife, you can make a garden there.
