Is Green Roofing Just A Fad Or Does It Have Real Benefits?
A green roof, also referred to as a rooftop garden, involves adding or extending a building’s roof to grow plants. In addition to enhancing the aesthetic appeal of a building, green roofs are environmentally friendly and energy-efficient. These roofs are typically covered with vegetation and have waterproofing features to protect the structure from damage. This trend has been gaining popularity in both urban and suburban areas of Pakistan in 2021, and in this blog, we will discuss how it is expected to continue in 2023 due to the numerous benefits it offers.
Green roofs offer many benefits beyond just enhancing the appearance of unsightly rooftops. Let’s explore the advantages of this growing trend and why you should consider joining the movement.
Green roofs lend environmental benefits;
Temperature control is a natural process that occurs throughout the year, but flat roofs are not capable of achieving it. The temperature in Pakistan rises steadily every summer, causing discomfort. Flat roofs are known for absorbing heat during hot days and releasing it during cold days, making them inefficient in regulating temperature. The main advantage of green roofs is their thermal performance, as they help to decrease the amount of heat that flows through the roof. As a result, less energy is needed to heat or cool the building, which can significantly reduce energy costs. External insulation is more effective than internal insulation.
A green roof provides an extra layer of protection for a flat roof as the plants act as a barrier against various environmental factors such as UV rays, extreme temperatures, wind, rain, and pollution. This natural shield enhances the durability of the roofing material and prolongs its life. In addition to environmental benefits, a green roof also saves money on re-roofing expenses by reducing the frequency of repairs or replacements. By opting for a green roof installation, you are not only contributing to environmental conservation but also safeguarding your roof against natural elements.
A major source of pollution and disturbance is noise, which can be a hindrance to concentration and relaxation. The noise level in Pakistan’s major cities has been rising, making it difficult to avoid external sounds such as traffic or airplanes. A green roof helps reduce noise pollution by providing an extra layer of vegetation that acts as a sound barrier, creating a quieter environment within the building. Studies suggest that a green roof can absorb up to 30% of environmental noise pollution, resulting in better sleep and an improved quality of life.
Green roofs are not only environmentally friendly but also visually attractive. Concrete or glass roofs are no longer considered appealing. Green roofs are the new trend and they enhance the look of both multi-storey buildings and small homes. By adding vegetation to the roof, the building’s aesthetic appeal is greatly increased. In Pakistan, people who are looking to build luxury homes prefer visually appealing architecture, and green roofs are an important element in achieving that goal.
The major cities of Pakistan are increasingly turning into concrete jungles, lacking vegetation and plant cover, resulting in high levels of pollution, smog, and increased amounts of carbon dioxide and other harmful pollutants in urban areas. Installing green roofs can make use of unused space while improving air quality by absorbing carbon dioxide and other pollutants and releasing oxygen. With a green roof, you can contribute to purifying the air and improving the environment.
Green roofs offer not only environmental but also economic benefits. The primary economic benefit of a green roof is that it can decrease a building’s operational expenses by providing better insulation, leading to lower heating and cooling expenses. In addition to promoting health and air quality benefits, a green roof can significantly enhance the value of the property, particularly in metropolitan areas with minimal green space. While installing a green roof involves higher upfront expenses than a traditional roof, the vegetation layer can protect the roof from UV rays and other environmental factors, resulting in a longer lifespan than a standard flat roof, which typically lasts 15 to 20 years.
Installing a green roof in your home is not only a positive step towards improving the environment in Pakistan, but it can also enhance the value of your property while lowering energy expenses. To achieve your objectives effectively, you may want to seek guidance from home architects and designers.
