A living roof or an “eco-roof” is commonly called when the roof surface is partially or completely covered with vegetation. A green roof is also called an “eco-roof” because it brings in a lot of sustainable advantages like heat moderation, reducing surface runoff, providing insulation, etc.
The last decade saw a lot of rapid urbanization in major parts of India and suddenly most of the working youth live in concrete jungles that have no or very little open spaces, forest lands, or recreational areas. When you construct a green roof with the help of certified and experienced professionals, your home will not only look beautiful but also will come to a step closer to responsible and sustainable living. In the current scenario of increasing global warming, we urge our readers to consider having a green roof and do their part for a better future.
You can install a green roof on both existing and new buildings. The installation of a typical green roof involves covering the roof surface with an insulation layer, a waterproofing layer, and a barrier against root infiltration. To make way for the excess water off the roof, a drainage system is spread over it. Soil or a growing medium is added on top of all the layers for the plants or vegetation to be planted and grown. Keep in mind to check for the structural integrity and strength of the roof to ensure it is capable of bearing the load.
Depending on the type of vegetation you are planning, namely extensive and intensive, the thickness of the constituting layers vary in both cases. We suggest having a certified professional for the installation and maintenance procedures. The plants or vegetation in your green roof can be selected according to your wish but our experts suggest getting a low-care system, especially if you’re a beginner because it can let you enjoy a green roof without thinking about the maintenance aspect too often.
If you’re still not convinced, we at HomeTriangle came up with some of the main advantages that could help sway your opinion.
1. Aesthetically Pleasing
One of the best things about green roofs is that they are so pleasing to the eye. They do a brilliant job at softening hard concrete borders and add to the curb appeal and property value of the home. The intermediate terraces and rooftops which might go unused otherwise can become soothing views of areas with the help of beautiful organic colors. Green roofs can also provide a fulfilling gardening and outdoor environment to homeowners with little or nonexistent garden areas. Additionally, living among plants can boost the positive spirits and well-being of the dwellers, making for happier and more relaxed homes.
2. Control Surface Runoff
Hard roofs are impermeable. But a green roof with its soil or substrates can absorb the falling rainwater and lower the rate of runoff. This will help in saving a lot of water that is otherwise left to drain into the sewers. With the proper knowledge and experience, a green roof can be integrated with a rainwater harvesting system and that will directly cut down issues relating to water pooling on roofs and lawns. The layers on the green roof will act as a natural purifier for the rainwater.
3. Acts as an Insulation
Heat gain and loss in your home happen mostly through the roofs. A green roof insulates the home from heat gain during the summer and heat loss during the winter by strengthening the thermal mass of the roof surface. A living roof will also considerably reduce the amount of noise getting through the roof as the uneven surface of the foliage and soil reflects and deflects outside sounds.
4. Reduced Energy Costs
Energy efficiency and sustainability in a home can be boosted significantly with a green roof. With reduced cooling and heating loads, the cost involved in operating and maintaining mechanical appliances is directly reduced.
5. Improves Air Quality
Plants are natural air purifiers. They consume carbon dioxide from the air and replenish it with oxygen. Some species can effectively deaden pollutants like dust and soot, and greenhouse gases like carbon monoxide, nitrogen oxide, CFCs, methane, ozone, and so on. Cleaner air, then, contributes to healthier living.
