Benefits of a green roof
A green roof has many benefits at economic, ecological and societal levels. 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 roofs are part of climate-proof construction. What's more, people are happier in a green environment than in grey surroundings.
There is often little space for greenery in urban areas. An ideal solution for this is greenery on the roof. A green roof is not only appealing to look at, it also offers many other advantages, such as water buffering, temperature regulation, sound insulation, air purification and it also encourages biodiversity. It's not just a Sedum roof that can be attractive, have you considered herbs on your roof, or vegetation specially selected to attract bees and butterflies? We are happy to advise you about the best application for your project.
How to make a green roof
Making a green roof is relatively simple. It’s a case of building up the layers within a green roof system. There are a number of key components to green roof construction. These components are broadly similar whether it’s for a larger commercial intensive roof or a residential green roof.
Each element has a key role to play within the overall green roof system. We will take you through each element in turn, covering all of the green roof materials you’ll need to purchase.
