What is a green roof?
Green roofs, or living roofs, are roofs that are completely or partially covered with plants and vegetation – essentially a living green space where wild plant-life can flourish.
How do green roofs work?
Green roofs bring together specific parts in a system to successfully sustain a variety of vegetation:
- Primary waterproofing layer – this protects your structure from water damage
- Root barrier – protects against any roots that might grow through
- Green roof drainage membrane – this acts as a drainage layer so that your plants/vegetation don’t get waterlogged
- Growing substrate – supports your plants
- Vegetation layer – e.g. sedum blanket or wildflowers
What are the different varieties of green roofs?
Green roofs come in different varieties. Here’s some of the most common types:
- Extensive green roofs require minimal maintenance and are constructed using a low layer containing grass, moss, sedum or wildflowers. This lightweight solution provides excellent coverage, making it ideal for retrofitting or refurbishment projects.
- Intensive green roofing is a more complex option – they’re designed to support larger plants such as bushes and small trees which is why they’re often referred to as roof gardens. You’ll be able to effectively and naturally control the effects of heavy rainfall, improve your home’s insulation and even help to lower urban air pollution and temperatures.
- Biodiverse green roofing is designed with wildlife in mind – roofing advisers will help you choose the plants and natural flora that’s best for both you and integrates well into your local environment.
What are the advantages of green roofing?
Green roofing offers several ecological and environmental advantages:
- Green roofs increase biodiversity in urban areas – they offer a protective space for wildlife and nature to thrive without interruption from outside forces.
- Green roofs can promote energy efficiency – they provide thermal protection and reduce the need to cool or heat living spaces, which is great for energy costs.
- Green roofs offer special protection from flooding – water is processed by the green roof and discharged slowly to the gutters and downpipes over a longer period of time giving the rainwater system a chance to get rid of the water.
- They also help purify this water by preventing pollutants from passing from the atmosphere into other streams and water channels.
