The threat of climate change has seen a rise in homeowners looking at ways to cut carbon emission. Installing a green roof has many benefits to both your home and the environment. If you want to make your home more eco-friendly, your roof shouldn’t be neglected. This low-cost solution will liven up your home and help reduce your carbon footprint.
What is a Green Roof?
A green roof is a roof that is covered either partly or entirely with vegetation. The vegetation is grown over layers of waterproof materials. Anything that grows in containers on a roof is not a green roof. There are two types of green roofs:
• Extensive – the soil layer is 6 inches or less
• Intensive – the soil layers is greater than 6 inches
Green roofs are best suited to a flat roof on a home. When installing a green roof, the location needs to be structurally strong and have adequate access to water.
Installing a Green Roof on a New Home
Installing a green roof on a new building is ideal. Builders and engineers can work out what support structures are needed for the roof. Determining the location of a green roof early in the design process is necessary for the construction of the roof.
Installing a Green Roof on an Existing Home
Before you start planning your green roof, a structural engineer needs to inspect the roof. The added weight of a green roof can add a more than 100kg onto your home or garage. If your home is not suited for a green roof, new load bearings will need to be fitted.
Benefits of a Green Roof
A standard green roof will cost around $200-$400 per square metre to build. The cost of installation of a green roof will save you in the long run. As well as the financial benefits, the environment will benefit greatly. The benefits of a green roof include:
• Insulation – the added weight of your home will help keep it cool in summer and warm in winter.
• Stormwater management – rainwater runoff ends up in our storm water, which filters down to our waterways. Green roofs trap and absorb as much as 90% of the rainwater from our roofs. The remaining 10% is evaporated into the Earth’s atmosphere.
• Improved air quality – trees and plants absorb carbon dioxide and filter out gases. This decreases our reliance on electricity and reduces the amount of CO2 we emit.
• Edible – if you grow herbs in your green roof, you have easy access to them. Fresh, organic produce grown in your home will save you money and the taste can’t be beaten.
