Should you be considering a Sedum Roof?
More and more people are considering ‘sedum roofs’ for both commercial and residential new builds and this trend is starting to include timber, garden buildings and cabins.
But what exactly is a sedum roof?
A sedum roof, also known as a green or living roof is made up of a combination of soil, sedum plants with small pockets of air trapped between them. There are four basic components to the roof, a waterproof, root barrier membrane, a drainage layer, an aggregate layer and a vegetation/sedum layer. These are often supplied as ‘matting.’
The benefits of a sedum roof are wide ranging, they help alleviate flooding because they retain much more rain than a conventional roof, minimising the cause of some flooding and the pressure put on sewage systems. They can make a significant difference to climate change; research has proven that these roofs can reduce the amount of heat emitted from urban environments, which contributes to a greener, more ecological environment. And they provide an important habitat for wildlife.
However, we think you will love this benefit most of all; it will make your money go further!
Sedum roofs are known to provide insulation during winter and help reduce the need for air conditioning during the summer – saving on gas and electricity bills and let’s face it we could all use that!
Sedum walls are low maintenance but not no maintenance all will benefit from light watering if they are installed during hot, dry weather. The may also require weeding and feeding periodically.
And finally, did you know the largest sedum roof in the UK is at the Rolls Royce Car plant in Goodwood and has a 22,500 square meter (242,000 sq ft) living roof. Not quite as big but the world famous Poison Garden in Alnwick also has a sedum roof on its Arctic Cabin.
