A living green roof brings a myriad of benefits – provided it is properly installed. It doesn’t matter whether you are building a bug hotel, a dog kennel or an extension to your home. The secret to a successful green roof lies in careful planning.
1: A green roof is an asset to any building
Besides looking visually amazing, green roofs have been proven to be good for the environment by helping pollinators, such as bees, and insulating your home. Another important benefit of green roofs is their ability to reduce and slow stormwater runoff in urban environments. Furthermore, they’ve also been scientifically proven to boost productivity of workers when used in a workplace.
2: Green roofing isn’t waterproofing
Make sure your building is watertight before adding a green roof buildup. All of the layers of a living green roof – the drainage, the water retention, the growing medium and the plants sit on top of conventional waterproofing.
3: A lightweight sedum roof weighs as little as 45 Kg per square metre but…
If you will EVER need to walk on the roof eg for maintenance or installation, allow for a weight of 120Kg per square metre. In general, I would advise anyone to err on the side of caution. It might sound extreme to bolster up your garden shed to that extent – but with any project, safety is paramount. Do you really want your shed to collapse when you go to feed your green roof?
4: You will need to have an edging on your roof to keep everything neat and in place
Edgings are available from www.fixfast.co.uk
5: Green roof kits make ordering easy
A green roof kit is a simple and reliable way of ensuring you have all the right components to hand. Enviromat green roof kits are available for pitched roofs and for flat roofs. The build-up is slightly different for each.
