Green Roofs

Green roofs are becoming more popular as an environmentally friendly roofing material that is also great to look at and helps with conservation of the surrounding wildlife. A correctly laid green roof will protect the underlying roof as well as being a stunning focal point. 

 

The benefits of a green roof over a traditional type roof are many. Green roofs can absorb up to 70% of rainwater fall, they are a key part in helping with climate change as the plants absorb damaging CO2 emissions.  

 

To lay a green roof firstly you have to have the correct type roof i.e. a flat roof (not over 45̊), a pitched roof will not be suitable for obvious reasons!

 

We start by ensuring the roof is free of leaks and damage and then lay a waterproof barrier over the roof. This is followed by a vegetation mat which acts as a reservoir of water for the plants and foliage.

 

This vegetation mat is followed by a layer of aggregate substrate which is a highly porous organic matter that provides ideal growing conditions for plants.

 

The final stage is the green roof itself. This can be laid as mixture of plants and foliage that sewn as seeds that will grow into an established green roof within 2 to 6 months dependent on the type of plants and foliage used.
