Summary: Laying a green roof, flat or pitched to improve thermal insulation, alleviate flooding and reduce noise.
A Green Roof is a roof, flat or pitched, which is covered with living vegetation of some kind. This vegetation is laid over a waterproof covering to keep the water from entering the property.
What are the benefits of a Green Roof?
There are two main types of Green Roof although a third is a mixture of the other two.
Intensive Green Roofs: These are roofs which require fairly intensive maintenance. The soil is deeper than an extensive roof and the vegetation is usually larger or more intense. Intensive Green Roofs can hold larger plants and small trees etc and are usually for larger buildings and, again usually, allow for access, walks etc. A good use for an Intensive Green Roof is a herb garden.
Extensive Green Roofs: Extensive roofs require the minimum of maintenance and are laid on a much thinner layer of soil. The plants used are usually of the Sedum species which are very hardy with water storing leaves. The extensive way of laying a Green Roof is excellent for a DIY Green Roof and it is the Extensive kind of Green Roof which is found on most domestic properties.
DIY Green Roofs can be surprising easy to create. A rubber sheet is laid on the roof first. This sheet is called an EDPM sheet (Ethylene Propylene Diene M(class rubber) and is hugely weather resistant. Just as well as it spends half of it's life under water!
Then edging strips are laid to stop any soil or vegetation washing into the gutter or onto the ground in bad weather.
The vegetation mat supplied by Permaroof UK is a recycled (CFC free) mat profiled with integrated clay minerals and plant feeding elements which act as slow release fertilisers. The mat offers structural protection as well as filtering out pollutants. It also stores large volumes of water.
An extensive substrate soil is then poured over the vegetation mat. The substrate contains many organic elements needed in ecological cycles. A 40 litre sack of substrate mix will cover an area of 1 square metre at 40mm deep. This is the ideal depth for an extensive Green Roof.
The Sedum shoots are then sown into the substrate mix. Many green roofing companies supply Sedum in a mix of 5 to 10 different types of seed for extensive Green Roofing. The shoots are scattered evenly over the leveled substrate and the roof is watered. No further maintenance required!
There are many companies on the market that supply green roofing materials so that you can make your own, but if you would like the job to be done professionally simply contact them for a quote!
