You need to take the necessary tests and weight assessment checks, once they have been made then the installation of a green roof top can begin.
Layers- In Order
• A first layer of root barrier is installed. The most important factor in installation is waterproofing and protecting the membrane. The root barrier and an extra drainage sheet ensures protection
• Once the area has been covered work on the drainage system can begin. Around the perimeter of the area to be filled you must add a 12 inch vegetation free zone by adding gravel, also around any other areas on the roof that are not be covered . An aluminum drainage plaques are placed around the exterior of the zone
• On the base of the installation you can now add guttering or conduits. These can be directed to larger conduits which are ideal for rain water use at a later stage. Remember many plants and soils can be used to slowly release captured rainwater back once it has been trapped by the soil. Once the conduits are in place we can add recycled rubber panels or pavers.• Now you can add your soil or green media. This needs to be around 4 inches thick. Growing media is available on the market and is similar to soil although it has many advantages. Firstly it is lighter (around half the weight) and it can be supplemented with other lightweight minerals and organic components.
• You can now add pebble tiles, these tiles act a weight to stop lifting in high winds and can be made into square pieces which can be easily assembled.
• You can now start thinking about planting your roof, use your strips to create the desired design and effect. You can choose from a large variety of plants or grass and consult your local plant dealer for suitability.
