Installation Process of Living Roof Trays
Preparing the Roof for Living Roof Trays
Before installing Living Roof Trays, adequate preparation of the rooftop is paramount. First, it is crucial to assess the structural integrity of the building to ensure it can support the additional weight of the trays, plants, and soil. An engineering evaluation may be necessary to determine load limits. Once structural considerations are addressed, the roof should be cleaned, removing any debris, dirt, or old roofing materials that could affect installation.
Next, a waterproof membrane must be installed to prevent water damage to the building. This membrane is typically layered with a root barrier to stop plant roots from penetrating the roofing materials. Some installations also require a drainage layer, which helps excess water flow away from the trays, preventing root rot and ensuring optimal plant health. It is vital also to install an irrigation system if necessary, ensuring plants receive water according to their needs.
