How To Prepare Your Rooftop For Terrace Gardening

There are multiple ways to get started with a rooftop garden. You can start with planting in simple containers – big & small, build raised beds, or cover your terrace with proper soil beds like traditional gardens. If you choose to build a fully planted green roof then you need to prepare your rooftop to prevent any potential damage to the building.

 

The new buildings are usually constructed keeping waterproofing in mind, unlike the conventional buildings. In this article, we are going to tell you about the layers that you’ll need to install on your rooftop before planting a fully covered garden.

Protection Layer

Mechanical strength to your rooftop, moisture resistance, and temperature control are a few of the multiple benefits provided by the protection/insulation layer. In most cases, the insulation layer is made of polyurethane foam, PIR panels, or XPS extruded polystyrene boards. It is advised to install PIR panels for rooftop gardens as they have milled edge connections and grooves that allow the rainwater to swiftly pass through the drainage systems.

Installing a protection layer for your rooftop will ensure the long life of your terrace garden and will keep all your worries away.

Drainage System

The purpose of installing a drainage system is to remove the saturated water as quickly as possible. A proper drainage system should quickly discharge the excess water from the vegetation layer and rooftop into the drainage system. 

The common drainage material includes – porous mats that can soak in the extra water, granular materials (gravels, stone chips, etc), lightweight plastic sheets, or polystyrene drainage modules.

To prevent clogging of the drainage system and keep the drainage layer separate from the plants, the filter layer is installed. It prevents the deposit of fine particles and keeps the drainage system functioning. Nonwoven or geotextile layers are ideal in most circumstances.

Vegetation Layer

The surface where you’ll grow your plants is called the vegetation layer. The growing medium (soil) will be prepared according to the plants that you choose to grow on your rooftop garden. Well-fertilized soil is best for rooftop gardening. 

The thickness of soil will again depend on the choice of plants.
