From the ground up — the right flooring
Regardless of your design preferences and your favourite material, the floor on a roof terrace must have certain properties that make life easier for you and your plants. It should be hard-wearing and able to cope with you placing and moving heavy pots on it. It is also important for the floor to be waterproof so that no moisture seeps down into it and potentially causes serious water damage. Ideally, the floor should be slightly inclined so that rain and other liquids quickly run off into a gutter at the edge or into a drain.
And don't forget the structure. After all, a substantial amount of weight can quickly build up on a roof terrace due to the various plants and flower pots, planters and flower boxes. The substructure must be able to support and withstand this weight. We also particularly recommend fitting a practical water connection.
Planting your roof terrace — your charges need to survive in this environment
Life on a roof terrace or in a roof garden is tough for plants. After all, there are certain things that you expect from them given the location. Blazing sun, heavy rain, the freezing cold, strong winds
— they have to brave all this while still looking good. If you pick the wrong candidates then you will soon be pulling your hair out over bent, frozen, withered or drowned flowers. In the worst-case scenario, you will find that you need to replace or at least replenish the vegetation every season. This will frustrate you — and, of course, cost you money.
Ideally, you should therefore put a few safety measures in place for your fosterlings. Only plant them in containers that have a drain hole, for example. Avoid using mats as far as possible. This is because if there is a longer period of heavy rain, the water will collect in the container and cause waterlogging. Nevertheless, you do need to water certain plants regularly and diligently — possibly even several times a day, depending on the weather.
To prevent plants from quickly drying out, create a wind shield for delicate plants — either using artificial material or other, taller plants. During the winter, plants that are sensitive to frost need a suitable pot or planter and insulation made from reed, raffia mats, bubble wrap or a similar material. Otherwise, you will need to set up winter quarters for them. Weight is also a factor to consider when transporting the plants to their new home.
Although it may seem like it now — there are few limitations when it comes to adding greenery to your roof terrace. Many plants are virtually made for life in the clouds.
