Roof gardens

Whether as a means to create additional living areas, as heat insulation or for the prevention of building damages roof gardens are an effective and attractive alternative to conventional building styles. We can inform you on the differences between extensive and intensive roof greenery as well as on available grants. For their planning, our experts take roof inclination and usage requirements into consideration, advise on the choice of suitable materials (root barriers, drainage, inspection manholes, plant substrates, turf tiles, sowing of shoots, suitable shrubs and hedging, etc.) and professionally execute the works. Maintenance is provided by our qualified gardeners.

In order to create additional open spaces and relaxation areas, many urbanites go through the roof!

Our experts will help come up with the optimal design for your roof and help you do the mathematics when it comes to working out load requirements and layer composition such as root layer, drainage course, filter layer, vegetation base layer, etc. They will assist in the choice of plants such as sedum succulents, spray sowing, low-growing plants such as alpines, vegetation mats, container plants, etc.

Our garden professionals are also happy to carry out maintenance of existing roof gardens.

Advantages of a Roof Garden

  • Increased water retention: even thinly layered roof gardens can retain more than half of rain water; water flows away slower and at the same time is filtered
  • Increased humidity, cooling and sound absorption
  • Binding of dust particles and pollutants
  • Extension of roof life
  • Thermal Insulation: lower k-Values (measure for energy transmission = lower energy loss)
  • Habitat creation for animals and plants and positive visual impact on urban environments
  • Natural fire protection
  • For these advantages the City Garden Department of Vienna are awarding grants of up to 2,200 Euros.

Extensive Roof Gardening

  • Usually used with ecology in mind, i.e. for the reclaiming of habitat for animals and plants.
  • Low maintenance costs (1-2 inspections per year)
  • Reduced nutrient and water requirements
  • Minimal erection height and load requirements
  • Low production cost

Intensive Roof Gardening

  • For roofs with a lot of active use by residents
  • Increased maintenance costs
  • High water requirement (irrigation system)
  • Erection height of about 20-80cm, high load demands (from 200kg/m²)
  • Higher production costs
