Viking Roof Garden System

The focus on improving the quality of life in our urban environments and reducing the impact on our buildings, can be assisted with the installation of a Viking Roof Garden System. A roof garden is a roof that is partially or completely covered with vegetation and soil; lined by a membrane that ensures the living space below remains watertight.

As compelling as the idea of a roof garden can be, there are several facets that must be executed correctly to ensure a successful roof garden installation. A dead roof garden, or worse-still, a leaking one is a hugely expensive issue to resolve.

Key factors include:

  • An appropriate waterproofing membrane layer
  • Only trained applicators installing that membrane system – (to the manufacturer’s specification)
  • Proven roof garden drainage components that have been sourced from the same reputable manufacturer
  • The soil (a.k.a growth medium) having been specifically formulated for roof gardens eg: high draining soil full of pumice, compost and perlite
  • Plants and grasses that aren’t too thirsty and don’t possess aggressive root structures
  • A maintenance programme employed, or better still, proprietary watering system
