Roof Garden

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.

Helping improve the quality of life in our urban environments and reducing the impact on our limited resources; a Viking Roof Garden System is designed to do just that: offer both functional and aesthetically appealing benefits.

Viking's Roof Garden System is New Zealand's only BRANZ Appraised green roof system.

The Viking Roof Garden system offers both functional and aesthetically appealing benefits:

  • Reduces storm water runoff
  • Air and water purification
  • Protects roof membrane from climatic extremes
  • Sound and temperature control

  • Insulates and shades building

  • Provides a pleasant outdoor area

  • Utilises a buildings ‘5th wall’

  • Installed only by a Viking Approved Applicator

  • 20-year product warranty

  • BRANZ appraised (Appraisal No. 903)

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

Components of a Viking Roof Garden System

  • Waterproofing membrane (Enviroclad or Anti-root torch-on)
  • Root Barrier* Drainage Board Composite (including protection fabric, drainage board cups and moisture retention layer)
  • Plants and soil
  • Aluminium drain protection box
  • Aluminium garden edging

Viking Roofspec understands that each roof garden is unique. We work with all project stakeholders to create a custom roof system that meets New Zealand Building Code requirements; the challenges of the local climate; and the needs of the building owner.
