The concept of extensive growth on roofs aspires to individuals with foresight.
Its fundamental benefits are: -

1. To forgo ever increasing utility costs.
2. The prevention of flood damage.
3. Preservation of the building’s envelope with the results of reduced maintenance costs.
4. Combating the heat island effect, the result of too many heat-absorbing roofs in close proximity.

Roof structures with minimum 100kg/m2 dead load capacity can be “greened” with one of Green Roofs International extensive planting concepts.

Its implementation is achieved by careful evaluation of prevailing climate conditions and an assessment of suitable, locally occurring flora or possible exotic variety for suitability and inclusion in planting schedules.

Typically, suitable plants are drought tolerant.  Coastal [salt spray tolerant] or desert grass, ground covering Australian or exotic species are integrated in our specially formulated plant growth stratum.

The integration of a slow release dripper system supplied from harvested rain water storage tanks will maintain the plantation during dry periods.

In Summary: -

1. Maintenance of Green Roofs International extensive green roof concepts is generally low;
   
   
2. In addition to the naturally occurring thermal insulation properties achieved by the extensive green roof concept, installation of thermal insulation boards will further reduce energy costs .

Safe access to roof areas with low parapet walls at roof perimeter; Green Roofs International supplies a range of maintenance personnel safety equipment or a range of proprietary and fully integrated public protection rail guard systems as part of our extensive green roof concept.
