EXTENSIVE GREEN ROOFS
Extensive green roofs provide a light-weight, low maintenance, instant ‘green effect’ roof solution, and are the most common type of green roof we supply. Extensive green roofs are not usually intended for general public access, and are chosen mostly for their ecological benefits.
Typically, extensive roofs use a Sedum vegetation due to it’s ability to flourish in harsh environments, cost effective, and lightweight system requirements. Extensive green roofs can be designed into new buildings, or ‘retro-fitted’ onto existing buildings.
SEMI-INTENSIVE GREEN ROOFS
Our semi-intensive green roof systems include a richer, deeper substrate and drainage solution compared to extensive roofs, enabling use of a wider range of complex plant mixtures. Semi-intensive roofs are generally used within highly visible area’s to improve aesthetic design using small shrubs, forbs, and grasses. They require a higher level of maintenance compared to extensive roofs, due to the vegetation, and substrates used.
INTENSIVE GREEN ROOFS
Intensive green roofs are intended to replicate what can typically be found at ground level in the natural landscape, and in green spaces such as parks or cultivated gardens.
Intensive green roofs involve intense landscaping, and are suited to roofs with a highly visible presence or public access, and commonly referred as a ‘roof garden’. Choices include shrubs, native forbs and grasses, larger perennials, tropical, non-native vegetation.
