Semi-Intensive Green Roof Key Features

Posted by david.luukas

Blackdown semi-intensive green roofs provide the opportunity to increase the range of plant species used on the roof environment without having to specify an intensive system. Wildflower and drought tolerant planting can be used to great effect to provide increased bio-diversity and, at the same time, offer an aesthetically pleasing look.

Vegetation

A wide range of planting options is available, typically in the form of plugs, but can be larger if required. Drought tolerant wildflowers, herbs,
grasses and sedums are suitable, along with annual and specialist seed mixes that will replicate habitats such as chalk downland.

Key Features

Substrate

A Blackdown semi-intensive substrate is required for this range of plants. This offers good water holding capacity whilst still providing sufficient air and granulometric distribution to encourage strong root growth. Includes slightly lower levels of organic matter and nutrients than intensive substrates.

Waterproofing

Typical waterproofing options include suitable root-resistant bituminous membranes from the Derbigum and Euroroof ranges along with standing seam metal roofing.

Warranty

Warranties are available for the Alumasc waterproofing system used in the green roof build-up.
