An Extensive Green Roof requires rather low or no maintenance,  planted with sedum which is highly adapted to the UK climate and is  designed to look after itself for the majority of the year.

A wildflower Green Roof is an extensive green roof but planted with a wild flower mix, a natural habitat for wild life. Creating a more attractive and colourful appearance.

The cooling affect of the green roof can actually improve the efficiency of solar panels. Research has shown that green roofs and solar panels are complementary. Photovoltaic cellsplaced over a green roof have a higher voltage output, and the environment for the vegetation below the cells are less stressful so habitat becomes more bio diverse.
