Did you know that London is an average of 10 degrees warmer than other cities in the UK? Imagine if we had green roofs on every building in the city, the temperature of our city would reduce and lessen our impact on our fragile planet. Sedum absorbs the heat, it doesn’t bounce the heat back into the atmosphere. The plants are also air purifying, afford insulation, they help mitigate flood risk, encourage biodiversity, reduce air pollution and the urban heat island effect and also prolong the lifespan of the roof covering. One amazing fact I learnt today, was that they also increase the efficiency of solar panels, with a 5% gain as they stop the UV rays hitting and damaging the roof. Liv Eyres from Sedum Green Roof who will also be at Planted Country 9-11 June 2023 at Stourhead in Wiltshire, shares with us why they make for good habitats for biodiversity and so much more.

A sedum roof is essentially an additional layer on top of a finished waterproof roof. Little plants nestle in a tray, sitting in healthy (peat-free!) soil, on top of filter fleece and a drainage layer.
