Award-winning green roofs

Pre-grown wildflower roof

All Organic Roofs specs are based on GRO Code guidance on green roof build ups, but we encourage deeper substrate depths wherever possible to increase biodiversity potential.

Ask us about our Habitat Upgrade package: a range of specially selected biodiversity hotspots for bees, butterflies and other invertebrates to improve the biodiversity contribution of whichever green roof you choose.
