Another green roof hack – a customers project – a capable roofer built this for his young son ….its in the middle/end of his garden as you’ll see from the pictures – his main concern was to ease the visual impact for his neighbours so chose to add sedums to the flat roof. No water added, after a while the pictures show an amazing roof ….the Sedumshack way. We recommended he go to a local plant nursery to recycle plug trays(256 trays) which were cut to fit – they ensure good drainage and will last for decades when dark.
