Saturated, the system weighs 85–100kg per m² — a real structural load that a shed or garden room roof may not have been designed for. Have the structure checked by a competent person before ordering; on new builds, design the deck for the green roof from the outset.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat goes underneath it?\u003c\/strong\u003e Sound, continuous waterproofing. A sedum system is not a waterproofing layer — it sits on top of one. An EPDM rubber membrane is a common and durable choice beneath a green roof, and the sedum actually extends the membrane's life by shielding it from UV.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow is it laid?\u003c\/strong\u003e Fleece down first, then the drainage\/water reservoir layer with the white fleece facing up, then rake out 2–3cm of the growing medium, then roll the sedum blanket out over the top and water it in.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it need edging?\u003c\/strong\u003e Yes — the system needs restraint at the perimeter to hold the build-up in place and leave a clear drainage margin. Aluminium edge trim is the usual solution and is ordered separately to suit your roof's perimeter length.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow much maintenance?\u003c\/strong\u003e Low, not none. Expect to water it through establishment and in prolonged dry spells, feed it roughly annually, and keep outlets and drainage margins clear of debris.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat pitch does it suit?\u003c\/strong\u003e Flat and very low-pitch roofs.
