The sedum roof will need annual “maintenance” to check that all plants are healthy and to remove any weed growth that might compete with the sedum. So to comply with the safe working at hieght directives we have fitted a guide to limit the movement of a safety line when people walk on the roof to do this work. This top rail can be fitted now the sedum in place. The sedum should grow to a height of 75-100mm so this will eventually be more concealed.
