Bedroom green roof install

Our bedroom - the smallest and least visible of the two green roofs on the site - is about 3.5 x 4.5 metres in size, and for this green roof we used 9 x 100litre bags of lightweight vermiculite mixed in situ (see pic!) with 8 x 35litre bags of sterilised loam topsoil. This gave us a soil depth of about 15cm.
This mix went on top of a large piece of woven membrane, in turn on top of a kind of black plastic eggbox in sheets which very simply lie on top of our butyl rubber flat roof.
I'm fascinated to see what the birds and wind bring in to this roof so I'll be not seeding it at all and monitoring what comes up - watch this space!
