A natural green roof

    Hmm, good point, wildedges. I know they would need handling with great care, but whilst these are abandoned panels, I don’t think they have ever been used (no fixing holes). I wonder if  they could be affixed with some sort of clamp to a framework, perhaps with a bit of padding, or glued somehow? Wearing a hazmat suit!

    wear a proper face mask (not a little paper doobrey) and do whatever you're doing outside not in a shed. If you make the roof very nearly flat, you don't need much in the way of fixings - a large overlap and a wooden frame (fixed to itself rather than the panels) over the top to stop the panels lifting if the wind gets under, iykwim.


    Are you sure it's asbestos and not just fibre cement?

    Thanks @raisingirl, I am pretty certain they are asbestos, had to deal with it in the past. My neighbour has acres of the stuff on a wide variety of outbuildings, but being good Dutch people, they are going to get it all professionally removed and replaced with something more environmentally friendly. I do wonder if it will just end up in land fill somewhere though, despite what these companies say...

    I am sure I could devise some framework to keep the panels intact, just doodling in my head at the moment, a winter project maybe, along with the fruit cage and the reorganisation of my composting area. The latter is looking like a good contender for the Garden of Shame thread just now!

    I found another sedum trying to start its own unoffical green roof today. Sadly not a good sign on a modern slate roof and indicates the owner may have some repair work to pay for fairly soon. :#

    We walked past this lovely, stone-tiled cottage yesterday and I noticed the porch had quite a few sedums and sempervivums growing on there. I only managed a quick pic as I was being dragged along at the time. I don't think the ivy is such a good idea though.

    Another wild green roof sighting. This time on a tin roofed lean-to attached to an abandoned chapel. The roof slope faces south-west with no shelter so the plants must get absolutely baked on there at times. Sedum acre in full flower on the tin and some nice ferns growing out of the top of the old stone wall below.

    Nice to see Wild Edges' style "sedum on the roof" in this week's GW

    I actually watched it this week and quite enjoyed it. If you haven't watched Beechgrove, Chris Beardshaw has opted for a different name for a green roof  ;)

    I've just finished another one for my 2nd bird feeder cage. They're easy to do in a smaller way if you don't have big areas, or sheds etc, to put them on. 
    It's a place where beautiful isn't enough of a word....



    I live in west central Scotland - not where that photo is...
  • The first time I saw a green roof was at a visit to the Centre for Alternative Technology in Wales.
    This was about 30 years ago and I was very impressed.

    I see a lot of intentionally planted green rooves that seem pretty dead and untended. We have some on the road and I saw one yesterday, on a large scale, on a school roof - brown and desiccated. People seem to think they need no care at all, which is a mistake. I suspect they have been somewhat oversold as an easy, hands-free alternative to gardening.

    We have a damp, neglected alley close by where harts tongue fern has self-seeded into the wall cracks - Lord knows from where. It's always a pleasure to pass and see a happy, self-inspired green, "living wall". I'm not sure I could try to make that happen if I tried. It's like a lush mini-miracle worthy of Chelsea.
