A natural green roof

I have a love for green roofs, and today I was at work and saw this beautiful roof on the roof of an old stone barn. Don't pay attention to the asbestos sheets, but the plants look very happy, you can even see a lot of dried flower heads, so the plants must like it there. It looks mostly like sedum reflexum/rupestre with a bit of umbilical cord rupestris and a bit of ivy growing on a thick bed of moss. I'm thinking of throwing in some local compensation for sempervivum there if I ever pass by again.

The roof faces northeast and is shaded by an old sycamore tree most of the day. In the summer, it should be in a good spotty shade and, obviously, has survived this summer heat.

Usually I call special people who clean it for me.

The roof of my country house has gone green or “brown” over the course of a Spring in which I did not visit the country house. When I finally did, I witnessed its beauty and almost felt bad when I had to order roof replacement. It needed to be replaced because it was a pretty old roof, it was there when I bought the house and it was starting to leak and overall break down. It pained my heart but I really had no choice. I do have pictures of the green roof but I would have to look for them. If someone is interested, I might look them up.
