I am thinking of a roof with 30cm of soil on top and sedums growing in the soil. No idea of anyone in Tassie does this.

Gutters are a concern—they fill up with leaves and other organic refuse and will burn and bring the fire into the roof space. I am too flipping old (plus other reasons) to get up on ladders!

There was a radically different type of gutter demonstrated on the old “The New Inventors” show—leaves fell over the edge of the roof and fell to the ground while the water ran under the roof and so into the gutter. Very nice solution but I have no idea if this type of gutter is available.
