It took some time, but the flashing on the back veranda is done. No longer (hopefully) will the rain be able to drop between the veranda roof and house wall because it's now covered with some u-beaut flashing bent up by Steeline in Pambula. The flashing comes up the wall about a foot to give a visual effect reminiscent of the lead flashing on 19C shearers' cottages. As in the 1800's there's a practical aspect to this as the coverage will protect the wall from splash back from the roof above it.
The aim is to avoid gutters and downpipes on the main roof (because it would be a pain to clean them). But for this to work we need to protect the walls below, hence the flashing - which I'm sure was the very reason they have such wide flashing on old houses as well.
As today's building code doesn't permit lead flashing on roofs that harvest drinking water (which is just a fancy way of saying that the water runs into a tank) we opted for the modern alternative - folded zincalume.
