Thanks Paul and Klaus.

Paul Overdone so I could stay in the shop longer! Our cat is a bit of a photo bomber.

Klaus There is a pvc sheathing that goes on the roof board and the tiles stick out a bit over that, then comes the drain gutter. it’s a little hard to see in the photo. The reason for this is that the colored cement roof tiles would leave red streaks on the sheathing if the tiles didn’t stick out a bit. It rains a lot here and there is a a kind of colored silt from the tiles. This settles into the drain gutter and is almost like cement.
