The principle difference between SA rooves and ours is the lack of "felt" (nowadays replaced by a waterproof and breathable membrane). This is a strong second line of defence against wind-blown water-penetration.
The rest is pretty orthodox, and quite comparable with modern estate-type houses in the UK, although we would never build with such shallow roof pitches, or with such widely-spaced rafters. Also, you never see water-proof jollop applied to the outside of a roof over here like in your 2nd and 3rd last photos.
Something that UK members might not know is that parts of South Africa (the "high veld"......Johannesburg and surrounds) have thunderstorms which are so severe that hail will write off any car that is left outside. Consider the type of roof you would have to construct to cope with that!
Anyway, nice to see the photos. Thanks for that, Erich.

(But my experience with tile roofs is limited to helping carry tiles onto the roof of a house my dad built back in the early 70's. My sisters and I had to carry a quota up every day, three tiles per trip (7 lbs apiece) up a 2x12 to the nearest corner of the roof, and then over to wherever my dad was working. )
As for the flashing, I've never seen or heard of anything other than aluminum or galvanized steel here in the US, except on historical buildings where copper (or, I suppose, lead) might be used.

Mike G wrote:No photos, but I took a day out from my house build today to re-felt the workshop. It has stood too long with the old membrane exposed, and it leaked like a sieve during that storm last night. There was an inch of water on the floor this morning..........so everything out to dry, and then I popped the scaffold up, pulled the battens off, and put a new membrane on. I'll get the slates on in the next few weeks.
