A quite desirable property, thanks to all who replied. I seem to be able
to get lead from sheds in 3m lengths, where my longest run will be
double that, anywhere sell longer? (then I might need a forklift to get
it up to the roof though)

If I stick with the 3m lengths, is an straight overlapped joint ok, or
better to aim for a wrap around like so?


Best is soldered, to me: However, when my lads were laying flashing,
THEY said that more than 1.5 meters should not be laid as a length as
expansion/contraction would rip it apart..since it was a sloping valley,
they simply overlapped it. I like the solution you have below though -
for a flat roof it should be good.
