what code of lead to use

[bomberns127]

hello, i am having a kitchen built and was wondering will code 4 lead be ok for the flashing? weather can be a bit fierce here, and how much does need to be safely on the tiles and going up the wall? will approx 9" be ok, 1" in the wall, 3" down the wall and 5" on the tile?
thx in advance

I take it you mean an Apron flashing?
Code 4 is ok.
You ideally need 150mm on to tiles, 75mm to raked out brick joint plus depth of raked joint(25mm min)and no length longer than 1500mm.

So 250mm minimum required.
