Hi All,

I need to make up a fairly complex shaped lead flashing to go around a
pipe tomorrow. I fancy having a go at soldering the seams. I saw a
programme on TV a couple of years ago when this was being done using a
narrow strip of lead offcut as the solder but can't remember if any flux
was used.

Is it necessary and if so what should I use? I have some Baker's Fluid
and ordinary core solder as used in electronic work.

Thanks In advance

Bob


Bob,

If you want I can scan and email you a copy of the guidance sheet for lead
welding.

Yes Please Bill! Thanks for your kind offer

My application is not strictly flashing. I am replaceing shiplap cladding on
my house by vertical clay tiling. The overflows from the two tanks in my loft
used to simply protrude through drilled holes in the shiplap. I want to avoid
drilling the tiles and so I want to weld an open fronted lead box through
which the pipes enter from the back and will protrude as far as the back of
the tiles. The box will fit in between the tiling battens, and sealed to the
pipes with silicone. I'll be putting in lead soakers behind the tiles in the
regioon of the box. In the event of an overflow, the water will enter the box,
run down over the soakers and appear as a wet patch indicating a problem. So
normally the box will be dry and behind the tiles protected from the weather
but I'd like to think of it properly welded ready for the day when it is
needed. Below the tiling I have flat roof extension with giuttering to take
away the water.

I'm quite sure my scheme is not the approved way but I think it meets the
spirit of the regs as it indicates the problem and will keep the house dry and
will look a lot nicer than pipes sticking out.
