Got a leak in my valley (or should that be leek?). And I'm pretty
sure I've found the cause -a small 10 cm horizontal tear across the
final sheet. I think it's the cause because some silicon sealant
roughly squished in on the end of a stick leaning out of my velux
does reduce the drip in the attic. So on the next dry day if I stick
a length of flash banding down the valley will this stick for a few
weeks so that I can plan my next move? Or is there some better
solution that someone could suggest?

Alistair in very rainy Manchester

a lead patch adhered with leadmate will last a /very/ long time.


Really. That would be great, but doesn't it matter that it will be
proud of the existing surface, albeit only a lead thickness? I guess
water will just run around it.

correct. still a temporary fix though, the valley will need replacing.

1/ make a lead patch about 1" bigger all round than the hole.

2/ apply a generous bead of leadmate to the radius of the patch.

3/ apply patch, run wet finger round the leadmate to smooth off

I prefer to use latex gloves when using leadmate as it really does
stick anything to anything.
