Weather-proofing a projecting brick course

[Davey Boy]

Hi all - as I am about to embark on a roofing project, my research brought me to this website which I have found informative and hilarious in equal measure. Hence I thought I would reach out to get the guidance of roofers and leadworkers alike for my following dichotomy. Below the parapet of our house is a projecting brick course, which when we arrived was covered in moss, damp, and darkened with weathering. I am considering running some lead flashing over it to ensure there is no ingress, but have a few questions that i would welcome your thoughts on:

1. What code lead would you use?
2. Should the flashing start 2 courses above the projecting brick course?
3. I assume the lead should be run in 1.5m strips max?
4. Where the lead laps should it be folded back/sealed in some way?
5. How should the lead be held down to avoid it lifting/flapping around in the wind? Leadmate, or fix a batten below the brick course and use lead dots? Is there a risk fixing with dots that you risk the lead tearing over time?

Ive attached a few picks and profile drawing of what i am considering. Thanks in advance for your time and attention - d.

Looks like there's a flashing or something beneath each over-sailing course already?

"over-sailing course" - never heard it described as that - love the technicals! So the grey lines you can see beneath each over-sailing course, looks like it is just cement pointing. It is a very neat straight line however - do you think there could be lead behind the pointing, and under the course?

Looks like a pointed joint cut off to me.
The sand and cement pointing won't be doing it any favours ...

And the million rouble question is ...... why?

 

[datarebal]

I don't take roubles. There isn't enough in the world worthy of my knowledge .
Euro or us dollars please

It would seem a shame to cover up a traditional brickwork detail like that

Not that I know anything , but given the pic (...and bend in the lead?), I would agree with the above!

It's just struck pointing. The pointing had dipped where the the fella trowelling has followed the hollow spalled brick. The joint a couple of courses down is pointed and struck the same.

Thanks, I did question myself after posting.
I couldn't see any joints!

And the one million rouble question at today's exchange rate is ..... lead or mortar?

 

[datarebal]

Not lead

Not lead

Where do you want this? Enjoy your sandwich.

Kyiv if it's not to much trouble .
Just mind the c rams.
Or maybe Berlin , they need to feed the gas meter

Folks - firstly, sorry for the delay! COVID finally got us... virus in itself was fine, but having all the kids off school while trying to work was painful! The comments however have made me chortle, and feel much better. Now to your questions:

And the million rouble question is ...... why?

Sounds ridiculous as i type, but the course looks dark, and will definitely be a point of ingress, and what with the plonker who repointed the place with cement (not lime mortar), any moisture will no doubt linger... And I thought a nice bit of traditional lead would look quite neat...

Not lead

Fraid to confirm you are right - there is a broken section of struck pointing, and ive checked i cant back to the lime, theres no lead hiding

Re picture - haha, at some point it will be cheaper to burn fivers than use the gas!
