That's not good work, I suspect that he's not a roofer!

Works should follow Lead Sheet Association guidance Calder-GTGLW-210213.pdf (calderlead.co.uk)

And look something like this
 

I read the "stepped" comment and was inclinde to agree, but this is beautiful

The idea of a plumber doing lead flashing work on a roof is a new one to me.  Flashing work is part of a roofers trade.  When we had an extension done the roofer did all the leadwork, including creating a lead lined gutter.

Leadwork is part of the plumbing apprenticeship. The name plumber comes from the Latin for lead.

But... Now that lead is no longer used for pipework, and there is a push towards plastic pipe & push fittings, I suspect many plumbers don't get trained in the art of leadwork.

Must admit, I'd go to a roofer for flashing rather than a plumber (or do it myself).

In the cable industry if working on lead sheath cables the jointer and mate used to be supplied a pint of milk each per day to counteract the possibility of lead poisoning. Kind of fell out of favour from the seventies onwards.

It's still part of a plumbing apprenticeship. A lot of modern plumbers haven't done one though. Some of them have gone into specializing in lead work.
Basic flashing and soakers are pretty simple.

Thanks for all the replies and info. Interesting stuff there.

I did have a word about the sealant but he said that is the proper sealant for the lead. He said after I while I won’t notice it it will blend in but if I’m not happy and I  want it taken out and grey put in he will do it. But after all the comments and looking at pics and other houses with similar flashing I’m not sure he’s skilled enough in leadwork. I’ve never seen any flashing look like that before or be that wide, but if there’s anyone who has, or thinks I’m being picky let me know! 

I’ll send a pic of it ‘finished’ tomorrow.

Ask him what code (thickness) lead he used.

For flashing Code 4 (1.8mm thick) is recommended. Code 3 (1.32mm) is a bit too thin.

Thanks @FreeBear, will do. I’m pretty sure he said he was going to reuse the old lead that was there originally but then said that it was going to be too thin at only code 3 so I’m guessing that would be code 4.

Lead flashings is a plumbers job, a good apprenticeship is required. You won’t find any roofers doing lead work on new builds. A lot of so called plumbers nowadays are not even trained.
Ask them to make a chimney back, and do lead burning they’ll run mile.

Anyway that job is a mess, it should be stepped flashings ( cockney). Code 4 lead. And treated with Patination oil. Nowadays we use stainless steel wedges and grey lead sealant so it blends in with the lead Calder is a good brand. Plus the lead shouldn’t be longer than 1.5 mtr or it will split over time.

It’s a lazy/ cowboy way just to grind a slot along the brickwork, instead of racking out the joints.
Conservatory fitters do it all the time ( shameful) what happens if you decide to do away with the conservatory in a few years. You’ll have  change multiple bricks because of a bl**dy deep cut along the brickwork, done properly you’ll only have to repoint the mortar joints.

Those are just basic lead soakers, as long as there’s a  under/over lap then all ok. And code 3 can be used. But looks like no patination oil used.
