Is this common practice when doing lead flashing?

[Thatch]

Neighbour has had a new roof fitted, and the roofers have decided to simply grind a sloping groove in my extension wall to fit the lead flashing rather than do stepped flashing.

Is this normal practice?

The roof is a very shallow slope, but I was still expecting a stepped approach.

Doesn't it reduce the water resistance of the brick work?

[Blakeatron]

Quite common to angle cut - but that is terribly done!

Is that "finished" or are they coming back to mortar it in?

[skilly1]

They did that on my house, I filled with appropriate silicon as it looked like a bodge. However mine was neater than that and not so much of a gap.

ETA - they did mortar it in, but most of it fell out when the sun came out.

Seen it all to often. Especially great on semi temporary installations such as a conservatory.....

on the limited view shown that has all the hallmarks of a bodge - any photos showing the flashing/roof abutment length and roof coverings?

[p1stonhead]

Shocking job. But surely not finished? Needs lead mastic for one, but the cut is abysmal.

Also wondering where all the rotten wood is coming from?

[hornmeister]

If that's not finished, driving rain onto that wall will be forced into the groove. At best with freezing weather it'll crack apart the mortar at worst it'll let damp in.

I'd have a word with the neighbour outlining your concerns. Depending on how receptive they are will decide how to take it next.

[Grandad Gaz]

How wide is that lead? It looks huge!

Yes it is common practice. It's the lesser of the three types, cheap n fast.
It's situation dependant.

Thanks all for your responses.

In answer to some specific questions:
- it's not finished, they are coming back, but are waiting for me to replace my rotten fascia before they finish their work (not sure why it is dependent).
- they never contacted me to come to 'agreement' or for permission to grind the brickwork.

Some more photos to but the work into perspective:
Context - my flat roof, next doors tiled extension, joint thatched roof:


Rotten (possibly wood worm) fascia that i need to replace:


They are also suggesting that I need to get some sort of lip fitted to the edge of my roof, otherwise water will flow onto my neighbours roof and cause it to fail again!

Would 'stepped' method to attach the flashing, have been better for me? i.e. is there a chance that this will cause damp to enter my wall?

Jesus christ.

All laughing aside, i assume they are planning on coming back but they didnt exactly 'try' did they.

New roof on an existing extension?

You really need to get your heads together with the guys doing the work on your neighbours house .
You should strip off your drip edge and rotten fascia , they should fix their lead flashing to your wall , stepped would be neater , where they can then put your fascia over the remaining lead flashing and then replace your drip edge , preferably with a small upstand on your side to check the drainage on your side and divert it to the front of your flat roof .
I'm assuming they will be dressing the lead into the profile of the tiles .
I'll be honest , the standard of workmanship on the tiled side is poor . You'd be better off speaking to your neighbour and chasing them and get someone decent to finish the job and split the cost accordingly, I know you'll probably disagree with paying anything but it's the only way you'll get a decent finished job .

[Lotobear]

Given the shallow pitch, and resultant small upstand, by far the better way would have been to lead hang the stone triangle/upstand for the full length of the roof and introduce a series of 1.5mm length soakers, bossed over the pantiles and tucked under the lead hanging.

PS: his pantile roof looks too shallow, even for interlocking tiles

[Ashtray83]

Bloody hell thats a lash up
Should have soakers under the tiles that dress up the wall followed by a cover flashing cut into the wall dressed down over the soakers
like so

[paulwirral]

Only flat tiles or slates use the soaker and cover flashing , thats why I said about dressing the lead into the profile of the tile . The lead should be dressed tight to the tile over at least one profile .

[Lotobear]

Ditto

[Little Lofty]

Poor job, and I agree the pitch looks too low for those tiles.
