Morning Guys,

Hope everyone is well.

Any lead-workers about by any chance?

I have a leak (small drip) that is coming through the top bedroom bay window. After removing the cladding (from the inside) I could see a few holes in the existing flashing, indicating replacement.

The work area measures in at 3.5m x 600mm.

There is only 1 supplier that I have found who is prepared to get me custom cut of lead but the price is extortionate. The cheapest price I have found for Code 5 (6m x 600mm) is £229.25, which still, is on the high side for me.

I have a few questions:

1. Is there a cheaper and/or better alternative to Lead? If so, how reliable is it?

I have read some online articles by the Lead Association and Calderlead that state you should lay lead in lengths of 1.5m strips.

The total width I am covering is 3.2 - 3.5m.

2. Do I cut two 1.5m strips and one 0.5m strip? or is there a better way to divide/cut the lead to cover the working area? i.e. three 1.16m strips?

3. Whichever option is best in question 2, what method is the best to join the overlapping strips? - nails, screws, lead sealant or just simply hammering it down?

4. When overlapping each strip, by how far do I overlap each strip for e.g. does strip 2 need to overlap strip 1 by 100mm?

I am a complete newb and I would be extremely grateful for your help and advice.

Thank you very very much for helping

Aye, put forward a suggestion then thought better of it.

Hahaha no worries bro.

If its best to go with Code 5, I will but I really could do with some help regarding the technical questions.

Cheers mate.

Thanks for the links mate.

I read both of them but I couldn't find the info I needed with regards to questions 2, 3 and 4.

Perhaps you saw something I missed in those articles?

Thank you again.

Leadwork (i.e. lead rolls, burning, bossing etc) is a highly skilled craft and not a diy undertaking.

The odd flashing and apron maybe, but not a complete roof.

All the answers lie within the links, as knowitall says anyway really.

I think you are confusing lapping flashing (which is vertical) with joining lead on an almost horizontal roof

You can't just overlap lead in this use on a bay roof - water will get between the lap. Normally a rolled joint would be used, or perhaps a soldered joint

You may be better off getting a mod to move this thread to the roofing section, as there is a guy (Leadman, I think) who should be able to answer this in more detail

There is also the dressing around the roof perimeter to consider

That's what I was thinking originally - water getting between the laps.

Forgive me for my ignorance but what is a rolled/soldered joint? The first thing I am thinking of when reading "solder", is multiple pieces of lead being soldered at the point they join.

Would you also be able to confirm the 1.5m rule? - Does the lead for this particular case need to be cut at 1.5m lengths?

Thank you friend.

1 no not really imo

2 split it into equal sections ,eg 3x bays so you would need to wood core rolls.

3 If its flat or only has a small fall you are looking a wood roll , standing seam is possible but harder to achieve.
The only way to do it with out is by welding in a rubber expansion strip or two if diemensons require ,haven't used it in years but used to be pretty expensive

4 overlap is based on the pitch of the roof and its nota option if its flat

I'm a city & guilds qualified lead roofer, LAS reg'd etc, here is my advice to you;

Get a bloody lead worker to do it, its all well and good having a go at general DIY, but were talking a lot of money on materials here, materials that need to be used to the proper standards, or they are rendered useless.

Average cost to renew a bay roof in lead = £550-£750, if thats unaffordable I suggest you consider cheaper alternatives.

Trust me, if you dont know the basics ie lappage, length codes etc, this is not a job for you to undertake!

 

[systematic]

£550 - 750

How much is that paid towards labor?

How is it relevant.
