Flashing

[Triassic]

I’m thinking about flashing for use around my timber frame.

 

 I have a number of junctions between materials, things like a junction between some stone facing and a rendered section above, a junction between a rendered gable end and a slate roof and a junction between render and timber cladding. Is there any web sites that give details of how such flashings work and what materials are needed, as I need to get such things ordered.

I think advice on flashing might well be  specific to the produce being 'flashed' as it were. The best I can do for you is to point to this site and suggest you follow some of the links.

This was the sort of detail I had in mind, but specifically for flashing....

I suppose the other thing I was wondering about, do you use lead for everything or are there modern alternatives?

You can get pretty much anything made up out of plastic coated alloy, CladCo would be a first website that comes to mind. @pocster was using some flashings recently. Lead is supper expensive these days..... yes you can make use of it in really tricky spots but the modern equivalents are cheaper and look much more crisp.

I don't think you can beat lead for longevity, solidity etc. There's various alternatives some based on EPDM with a layer of aluminium I think. Bet the life expectancy is nowhere near that of lead. 

 

Of course lead has that "nickable" factor.

 

Can't think of anything nicer that lead flashing with seam welded joints. Met a roofer years back on a Laings site. He was that good it was unreal. Known as "Ted The Lead". A dying art sadly...probably due to lead poisoning!

Yep - leads no good for me because I have to angle grind a slot . Will look nice and ‘sharp’ though . Photos when done .

One of my roofer’s wanted to buy a 3m roll of 900mm code 4 just to finish an apex that was 200mm short in one corner...

 

10 minutes and one blowtorch later with my dads old lead soldering iron I’d put the corner on and you can’t see the join ... it’s not difficult to do, you just need to take your time - which is why most won’t do it as it gets put in the too hard box ...

I will check on the spec of the stuff my roofer is about to use.  There's all sorts of stuff going up there, but I'm pretty sure that none of it is lead.  Will get back with details tomorrow.

I worked for a very large chemical company and we has a guy who specialised in manufacturing lead lined pipework, vessels and troughs, his lead work and welding was an art form  in itself.

Found the British Lead flashing fitting guide and thought it might be of interest to some here.

@Triassic did you happen to find the solution to flashing the various areas where different finishes meet? I was pondering the same thing the other day as I have similar joins to sort out to those you describe above!

I’m thinking about using a lead replacement product.

This is one of the few places where you can have a thread titled 'flashing' and no one thinks it's dodgy

Rgr.  I'm a ways from having to tackle the issue yet but I will be interested to hear how you get on.

The Lacomet stuff? I think someone here has used it. Lead, installed correctly, is fairly inexpensive and very long lasting.

Yes we used Lacomet for the dormer apron and frame. Good for flat surfaces but not malleable will only bend in one plane. It's two thin layers of aluminium sandwiching a layer of non-metallic mesh.
