Even though I'm not a plumber I'd still try and use use lead, at
least for ordinary flashing or around a chimney. I might have a go at
trying to join bits with heat or forming a large sheet into a 3D
shape, just to see if I could do it.

Flashband is horrible mucky stuff to work with for your tools and
you.

Only you can answer that. Are you still going to be there in 15 years
time and still be able to clamber about the roof or WHY. I think well
applied flashband will last longer than 15 years, but not the 150
years of a good bit of lead. Code 5 Lead normally outlasts the rest
of the roof...

Don't be a cheapskate on a new build - lead does not cost *that* much.

I've used flashband to repair a crack on the corner of a small leaded
flat bay - I was going to solder it but realised the lead was sitting on
some sort of flammable underlay sheet.

In short, it's good stuff if you don't have a lot of other options. If
you do have options, always choose the best one for weatherproofing.

Your answer is in your question. Or is this a new build with built in
redundancy?

I've used flashband for short-term repair of splits in a typical
roofing-felt-and-gravel type flat roof, but we get a lot of salt in
the air because of our proximity to the sea and the aluminium(?) foil
part corrodes after a few years. I certainly wouldn't use it on
anything structural or intended to be in any way long-term or
permanent.

good man ....

You mean they have not banned lead yet? grin.
I feel sure all the clever folk could come up with something other than
lead for this sort of task though. Its been traditionally lead for hundreds
of years now.

I've done a fair bit of lead work here - and as well as being great fun
isn't too difficult to learn as it's a very forgiving material. If only it
wasn't so expensive.

Generally, all joints tend to have to be lapped types to allow for
expansion, when used outside. Something like every metre.

Most lead has been replaced with various sorts of plastic these days.
You can buy plastic valley pieces and aluminium soakers for roof work.

Solves the thievery problem too if you have pikeys in your area.

Flashband has limited uses, eg it has to be continuously supported, only
bridges very narrow gaps.
Ocassionally there are problems getting it to stick, even with primer.
(Best applied in hot weather).

Love to know what plastic has anything like the life of lead when exposed
to the elements.

Lead lasts for many decades. Even centuries.
However there is a move to get lead out of the environment.
Causes brain damage.
Could be TNPs problem.
Usually cracks appear in it on corners etc due to work hardening and
vibration with wind. Eventually.


Noboby knows how long the plastic stuff will last.
It is tested by the BRE.

Yes - a couple of hundred years and it might need work done. Most plastics
go brittle in a couple of years of sun.

not quite...seen a lot of eroded lead on 100 year old Scottish
tenements....but they have been poking up into polluted skies for
years....and 50 year old water pipes but that is a different story.....

The cracks are mainly due to thermal cycling.
Hence, larger pieces have shorter lives.
You should get at least 70 years from a good installation
using lead strips. (Sheet lead may be less - not sure).
You may need to redress it into brickwork one or two times
during this period if the mortar and/or wedges fail, which
again does happen due to thermal cycling and movement of
the lead.

Noboby knows how long the plastic stuff will last.

I've had a GRP valley gutter for almost 30 years. 10 years
ago, I refitted the roof around it, but the plastic itself
was fine and I kept it (just had to add new sand strips for
pointing onto it).

About 8 yrsago we had lead capping on a wall (recently built as an
extension to our church.

Negotiatin with the insurers had them insisting that the lead was
replaced like-for-likerather thab a cheaper aliminium /zinc/felt
replacement. Why when it was probably cheaper and certainly less
attractive?

Nuralite flashing also seems to last quite well....
