Lead Flashing question

[jacksonscraft]

Evening All, I want to install some 6" lead flashing around these upstand walls which are approx 700mm high, to go over the felt going up the walls. .

As you see here there are coping stones and they're in ok nick. Do you think I can tuck the lead in underneath the copingstones or should I grind out a line half way up the wall and install it there - lower?

many thanks for reading....

Where on the 700mm high walls did you plan on fitting the 150mm flashing?

 

[jacksonscraft]

I was thinking of putting it directly beneath the copings. Tucked in under them.

How do you propose to get the lead flashing in under the coping stones.

 

[jacksonscraft]

I was going to grind out a line. I can get my angle grinder underneath. So can it go there or lower?

I was thinking of putting it directly beneath the copings. Tucked in under them.

I can't see any point at all in fitting flashing at that point, or anywhere in fact on that parapet.

You've got a 700mm upstand; just how high up that does the felt go, and how well is it sealed to the wall

If you have a convenient mortar line just above the felt, then rake that out, and use that instead. If not, cut a line somewhere convenient,

thanks all. There's felt strips going up the upstand walls to beneath the copes. Some of the felt has collapsed and come away completely..On a higher section of the wall which is about 1m high, the felt doesn't go all the way to the copes and is exposed to the weather. There are holes in it.

I did a repair on the roof which the insurance wouldn't pay for cos they said there was no lead cover flashings anywhere. So I thought install some all the way along and tuck it under the copes? But not sure if that's a good idea.

Then you might be better of cutting down the felt to about 100mm from the roof, and then installing the lead flashing.

Your insurers were wrong, as you don't need lead cover flashing.

With that felt upstand so high up the wall, it is sheltered by the copings, so as long as the felt is sealed sufficiently, then it's fine.

If you want to install lead, then don't disturb the copings. Cut a joint one or two courses below, or lower.

Roofing felt does not like the sun, some component of it rots away and the tarry bit goes rock hard. I would go along with Woody and remove as much of it as possible because it will fail at some time. 6" is only just enough to flash from the base upwards.

Ok Ill do that then and I won't disturb the copes. About 6" up from the roof surface the lead shall go. Many thanks for your help fellers ...
