Fitting subsitute lead flashing to a brick wall

[Jacka]

Hi all

I have a flat roof on my house (just purchased) which covers the kitchen sink. It has been done with felt with is cemented into the bricks which looks an absolute mess. To cover this I have managed to acquire some substitute flashing which I will have a go at installing in the next couple of weeks.

What I would like to know is once I have removed the pointing from where to insert the lead:

How far do I need to insert it into the brick

How do I finish the pointing?

Cheers

Jacka

Cut the joint out about 30mm, make up a few lead wedges and fire them in.
You can repoint with sand/cement and finish with a bucket handle joint.
Another option is to use Lead mate, comes in tubes to fit skeleton gun.

If the 'substitute' is Ubiflex, sealer will need to be Butyl based, normal silicone LM bleeds the bitumen content out. Sand and cement would be fine also.

I've seen tapping bits of lead into lead flashing to keep it in place, but can you do that with substitute

Is lead mate butyl based?

Lead mate will bleed the bitumen out if its Ubiflex. There are a few lead substitutes that will do, Rapidflash is one, many made to look like lead.

Lead wedges will hold any in fine, but they need installing correctly to be effective.

Instead of lead wedges can I use the substitute to make wedges?

I'll check the make tonight when I get to the house!

I use hall's flashing clips now, stainless steel easy to use quicker.
