Flat roof flashing

AdrianW2

Our extension flat roof is felt covered and the join with the main house wall was done by continuing the felt up the wall. This has now come away, forming a funnel that channels water into the wall.

I'm hoping to fix this but I'm a little confused by the range of tapes, rubber solutions, paints and primers on offer. The only thing I don't seem to be able to find is a roll of lead sheet.

Any suggests for a cheap fix?

I cut about 1 inch into the wall of the house using a grinder, then inserted 1.2m long strips of lead horizontally with a 20cm overlap between sections. The lead was secured to the wall using lead wedges hammered into the slot above the sheet every 12" or so.
I think it is code 4 lead you need, but check with who you buy it from.
Best to get it from a roofing supplier.
You will need patination oil aswell to stop the lead from oxidising and a lead dressing tool.
Nice job to do in the sun with the radio on.
The lead will cost about £50 and the oil about £10. I think the lead only comes in 5m rolls so i had to buy 2.
