I have recently bought a house which has had a lean-to extension built to the side of it. I found out shortly after moving in that there is a hideous leak in the leanto roof and when i looked at the flashing (which was mentioned breifly in the survey) it looks like a botch job. its basically a lead strip sat on top of the roof and going up the wall, rather than going into it. Obviously this means that water will run behind it straight into the roof.
I want to replace the flashing but will need to cut into the wall to do it, i'm not sure on how deep to go or what to cut with (i thought an angle grinder?) I dont know what soakers are either and whether or not i'll need them, and finally, do i need to secure the flashing or will the mortar for re-pointing the groove i cut hold the flashing in place?
Any help would be greatly appreciated as i am quite a novice.
