Leaking at abutment despite new roof/flashing

[tabir]

Have had a leak at the abutment join with the neighbours for some time now. We are stepped down from them and it appears the issue has existed for quite some time as plenty of bodges to try and fix it have been found. We decided to get a new roof eventually as it was looking tired anyway but the problem still exists and the roofer is saying it’s nothing to do with him now and the bricks on next doors gable end have gone porous. On removal of the original roof we discovered the stepped lead flashing had been covered over with an apron flashing crudely hacked in across the brickwork (clearly a previous attempt to fix this issue). With the new roof we have a grp secret gutter and individual stepped flashings but the water continues to come in at the same points, track down the walls in the loft and eventually leave wet patches on the bedroom ceilings and walls. It only happens when there is both heavy winds and rain. We are at a loss now and don’t really want to waste more money than we already have to achieve nothing. Is porous brickwork a thing even? We are very exposed to the weather where we are. The bricks have also been coated in stormdry cream but this appears to have done nothing. Now being told all we can do is render next doors wall? Any thoughts welcome. Thanks,  https://restonroof.com/silver-spring-md.php

You are in Singapore - this text was copied and pasted from a post in a UK forum 3 years ago.  You could have at least kept the paragraphs.

Dealing with a persistent leak can be frustrating. Porous brickwork is a real issue, especially in exposed areas. Consider rendering the neighbor's wall and thorough inspections to address the problem. Invest wisely to avoid further expenses.
