Hi All, at my parents house they have a small parapet wall between a flat garage roof and pitched extension roof. They have a water leak in the ceiling under the pitched section. Looking above this area the copings the builder has fitted are the same width as the wall so I'm thinking with no drip edge that this is the cause of the leak. The verge and tiles all look OK to me. I was thinking of dressing the whole thing in lead but have never done that before and would appreciate advice on this.
Parapet Wall Copings wrong size

Dressing in lead would make more sense, as that is an odd sized wall (width).

Today had a second look at the roof and lifted up the lead flashing. The first 7 tiles in the row under the flashing are slightly shorter than the rest as that bit of wall is slightly forward of the main house wall. So the roofer has cut the top edge of these tiles off. To mechanically fix these tiles as they have no nibs to sit behind the battens the roofer has used an angle grinder to cut a slot in the tile which is almost the width of the tile just for 1 nail to be fitted. Each nail is sitting about 5mm proud of the tile pressing into the lead. I suspect water has got behind the flashing and dropped down these large cut slots. The slots are about 2/3 the way up the lead. This looks poor to me how they have done this. Just thought I would let you all know what I found.
