I have a three bed 1930's semi. It has a bay window on the ground floor and the roof extends across the enire front of the house and joins up with next door. The top half of the house above this roof is pebble dash which comes down over the roof tiles. There is no flashing. About 6 tiles on the top row have slipped down and made a large crack in the pebble dash (in actual fact there seems to be a dodgy repair here with cement). In short there is a wide crack in the pebble dash where the roof joins the wall. Can anyone suggest some remedies for this problem. I don't want to spend big but I don't want to do a bodge job either.
Thanks
