Hi,
For the past few months I've noticed a leak in the roof causing water to drip down the outside of the chimney on one side of the loft. I had someone come to fix it and he replaced the lead flashing at the back of the chimney. It didn't work however and the water continued to leak through as before. He came again today and said that he attached the felt under the tiles to the chimney and put sand cement over the flashing at the top. Looking at chimneys of nearby houses I don't see any that have sand cement covering the lead flashing. Is this OK?
