A sign of dump started recently show on the chimney breast as it enters the first floor bedroom, I install though the flushing leadwork needing sealing. My roofer went up to have a close look and he said that leadwork is in very good condition and he could not spot any gap or leak. I went into the loft and to my surprise the chimney stack is dry. My roofer does not know exactly what is causing dampness and he suggested that repointing the chimney stake may solve the problem.
Any idea please
