EJ Roofing carries out all lead work.
The lead flashing usually sits around the base of the chimney and along areas where a roof will meet other materials.
Sometimes the lead flashing is not fixed well, and can be refixed, other times storm damage or general wear and tear will create the need for new lead flashing.
The obvious signs of defective lead flashing is damp at ceiling/wall level just below the joint, or damp in the loft space.
