Hello folks. I am in the process of completing a self build house project and have discovered a problem with the lead flashing trays which were built into the chimney.
The builder did not coat the trays with patination (think that is how it is spelt) oil and after having completed the roof it is now leaking down the tiles and staining them. All exposed lead is coated but the leakage is coming out from between the chimney blockwork.
Any ideas for removing lead stains from tiles or suggestions on how to remedy this eyesore? :cry:
