   Hi Gary,

   Spot repair of minor damage to lead flashing is quite common, and the main option for this is indeed to weld new lead over the old. This is skilled work and should not be undertaken on a DIY basis, as it involves hot work near structural timber. So, I would strongly recommend you call out at least two appropriately qualified roofers to assess the flashing and provide a detailed quote for their recommended repair route. Depending on the extent of any damage, it may be more prudent to replace the entire flashing. In either case, ensure it’s clear in the quote whether new lead is to be used.
