Lead sheet is a proven, long-life building material. It is extremely malleable and can be readily dressed to fit the multi-curved contours of many modern building materials and particularly roofing tiles. To ensure this longevity it is essential to follow a few basic rules:

  • Individual pieces of lead sheet must not exceed recommended lengths of 1.5 metres
  • Fixings should hold the lead securely in position without restricting movement under varying weather conditions. With our flashing technique, regular expansion joints will overcome the restriction caused by wedging lead along one side.
  • Nails and screws will have a similar life expectancy to that of the lead because we use copper, brass or stainless steel fixings rather than cheaper and less durable galvanised or aluminium alternatives.

A common problem with some methods of lead work is water penetration where the lead flashings turn into joints in brickwork or masonry. The reason for this is that some fixing products do not allow for proper movement of materials due to changes in temperature and moisture. At Byron Spillard Roofing we take extra care to anticipate changes all year round to ensure a long term water tight seal for years to come.
