Full breakdown in the roof repair cost guide.
Lead expands and contracts with temperature. Pieces over 1.5m split at the folds. Most failures are either thermal movement or poor original fixing.
Sometimes a failed section can be sealed as a temporary repair. For a permanent fix the lead comes out and new is fitted.
Ubbink and Wakaflex last well and are a sensible choice where lead theft is a local risk, which it is on some Walsall streets.
A soaker is a small piece of lead that slips under each tile at the junction between the roof slope and a wall. Step flashing sits over them.
