Split leadwork

A split in a lead detail can look like a straightforward patching job. Before choosing that repair, the useful question for the assessment is what caused the failure and whether the same condition remains.

A homeowner does not need to calculate movement or select joint dimensions. They do need an explanation that connects the observed damage to the work being proposed.

Look beyond the visible opening

Lead expands and contracts as temperatures change, so the dimensions, joints and fixings matter to how the detail performs. Tell WWR Roofing where a split has appeared and whether the same area has been repaired before. The assessment needs to consider the surrounding arrangement as well as the visible opening.

Ask the contractor to identify the affected area and explain whether the problem appears local or relates to the wider arrangement. If opening up is needed, agree how the findings will be recorded.

Define what a repair will achieve

A temporary weathering measure and a permanent replacement detail have different purposes. The quotation should state which is being proposed and any follow-up required. Avoid relying on the same word, “repair”, for both without clarification.

Where a local repair is recommended, request an explanation of why the surrounding material and detail are suitable to retain. Where renewal is recommended, ask for the extent and the reason a smaller intervention would not address the finding.

Preserve the history of repeated work

If the same area has been patched before, provide the dates and any photographs. A repair history helps the contractor understand what has changed and avoids treating each visit as an isolated event.

Keep the final recommendation with the completion record, including any limitations. If the symptom returns, that document gives both parties a clearer basis for follow-up than a vague recollection that the lead was “sealed”.
