Overview
Don't Wait
Leadwork failures are the single most common source of mystery leaks. Water tracks horizontally before showing up internally, often metres from the actual fault.
Our Process
Identify all lead details — chimneys, valleys, abutments, parapets — and assess condition.
Itemised quote stating lead code, fixings and pointing materials, and exactly what's being renewed.
Old lead and mortar carefully removed, chase lines raked out clean, brickwork inspected.
New Code 4 or Code 5 lead cut to correct length, dressed in place and wedged into chase lines.
Chase lines re-pointed, lead surface treated with patination oil to prevent staining of brickwork below.
Why It Pays
Properly installed milled lead lasts longer than the rest of your roof — fit it once, forget it.
Most 'mystery' chimney leaks are leadwork failures. Fixing them properly ends the cycle.
Quality lead develops a soft grey patina that suits both period and modern properties.
All lead we strip out is recycled — no landfill, often a small credit on the job.
Lead is the conservation officer's preferred material on heritage and listed properties.
Our leadwork is backed by a written workmanship guarantee — and lasts long enough that you'll rarely need it.
Deeper Detail
Everything below is what we'd want to know if it were our roof.
Lead is used wherever water has to be guided around an obstacle or junction.
Lead is graded by thickness — Code 3 (thinnest), Code 4, Code 5, Code 6 and so on. For most domestic flashings we use Code 4. For valleys, parapets and exposed details we step up to Code 5 or 6 because they handle weather and foot traffic far better. Cheaper jobs often use Code 3 even where they shouldn't — a false economy that fails early.
Good leadwork follows established guidance: limit individual piece lengths to control thermal movement, lap pieces correctly, fix into chase lines properly with lead wedges, point with a flexible mortar mix, and apply patination oil on completion to prevent staining of the brickwork below. We follow LSA guidance on every job.
On older properties, listed buildings and conservation areas in Durham and Bishop Auckland, lead is often specified by planning. We're comfortable working to those requirements and can liaise with conservation officers where needed.
