Leadwork & Flashing in Nelson
Nelson leadwork is mostly Pendle valley re-forms and chimney aprons — and ice loading means we use code 5 with stainless clips at every joint as standard.
Leadwork & Flashing for Nelson properties
Lead is the difference between a roof that lasts 50 years and one that leaks at every junction. We dress lead flashings around chimneys and abutments, form valleys, aprons and step flashings, and re-cover lead bay-window roofs in heritage code 5 lead with rolled joints — exactly the way they were originally built.
About Nelson
Pendle valley town — densely terraced cotton-mill housing with original slate roofs, sat below exposed Pennine moorland.
Housing stock: Long terraces of two-up-two-down millworker housing, plus larger end-of-terrace properties on Manchester Road. Many roofs share continuous valleys and party-wall chimneys.
Local exposure: Sat in the lee of Pendle Hill — strong wind funnelling, heavy rainfall and frequent winter ice loading on north-facing slopes.
Planning context: Pendle Council enforces conservation standards in central Nelson and Barrowford — natural slate and traditional ridge detailing are the default.

Frequently asked
- Why does lead flashing fail faster in Nelson than other towns?
- Pendle freeze-thaw cycling is the brutal local factor — water expands inside any joint that isn't perfect, and lighter-code lead fatigues from the constant cycling. Code 5 with proper clips solves it.
- How long does leadwork & flashing typically take?
- 1–3 days depending on detail — bay roofs typically 2 days, single flashing replacements often a single day.
