Lead Flashing Roofers in Nelson

Code 4 and code 5 milled lead — the only material we use around chimneys, abutments and valleys.

Why Lead Flashing matters in Nelson

Hand-dressed milled lead sheet to BS EN 12588. We use code 4 for soakers and aprons, code 5 for chimney stacks and exposed valleys. Dressed and chase-fixed properly, lead outlasts the roof covering itself.

Nelson specifics: Standard on Burnley/Padiham stone-built terraces; the wrong gauge cracks in two winters.
