Lead is used around chimneys, skylights, flat roof edges and valleys — and when it fails, water follows quickly. We carry out all types of lead work on King's Lynn properties, from re-flashing a leaking chimney to full-scale flat roof lead coverings. All our lead work is dressed and finished to BS EN 12588 standards.

Lead is the material of choice wherever a roof meets a vertical surface — around chimney stacks, dormer cheeks, valley gutters and parapet walls. It's durable when installed correctly, but old or poorly dressed lead cracks, lifts and allows water to track into the roof structure, often showing up as damp patches on internal ceilings well away from the actual entry point.
We work with milled lead sheet in the appropriate code weights for each application — Code 4 for flashings, Code 5 or 6 for flat roof coverings. Flashings are cut, dressed and stepped into the mortar joints of brickwork using proper lead wedges and weather-resistant pointing. We don't use flash band or silicone as a substitute — those are temporary fixes that tend to fail within a couple of seasons, particularly in Norfolk's changeable climate. For flat roofs, lead is laid in bays with proper drips and rolls to allow for thermal movement, which is the main reason DIY lead work fails.
Lead work requires an understanding of how different metals behave under temperature changes and how to detail junctions so they shed water rather than collect it. A poorly dressed chimney flashing is one of the most common causes of significant loft and ceiling damage we see in King's Lynn properties.
We survey the affected area before we quote, so you're not paying for guesswork. Most flashing replacements around a single chimney stack take half a day to a full day. We guarantee all our lead work for ten years against defects in workmanship.
Replacing lead flashing around a chimney in King's Lynn typically costs between £300 and £700, depending on the size of the stack and the condition of the surrounding mortar joints.
