Lead flashing around chimneys, dormers, and abutment walls is the most common point of failure on older Norfolk roofs. We cut, dress, and fix new lead to the correct code for the application, stopping leaks at their source rather than masking them with sealant. From small step flashing repairs to full valley replacements, we handle it properly.

Lead work is the junction between your roof covering and any vertical surface - a chimney stack, a dorsal wall, a parapet, or a change in roof pitch. When it fails, water tracks down inside the building and the source can be deceptively difficult to trace. Many of the damp patches we investigate in Poringland properties turn out to be failed lead rather than missing tiles.
Good lead work means selecting the right code of lead for the location - Code 4 for most step and cover flashings, Code 5 for soakers and chimney back gutters, Code 6 for flat areas and wide valleys. We cut lead to length on site, dress it into mortar joints using a chase, and fix it with lead-welded clips so thermal movement does not pull it loose over time. Mastic and silicone applied over old lead may stop a drip for a season but never addresses the underlying problem, and we will not use them as a substitute for proper work.
Lead installed and dressed correctly has a service life of several decades. Getting it wrong - wrong code, poorly dressed bays, mortar raked too shallow - means the same leak returning within a few years. We use traditional tools and follow current LODA guidelines on bay lengths and fixings, which limits stress cracking caused by expansion in summer temperatures.
When you call us about a suspected lead failure, we inspect from scaffold or a properly footed ladder, photograph the problem, and explain exactly what needs doing before any work starts. Most straightforward chimney flashing jobs on a single stack take half a day to a full day.
Lead flashing replacement on a standard chimney stack in the Poringland area typically costs between £350 and £750, depending on the number of faces, the code of lead required, and access difficulty.
