Poorly dressed or cracked lead flashing is behind more roof leaks than most homeowners realise. We carry out lead work on chimney flashings, valley gutters, dormer cheeks, and flat roof edges across Aylsham and the Norfolk Broads area, cutting and dressing each piece on site for a proper weathertight fit.

Lead flashing seals the joints where your roof meets a wall, chimney, dormer, or another roof slope. When it lifts, cracks, or was never properly fitted in the first place, rainwater tracks straight into the roof space or down inside the wall. It is a common issue on the older brick-built and flint properties found throughout Aylsham and the surrounding villages.
Good lead work is a craft. Each section of lead is cut to length, dressed to the profile of the masonry or tile, and dressed in steps so water cannot run back behind it. We rake out the mortar joint, insert the lead, and repoint with a flexible mortar so the flashing can expand and contract with temperature changes without cracking the joint. We use code 4 or code 5 sheet lead depending on the location, which is the standard for pitched roof flashings and chimney work in the UK.
Lead is heavy, the work is carried out at height, and a poorly fitted flashing can do more damage than no flashing at all by directing water into a cavity rather than away from it. Many of the leaks we trace on older Norfolk properties turn out to be failed lead rather than broken tiles.
We inspect all surrounding lead and pointing when we attend a lead repair, because fixing one section while leaving a failing section next to it means you will be dealing with the same problem again before long. Most lead repairs on a single chimney or dormer can be completed in a day.
Lead flashing repairs on a standard chimney in Aylsham typically cost between £250 and £600, depending on how many sides need attention and the extent of any repointing required.
