Lead work keeps water out of the most vulnerable joints on your roof - around chimneys, dormer windows, and valleys. We cut, dress, and fit lead flashing to traditional standards, giving you a weathertight seal that will last for decades rather than years.
Lead flashing is the most durable waterproofing solution available for the complex angles on a roof - where a chimney stack meets the tiles, where a flat roof abuts a wall, or where two roof slopes meet in a valley. Properly installed lead work on a Norfolk property can last fifty years or more. The problem is that it needs to be cut and dressed by hand to fit each joint precisely, and shortcuts taken with incorrect grade lead or sloppy pointing create leaks that can damage ceilings and timbers well before you spot them from outside.
Our lead work covers step flashing up chimney stacks, soakers behind abutment walls, valley liners in Code 4 or Code 5 lead depending on exposure, flat roof upstands, and bay window leadwork. We chase the lead into the mortar joint on brickwork rather than simply sticking it to the surface, then repoint with a lime-compatible mortar that allows the building to breathe. Every section is dressed to shape on site using a bossing mallet and wood dresser so it sits flush and tight.
Using a general builder or handyman for lead work is a gamble. Lead needs to be fixed with the correct clips and sized correctly to allow for thermal expansion - lead that is fixed too rigidly will split or pull away from the joint within a few years, especially during the temperature swings we get between a Norfolk summer and winter.
We assess the existing leadwork first and replace only what is necessary, keeping costs down where we can. Most chimney flashing replacements on a standard stack take half a day to a full day on site. We carry our own lead stock so there is rarely a waiting time for materials.
Lead flashing replacement around a standard chimney stack in Downham Market typically costs between £350 and £700, depending on the number of faces and the size of the stack.
