Lead flashing costs vary considerably depending on where it is, what Code is needed, and what else is found once the old lead comes off - here is a plain guide to what drives the price.

Lead flashing and weathering work is not a fixed-price commodity. A simple repair to a lifted section of step flashing costs far less than a full chimney flashing replacement including new soakers and re-pointing. The price you pay depends on the type of junction, the Code of lead specified, the access needed, and what condition the surrounding structure is in. We cover lead work across Dilham, North Walsham, Stalham, Horning, Marsham, Trunch, Mundesley, and the wider Norfolk area, and no two jobs quote out the same way.
This page breaks down the main cost factors honestly, so you can understand a quote - or question one - before agreeing to any work.
The following figures reflect typical UK market pricing for domestic lead work. Every property is different, so treat these as a starting range rather than a firm price for your job.
Lead itself is traded as a commodity and its price fluctuates. Material costs for Code 4 lead sheet typically run at £20 to £30 per square metre, and Code 5 at £25 to £38 per square metre, though these figures move with the metal market. A significant part of any lead work quote is the labour - lead dressing by hand takes time and cannot be rushed without cutting corners.
Several factors add to the base price of lead work, and a roofer should be able to explain each one if it applies to your job.
Access and scaffold: If the chimney stack or dormer is high up on a large property, a simple ladder and roof ladder may not be adequate for the work to be done safely and to a good standard. Scaffold hire adds to the cost - erection and hire for a typical chimney job can add £300 to £800 or more depending on the height and the period it is needed. This is a real cost and should be itemised separately so you can see what you are paying for.
Chimney stack size and complexity: A small single flue stack with straight sides is straightforward. A wide double stack, an angled stack, or one with an unusual profile requires more lead, more time, and more skilled dressing. Some older properties have chimney stacks with corbelled or moulded brick detail that makes forming a tight flashing seal considerably more involved.
The condition of the surrounding masonry: If the brickwork around the chimney is spalled, the mortar joints are open, or the capping is cracked, this work needs to be done before or alongside the lead. Re-pointing a chimney stack or replacing a mortar cap adds cost but is necessary - new lead fitted to a deteriorating stack will not last.
Code of lead specified: Using Code 5 instead of Code 4 for a flat section or valley gutter costs more in materials. It is the right specification for those positions, but the extra cost is real.
Removing previous botched repairs: If a previous roofer applied mortar, mastic, or self-adhesive tape over old failing lead rather than replacing it, removing those materials and preparing the substrate properly takes extra time. Mastic in particular bonds strongly and can be difficult to clean from masonry without damaging the mortar joints.
Soakers versus continuous flashing: A job that involves fitting individual soakers at every tile course (the correct approach for slated or tiled abutments) takes longer than fitting a single continuous stepped flashing. The result is better and the lead will move more freely without cracking, but the labour cost is higher.
Some factors reduce the price, and it is worth understanding these too.
Early action: A small repair caught before the lead has fully failed - for example, re-pointing a chase that is cracking before the section lifts - costs a fraction of what a full replacement costs once water has been getting in and the surrounding timber or masonry has been affected.
Combining jobs: If scaffold is already going up for another piece of roof work, having lead work done at the same time removes the access cost from the lead job entirely. Likewise, if tiles are being stripped near an abutment, fitting new soakers at the same time adds relatively little to the overall cost.
Simple geometry: A chimney with four straight sides and standard brick courses is quicker to flash than a complex profile. A straight valley gutter run is less involved than one with changes in direction or width.
Lead scrap value: Old lead removed from a property has scrap value. A roofer removing a significant quantity of old Code 5 lead from a valley or parapet gutter will typically account for this when pricing - or should do if they are being straightforward.
When reviewing a quote for lead work, check that the following are either included or specifically excluded and priced separately:
A quote that does not mention these items is likely either assuming they are not needed (which should be confirmed) or leaving them out to appear competitive, to be added as extras later. A clear written breakdown of what is and is not included protects you from bill creep.
An accurate price for lead work cannot be given over the phone without someone getting eyes on the job. The condition of the existing lead, the state of the masonry, the access required, and the specification needed all have to be assessed in person. Call us to arrange a roof survey for your property in Dilham or the surrounding area, and we will give you a clear breakdown of what the work involves and what it will cost before anything is agreed.
