What Lead Work Actually Costs - and Why it Varies

Lead work is one of those jobs where quotes can vary significantly between roofers, and it is not always obvious why. Understanding what drives the cost helps you assess whether a quote is reasonable, whether something has been left out, and whether a cheaper price means a simpler job or a corner being cut.

Typical Price Ranges for Common Lead Work Jobs

The figures below are honest typical UK ranges. They are not fixed prices - every roof is different - but they give a useful starting point for Great Shelford homeowners comparing quotes.

• Repointing and re-wedging existing lead flashings: £150 to £350. This applies when the lead itself is sound but has dropped because the mortar joint has failed or the wedges have come loose. It is the least involved lead work repair.
• Partial chimney flashing repair (one or two sections): £200 to £500. Replacing a section of step flashing, a cover flashing, or the lead soakers on one side of a chimney stack.
• Full chimney flashing set in new lead: £600 to £1,400. This covers a complete set including back gutter, step soakers on both sides, and a cover flashing for a standard single chimney stack. Larger or more complex stacks sit at the higher end.
• Dormer lead work: £300 to £800. Side soakers and a base apron on a standard dormer. A large dormer with a lead cheek or valley detail will cost more.
• Flat roof abutment flashing: £200 to £600 depending on the run length and whether a new lead flashing or a replacement upstand detail is needed.
• Bay window flat roof lead work: £250 to £600 for a standard bay, depending on condition and accessibility.

These prices are for the lead work itself. Scaffolding is costed separately where it is required.

Scaffolding - the Cost That is Often Missed

Most chimney lead work requires scaffolding. A chimney stack is, by definition, above the ridge, and a roofer working from a ladder at that height cannot work safely or accurately on all four sides of a stack. For most domestic chimney jobs, a scaffold platform adds £350 to £700 to the overall cost.

Some homeowners are surprised when they get a full chimney lead work price that includes scaffold and find it is significantly higher than a quote that did not mention access. If a quote does not mention how the roofer plans to access the chimney, ask specifically. Work done from a ladder on a chimney that needs scaffold is a red flag, not a saving.

For lower-level work - a bay window, a rear extension flat roof, or a ground-floor dormer - a tower scaffold or hop-up may be enough. These add less to the overall cost, typically £100 to £250.

What Pushes the Cost Up

Several factors mean a lead work job will sit at the top of a price range rather than the bottom:

• Stack size and complexity: A large double chimney stack with multiple flues, or one with a complex profile, takes significantly more lead and more time than a standard stack. A back gutter that runs across the full width of a wide stack, or one that needs a separate lead-lined gutter box, adds cost.
• Height and access difficulty: A chimney on a three-storey property or at the end of a long terrace needs more scaffold and more time to erect it safely. Height affects both cost and the time the scaffold is on hire.
• Secondary damage: If the lead failure has been present for some time, the timber behind the flashing may be wet or partially rotted. Replacing a section of fascia board, a batten end or a rafter tail while the scaffold is up adds to the job but avoids a separate future visit.
• Brickwork condition: A chimney stack with deteriorated pointing, spalled bricks or a cracked flaunching (the mortar cap around the pots) ideally has those repairs done at the same time as the lead work. Repointing a chimney stack while the scaffold is already up costs much less than erecting scaffold again later.
• Higher Code lead: Code 5 lead costs more than Code 3 per square metre. If your location demands a heavier Code and a roofer quotes using a lighter one, the cheaper price is not like-for-like.
• Removal of previous repairs: If a previous roofer has applied self-adhesive flashing tape or mastic over the original lead, stripping this back properly adds time. Skipping it leads to an inadequate bond for the new work.

What Keeps the Cost Down

A straightforward job has straightforward costs:

• A single standard chimney stack on a two-storey house with no secondary damage is the most common and most predictable lead work job.
• Work that can be reached from a tower scaffold rather than a full tube-and-fitting scaffold is cheaper to access.
• Combining lead work with other roof repairs during a single scaffold visit - replacing a few slates, repointing the flaunching, clearing a gutter - spreads the access cost across multiple tasks and reduces the overall spend per job.
• Catching the problem early, before water has been tracking into the structure for years, avoids secondary timber repairs that add significantly to the total.

Comparing Quotes - What to Check

When you receive quotes for lead work, check that each one specifies the same scope. A quote that does not mention scaffolding for a chimney job may simply have left it out. A quote that does not specify the Code of lead being used may be pricing lighter material than the job requires. The right question is not just "how much?" but "what exactly is included?"

A written breakdown showing access method, Code of lead, sections being replaced, and any ancillary work is the clearest basis for comparison. If one roofer cannot explain why their price is lower than another's, that is worth taking seriously.

Is a Full Replacement Always Necessary?

Not always. If the lead is in sound condition and the failure is at the mortar joint only - a common situation on older properties - repointing and re-wedging at the lower end of the price range can restore a watertight seal for a fraction of a full replacement. A roofer who recommends full replacement on lead that is structurally sound is not giving you the most cost-effective advice.

The test is whether the lead itself has cracked, thinned or pulled away at the folds, or whether it has simply become unfixed at the top. The former needs replacement; the latter may need only repointing.

Getting a Roof Survey Before Lead Work Starts

If you are comparing lead work quotes in Great Shelford or the surrounding area, ask for a roof survey before any work starts. A good roofer will tell you what the job involves and what it is likely to cost before committing to a price.
