What Lead Work Is and Why It Matters

Lead is used at every junction between a roof and a wall, chimney, dormer or parapet - anywhere two surfaces meet and water needs to be turned away. Done well, it outlasts virtually every other part of the roof. Done badly, it is one of the most reliable causes of serious water ingress into a property, often going unnoticed until the damage inside is significant.

The work covers lead flashing, stepped and cover flashings, back gutters, valleys, soakers placed under each course of slate or tile at an abutment, and lead-lined gutters on period properties.

Whether the job is a new installation on an extension or a repair to failing flashings around a chimney stack, the standard of the work is what determines whether it holds. This page focuses on one specific question: how do you choose a contractor for lead work, and what should you ask before you agree to anything?

Why Choosing the Right Contractor for Lead Work Matters More Than Usual

Lead work is a skilled trade within a trade. A roofer who can competently tile or slate a roof may have limited experience with lead, and vice versa. Poor lead work is not always immediately obvious - a flashing can look neat from the ground and still be incorrectly fixed, under-thickness, or missing expansion joints that will allow it to crack within a few years.

Unlike a poorly laid tile, which tends to fail quickly and visibly, a badly dressed flashing may hold for one or two winters before the cracks open up or the pointing fails. By that point the homeowner has often forgotten who did the work, or the contractor is no longer easy to reach. Choosing carefully at the outset is the most effective protection you have.

Questions to Ask Before You Agree to Any Lead Work

These are the questions worth putting to any contractor before signing anything or paying a deposit. A confident, experienced tradesperson will answer them clearly. Evasion or vagueness is itself useful information.

• What lead code will you use, and why? Different applications require different thicknesses. Code 3 is suitable for soakers; Code 4 is the minimum for flashings and valley linings in most situations; Code 5 is used for back gutters, parapet gutters and other demanding applications. If a contractor cannot tell you what code they plan to use, that is a concern.
• How will you handle expansion joints? Lead moves with temperature. Individual bays of lead flashing should not exceed around 1.5 metres in length without an expansion joint. Longer bays will crack through thermal stress. Ask specifically how bays will be formed and joined.
• How will the flashing be fixed into the wall? Correct fixing uses lead wedges driven into the raked-out mortar joint, followed by a proper repoint in an appropriate mortar. Nailing through the face of the flashing into the wall is not correct practice and will fail.
• Will you rake out and repoint the mortar chase? The lead sits in a chase cut or raked into the mortar joint. If that chase is not cleaned out and properly pointed after the lead is fixed, water will track behind the flashing regardless of how well the lead itself is dressed.
• What happens if you find damaged timber underneath? Flashings that have been leaking for any period may have allowed water to reach rafter ends or battens. Ask how this will be handled and whether it would be included in the quote or charged separately.
• Do you work to BS EN 12588? This is the British Standard for milled lead sheet in building. A contractor who has not heard of it, or who cannot explain what it means in practice, is not someone you want doing this work.
• Can you show me examples of similar lead work you have done? Photos of completed chimney flashings, valleys or abutment work on comparable property types give you something concrete to assess. You are looking for neat bay formation, visible expansion joints where they should be, and clean pointing.

Red Flags to Watch For

Some indicators should make you pause before agreeing to anything:

• A quote given over the phone or from the ground without a proper roof-level inspection. Lead work cannot be accurately assessed or priced without getting close to it.
• Unusually low pricing. Lead is a significant material cost. A quote that seems very low is likely to involve under-thickness lead, skipped expansion joints, or surface-only repairs that will not last.
• Proposals to use sealant tape, lead-effect tape, or mortar fillet as a permanent solution. These may serve as temporary measures but they are not a substitute for correctly fitted lead.
• No discussion of access. Chimney work on a two-storey property requires scaffold or at minimum a secured ladder arrangement. If no one mentions access, ask directly how they plan to work safely.
• Pressure to decide quickly or pay a large deposit upfront before any work begins.

What a Properly Done Lead Flashing Job Looks Like

Once the work is complete, you should be able to see clear evidence of how it was done. The lead should be laid in bays with visible joints between them - not one continuous length running the full width of a chimney or abutment. Where the lead turns into the wall, the mortar joint should be freshly pointed and flush. The lead itself should be neatly dressed to the shape of the tiles or slates beneath it, without visible gaps or lifting edges.

A back gutter behind a chimney stack should hold water and direct it to the sides - ask whether this was checked before the scaffold came down. Step flashings on a sloping abutment should be individually soaked and lapped correctly so water cannot work back up under them.

If you can see the work clearly and it looks tidy and methodical, that is a reasonable sign. If the lead has been bent roughly into place, there are no visible bay joints, or the mortar pointing looks smeared over the top rather than properly packed, those are grounds to raise questions before the invoice is settled.

Older Properties and Lead Work in This Part of Norfolk

Many homes in Heacham and nearby have original lead work that is decades old. In some cases that lead is still fundamentally sound and needs only targeted repair rather than full replacement. Original lead that has adequate thickness, no significant cracking, and correctly formed bays can often be re-fixed and re-pointed rather than stripped out.

Where the original work is beyond repair - thinned through oxidation, cracked along multiple bays, or covered in layers of old sealant - a full strip-and-relay is the honest answer. We will always tell you which applies and why, rather than defaulting to the more expensive option.

On listed properties or those in conservation areas, there may be specific requirements about materials and finishes. Lead is generally the only accepted material in those situations, which is one more reason to use a contractor who understands it properly.

Getting a Survey Before You Commit

Because lead work is difficult to assess from the ground, a roof survey before any quotation is the correct starting point. This lets the contractor assess the code of lead in place, the condition of the mortar chase, whether any underlying timber has been affected, and exactly how many bays of new lead will be needed.

If a contractor is not willing to get on the roof to look before quoting, ask yourself what they are actually pricing. A meaningful quote requires a proper inspection.
