Lead turns up on almost every old roof worth protecting: the flashings round a chimney, the soakers hidden under slates, the valley between two gables, the covering on a bay. When that metal wears out, the owner of a listed house or a building in a conservation area has a second question to answer beside the usual one of cost. Is the planned repair the sort that needs permission?
This guide deals with that question for leadwork only. It covers what protection means for a roof, how a like-for-like renewal is judged, the route to consent, and why the council may not accept a substitute. Products in general, from GRP to zinc, are compared in our guide to lead alternatives. For the wider service, see our lead roofing page.
What protection means for a lead roof in the Stroud area
Three different kinds of protection can apply to a roof round Stroud, and they work differently. Finding out which one you have is the first step.
Listed buildings
On the council's reading, Grade II is protected just as firmly as anything higher, and protection extends to the whole building, rear and interior included. The roof and every piece of metal on it come under that. Outbuildings and walls in the grounds can be caught too, and the council's conservation officers can say whether each is covered.
Conservation areas
The district has 41 conservation areas, running from Painswick and Uley to the mill complexes along the valley floors. Living in one does not make a house listed, but the area brings extra planning controls, and five of them also have Article 4 Directions (Bisley and Frampton on Severn among them, with Wotton Under Edge and two parts of Stroud). The published guidance leaves open whether roofs are within their reach, so we suggest ringing the planning team before work starts.
The Cotswolds National Landscape
Just over half of Stroud District lies within the National Landscape, formerly the AONB. The designation does not by itself stop you renewing lead like for like, but it affects larger changes such as new dormers.
Like for like: how a repair is judged
Section 7 of the 1990 listed buildings Act forbids altering a listed building in any manner that affects its special architectural or historic character unless the work is authorised, and section 9 makes breaching that an offence. Repairs that match what was there are generally treated differently from alterations that change it, but the line is drawn by the council, not by the contractor.
What matching means
For lead, matching covers more than the metal. It includes the thickness, the way sheets are jointed, the pattern of rolls and drips on a flat area and the shape of flashings where they meet masonry. A roof that had rolled lead in bays should come back with rolled lead in bays, not a welded membrane that only looks similar from a distance.
Changing the code
Leadworx treats Code 4 as the everyday weight for flashings, while Royston's cast lead brochure shows heavier codes for the bigger or more demanding parts of a roof. Moving to a different code on a protected building can be sensible when the old lead has been too thin to last, but it is a change, and we raise it with you and the council rather than assuming it.
When it is plain repair
Re-dressing a lifted flashing, replacing a few split soakers and re-pointing a cover flashing into the same mortar joint are the kind of repair the council would normally see as maintenance. Even so, a quick call to the conservation team is cheap, and it puts the agreed scope on record.
Asking for consent: who decides and what we provide
Listed building consent is granted by the local authority. For houses in Stroud District that means the council's conservation and planning staff, and for properties across the border it means Cotswold, Gloucester City, Tewkesbury or Forest of Dean, each with its own pages. We do not decide whether consent is needed, and we do not approve our own work. What we can do is make the case easy for the council to understand.
The paperwork behind a request
Most councils look for a clear description of the problem, photographs of the existing leadwork, and a specification of what will replace it. During the survey we photograph each flashing, valley, cheek or bay on your own roof, note its type and condition, and write the proposed repair in plain terms: metal, code, jointing method and fixings.
Why this matters before the quote
If consent is needed, the date it comes through governs when scaffold can go up and when the work starts. We build that into the planning for you, along with the access difficulties of a steep lane or a terraced hillside, and the first morning on site is not the first time anyone hears about the lane.
Building Regulations alongside
Consent from the conservation team is separate from Building Regulations. A repair to leadwork on part of a roof usually falls within the Planning Portal thresholds of under 25 per cent of the building envelope and under 50 per cent of the roof, but a larger renewal can go beyond them. If the job is notifiable, we write to building control and explain what they need.
If a council officer visits and agrees the scope in writing, keep that email with your roof records. It is useful when you sell, and when the next owner has to renew the lead.
Why a substitute may be refused
Lead is expensive, and every year some owners ask whether a lower-cost product could go in its place. That question deserves a straight answer: on a protected building the answer is often no, or not without a discussion.
Appearance
Lead weathers to a dull grey and sits tight to stone and slate. Many alternatives are flatter, shinier or brighter, or simply look different in the fold of a valley. Because the legal test is the effect on the building's character, a finish that looks out of place can be enough to fail it.
Behaviour over time
Lead can be worked by hand to fit any shape, and it can be repaired repeatedly. A substitute product may be harder to adapt to an irregular stone parapet, and joints may behave differently as the building moves.
Reversibility
Conservation thinking favours work that could be undone. RICS reasons this way about spray foam, saying it cannot be reversed and probably will not get consent for a listed building. A product fixed for good to old fabric draws the same objection.
The wider principle
Look at how stone slate roofs are treated. An English Heritage policy quoted in Cotswold District Council's 2000 guidance rejects artificial slate substitutes for historic buildings. That concerns slates, not lead, but it shows the starting point conservation staff use: the original material. Our guide to lead alternatives explains the products, though only the conservation officer can say whether a given product would be accepted on your building.
Old lead on a listed roof: recording before stripping
Lead that has been on a roof for a long time can itself be of interest. Royston's brochure describes cast lead as a traditional product, and a very old sheet may be thicker and differently made from today's rolled lead. Ahead of any stripping, we record the roof as it stands, noting the pattern of the joints, the position of rolls and drips, and any marks, dates or initials scratched into the metal.
Should it be kept?
That is a decision for the conservation officer. In some cases old lead can be cleaned, repaired and reused; more often it has thinned or split beyond reuse. Either way, it should not simply go into a skip without a conversation. Old lead is worth money as scrap, so ask the council first and have the decision recorded.
The condition of the structure
Old leadwork often hides old timber. On a listed roof we are careful with rafters, boards and decking, because repairing them in place is usually preferred to replacing them. Where boards must be renewed, we record what comes out and what goes in.
Lead theft
If the lead has been stolen, the urgency is real because an open roof lets the weather in. The first job is to make the roof safe and weathertight, and the council should be told that the leadwork is missing. What replaces it is again a matter of agreement. Our lead theft guide covers prevention and replacement.
Churches, chapels and farm buildings
Not every protected roof is a house. The valley has churches, chapels, mills and barns, and the rules differ among them.
Churches in use
A church that still holds services sits outside listed building consent altogether, under what the law calls the ecclesiastical exemption. In the Church of England the diocese's court grants a faculty for roof work instead. The parish's architect will know how that goes.
Redundant churches and converted chapels
That freedom ends with the worship. When a church closes its doors or a chapel is made into a dwelling, the council's consent route normally applies, and lead repairs follow the path used on any listed house.
Mills and barns
Stroud's industrial past is reflected in the conservation area list, where Dunkirk Mills, Ebley Mills and Longfords Mills each have an entry. The lead on a mill roof, in valleys and parapet gutters, may be on a bigger scale than a house, which affects access and cost. Barns and outbuildings within a listed house's grounds may be protected too, and the council advises checking their status.

Costs, patination and what to expect from us
Costs on a protected building follow the same national ranges as any lead job, with extra time for consent and access. MyJobQuote, updated September 2026, gives a chimney flashing patch at £150 to £250, and full replacement at about £570 on average. Checkatrade gives lead flashing repairs at £50 to £70 per metre and stepped flashing at £80 to £120 per metre in Code 5, excluding VAT. MyBuilder puts lead flat roofing at £150 to £200 or more per m². These are national figures from third parties, and what you pay is set after the survey. See lead flashing cost for the breakdown.
Finish and colour
New lead is bright when it goes on, and on a protected roof the first few months matter. A patination treatment helps the metal weather evenly to a grey that blends with its neighbours; see patination oil for how it works. On a listed building we mention the finish to the conservation officer when we describe the work.
Bays and porches
Small lead roofs are common on protected houses, and they often form the only visible leadwork from the street. Our guide to lead bay and porch roofs covers their typical faults.
After the visit you get a quote that gives scaffold, stripping, the metal itself, which code it is, the labour, clearing away rubbish and making good a figure apiece. We back the work with a written guarantee covering ten years of workmanship, and on completion the site is left tidy. Our number is 01453 933613, and WhatsApp or the enquiry form reach us too. Please say whether the building is listed.
