Honest advice
Do You Actually Need Roof Replacement?
A full re-roof is the right call when repairs stop being economical — when fixings have failed across the whole slope, the underlay has perished, or you're throwing good money at a roof near the end of its life.
Slates slipping repeatedly across the whole roof, not just one spot
When it is not the answer: If the slate itself is sound and only the fixings have gone, a strip-and-relay reusing your original Welsh slate is often better value than a full replacement — and keeps a heritage roof authentic. Read the full guide.

Heritage Roofing in Bath
Listed and Conservation Roofing Across Bath
Bath is unique among English cities: the entire city is a UNESCO World Heritage Site, and it contains one of the highest concentrations of listed buildings in the country. That makes heritage roofing not a niche specialism here but the mainstream — a large share of Bath's roofs are on listed or conservation-area properties where the materials and methods are controlled by planning law, not left to preference. Getting this work right requires knowledge of the fabric, the materials, and the local authority's requirements.
Heritage roofing differs from ordinary roofing in almost every respect: the slate must be matching natural Welsh slate rather than a cheaper substitute; the mortar must be NHL lime rather than cement; the leadwork must follow traditional detail and code; and the whole approach must be repair-first, conserving original fabric wherever possible rather than stripping and replacing. On a listed building, doing otherwise is not just poor practice — it is a criminal offence under conservation law.
Conservation Areas
Bath's Conservation Areas and Listed Roofscape
The Bath conservation area covers the historic core and extends across much of the city, taking in the great Georgian set pieces and the residential terraces around them. The Circus and the Royal Crescent, the Georgian townhouses of Great Pulteney Street and the Bathwick estate, the terraces climbing Lansdown and Camden, the riverside and canal-side properties of Widcombe, and the Victorian and Georgian stock of Larkhall and Walcot all sit within conservation designation. Across these, the roofscape — the slate, the stone chimney stacks, the lead, the parapets — is part of what the designation protects.
Listed building density in central Bath is exceptional. Grade I and Grade II* set pieces sit alongside long runs of Grade II terraces, and on any of these the roof is covered by the listing. Work affecting the character of a listed roof — which includes re-covering, changing materials, and often significant repair — requires listed building consent from BANES before it begins. We advise on when consent is needed and liaise with the conservation officer as part of the job, rather than leaving owners to navigate it alone.
The dominant historic material is natural slate — largely Welsh slate brought in during the Victorian expansion — over the earlier stone-slate and clay of the Georgian and pre-Georgian core. Sourcing matching slate, whether new Welsh slate or reclaimed to match a specific weathered roof, is central to heritage work here, and it is one of the things that separates a conservation-grade roofer from a general one.
Leadwork
Traditional Leadwork on Bath's Heritage Roofs
Lead is fundamental to Bath's heritage roofs, and traditional leadwork is a core part of heritage roofing in the city. The Georgian terraces in particular depend on lead: concealed box gutters and parapet gutters behind the stone balustrades, lead valleys between roof slopes, lead flashings where roofs meet chimneys and party walls, and lead-covered bay tops and porches. Much of this original lead is now at the end of its serviceable life and needs renewing to the same traditional detail.
Correct leadwork is specified by code — the thickness of the lead sheet, from Code 4 through Code 6 depending on the application — and installed in bays no longer than 1.5 metres to allow the metal to expand and contract without splitting. This is not a detail that can be shortcut: oversized bays of lead fatigue and crack within years, which is precisely why so much replacement leadwork is needed on Bath's period roofs where earlier work ignored the bay-length rule. We install lead to Lead Sheet Association standards, with proper welts, drips and rolls.
On Bath stone, leadwork carries one extra local requirement: patination oil. Newly laid lead, if left untreated, weathers unevenly and washes a white carbonate stain down the honey-coloured Bath stone beneath it — a disfiguring and avoidable mark on a heritage frontage. Treating new lead with patination oil on installation prevents this, and it is a standard part of how we finish leadwork on the city's stone buildings.

Historic England & SPAB guidance: Historic England and SPAB guidance both hold that repairs to historic roofs should be like-for-like in matching materials — natural slate, lime mortar and lead to traditional detail — as modern substitutes damage the fabric and breach listed-building controls.

Access
Getting Safely onto Bath Roofs
A full re-roof always needs scaffold for safe working and to protect you and passers-by; it's included and itemised in your quote. Scaffold is specified for: the entire job — full perimeter scaffold is standard on any re-roof - always itemised in your written quote, never a hidden extra, and we arrange it.
Bath's Georgian and Victorian terraces mean tight pavements, controlled parking, and rear-access scaffold on many streets. Pavement scaffold and skip permits go through Bath & North East Somerset Council; allow a few working days on streets like Milsom Street, Broad Street, Margaret's Buildings where space is tight.

How much original slate can be salvaged and reused
Worked example: A full re-slate of a 1930s semi in Oldfield Park, reusing sound original slate with new matching slate for the shortfall: around £11,500 including scaffold, new membrane and leadwork.
Staged payments on re-roofs — nothing up front before materials are on site, a payment at strip stage, balance on completion. Re-roofing an existing home usually qualifies for reduced 5% VAT, confirmed in writing at quote stage.

The complete re-roof carries a 10-year workmanship guarantee in writing; slate, membrane and other materials carry their own manufacturer warranties on top.
Covered: workmanship for 10 years, in writing, transferable if you sell.
On top: manufacturer warranties on materials (terms vary by product).
Not covered: storm or impact damage - that is an insurance matter, and we will document it for your claim.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
Good to know
What It Is Like While We Work
A re-roof means scaffold up for the duration, skip on site, and some noise during the day — but external work rarely needs you home, and we protect your garden and drives throughout. You do not need to stay home for external work - we just need power and access agreed in advance.
We never strip more than we can make watertight in a day, and temporary covering goes on every night, so your home stays protected throughout. Bath's valley setting holds humidity, so north-facing slopes dry slowly and moss builds up through autumn.

What Bath Homeowners Say
★★★★★
Grade II townhouse with failing lead box gutters. They knew exactly what they were dealing with, renewed the lead to proper bay lengths and treated it so it wouldn't stain the stone. Conservation officer was satisfied throughout.
Charles W., Bathwick
★★★★★
Re-slated our listed terrace in matching Welsh slate. They handled the consent side and sourced slate that blends with the neighbours perfectly. Genuine heritage knowledge, which is rare.
Eleanor R., Lansdown
★★★★★
Lime repointing and slate repairs on a period cottage. Used the right materials throughout — lime not cement — and explained why it mattered for the stone. Proper craftsmen.

Common Questions
Frequently Asked Questions
If your property is listed, work affecting the roof's character — re-covering, changing materials, or significant repair — usually requires listed building consent from BANES before it starts. We advise on when consent is needed and liaise with the conservation officer for you.
On visible roof slopes in a conservation area, natural Welsh slate is typically required rather than synthetic substitutes, with NHL lime mortar rather than cement and traditional leadwork. Bath's UNESCO World Heritage status means these standards are actively enforced.
Bath stone is a soft limestone that must breathe. Cement mortar traps moisture and causes the stone face to spall and erode irreversibly. NHL lime mortar flexes with the stone and lets it breathe, which is why it is the only correct and compliant choice on heritage stonework.
Yes. We source matching natural Welsh slate, either new or reclaimed to match a specific weathered roof, so repairs and re-slating blend with the existing roof and satisfy conservation requirements. Matching is central to heritage work in Bath.
Patination oil is applied to newly laid lead to prevent it weathering unevenly and washing a white carbonate stain down the Bath stone below. On the city's honey-coloured stone frontages it is essential, and we apply it as standard when installing new lead.
Yes. On listed and conservation work we liaise with the BANES conservation officer as part of the job, advising on consent, providing specifications, and ensuring the work meets the authority's requirements so owners are not left to navigate the process alone.
Correctly installed lead — the right code, laid in bays under 1.5 metres with proper welts and drips — lasts many decades, often outliving the roof covering around it. Most lead we replace failed early because it was laid in oversized bays that fatigued and split.
