Bath's roofs in the valley of the limestone hills
Bath sits in the Avon valley, ringed by limestone hills near the southern edge of the Cotswolds, and rises to 238 m on the Lansdown plateau. The Romans built a temple and baths here around 60 AD and named the settlement Aquae Sulis. Much later, Bath stone, a creamy-gold limestone from Ralph Allen's Combe Down and Bathampton Down mines, gave most of the city's buildings their honey-coloured look.
The Georgian city was laid out by John Wood the Elder and continued by his son, John Wood the Younger, and the population grew from about 2,000 in 1700 to 28,000 in 1801. That is a city built in a hurry, on a plan, within a few generations. Buildings that share walls, rooflines and drainage across whole streets are the natural result, so a leak on one house can start on its neighbour, and a repair on one can affect the next.
Bath was inscribed as a World Heritage Site in 1987, and in 2021 it became part of a second, the Great Spa Towns of Europe. We do not assume what a roof is covered with from the walls beneath it, because the same stone elevation can sit under quite different coverings. We identify each covering at the survey and quote for what is actually on the roof. Planning and listed building decisions here belong to the unitary council.

Chapter 01
John Wood's streets and the roofs that share a wall
A planned city of connected buildings makes neighbours part of every roofing job.
Chapter 01In this chapter
John Wood the Elder laid out many of the Georgian streets and squares, and his son John Wood the Younger continued the work. Whatever a street looked like on the drawing board, it was built as a group of buildings that stand shoulder to shoulder. In a group like that, a roof is not an isolated structure. It shares a party wall with the next house, a chimney stack that serves two fireplaces, and perhaps a gutter run that crosses a boundary.
In this chapter
That has practical effects, and they show up on the day of the survey as much as on the day of the work. A leak that shows in your ceiling may come from the neighbour's flashing or from a shared stack. A repair to your slope may need access through someone else's property. A scaffold may have to be built across more than one frontage, so it is worth asking neighbours early whether they need work too, because sharing the cost of one scaffold between two roofs is often cheaper than building it twice. We raise this at the survey, and where neighbours need work, we price each roof separately so the split is clear.
The best-known problems on terraced roofs are at the junctions. Party walls rise through the roof and carry upstands, copings and flashings. Stacks are built on the wall line and need their own flashings, and the gutters between them may be concealed. When any of these fails, damp appears in a house that looks fine from the street. Our chimney repairs page explains how a stack is rebuilt, repointed and re-flashed.
Coping with a city plan on the quote
The cost of work in a terraced street is usually driven by access, not materials. A street with no rear lane means everything comes through the building or up the front. Parking restrictions may govern where a skip can go, and we plan for that so the waste is cleared away rather than left to build up. All of that goes into the written quote.
Where a stack is shared, we agree the scope with both owners before we start, in writing, and we photograph the junction from each side so everyone has the same record to look at. That avoids disputes about what was there before.
On a terrace, your roof starts at the party wall and ends at your neighbour's.

A World Heritage city and its 5,000 listed buildings
The scale of protection in Bath turns consent into the first step of a roof project.
Chapter 02In this chapter
Bath counts around 5,000 listed buildings. Its city-wide conservation area grew from six small areas designated in 1968, merged into one in 1973, and covers about 1,488.7 hectares. Inside it sit 2,246 entries on the national list, 103 at Grade I, 116 at Grade II* and 2,027 at Grade II, and a single entry often covers a whole terrace. In a city this protected, the first job for any owner is to find out whether the building is listed, because that decides the whole route for the work.
In this chapter
For a listed building, any alteration that would affect its character needs listed building consent from the council. That includes the covering, the ridge, the chimney pots, rooflights and rainwater goods. The council can tell you whether your building is listed and at what grade, and Historic England holds the national list. Carrying out such work without authorisation is a criminal offence under the Planning (Listed Buildings and Conservation Areas) Act 1990.
Unlisted houses in the conservation area carry lighter rules, though they still matter. Re-roofing like for like is normally not development, so permission is not usually needed. New roof features are different, and dormers are not permitted development in a conservation area or on a World Heritage Site, because both count as article 2(3) land. A roof window can remain permitted development with conditions, and our roof window planning page sets out the details.
One practical point for owners of listed houses: ask for the schedule of work to name each element, such as ridge, valleys, flashings and gutters, so the council can compare what is proposed with what exists. A schedule that says only 're-roof' tells the conservation team very little, and it often leads to questions that slow the decision.
Matching the stone and the lead
Because Bath stone gives the city its look, stone repairs and dressings on parapets, chimneys and copings are a visible part of roof work. We do not source or cut stone ourselves in every case, but we survey the condition of what is there and note stonework that is loose, spalled or open at the joints. Where stone and lead meet, the lead is dressed into the joints and the pointing is renewed, in a mortar chosen to suit the stone. On a listed building, the council may specify the mortar and the lead code, and we price to the specification.
Every quote shows VAT. Roofing work to existing buildings is normally standard-rated, and approved alterations to listed dwellings are standard-rated too. The one exception worth knowing is loft or roof insulation installed in a home, which is zero-rated until 31 March 2027.

Chapter 03
From the Avon valley to the Lansdown plateau
A city that climbs from the river to a plateau at 238 m puts roofs at very different levels.
Chapter 03In this chapter
Bath spans the valley floor beside the Avon and the hills above, reaching 238 m on the Lansdown plateau. Roofs in a city like that sit at all sorts of angles to the ground. A house on the valley floor may have a roof you can reach from a short ladder at the back. A house on a hillside terrace may be several storeys higher at the back than at the front, and need a scaffold that is a different height at either end.
In this chapter
The first question on any hillside job is how high the work really is. Height changes the type of scaffold, the number of lifts, the way materials are raised, and the safety measures at the edge of the roof. We measure it at the survey rather than estimate it from the street, because a few extra lifts on a tall elevation add a real cost, and that cost should be on the quote at the start.
The second question is the roof itself, and what it will take to reach every part of it safely. Long runs of gutter, high chimney stacks and valleys hidden behind parapets all need their own access, and a tower scaffold that works for one may not work for another. The city is large, and buildings of many periods stand together: Georgian streets, later houses, flats and shops. A flat roof over a rear extension, a lead valley in a terrace, and a large pitched roof over a block of flats can all appear in the same road. We treat each as its own job, with its own survey notes, because a flat roof, a lead valley and a pitched slope fail in different ways. Our roof replacement page walks through a full strip and re-cover, and our commercial roofing page covers larger buildings, flat roofs and mixed-use properties in a city centre.
Dealing with scale: a city, not a village
Bath had 94,092 residents at the 2021 census. That puts it in a different league from the villages nearby. Larger buildings, flats and shops mean more owners and more people to inform before work starts. Where a roof belongs to a block, a freeholder or a management company has to agree to the scope, and the written survey is laid out so it can be passed to them without rewriting. It names each element, shows a photograph of each, and keeps the access plan in a separate section. For a lettings agent or a landlord, the quote is written element by element, so it can be approved with confidence, and the work can be matched to a photograph of the roof.
The Building Regulations thresholds are the same here as anywhere: a smaller repair stays below them, and a large re-roof may cross them and bring an insulation upgrade with it. Your building control body can confirm where a particular job falls.

Honey-coloured Bath stone and Georgian terraces
How do I find out whether my Bath house is listed before I re-roof it?
Ask Bath and North East Somerset Council, and check the national list held by Historic England. In a city with around 5,000 listed buildings, that check is worth making before you ask for any quote.
My terraced house shares a chimney with next door. Who pays for repairs?
That depends on your deeds and any party wall arrangements, which we cannot advise on. What we can do is survey the stack, photograph it from both sides and give each owner a clear quote for their share of the work.
Can I add a dormer to my loft in the Bath Conservation Area?
Not as permitted development, because the conservation area and the World Heritage Site both count as article 2(3) land. A planning application is needed. Roof windows have a different route, set out on our skylights pages.
Does a hillside house in Bath cost more to scaffold?
It can, because height and ground levels decide the scaffold. We measure the tallest elevation and the foot of the frame at the survey, then put the scaffold on the written quote under its own heading.
