Roofs in a Mole Valley village of half-timbered cottages and chalk.
Betchworth lies between Dorking and Reigate, with a Grade II* house, old cottages and a chalk-built church. We survey the roof, share photos of your own slopes, and quote one written price.
In 1911 the Victoria County History described a village street of old cottages, some half-timbered, approaching the church. Cottage roofs like these meet walls at awkward angles, so flashings and chimney junctions get our closest look.

The Old House is listed Grade II*, and April Cottage, Ravenleigh Cottage and Broome Park are Grade II. On a listed roof we ask the council before work and keep to the same materials.

The Victoria County History recorded chalkpits, limeworks and brickyards in the parish. That tells us what the parish made, not what covers your roof, so we read each slope, ridge and gutter as we find it.

Working in Betchworth
Three short chapters on how the parish grew from chalk and brick, what listing means for its older roofs, and which Mole Valley and Surrey bodies matter once a job grows.
Stage 01 · Background
Quarrying, lime burning and brickmaking shaped the parish, yet a village's history is no guide to any single roof.
In 1911 the Victoria County History said chalk furnished the parish's chief industry. Chalkpits and limeworks had existed time out of mind, and the Dorking Grey Stone and Lime Company burnt lime and made cement here on a large scale. There were brickyards too. The parish church is built of chalk rubble quarried from the neighbouring hills, with dressings of clunch and firestone. It is a lively picture of a working landscape, but it describes the parish a century ago, not the roof above your kitchen.
We begin on the ground, walking round the house and looking up at the slopes from the lane and the garden. Missing or slipped tiles, a sagging ridge line, stained brickwork under the gutters and moss thick on one slope are all clues. Then we go up, check the covering, the fixings and the junctions at chimneys and walls, and look in the roof space for daylight, damp and timber that has gone soft. You get the photos, and the plain-English account that goes with them. Nothing is left to memory, which matters if you want to show the same pictures to a neighbour, a landlord or the council.
First checks on a Betchworth roof
Not as a rule, and a postcode settles nothing. What matters is the covering and how it has been looked after. Marley quotes around 60 years for concrete tiles and states that this is not a guarantee. The Building Research Establishment sets clay tile at 60 years minimum, but old peg tile can fall outside that. Slate, if maintained, can last over a century. Nails, bedding mortar and lead often need work before any of that.
It follows that a repair can be the better buy before a renewal is on the table. A few replacement tiles, new bedding on a hip, or a refixed flashing can add years at a fraction of a new roof's cost. If the survey shows a slope has reached the end, we tell you straight and show you the evidence. Our pitched roofing page describes how we mend tiles, battens and underlay, and our roof replacement page explains a full renewal from strip to ridge. If the chimney stack is leaning or the pointing has crumbled, we photograph that too, because a failed stack can let in as much water as a missing tile.
Stage 02 · Consents
A parish with a Grade II* house and several Grade II buildings means some roof jobs need the council's agreement before work starts.
The Old House was first listed Grade II* on 11 November 1966. April Cottage and Ravenleigh Cottage share a Grade II entry, and Broome Park is Grade II as well. The same history noted old cottages, some half-timbered, along the street leading to the church. Older houses like these are the ones where a roof job can involve more than the roofer.
Section 7 of the 1990 listed buildings Act bars unauthorised works that would change the special character of a listed house or cottage. Whether a particular repair crosses that line is for the council to decide. For Betchworth that is Mole Valley District Council, so put your question to its planning team and attach our survey photos so they can see exactly what is proposed. Our page on re-roofing a listed building describes how these conversations tend to unfold.
Old-house words explained
The roof often has to be worked around an exposed frame, steep slopes, dormer cheeks and low eaves, and each joint between roof and wall is a spot where rain looks for a way through. In those spots lead does the waterproofing, in soakers, valleys and flashings. Sheet lead comes in numbered codes, and a thicker sheet is normally chosen for a valley than for a small soaker. Where the chimney is the weak point, our chimney repairs page shows how flaunching and flashings are renewed.
We repair in the materials already there. That means matching the size, thickness and colour of the tile, bedding ridges in a way that suits the roof and, where the building is listed, showing the council samples first. If a part has failed, you see the old piece and the new one side by side before the order goes in. On a cottage with a low eaves line or a low porch roof, we also plan how the scaffold or ladders will reach it without touching the walls, and how waste will leave the site without crossing a neighbour's garden.
On a listed roof, the council's answer should be in hand before the scaffold goes up.
The government's planning dataset holds a Betchworth conservation area supplied by Mole Valley, lying south of the station around the old village, so check whether your address falls inside before changing how a roof looks. Listed status is separate, and attaches to individual houses.
Stage 03 · Permissions
Mole Valley handles planning and the Southern Building Control Partnership handles approvals, while Surrey County Council licenses scaffold on its roads.
A small repair seldom reaches a council desk. The picture changes when a whole slope is renewed, when the old covering gives way to a new material, or when scaffolding has to stand on public land.
Building control for Mole Valley is run by the Southern Building Control Partnership, which Mole Valley shares with Reigate and Banstead and with Tandridge. The Planning Portal's rule of thumb is that no application is normally needed when less than 25 per cent of the building envelope and less than 50 per cent of the roof is affected. Weight is a separate trigger. A replacement covering that is 15 per cent heavier or more does call for approval, and the Planning Portal tells owners to consult a structural engineer or surveyor before they begin, a step we build into the survey. We run that comparison for you, old covering against new, and the written price carries the result. If we reckon a slope will qualify, we tell you at the survey so the timing can allow for it.
Bigger job checklist
If scaffolding must stand on a public road or pavement, a licence from the highway authority is required, and in Surrey that is the county council. Surrey's page gives £208 per 28 day period and asks you to apply at least 10 working days before the date you need. Because the licence takes time, the survey comes early. Surrey leaves open who submits the form, so we settle that with the scaffolder and choose our own start date once the permit is secured. If the scaffolding can stand on your own ground, no highway licence applies. Checkatrade's October 2026 roof replacement guide gives £700 to £1,300 for a new roof's scaffold, which is why any quote should say whether scaffolding is included.
Bats and the places they roost have legal protection, and GOV.UK lists repairs to a roof among the work that may disturb them. Birds are covered as well, since the 1981 Wildlife and Countryside Act forbids intentionally destroying a nest that is occupied. When a roof space shows droppings, staining or a nest, work pauses. We explain what we have seen and agree the way forward with you, because the animals come first.
The first step is simple. Photograph the slope, valley or chimney you are worried about, and send it with your Betchworth postcode.
The tiling is the same craft, but the junctions are harder. A roof worked around an exposed frame has more places where water can enter, so flashings, valleys and chimney joints take longer. If the cottage is listed, speak to Mole Valley District Council before work starts and send them the survey photos, so the planning team can see exactly what is proposed.
The Old House is Grade II*, and April Cottage, Ravenleigh Cottage and Broome Park are Grade II, according to the National Heritage List. Other buildings may be listed too, so check the National Heritage List entry for your own address before you plan any roof work. For work on any listed house, the council decides whether consent is required.
Only if the scaffolding stands on the public highway. Surrey County Council asks for at least 10 working days' notice and charges £208 per 28 day period. On private ground, such as your own drive, no highway licence applies. We sort out the paperwork with the scaffolder, then set the start date once the licence is in place.
Yes. It is the building control team for Mole Valley District Council, alongside Reigate and Banstead and Tandridge. Approval for a re-roof depends on the share of the roof renewed, plus any extra weight in the new covering. Put the question to the team first. We raise it again at the survey, and again if the plan changes.
Send a photo of the slope, valley or chimney that concerns you, plus your Betchworth postcode, and a survey date will follow.
