Roofs around the Wandle springs and the old village High Street.
Carshalton grew around spring-fed ponds on the north side of the chalk downs. We check its tiles, dormers, leadwork and gutters, then send one written price.
The Victoria County History noted in 1912 a row of 18th-century red brick cottages with dormer windows in their tile roofs, east of the church. Dormers are small roofs of their own, so they get a close look.

The same survey recorded that many older cottages were of timber. Where a roof meets a timber wall the junction needs patient work, and we tell you what we find there before we write a price.
Old cottage roof and chimney
19 Park Hill is Grade II*, and Carshalton House and the Church of All Saints share that grade. A roof under a listing needs the council's view first, so our survey comes before any date is booked.

Notes on Carshalton roofs
Three chapters on the water that shaped the village, the conservation area and listed houses, and the questions Sutton puts to a bigger roof job.
Stage 01 · Setting
Strong springs feed the Wandle at Carshalton and fill clear ponds in the village, so we watch closely where roof water goes.
The Victoria County History of Surrey, published in 1912, describes Carshalton as a village where strong springs form the larger branch of the River Wandle and the water collects in large, clear ponds. It places the parish between the downs and the London Clay, with market gardening and some lavender growing still in the landscape and a station that opened in 1868. Water is the village's signature, and it is a useful starting thought for anyone looking at a roof here, because water is also what a roof exists to move.
The same volume records older cottages built of timber, and a row of two-storey red brick cottages from the 18th century with dormer windows in their tile roofs, on the south side of the High Street east of the church. A dormer is a small window structure that stands up out of the slope with a little roof of its own. That makes extra joints: the sides of the dormer, the valleys where its roof meets the main slope, and the sealing metal that runs around them. These are the places where we start looking. A record from 1912 tells you how the street looked then, not what is on your roof today, so the survey does the real work and the photos show you each junction.
Where water gets in
Dormer sides and valleys can be finished in lead, and our lead work page explains how a worn section gets renewed without disturbing the tiles around it.
Roof water leaves through the gutters and downpipes, and a village built round springs is a good reminder that drainage deserves attention. We look at the joints, the run of each gutter towards its outlet, and whether the lowest row of tiles overhangs far enough to drop water into it. The fascia boards and soffits under the eaves come into the same check. If gutters or boards have rotted or sagged, our gutters, soffits and fascias page shows how that work runs, and we match the profile to what is on the house.
A stack that rises through the slope sits in the same water-handling group. The flashing around its base and the mortar cap on top, called the flaunching because it holds the pots in place, are the two weak points. We look at both from the ladder and check the loft for stains beneath. Our chimney repairs page explains what a repair involves.
Stage 02 · Protected places
Part of Carshalton lies in the Carshalton Village conservation area, and Historic England lists several buildings here at Grade II and Grade II*.
The national conservation area dataset shows a Carshalton Village area covering part of the settlement, with boundaries supplied by the council. Carshalton also has several listed buildings. Historic England's list records the Church of the Holy Trinity at Grade II, and 19 Park Hill, Carshalton House and the Church of All Saints at Grade II*. Your own house may be in none of these, or in more than one, and the London Borough of Sutton's planning team can say which applies. The 1912 county history adds that the parish ran from the chalk across the Woolwich and Thanet Beds onto the London Clay. Whichever part of the parish you live in, the survey reads the roof you actually have.
Putting back the same tile and the same ridge is a repair, not an alteration to how the building looks, and Section 55 of the Town and Country Planning Act leaves works that do not materially affect external appearance outside the definition of development. A new covering, a new dormer or a different ridge system alters the look, and there the council has a view. Our post on planning permission for roof work sets out where the lines fall, so read it before you settle on a design.
Terms for protected roofs
Ask the council about a listed or conservation-area roof before a date is fixed.
On a listed building, any alteration that would affect its character needs listed building consent. We therefore start with close photographs of the existing covering, the ridge, the dormer cheeks (the side walls of each dormer) and the soakers, the small lead sheets that sit under tile edges. Those pictures let the council see what is already there, and they let us price a repair that copies the existing tile, the fixings and the lead detail. Where a roof carries a lot of lead, such as around chimneys and valleys, the lead is renewed in the same pattern.
Much of this depends on what is under the tiles, so the loft visit matters as much as the climb. We look at the timber for damp and old repairs, at the underlay for tears, and at the way the roof is ventilated, and we write it up in plain English so you can show it to whoever else has a say. Keep the survey photographs with the house papers. They show a future buyer, a surveyor or the council exactly what the roof looked like and what was done to it.
Stage 03 · Permissions
Carshalton sits in the London Borough of Sutton, under the Greater London Authority, and bigger roof jobs go through the borough's own pages.
A tile-for-tile repair never meets a council form. A bigger job meets several, and it helps to know which before you commit to a date.
The Planning Portal sets the national test. An application is usually unnecessary while the work stays under 25 per cent of the total building envelope and under 50 per cent of the roof. Approval is required for a covering at least 15 per cent heavier than the existing one, or one that would fare noticeably differently in a fire. Sutton's own council pages explain how to apply for building control approval and book inspections, so on any large job we check with the building control body before we pin down a start. Loading is the thing to watch when you change material, because a different covering can weigh more than the old one, and the Planning Portal advises getting a structural engineer or surveyor to check.
Ask these first
The highway authority licenses any scaffolding that obstructs a pavement or road, while private land needs none. The scaffolder and we sort the application out together, and we confirm the notice period for your street before fixing the date, rather than guessing it. The cost sits inside the single written price, and neighbours hear about the scaffold before it goes up.
Wildlife law applies to roofs too. Bats and nesting birds are both protected, so signs of either found during the survey change the timing of the work, and we agree the new dates with you.
What decides the price on a Carshalton job comes down to the area to be covered, the covering you choose, how hard the roof is to reach and what turns up beneath the tiles once we look. The quote is one total, in writing, and you can ask us to explain any part of the work it covers. Check whether any quote you compare includes VAT and scaffolding.
Flats are a separate case. A roof over a block or a pair of maisonettes is usually shared, so the freeholder or managing agent needs to agree the work and tell the council about anything that changes its look.
Next step: tell us the road, the age of the house if you know it, and whether the roof has dormers, and we will line up a survey.
The dormer is where we spend the extra time. Its sides, its valleys and the sealing metal around it are the places water can get in, so we examine and photograph each. The county history recorded 18th-century cottages with dormers in tile roofs here in 1912, which is history, not a guide to your house: the survey tells you what yours has.
Not if it matches what is there. Part of Carshalton lies in the Carshalton Village conservation area, so some addresses fall inside it and some do not. The London Borough of Sutton's planning team can confirm yours. If it is inside, mention that when you book, and the written price will follow the tiles, ridge and details already on the roof, so nothing new appears overhead.
Work that affects a listed building's character needs listed building consent, so the council comes first. Carshalton has Grade II and Grade II* entries, including 19 Park Hill and Carshalton House. We survey, photograph the roof, price a matching repair in writing, and give you the pictures to send to the planning team for their view.
Where the frame can only go on the road or footway, the highway authority's licence is required; private land needs none. The scaffolder and we deal with it together, and we confirm the notice period before fixing your date. Neighbours are told in advance, and the access plan is agreed with you at the survey, including where materials and waste will sit each day.
Send us the road, the age of the house if you know it, and whether the roof has dormers, and we will arrange the survey.
