Rooflight and skylight installation in Kelvedon
A long village street on the old Roman road, with a conservation core and commuter housing.
Rooflights we install in Kelvedon
Every job is surveyed first. The right unit depends on the roof you have, not on what we would rather sell.

Kelvedon runs along the old Roman road between Colchester and Chelmsford, a long village street with a conservation area and substantial commuter housing behind it.
The street
Period buildings, many listed, fronting directly onto the road. Front slopes are highly visible and effectively out of bounds for anything other than a flush conservation unit, and often out of bounds entirely.
Rear slopes are a much easier conversation, and that is where nearly all successful work sits.
Behind the street
Twentieth century and modern housing, trussed roofs, profiled tiles, and generous plots. Rear extensions with flat roof rooflights are the standard job, and the plots support wide extensions which makes lanterns practical.
Skylight and rooflight work we cover in Kelvedon
Roof lanterns, flat roof rooflights, roof windows, VELUX replacements, conservation units and sun tunnels, all surveyed before they are quoted. We also work in Feering, Coggeshall and Witham.
A village strung along a Roman road
Kelvedon runs along a single long High Street on the line of the old road, with the Blackwater below it and twentieth century development spreading behind. The street carries a conservation area and a substantial run of listed buildings, many of them timber framed behind Georgian and Victorian frontages.
That shape has a practical consequence: almost every historic property here is a narrow plot running back from a street frontage, which decides both the constraint and the access.
The High Street properties
Steep pitches, cut roofs with rafters and purlins, clay plain tile and slate, and frequently older fabric behind a later face.
Where a building is listed, listed building consent is required for a rooflight on any slope, front or rear, whether or not anybody can see it. The listing covers the whole building inside and out. There is no small works exception and no rear elevation exception.
Where it is unlisted but in the conservation area, permitted development for rooflights on a house survives unless an Article 4 direction removes it. On a long street frontage of this quality a direction is entirely plausible, and it is a short enquiry to the council rather than a judgement call.
Where consent is needed, a conservation rooflight is what gets approved: low profile so it sits close to the plane of the covering, upright rather than wide, central glazing bar, matt black. The profile matters more than the other characteristics combined, and the manufacturer’s section drawing showing how far the unit stands proud is the document that answers the officer’s real question.
On a rear slope, running back from the street and screened by the ridge, the case is considerably easier and a standard unit may well be acceptable. Worth asking rather than assuming the expensive product is compulsory.
Timber framed structures
Common here behind later frontages, and it changes the fundamentals.
The frame is frequently part of what is listed, so an opening is positioned to avoid historic rafters and purlins rather than cut through them. The survey establishes where a rooflight can go before anybody discusses what it should be, and made to measure sizes are often the answer.
These buildings also move seasonally, so fixing has to allow for it rather than clamp the unit rigidly into a frame that flexes.
And expect no underlay on a roof that has never been stripped. Modern weathering assumes a membrane to lap into; where there is none the detail is built around the opening instead. Normal, more work, and it belongs in the quotation rather than in a conversation on the day.
The twentieth century housing
Behind the street the work is ordinary and much easier. Concrete interlocking tiles, pitches around 30 to 35 degrees, cut roofs on the earlier properties and trussed rafters on the later ones, off street parking and space to stand a tower.
Establish cut or trussed from a loft photograph before anything else, because it decides more about the price than the choice of unit does. Rafters with a purlin and clear space between means a wide opening is ordinary carpentry. Triangular frames with diagonal webs joined by flat pressed steel plates means opening width is limited to the 600mm truss spacing unless a designed trimmer is installed.
Profiled interlocking tiles need a deep flashing kit rather than the flat kit used on slate, and it is worth confirming by name on any quotation, because a flat kit leaves voids under the tile channels that water finds within a season.
Access on the high street
The main practical constraint. Frontages sit on or close to the pavement, parking is limited, the road is busy, and side access to the rear varies from a full driveway to nothing at all.
Where scaffold has to stand on the highway a licence is required from the county council and it takes time to arrange. Where there is no side access, scaffold and materials sometimes come through the house, which is normal and needs planning at survey rather than improvising.
Tell us at the enquiry stage whether there is side access to the rear. On a Kelvedon High Street property that single fact changes the shape of the quotation more than the choice of unit does.
What we fit here
Conservation rooflights on the historic frontages where consent requires them, standard roof windows on rear slopes and on the later housing, flat roof rooflights and lanterns over rear extensions, sun tunnels into internal bathrooms in the narrow plan cottages, and a steady amount of replacement work as units from the 1980s and 1990s reach the end of their sealed unit life.

Replacement work along the street and behind it
A growing share of what we do here is replacing units that have failed rather than forming new openings. Sealed units last fifteen to twenty five years and a great many went into this village during the 1980s and 1990s.
Start with the data plate rather than a tape measure. It is on the top edge of the sash or on the frame beside the hinge, and on a centre pivot window rotating the sash brings it into easy view. Photograph it rather than typing it out, because the characters are small, several are easily confused, and a mistyped code buys the wrong window.
From that photograph we can usually tell you what it is, whether the size is still made, what the options are if not, and a realistic price, without anyone visiting.
Obsolete sizes
Normal for anything of that age and entirely solvable. Three routes.
Adapt the opening to the nearest current size, usually within 40mm or 60mm, packing out or trimming back then making good the reveal. Invisible when finished and it leaves a standard size for the next thirty years. This is the usual answer.
Find another manufacturer at the old dimension, which suits an opening that is genuinely awkward to alter.
Reframe to a current size, which makes sense where several windows are being standardised or the timber needs replacing anyway.
What nobody should do is force a unit into an opening it does not fit and pack the difference. It survives about a year before the packing settles, the frame goes out of square and the sash stops closing properly.
The glass upgrade you get anyway
A unit fitted twenty five years ago has no low emissivity coating, no argon, an aluminium spacer and no solar control. The replacement has all four as standard, so the room will be warmer in winter, cooler in summer and quieter in rain without paying extra for any of it.
Where the window faces south or west, adding solar control glass at this point costs a modest premium because the labour and access are already being paid for. Coming back for the glass alone later costs nearly as much as the whole replacement.
Doing several at once
The reliable saving, and it matters most where access is expensive. On a High Street property needing pavement scaffold and a highway licence, two units done together cost far less than two done a year apart.
Since units fitted at the same time fail at about the same time, the second replacement is usually coming whether it is planned or not. If two of three have misted, ask what the third costs while the scaffold is up.
Sun tunnels in the narrow plots
The long thin plots running back from the street leave a good number of internal bathrooms, WCs and hallways with no external wall and no available slope. There is no rooflight answer for a room like that, but there is a tunnel answer wherever there is a loft above.
A rigid mirrored tube brings genuine daylight down into a room that has never had any, for a fraction of the cost of anything else, and the roof component is small and low enough that on a rear slope it is effectively invisible from the street, which matters in a conservation area.
Specify rigid rather than flexible: a flexible foil tube scatters light at every fold and delivers roughly a third of what a rigid tube of the same diameter gives. Size by diameter, since output goes with area, so 350mm passes about twice the light of 250mm. And insulate the tube where it crosses the cold loft while sealing the ceiling ring airtight, or condensation forms inside it and arrives at the diffuser looking exactly like a leak.
It is not a rooflight: no view, no ventilation, no sense of sky, nothing after dusk. Most units take an optional light fitting inside the diffuser so the same ceiling opening does both jobs. On a listed building it still needs consent, because it is not exempt for being small.
Timescales
A like for like replacement into a sound opening is a single day. A new opening in a tiled roof with making good runs to three or four days. A sun tunnel is usually half a day.
Along the High Street, consent is frequently the long part rather than the fitting. A listed building consent application runs to months, and a conservation rooflight in a non standard size adds several weeks on top. Start the application first, order the unit second, and book the fitting to the delivery date.
Access adds its own step where scaffold has to stand on the highway, because a licence takes time to arrange. Behind the street, on the twentieth century housing, none of that applies and the programme is short.
What to send us
A photograph of the roof, one of the frontage showing the street, and the address so we can check the listing and Article 4 position ourselves.
Tell us whether there is side access to the rear. On a High Street property with a long narrow plot behind it, that single fact changes the shape of the quotation more than the choice of unit does.
If the building is timber framed behind a later frontage, say so, and if you can safely photograph the roof structure from inside, that is genuinely useful. Where historic rafters and purlins constrain the position, the survey establishes what is possible before anyone discusses the product.
For a replacement, photograph the data plate on the sash rather than measuring.
Asked by people in Kelvedon
Is the long village street protected?
There is a conservation area over the historic street, with substantial commuter housing behind it that generally is not. Kelvedon runs along the old Roman road, so frontage properties are prominent by definition.
What is achievable on the street?
Rear slopes with a low profile conservation unit, submitted with the section drawing. A front-facing unit on the historic street is unlikely, and worth testing in a pre-application conversation before any design work.
Is the commuter housing straightforward?
Yes. Trussed rafters, concrete tile, no designation, and a unit between two trusses with no structural design needed.
Do you cover Feering as well?
Yes, Feering sits across the Blackwater from Kelvedon and both are within our patch, along with Coggeshall and Witham nearby.
