Cob walls and deep barn roofs in Crediton, and what they demand

  • Lath, lime and cob

    Behind the Georgian fronts the ceilings and walls may be lime, so the lining plaster has to be compatible or the join cracks.

  • Deep barn roofs

    A converted farm building has a long shaft from glass to ceiling, so a wider, angled lining is what carries daylight down into the room.

  • Mid Devon's rules

    The protected centre has listed buildings, and barn conversions can carry conditions on their permission.

  • Yards and farm tracks

    Access runs from passages off the High Street to narrow lanes, and the survey settles where materials are unloaded and any scaffold stands.

The finishing notes

Rooflights in Crediton

Our work in Crediton ranges from new skylights and roof windows to lanterns and like-for-like replacements, from the Georgian shopfronts of the High Street to the barn conversions out along the Creedy valley. The town sits about nine miles north west of Exeter, and Mid Devon District Council, not Exeter City Council, deals with its planning. That matters for anyone near the centre, where part of the town is a conservation area.

The houses here are mixed and the ceilings are mixed with them: lath and plaster, cob walls under thatch or slate, plasterboard in the newer streets. Each quote sets out in writing what happens inside the room, so how the opening is lined, plastered and left is settled long before anyone climbs onto the roof.

01The houses

Crediton's streets: rebuilt Georgian, cob lanes and Victorian terraces

Georgian rebuilding on the High Street, cob in the lanes, Victorian terraces and barn conversions beyond.

Crediton is an old town with a short memory for its own buildings, because fire took much of it in the eighteenth century. The High Street and the streets close by were largely rebuilt afterwards, which is why so much of the centre reads as Georgian: flat-fronted brick and render, sash windows, narrow plots running back to yards and gardens. Behind those fronts, and in the lanes that run off them, older cottages survive, built of cob or local stone and rendered over.

Victorian growth added terraces and villas on the rising ground around the centre, many of them in brick or stone under slate, with the tall ceilings that loft conversions like to borrow height from. Beyond them the town thins into twentieth century housing: interwar and postwar semis, bungalows on cul-de-sacs, and newer estates built to the north and east.

Skylight installation in Crediton therefore starts with a plain question: which of these houses is yours? A Georgian terrace on the High Street, a cob cottage in a lane and a 1990s semi on the edge of town can sit within a few minutes' walk of each other, and each needs a different opening, lining and plaster.

Past the edge of town the picture shifts again. Farmsteads around Crediton have been turned into homes, with cob or stone walls, big timber roofs and glazing openings that the original builders never planned. A rooflight in one of those is closer to a design decision than a standard fitting.

02The roofs

Slate, tile and the deep roofs of Crediton homes

Settled slate roofs, deep barn timbers, regular trusses on the newer streets.

Natural slate covers most of the older Crediton roofs, with some clay tile and the odd thatched cottage on the outskirts. Slate roofs from the Georgian and Victorian rebuilding sit on softwood rafters that have settled with age. Spacing is seldom even, and a roof window that drops neatly between two modern rafters may need one trimmed on an older roof, with the cut ends supported by paired timbers. That changes the structure, so approval from Building Control is needed, and the paperwork goes in from us.

Barn roofs are different again. The timbers are large, the span is long, and the roof build from slate outside to plaster or board inside can be much deeper than on a house. A deep build means a long lining shaft, and a long shaft is where a splayed reveal does its best work: widened towards the room, it spreads daylight across the ceiling and stops the opening looking like a tunnel.

GlassSplayed lining, wider at the ceiling
  • Natural slate
  • Battens and breathable underlay
  • Large timber rafters, cut and trimmed to frame the opening
  • Insulation between and below
  • Plaster or board ceiling

The newer streets are easier going. Trussed rafters under concrete interlocking tile are typical, with regular spacing that ready-made flashing sets are designed for. Rear extensions and garage conversions mostly have flat roofs covered in felt, GRP or EPDM, where a lantern or low flat glazing on a raised upstand fits best.

Thatch needs a plain word of caution. Cutting an opening in a thatched roof is a specialist call, and a thatcher has to be involved. We will tell you at the survey if the roof is not a job for a standard rooflight, and what the alternatives are, including a sun tunnel or a rooflight set into an extension roof instead.

03Planning

Crediton's protected streets and what Mid Devon decides

Mid Devon is the planning authority; the old centre lies within a conservation area, and a listed house needs consent.

Planning for Crediton is handled by Mid Devon District Council. On most houses a rooflight can go in under the general permitted-development limits, which cover how far a unit may stand off the roof, how high it may rise and how side-facing glass is treated. Those limits are explained in our Devon planning and building control guide, so this section sticks to what is particular to Crediton.

Much of Crediton's old centre has been designated a conservation area. Inside the conservation area the normal right generally holds, yet a council can remove it by direction, so ask Mid Devon whether that has happened on your street before settling on a design. Many buildings around the parish church and along the main streets are also listed, and a listed house needs consent for changes to the outside, a rooflight included, and for work touching the old fabric within.

Planning checks for a Crediton house
  • Which council decides: Mid Devon District Council
  • Is the house in the conservation area
  • Has an Article 4 direction removed the usual right
  • Is it listed, so consent is needed
  • Is it a flat or a barn conversion with rights removed

Flats and maisonettes, including those above High Street shops, have no householder rights, so putting a rooflight on one means applying for planning permission. Barn conversions can carry their own conditions, because the conversion permission sometimes removes those rights altogether, so check the decision notice before you plan anything.

04The valley

Weather in the Creedy valley and on the hills above Crediton

Sheltered in the Creedy valley, but rain comes up on a westerly and cool air settles at night.

Crediton lies in the valley of the River Creedy, with higher ground rising around it. The valley shelters the centre from the worst of the wind, but it is not a coastal town and it is not immune. Rain comes up the valley on a westerly, and homes on the hills at the town's edge catch it more directly than those in the streets below.

The same valley holds damp, cool air on still nights. Condensation shows first on cold surfaces, and an under-insulated rooflight lining is one of them, so the quality of the insulation behind the lining and the seal between frame and vapour control layer matter as much as the glass. Where a farmhouse or barn has a high exposed roof, we also choose the flashing to suit the pitch and how exposed the roof is, rather than taking the standard kit off the shelf.

Specified for the valley
  • Flashing matched to the pitch and exposure
  • Insulation behind the whole lining
  • Vapour control layer sealed to the frame
  • Opening unit high in the slope
  • Rain sensor on electric units

Wind-driven rain is a flashing question, and the valley's damp is a lining question. Between them, the survey settles the insulation thickness, the flashing kit and the order in which the work is done, so the roof is closed and weathered the same day it is opened.

Summer is the other half. Top floors under slate warm up, and a loft bedroom can hold heat well into the evening. A rooflight that opens, set high in the slope, lets the hot air escape, and a motorised one with a rain sensor can stay ajar on a changeable day.

05The right product

Matching glass to Crediton's cob, slate and new brick

Conservation rooflights in the centre, lanterns on barn conversions, roof windows for lofts.

Product choice follows the roof and the room, and the planning position decides the rest.

For listed and period houses in the centre, a conservation rooflight on the back slope is the natural fit, set low to the slates with slim frames. A Victorian terrace with a loft room can usually take a roof window in the rear pitch, provided no Article 4 direction stands in the way.

Barn conversions and large kitchens call for a roof lantern or a flat unit on a kerb, with the lining formed to suit the deep roof build. Newer estate homes do well with a standard roof window in double or triple glazing, laminated on the inner pane, or a sun tunnel to bring light to a gloomy landing or bathroom.

Glazing follows the room. A north-facing landing does best with clear, high-performance double glazing in the largest frame the roof allows, so the daylight reaches the stairs below. A south-facing loft bedroom is better with solar control glass or an opening unit, because heat gathers under a slate roof by late afternoon. In a kitchen extension the lantern is chosen for proportion as much as performance: a glazing bar pattern and a cill height that suit the room rather than a standard catalogue size.

A laminated layer on the room side of the glass is a prudent choice, not a Building Regulations rule, and the small extra cost is justified in a bedroom or over a stair. Part F ventilation can also draw on an opening unit.

A fresh opening in an existing roof counts as building work, and so does exchanging a complete unit, frame and glazing together. Both must reach the Part L heat-loss standard, and the council's building control team is told by us. A sealed glass unit changed alone in a sound frame needs no notification.

06The ceiling

Cob, lime and lath: finishing the ceiling inside a Crediton home

Lath, lime, cob and plasterboard each want a different method, and the shape of the lining matters as much.

This is the part you will look at every day, and in Crediton it is rarely straightforward. Behind the Georgian fronts, ceilings are often lath and plaster, sometimes lime, sometimes a later gypsum skim over the top. Cob cottages have thick walls, uneven rafters and lime plaster that is meant to breathe. In the newer houses it is plasterboard, taped and skimmed.

The method changes with the ceiling. In a lath and plaster room we prop the ceiling from below before any cutting, score the plaster cleanly, and secure the loose areas around the opening. In a cob house we keep the lining and its plaster compatible with the lime around it, because a hard gypsum edge pressed against soft lime plaster cracks at the join as the two move differently. In a plasterboard room, the lining is boarded, taped and skimmed so it blends into the surrounding ceiling.

  1. Prop and protectSupport the ceiling, cover the room
  2. Cut cleanlyScore the plaster, cut to a timber
  3. Form the liningLining opened out where the roof is thick
  4. Match the finishLime, or boarded and skimmed

Old houses also reward patience over speed. A lime edge is built up in coats, and each has to take before the next goes on. We would rather programme the work so the lining has time to set properly than rush a hard finish that shows a hairline crack by Christmas. Your finish schedule says which approach applies to your ceiling and how many visits the plaster needs.

The shape matters as much as the material. Where the roof is deep, the lining is splayed so the opening grows towards the room. A straight-sided shaft through a barn roof wastes most of the light the glass collects and looks like a hatch from below.

Each of these decisions is recorded in the finish schedule issued with your quote, covering what the roof and ceiling are built from, the lining's shape, its surface and whether it is left primed or painted. The sequence is described in our walk-through of indoor finishing.

07The survey

Crediton survey day: roof, loft and the way in

The survey covers roof, room and loft, access across yards and farm tracks is sorted, and the quote is put in writing.

The Creedy valley road makes Crediton a short drive from Exeter, so arranging a visit is easy. We start by studying the roof from outside, then move into the room and loft, take the depth between roof and ceiling, test what the ceiling is made from and whether it is sound, and write down anything that will shape the finish, for example a cornice or a hairline crack running towards where the opening will go.

Access is part of the survey. Some High Street properties have yards reached through passages, and others have no off-street space for a delivery. Out in the countryside a farm track may be too narrow for a lorry. The visit settles where deliveries can be dropped, if a tower or scaffold is required and if a highway licence is part of the picture. On a listed or conservation area job it also gathers what is needed to support the application.

The price comes in writing once we have seen it all, with the finish for your ceiling agreed before the first fixing. Floors and furniture are protected, the room is cleared of dust at the end, and our 10-year workmanship guarantee applies. Whether it is a High Street flat, a cob cottage in a lane or a farm conversion, the quote form is the simplest start, and anything sent over WhatsApp or by email to info@brightviewskylightsexeter.co.uk is read the same way. If a neighbour or relative lives elsewhere, we also cover Bow and Tiverton, and the whole range is on the homepage and the areas page.
