What national park rules, thick stone walls and moorland rain ask of a rooflight here

  • A park authority decides

    Exmoor is Article 2(3) land, so Dulverton owners confirm the rules with the park authority before they pick a design.

  • Deep roofs and half-metre walls

    Old stone gables and thick purlins mean a long shaft, so it is splayed wide and the timbers worked around.

  • Rain off the moor

    More wet weather reaches Dulverton than the lowland towns, so flashings are matched to the slate and the exposure.

  • Bats in old roofs

    Older roofs can hold protected bat roosts, so a survey looks carefully before any slate comes off.

The finishing notes

Rooflights in Dulverton

Rooflight installation in Dulverton starts with a fact that changes everything else: the town stands inside Exmoor National Park, in Somerset, so planning is decided by the Exmoor National Park Authority rather than by a district council. We are based in Exeter and cover homes up to thirty miles away, and Dulverton sits at the far edge of that, around twenty-seven miles out. We fit and replace skylights, roof windows and roof lanterns there, and we plan the visits so the journey is worth it.

The houses are mostly stone under slate, with old ceilings and deep roofs, so the inside needs as much attention as the glass. Your quote describes the room's finish in writing as well, so how the lining is shaped and how the edge ends up are agreed while the slates are still on.

01The houses

Dulverton's stone houses and the steep streets above the Barle

Stone terraces by the Barle, villas and farmhouses up the lanes, and few estates of the Exeter kind.

Dulverton is a small town on the River Barle, where the moor drops towards the river and the streets climb away from it. The centre is a tight huddle of stone buildings: shops with rooms above, terraces stepping up the slope, and larger houses set back behind walls. Local stone, often rendered or limewashed, gives the town its colour, and many buildings carry the marks of nineteenth century improvement on older cores.

Beyond the centre the housing thins out into villas, cottages and farmhouses on the lanes leading up onto the moor, with a scattering of twentieth century houses and bungalows filling gaps. Estates of the kind you find outside Exeter are rare here. Instead, most homes are individual buildings that have grown by additions, so no two roofs are quite alike.

The centre
Stone shops with rooms above, and terraces on the slope
The lanes
Villas, cottages and farmhouses
Gaps and edges

Behind the house
Lean-tos, outbuildings and kitchen extensions

That variety is the reason we survey every house in person rather than quoting from photographs.

Many of the houses were built as one thing and now serve as another: a shop turned into a home, a stable made into a studio, a barn converted for a family. Each conversion left its own mark on the roof and the ceiling, and a rooflight has to respect what is already there. Water pipes, old chimney breasts and beams that were never meant to show can all sit exactly where a window would be convenient.

That variety is the reason we survey every house in person rather than quoting from photographs. A rear lean-to, a converted outbuilding and a farmhouse kitchen extension each ask for a different product and a different lining.

02The roofs

Slate, clay tile and the occasional thatch on the Exmoor edge

Natural slate on deep timber roofs, with stone gables and old oak that a new opening has to work around.

Natural slate is the covering you expect on an Exmoor-edge house, laid on timber rafters that have often carried it for generations. Some older buildings have clay tiles or the remains of earlier thatch under a later covering, and outbuildings may carry corrugated or sheet roofing that was never meant to be seen.

Slate needs the right flashing. Thick, rough-cut slate takes a flat-roofing kit, thin and regular slate takes one made for it, and neither can be treated like a concrete tile. The old slates around a new opening are lifted and set aside by hand so the good ones go back, and any that crack are replaced with matching stock, not whatever is nearest.

GlassSplayed lining, wider at the ceiling
  • Natural slate
  • Battens and underlay
  • Old rafters, trimmed and doubled around the opening

Rooflights are also a way to improve the many rooms in the roof space of an older house that have only ever had one small window. A pair of roof windows on the rear slope, set either side of the chimney, can turn a cramped attic bedroom into a room with proper daylight from two sides, as long as the rafters and the planning position allow it.

Under the slate, the roof is often deeper than a modern one. Stone gables, thick purlins and old oak timbers all take space, and a rooflight cut into such a roof has to be fitted around them. A trimmed rafter has its cut ends supported on doubled timbers. That is structural work, so it needs Building Control sign-off, and we send the notification.

Older roofs are also where bats are most likely to roost, and they and their roosts are legally protected. If a survey shows signs of them, work stops until proper advice has been taken. It is rare, but it is a good reason to look carefully before a roof is opened.

Planning inside Exmoor National Park

Exmoor National Park Authority decides, and the conservation area and listed houses add to it.

Dulverton lies within Exmoor National Park, and the Exmoor National Park Authority is the local planning authority for the area. That has two consequences. First, a national park is what the planning rules call Article 2(3) land, where some permitted development rights for houses are restricted. Second, the authority has its own expectations about materials, proportions and the way a roof reads from a distance. Check with the authority before you assume that the rules which apply in a Devon village apply here.

The ordinary householder allowance for rooflights is still the starting point, and it carries conditions on how far the unit stands proud, how high it rises and how side-facing glass behaves, conditions that most houses can meet. Whether that right survives on your particular house depends on the house, so the authority is the place to confirm it.

What decides the route here
Planning authority
Exmoor National Park Authority
Historic centre
Conservation area, with a possible Article 4 direction
Older streets
Many listed buildings
Flats and maisonettes
Need an application

Dulverton also has a conservation area covering the historic centre, so a house in the core may face an Article 4 direction on top of the national park rules. Listed buildings are numerous in the older streets and cannot be altered on the outside without consent. Flats and maisonettes sit outside the householder allowance and need an application.

The national rules are covered in our Devon planning and Building Regulations guide. For Dulverton, treat it as the first page of the research and the authority's own planning team as the last.

04The weather

Weather on the moor edge: wet, windy and quick to change

Moor-edge rain, wind higher up the lanes and early frost shape the frame, the flashing and the glass.

Dulverton gets more rain than the lowland towns to the east, because the moor catches wet weather coming in from the Atlantic. Houses at the bottom of the valley are sheltered, while those higher up the lanes, or out towards the open ground, take wind and rain more directly. Frost arrives earlier and lingers longer.

The specification follows from that. We pick the flashing for the pitch and exposure, then check it against the slate it has to sit in. Glazing has warm-edge spacers and a good insulated frame, so the inner pane does not run cold and drip with condensation on a frosty morning. A laminated inner pane overhead is sensible in any room, and worth having where winter hail and wind-blown debris can reach the outer glass.

Specified for the moor edge
  • Flashing matched to the slate and the exposure
  • Warm-edge spacers and an insulated frame
  • Laminated inner pane overhead
  • Rain sensor on an opening rooflight

Snow and ice are part of life here too. A rooflight is not the place to save money on the flashing or the fixings, because slipping snow and refreezing meltwater test every joint. The frame is fixed to the rafters, not the battens, and the flashing is lapped under the slate above and over the slate below, so water has only one direction to go.

An opening rooflight with a rain sensor suits a house that is empty for part of the day, closing itself when a shower sweeps down the valley. An opening unit can also double as the rapid ventilation that Part F expects, which is handy in older stone houses where thick walls hold damp air for days.

Next note: Which rooflight for which Dulverton roof

05The right product

Which rooflight for which Dulverton roof

A conservation rooflight for a listed house, a roof window in a loft room, a lantern on the kitchen extension.

With so many individual buildings, the product depends on the house, the slope and the consent position:

House or roomProduct that suits
Listed and conservation area housesA slim-framed conservation rooflight close to the slates, on the least visible slope
Cottages and farmhouses where the roof space is a bedroomA roof window, centre-pivot or top-hung to suit how the room is used
Kitchen and barn extensionsA roof lantern over a flat roof, lined inside so the kerb reads as part of the ceiling
Dark landings and bathrooms in thick-walled housesA sun tunnel, since it takes only a small opening through the roof

Listed or conservation area house

Usual product
Slim conservation rooflight on the least visible slope
Consent
Listed building consent, and the park authority
Roof covering
Natural slate
Lining finish
Lime plaster

Cottage or farmhouse extension

Usual product
Roof window, or a lantern on a flat roof
Consent
Check with the park authority
Roof covering
Slate or flat roofing
Lining finish
Boarded and taped, or plastered

Glazing is chosen room by room. A south-facing bedroom may take solar control glass, while a shaded kitchen on the valley floor wants clear, high-performance glazing at the biggest size the opening allows. Any new or replacement rooflight has to satisfy the heat-loss limits of Part L.

Walk-on glass and flat rooflights have their place too, and they are worth raising early because their specification differs from a pitched unit, particularly on stone outbuildings turned into studios, where a flat roof sits behind a parapet and a flat rooflight can be almost invisible from the lane. We fit these with an upstand and a lined kerb, and with the glass specified to suit what people will do on or beneath it.

If you already have an old rooflight with a misted unit, replacing an old skylight is the page that explains when the sealed unit alone can be changed and when the whole window must be replaced and notified.

06The ceiling

Thick walls, old ceilings and what sits behind the plaster

Half-metre walls and lath ceilings turn the shaft into a tunnel, unless the lining is splayed and made good to match.

Inside a Dulverton stone house, the walls are often half a metre thick, the ceilings are lath and plaster in the older rooms, and beams may cross at heights the builders never planned. A rooflight shaft through that depth can be a tunnel, and a straight tunnel looks like one.

So the lining is usually splayed. Widening the opening toward the ceiling spreads daylight through the room and lets the shaft look like part of the architecture. The idea is explained in what a splayed rooflight lining is. The shaft is formed in timber and board or plastered in lime, depending on what the room around it is made of.

  1. Support the ceilingPropped from below
  2. Score and cutLaths trimmed back to the nearest timber
  3. Form the shaftSplayed toward the ceiling
  4. Finish to matchLime, or taped board

Old ceilings are opened with care. We support them from below, score before cutting and trim the laths back to a timber, which fixes each end. In houses that have been limewashed and lime-plastered, we use lime at the join, because modern gypsum tends to crack away from it. Where the room has been replastered in modern materials, a taped or skimmed board lining matches it.

Every one of these choices is written into your finish schedule, including whether the lining reaches you primed or fully painted.

Next note: A Dulverton survey, up the Exe valley

07The survey

A Dulverton survey, up the Exe valley

We drive up the Exe valley, survey the roof, room and access, then send the quote in writing.

The drive from Exeter runs up the Exe valley through Tiverton and Bampton, both of which we also cover, so a Dulverton survey is often planned alongside work nearby. We begin outside, studying the roof, and then climb up through the loft before standing in the room to take the depth from roof to ceiling, identify the ceiling material and spot anything that will show in the finished opening.

The survey also tests access. Dulverton's streets are steep and narrow in places, and anything standing on the public highway, a tower or scaffold included, needs a licence from Somerset Council as highway authority, so we leave room in the programme. For a park or listed property, the same visit gathers what an application to the authority will need.

What the survey records
Roof covering
Slate, tile or flat roofing
Roof to ceiling depth
Measured in the loft
Ceiling material
Lath and lime, or plasterboard
Access
Steep streets, tower or scaffold, any licence

Because the round trip is long, we tell you the price in writing before any date is booked, and the work waits for your agreement. Stone houses throw up a lot of fine dust, so the room is sheeted off and left clean, and ten years of workmanship cover applies. If you would like us to come out, the quote form is quickest, and a WhatsApp reaches us just as well. Our address is info@brightviewskylightsexeter.co.uk.
