Skylights and rooflights in Resolven

Resolven, Resolfen in Welsh, is a small village and community in the county borough of Neath Port Talbot. Some of what it has is made of water and iron. The Neath and Tennant Canal has been restored and now has over four miles of walkable towpath between Resolven and Glynneath. The Vale of Neath Railway is still used for freight between Neath and Cwmgwrach.

Other things are about people and buildings. Sir Clifford Darby, the geographer, was born in Resolven, and he lived from 1909 to 1992. Debbie Llewellyn, originally from Resolven, served as Mayor of Gloucester for 2014–15. Rheola House has a plan attached to it: the vacated site has plans to restore the house and its estate buildings and to establish leisure and tourism facilities.

Resolven is north-east of Swansea, and the 14.92-mile road distance keeps it inside our 30-mile area. Neighbouring villages we cover include Cwmgwrach, Crynant, Glyncorrwg and Seven Sisters.

On the houses themselves, only the general picture can be offered. Older terraces and cottages usually have pitched roofs with a back slope where a single window fits. Houses from the post-war years tend to leave more width. Flat roofs appear where a kitchen has been added at the back, and that is where a lantern or a low rooflight earns its place.

Which description matches your house is easier to see from the street than from a distance. The survey puts it right, and nothing is quoted until it has happened. If you already have a rooflight and it misbehaves, describe what it does: drips, clouds over, pools water or sticks. The symptom usually narrows the cause before anyone climbs a ladder.

Water and iron frame the village on two sides. Walkers can follow the restored Neath and Tennant Canal towpath for more than four miles towards Glynneath, while freight trains still run on the Vale of Neath line between Neath and Cwmgwrach.

For a rooflight, the useful early question about any house is the shape of its roof and the use of the room beneath it. A pitched slope suits a window set flush with the slates or tiles. Over a flat roof the choice is a rooflight with its kerb, or a lantern with its upstand. A dark inner room with a loft above is the case for a tunnel. The same house can end up with all three, in different rooms, chosen one at a time.

Neath Port Talbot Council handles planning for a Resolven house, and the Gower AONB lies elsewhere. The answer to whether you need an application turns on the house and its history, and the Welsh skylight planning page is the place to read it.

Four kinds of house are treated differently. Householder rights never covered flats or maisonettes. A council direction under Article 4 can remove the rights from a house. Planning conditions from an earlier consent can have done the same. A listed house needs listed building consent for a rooflight that touches its character, and Cadw supplies the guidance behind that.

A lantern deserves its own note. Fitted over an existing flat kitchen or garage roof, a lantern normally calls for a planning application, because it usually rises well above the roof. A lantern designed into an extension that does not exist yet is another matter, and that question goes to the council at survey, since no general rule settles it.

Building Regulations are the second track. A new rooflight needs approval in the normal run of things, and the Welsh Government's pages on roof lights give three reasons: the alteration to the roof, the weight of the unit and its energy performance. You can use Neath Port Talbot's building control team or a registered building control approver. Notifiable work is notified by us.

Energy limits apply to new and replacement units. A roof window should reach 1.4 W/m²K or Window Energy Rating Band B, and a rooflight 2.2 W/m²K, under Approved Document L (Wales). Safety glazing is covered by Approved Document N. A replacement window should leave the home's ventilation no worse, which is Approved Document F, so vents on the old window are matched on its successor.

Doubt about any of this has a cure. Ask the council's planners for their view; a Lawful Development Certificate then records it formally. That paper is useful again when the house is sold.

A kitchen extension is the room most likely to want a lantern, because the roof is already flat and the room wants plenty of light. Over a worktop, a roof lantern throws daylight down from above and carries it well past the back door. Over the same hole a flat roof rooflight gives a sleeker line from outside and a lower profile, and a different relationship with the weather.

Upstairs and in the middle of the house, the question is darkness. A landing in a terrace can have no outside wall at all. A sun tunnel picks up light on its small roof dome and sends it through the tube to the ceiling. On a drizzly morning it lights the top of the stairs without a switch being touched.

Bedrooms under the slope are the place for a roof window. A top-hung sash opens above head height, and a centre-pivot turns for cleaning. On VELUX solar and electric windows a built-in sensor shuts the sash when rain starts, a sensible choice for a room you leave aired. More are on the electric opening rooflights page.

Old units give another reason to ring. A rooflight that has fogged between its panes has a failed sealed glass, and replacing misted rooflights is work we do, along with new fittings. If only the glass is swapped in a frame you keep, the energy rules do not count it as building work, whereas a whole new window is covered.

Cleaning and reach come into every choice. A window in a steep slope is awkward from outside but easy from within if it pivots. A lantern high above a kitchen is out of reach for a cloth. A tunnel's dome is small enough to ignore. Thinking about how the glass will be kept clear before it is bought saves a lot of ladder work later.
