Rooflights and skylights in Rudgwick, round the conservation area and the old farmhouses

Rudgwick is a village and civil parish in Horsham District, West Sussex. It is 15.3 road miles from Crawley, so a survey here is a planned visit rather than a quick call in, and we arrange it that way.

The 2011 count recorded 2,722 residents, down from 2,791 at the 2001 census, spread across 24.69 square kilometres. That is a lot of ground for a small population. It tells you the parish is mostly open, with the houses of the village gathered in one place and the rest set well apart along the lanes. A rooflight here is rarely one of a dozen identical openings on a terrace. It is usually one opening on one particular roof, and it gets designed as such.

The A281 ties Rudgwick to Horsham in one direction and to the Surrey border in the other. The sound we talk about in Rudgwick is the ordinary sound of weather on glass, and the stillness of a village at night, which makes small noises easier to hear. More on that below.

Several 17th and 18th century farmhouses in the parish are listed Grade II or Grade II*. A listed building has its own consent route, separate from ordinary planning permission, and a rooflight in a listed roof is a matter for listed building consent.

That shapes how we approach a farmhouse, or a converted outbuilding that belongs to one. The survey is slower. We look at how the roof is framed, which slope is least visible, and whether a conservation-style unit sitting low against the covering could do the job. Our conservation rooflight installation service is built around that kind of fitting: a slim frame, a flush or near-flush profile and glazing set to the light the room needs, without turning the slope into a display.

A few practical points follow from age alone:

• Rafters in older roofs are seldom at a regular spacing, so the opening is sized to the timbers the survey finds, not to a catalogue width.
• Old timber is worth keeping. Where a rafter has to be trimmed for an opening, the load is carried by a properly sized trimmer, and that detail is agreed before work starts.
• A roof that has moved over the centuries may not be square. The flashing and the upstand are dressed to the roof as it is.

A village away from main routes is a quiet place, and that changes what you hear indoors. When there is no traffic hum in the background, a hard shower on a flat rooflight is the loudest thing in the room. Rain drumming on glass is physics, not bad luck: a flat, stiff pane over a hollow space makes a good drum.

Quiet in a rooflight is a matter of specification, and there are a handful of choices that work together:

1. A laminated acoustic inner pane, which damps vibration that a plain pane would pass straight into the room.
2. Panes of different thickness in the sealed unit, so the two sheets do not ring together.
3. Good compressed seals all round, so the unit sits in its frame without a gap to whistle through.
4. An insulated, lined upstand, which stops the kerb itself acting as a sounding board.

A rooflight changes the thermal element of a roof, so the work has to meet current Building Regulations. We install to current Building Regulations, and we handle the Building Control notification where the work is notifiable.

Four parts of the Approved Documents do most of the work on a rooflight:

• Part L governs energy, so the glazing and the upstand insulation are chosen to meet the current standard for replacement and new elements.
• Part K covers protection from falling, so a rooflight near a floor edge or a walkable roof needs the right guarding or glass.
• Part B applies where fire spread matters, which can limit rooflights close to a boundary.
• Part F deals with ventilation, and an opening rooflight can help with purge ventilation in a loft room or a kitchen.

A survey is a visit to the room, and it comes before any price. We look at the roof from outside and from inside, identify the covering, measure the opening, examine the structure behind, and check the address against the council's planning information. You get an honest account of what the roof will take.

The steps run in a set order:

1. You send a message through the quote form or by WhatsApp with the address and the room you have in mind.
2. We check the planning position for the address: conservation area, listing, or neither.
3. We visit, listen to the room on the day, and take measurements from inside the roof space.
4. The quote arrives in writing with the quiet spec for the room attached.
5. On acceptance we book the work, and the 10-year workmanship guarantee covers it once complete.

These are the questions to settle when a rooflight is being planned for a village house with a little history attached.
