Skylights & rooflights in Mayfield

Some Mayfield roofs already carry a window or rooflight fitted years ago. Sooner or later these start to show their age, and it helps to know what you are looking at.

The commonest sign is a misty film inside the glass that will not wipe away. That tells you the seal around the double-glazed unit has failed and moist air has got between the panes. Moisture in a sealed unit does not leave again, so the answer is assessment and replacement. The signs to look for are laid out on our misted and failed rooflights page.

Other signs point to the frame or the flashing rather than the glass. A brown tide mark on the plaster beside the window, a timber frame that has gone soft, or a sash that sticks and no longer shuts evenly all mean the unit is due for a closer look. Sometimes the cause is the flashing around the opening, which can lift or crack over time. When we assess the unit we look at the whole assembly, because replacing the glass without dealing with a worn surround would only postpone the next problem.

A second clue is how the unit behaves in weather. A window that is dry in summer but drips on cold mornings is telling you that warm, damp air from the room is meeting a cold surface. That points to poor thermal performance in the frame or glass. A window that leaks only in driving rain points to the flashing or the seal between frame and roof covering. Telling these apart is part of the survey, and it saves you paying for the wrong fix.

Timber, metal and plastic frames

Older units come in different frame materials. Timber frames were common and can last a long time if kept painted, but they rot once water gets in. Metal frames can corrode at the joints. Early plastic frames can warp. Each tells its own story when we inspect it, and the material helps us judge how long the unit has been up there and what lies beneath it.

Windows installed to an older standard also tend to leak heat. A replacement unit meets today's thermal standards, and the difference is usually noticeable in a cold attic room. That is worth keeping in mind when you ask for a quote.

1. Look at the glass Check for haze, droplets or a mark that shifts with the weather.
2. Check the frame Press the timber near the bottom corners, and look for opened joints.
3. Check the ceiling Stains on the lining beside the window point to the surround.
4. Photograph it Take a picture from inside and, if safe, from the garden.
5. Book a survey We assess the unit and write down the fixed price for replacing it.

Many of the fine houses in Mayfield date from the sixteenth and seventeenth centuries, when the Wealden iron industry was at its height. Houses of that age have roofs built by hand, and they behave differently from modern roofs.

The timbers are often large, irregular and set at spacings no modern catalogue would predict. The roof may sit on a frame that has settled and moved over centuries, so lines that look straight are not. A rooflight cut into this kind of roof needs measuring in place. We do not work from a standard drawing, and we do not assume the rafters sit where a modern house would put them.

Cutting an old rafter is a structural act. If an opening needs a rafter removed, a trimmer has to be added on each side to carry the load, and the neighbouring timbers must take it without sagging. We agree the structural method before any cutting and tell you if a specialist's drawing is needed.

Because the roof is old, the loft space often holds clues about its history. Smoke-blackened rafters, pegged joints and later additions can all be seen from inside. We photograph the roof structure before we start so you have a record of how it looked, and so that any decision about where to place the opening is based on what is actually there.

Respecting the fabric

Old houses reward a careful approach. Original timbers, lime plaster ceilings and early tile hangings are part of the building's value. Where possible, we place an opening so that it avoids important timbers and works with the existing structure. Interior linings are made good around the new frame, and we talk through what the finished reveal will look like before work begins.

Where an old roof is steeply pitched, that suits roof windows well, because a steep pitch lets in light at a good angle. The page on roof windows covers the options, and for sensitive roofs the conservation rooflights page describes units made to sit flush with the tiles.

Part of Mayfield lies inside the Mayfield and Coggins Mill conservation area, designated in March 2017. Wealden District Council is the planning authority. A conservation area alone is not the whole story, and the part that is hard to pin down is whether a direction applies to your address. Wealden's own published information on directions is not consistent, so we do not tell customers there is or is not one. Ask the council, in writing, about your property.

Houses of the age found here may also be listed. A listed building has a separate layer of consent, and the council can tell you whether yours is on the list. Our planning guide explains how to ask the right questions and what to keep on file.

A conservation area is about appearance from the street and the setting of old buildings. For rooflights that usually means keeping the opening modest, setting it flush with the tiles and, where possible, placing it on a slope that is not seen from the road. We talk through placement with you, because a position at the back of the house often avoids the question altogether.

Wealden leads the East Sussex Building Control Partnership, and that is the service covering Mayfield. Our Building Regulations guide sets out what it covers.

Steep pitches call for a full scaffold with boarded lifts, not a ladder. Working at height on a steep, uneven roof surface is no place for shortcuts, and the structure also needs protecting. Old tiles are brittle, and walking on them breaks them. We use crawling boards and lay out the working area so that we disturb as few tiles as we can.

Weather also decides the programme. Work on a steep, exposed roof waits for a dry, calm spell. Each opening is made weathertight the day it is cut, so you do not have a hole in the roof overnight, and the plan tells you what happens if the forecast turns.

If you rent or lease part of a building, the roof may not be yours to alter, and the neighbours may share the structure. Our page on flats and leasehold buildings explains who has to agree. We include the notice to neighbours in the plan.

A rooflight is a fixed part of the house for decades, so the choice deserves thought. We would rather spend an extra half hour at the survey talking through the options than have you live with a window in the wrong place.

With the roof understood, the choice of unit follows from the house and the room.

A steeply pitched attic or loft room takes a roof window, set between rafters at a height where you can see out. Where the pitch is low or the roof is an extension, a flat-roof unit does the job, and the flat roof rooflights page shows the options. If you want a ceiling that opens up into a feature, a roof lantern works well on a rear extension or kitchen addition.

Interior spaces with no outside wall, such as a first-floor landing or an en suite, suit a sun tunnel. The tube runs between the roof and the ceiling, so there is far less structural disruption than a full window.

If you want to ventilate a loft room as well as light it, an opening unit makes sense. The electric and opening rooflights page explains the controls and the places where an electric unit is worth having.

Think about what you will do in the room as well. A bedroom wants a blind that can darken it fully, and a reading corner wants steady light without glare. A kitchen under a pitched roof wants light over the worktop, not just over the floor. Tell us how the space is used, and we match glass, size and opening type to that, instead of picking from a catalogue.
