The rooms in Upton houses that daylight never reaches

Village streets of semis and bungalows have been extended and converted, and the new rooms are often the ones with the least light.

  • Entrance hallA hall at the heart of a house has the front door and a pane beside it.
  • Windowless bathroomA bathroom boxed in between bedrooms has no outside wall for a window.
  • Garage conversionA garage turned living space keeps one window to the drive and a deep back.

Upton questions about windowless bathrooms and tired rooflights

They follow the way village houses are used now, with rooms added inside the same shell.

Can a bathroom with no window in an Upton house get daylight from the roof?

A windowless bathroom is one room a rooflight can change. Newer houses and conversions can put the bathroom at the core of the plan, away from any outside wall, with a bulb as its only light. A rooflight changes that by making the room a daylit one in the daytime.

What the loft allows

The first thing to learn is what sits between the roof and the bathroom ceiling. If the bathroom is directly beneath the slope, a short tube or a small roof window drops straight in. If it sits under a flat ceiling with a loft above, the tube has to cross the loft, past rafters, pipes and perhaps a water tank, so the route is walked first.

Tube or window

The two answers are a tube and a window, weighed up in choosing between tube and window. The tube is smaller, passes between rafters and keeps the opening to a minimum. The window is larger, gives more light and can open for fresh air, but it needs a wider opening and a light well. In a bathroom the tube is usually chosen, and a window when the ceiling follows the slope.

Steam and glass

A bathroom is a humid room, so condensation matters. A diffuser in the ceiling is sealed against the tube, and the lining of the tube is smooth, so water does not collect inside. A roof window used in a bathroom is chosen with glazing that stays warm on the inside face, and a fan or an opening sash clears the steam. Rooflight condensation forms when warm, damp air from the room meets a cooler surface.

Fan or no fan

A bathroom with no window usually has an extractor fan, and that stays. A rooflight adds daylight without replacing the fan, and the two work side by side. The fan clears the steam after a shower, and the daylight does the job of the bulb.

Privacy

A tube has no view in or out, because its diffuser is frosted. A roof window in the slope is high above anyone on the ground, and a blind can be added for the few cases where a neighbour's window looks down on it.

Finishing indoors

The ceiling is cut cleanly and the diffuser or the well is finished as the quote describes. The bathroom floor is covered during the work, and plastering round the opening is part of the job, so the room is ready to paint when we leave.

On a house, a rooflight usually comes under permitted development, and the planning guide lists the conditions. Paperwork for any change to the structure is separate, and we look after it.

Where does the light come from in a garage conversion in Upton?

A garage in a village semi may by now be a playroom, a study or a spare bedroom. The front becomes a window or a bricked-in panel facing the drive, and the room runs back a long way beyond it. The back is where the shade lies.

Flat or pitched roof

Garages are built with a flat roof or a pitched one, and sometimes a lean-to slope. The shape of the roof sets the unit. A flat roof rooflight sits on a kerb above a flat deck, and a roof window sits in a pitched slope between rafters. Both put the light over the middle of the floor.

Where to put it

The best place is above the deepest part of the room, the farthest point from the window. A bed, a desk or a play area is placed there, and light arriving from straight above reaches the corners that the front window cannot. We chalk the spot on the floor, then check it against the joists or rafters overhead.

Insulation in the roof

A converted garage has been insulated for use as a living space, and the roof was part of that work. A new opening cuts through the insulation, so the gap round the frame is filled to keep the warmth in. The glass is chosen so the room does not lose what the insulation has gained.

Roof covering

A flat garage roof is often felt or a rubber sheet, and the covering is lifted and turned up the kerb. If the roof is old, it is worth asking whether the covering will need replacing soon, because that is the cheapest moment to add a rooflight. A pitched garage roof takes the flashing for its tile or sheet.

Light at the right height

Overhead light falls evenly, so a desk or a bed anywhere under the unit is well lit. A light from the front window comes in low and sideways, and it dies away. Together the two make a room that works from front to back.

The conversion itself

Turning a garage into a living room is itself building work under the Building Regulations. A new rooflight is a separate piece of work and is treated on its own terms. Planning conditions for houses are covered by our planning guide, and Wakefield Council is the place to ask if the house has a listing or sits in a protected area.

If the garage is attached to a bungalow, the roof may be continuous with the house, which opens up other options, including a window in the main slope.

Reading a garage roof from inside and out

Whether the roof is flat or pitched, where the insulation sits in it, and how far the room runs back from its one window.

How is an old misted rooflight in an Upton house replaced?

Rooflights fitted in a house extension years ago may now show fog trapped between the panes. That fog tells you the seal along the unit's edge has given way. The moisture sits inside the sealed gap, where no cloth can reach, and it is there for good.

Glass only or the whole unit

In some rooflights the sealed glazed unit can be lifted out of its frame and a new one fitted. In others the frame and glass are one piece, so the whole rooflight is replaced. We look at the frame, the kerb and the covering, and advise which route is right. Either route cures the same fault, because when rooflight glass mists between the two panes, the edge seal has failed and let damp air into the gap.

The same opening

If the new rooflight is the same size as the old one, it goes into the opening that is already there. The rafters or joists stay as they are, which keeps the job smaller. A larger unit needs the opening widened and the structure re-framed, and that is notifiable work. For a pitched roof, see swapping a roof window for the same size.

What the old kerb tells us

On a flat roof, the old kerb and its covering are looked at while the rooflight is off. A soft timber or a lifting covering is dealt with before the new unit is bedded, because a new rooflight on a tired kerb will leak in time. If the kerb is sound it is reused.

Old rooflights in Upton houses

Older rooflights in village houses can sit on rear extensions and conservatories added over the years, and each has its own age and make. We identify the make where we can, and measure the opening either way, so the quote covers a unit that fits.

A chance to improve the glass

An older rooflight is likely to be single-glazed or an early double-glazed unit. The replacement is double-glazed with a coating and a better spacer, so the room loses less heat than before. On a flat roof, a model that opens can also be chosen at this stage, for ventilation.

Plaster and paint

The plaster around the opening is checked, and any area stained by damp is replastered and finished as the quote says. The floor is covered while the old unit comes out.

Each replacement is quoted at a fixed price in writing for a named unit at a given size, so the quote tells you what will be in the roof afterwards.

Short answers for Upton households

Do I have to do anything about Building Control in Upton?

We notify Building Control ourselves, using Wakefield Council's service or a registered building control approver, so you do not need to apply separately. The notification also takes in any cut to the roof structure.

Is a sun tunnel suitable for a bungalow with little loft?

A shallow loft gives a short run, which suits a tube because the light has little distance to travel. The route is checked for rafters and wiring, and a rigid tube is used where it can be.

Is a rooflight over a bathroom noisy in rain?

Rain on the glass of a rooflight makes a gentle sound, which varies with the glazing. Thicker or laminated panes quieten it, and a dome on a sun tunnel is smaller than a window, so less rain lands on it.

Can I choose a flat rooflight that opens?

A flat rooflight can be made to open by hand or by a motor, which suits a kitchen or bathroom needing ventilation. Certain models close by themselves when a built-in sensor feels rain.
