Skylight Installation in Romford
Skylight and rooflight installation in Romford: dense victorian and edwardian terraces, and what that means for specifying a rooflight here.
Romford sits on flat, low ground where the River Rom runs down towards the Thames, and that flatness governs almost every rooflight decision in the town. There is no hillside here to hand a roof an open aspect. Instead the streets run in long terraced rows, and which way your usable rear slope points was settled by the grid the Victorians laid out, not by any view. On one side of a street the back roof takes the afternoon sun; on the mirror side it sits in shade for most of the day. Read that aspect correctly and choose the glass to match it, and a Romford roof will carry a great deal of light. Read it wrong and you either cook a small back room through the summer or waste a north slope on glass that gathers no warmth at all.
The roofs Romford is built from
Romford started as a market town and then swelled outwards along the railway, and the roofs still record the order it all happened in.
Closest to the centre and strung along the lines are the Victorian and Edwardian terraces. These are steep-pitched roofs in natural slate or plain clay tile, sitting on narrow footprints, one house pressed hard against the next under a shared party wall. Most of them grew a rear back-addition at some point, the outrigger wing that runs back into the yard, and that wing usually carries a lower lean-to slope or a flat roof of its own, tucked in behind a valley gutter. The main roof is tall and the plan is deep, which is a promising combination for a loft, and a difficult one for daylight lower down.
Behind and around those terraces came the interwar surge, and there is a lot of it in Romford. The 1920s and 1930s filled the ground between the old town and the borough edge with bay-fronted semis and short terraces, hipped roofs in concrete or clay interlocking tiles, moderate pitches, running in long consistent runs where one house repeats the next for a whole street. Some of the planned suburban developments from that era were built to a more careful pattern, with steeper roofs, deeper eaves and more variety in the ridge line than a standard speculative semi. Those are worth identifying early, because a more architecturally consistent street is exactly the kind a London borough may choose to protect.
Then comes the later stock: post-war rebuilding, borough housing and modern infill, with shallower pitches and trussed roofs where the structure is a factory-made frame rather than cut timber. A trussed roof will not give up an opening the way a purlin-and-rafter roof will, so on those the size of the rooflight is decided by the framing before anything else is discussed.
Four broad groups, four different answers. What suits a slate terrace in the town would be wrong on a 1930s semi, and neither approach transfers cleanly to a trussed post-war roof.
Flat ground and the aspect lottery
Southend, the city this business is built around, faces south across the Thames Estuary and gets its light off open water. Romford is nine miles or so inland from that frontage and could hardly be more different. The ground here is flat, the town sits low in the Rom valley, and nothing about the setting hands a roof a free aspect. Everything comes down to which way the terrace happens to run.
Because the streets were laid out in parallel rows, a whole street usually shares one aspect on its rear slopes, and the street backing onto it shares the opposite. Cross one road and the roof you were looking at flips through 180 degrees. So the first question on any Romford enquiry is not the size of the opening. It is: which way does your good slope actually face, and what does it receive across a year.
The second factor is overshadowing, and on flat ground it does more than people expect. A rear slope in a terrace is rarely open to the sky. There is the mirror terrace behind, there are the neighbours’ back-additions stepping into the plot, there are taller interwar houses on the corners. Low winter sun in particular gets blocked long before it reaches a roof. That is very different from an exposed coastal slope, and it changes the sums. A south or west slope in Romford can still overheat badly in summer, especially over a small enclosed back room where the heat has nowhere to go, but a north or north-east slope here is genuinely dim, dimmer than you would guess, because the neighbours take what little low light there is.
So orientation-first still runs the job, exactly as it does on the coast, but in Romford it splits both ways. On the sunny slopes the priority is holding heat out. On the shaded ones it is pulling light in. The glass has to follow the aspect, and half the town needs the opposite specification from the other half.
One thing Romford does not have to fight is the sea. There is no salt spray reaching these roofs and no gale coming off open water, so the material argument that dominates a cliff-top job matters less here. Age and soot on the older slate matter more. A century-old London roof has usually seen work over the years, and the condition of the covering around a proposed opening is worth checking before the unit is ordered.
The dark middle room
The single most common daylight problem in a Romford terrace has a shape you can draw. The plan is deep and narrow. The front room takes the street window, the back room or kitchen takes the garden window, and the room in the middle, the one between them, has no external wall of its own along the long sides of the house. It is boxed in by the neighbours left and right and lit only by whatever borrowed light struggles through from either end. In a lot of these houses that middle room is the darkest space anyone lives in.
The roof gives you a way out of it. The back-addition wing that runs into the yard usually carries a flat or shallow lean-to roof at a lower level than the main slope, and that roof often sits right over, or right beside, the dark part of the plan. A flat-roof rooflight or a small roof lantern dropped into that lower roof brings daylight straight down into the middle of the house without anyone touching the visible slate of the main roof at all. From the street nothing changes. Inside, a room that needed the light on at midday stops needing it.
Where the flat is genuinely flat, a fixed or opening flat-glass unit sits neatly and sheds water on a slight fall. Where there is room and appetite for more glass, a modest lantern lifts the light and adds a little height to the ceiling below. Either way, this is the move that changes a terrace most, and it is worth considering before anyone starts planning a large opening in the steep front-facing slate where the planning questions are harder.
Specifying the glass for a Romford roof
The unit itself is the straightforward part of any job. What decides whether you are pleased with the room in July is the glass, and in particular two numbers.
The U-value describes how fast heat leaks out in winter, measured in watts per square metre per kelvin, and lower is better. Part L of the Building Regulations sets a level the unit has to reach. The G-value describes how much of the sun’s heat the glass lets through, on a scale from 0 to 1. A clear double-glazed unit runs a G-value close to 0.6, so roughly six-tenths of the solar energy landing on it passes into the room. A solar-control unit pulls that down towards 0.3, letting through about half as much. On a small, enclosed Romford back room facing the sun, that gap is the difference between a room you sit in and a room you avoid.
| Unit build-up | U-value, typical (W/m²K) | G-value, typical | Best matched to |
|---|---|---|---|
| Clear double glazing | about 1.6 | about 0.6 | North and north-east rear slopes, and shaded back-additions, where the aim is to grab every scrap of daylight |
| Solar-control double glazing | about 1.4 | about 0.3 | Any south or west slope, and small enclosed rooms that heat up fast |
| Solar-control triple glazing | about 1.0 to 0.8 | about 0.3 | Loft bedrooms and quieter rooms, where winter warmth and a little sound reduction both count |
| Obscure or laminated solar-control | about 1.4 | about 0.3 | Side-facing units below 1.7 metres and anywhere a neighbour is overlooked |
Those numbers are industry-typical and shift with the maker and the size of the unit, so read them as the shape of the choice rather than a fixed quote. The point that holds for Romford is the split. This is not a town where one glass answer fits every roof. A sunny slope wants solar control as its starting point, not as an upgrade, and a shaded slope wants clear glass so it is not throwing away light it cannot spare. Choosing the aspect wrong costs you either way. There is more on the trade-off in our guide to energy-efficient skylight installation.
Planning and Building Control in a London borough
Romford is not in Essex for planning purposes. It sits inside a London borough, and the London Borough of Havering is both the planning authority and the Building Control body for the town. That matters, because the permitted-development picture across London is not identical to the one across Essex, and London boroughs carry a greater number of Article 4 Directions than the counties around them.
As general guidance, a rooflight on a house is often permitted development. The usual conditions are that it stays below the ridge line, stands no more than 150 millimetres clear of the roof surface, and, on a side-facing elevation below 1.7 metres, uses obscure glazing with a restricted opening. Meet those and, on an ordinary house, a planning application is frequently not required. That is the general rule, not a ruling on your roof.
The exceptions are where London gets its own character. Flats and maisonettes never carried rooflight permitted-development rights in the first place, and a great deal of Romford’s stock has been converted into flats. Listed buildings need consent for the work regardless of the roof. And where a borough has placed an Article 4 Direction over a conservation area, the permitted-development right for changes to roofing materials or windows can be withdrawn, which means an application is needed for work that would be automatic a few streets away. Havering has areas of protected character, and the more architecturally consistent interwar and garden-suburb streets are exactly the sort a borough tends to safeguard.
Because the boundaries and the directions do not follow any line you could guess from a street name, the sensible first step on any Romford enquiry is to establish the property’s exact status with the London Borough of Havering before committing to a unit. We will always point you to the council’s own mapping rather than rely on what a neighbour was told when they had a rooflight fitted years ago. Where an application is needed, the specification you apply with makes a real difference: a unit that sits flush in the plane, in a dark slim frame, on a slope out of the main public view, reads far better to a planning officer than a large modern box standing proud of a street elevation. Nobody can promise consent, but the way the job is put together is not neutral.
Getting a scaffold to the roof: access in Romford
Access is often the part of a Romford job that decides the timescale, and it divides sharply along the same lines the housing does.
On a Victorian or Edwardian terrace there is usually no side access at all. The houses meet at the party wall, so the only way to the rear roof is through the house itself or over a shared rear boundary, out into a narrow yard or a back alley that was never built with a scaffold lorry in mind. Add the parking controls that come with a dense London borough, the permit zones and the loading restrictions, and the practical question of where materials can even be set down becomes part of the plan rather than an afterthought. On the tightest terraced plots that means a smaller tower, a longer hand-carry down the side return or through the house, and a slower first morning. It is far better to know that at the survey than to find it out on the day.
The town centre adds its own friction. Around the market and the main shopping streets, congestion and controlled parking mean timing and access have to be arranged rather than assumed.
The interwar semis are the easy end of Romford. Those plots generally have a side return, driveway space and predictable eaves heights, so scaffold goes up in a standard configuration and the interesting decisions move inside, into the roof structure. The back-addition roofs on the older terraces are the fiddly end: low, tight and hemmed in, straightforward to work on once you are there but not always simple to reach.
What we typically install, by property type
Matching the unit to the roof is most of the craft. Here is how it tends to fall across Romford.
| Property | What usually suits it | Reason |
|---|---|---|
| Victorian or Edwardian terrace, steep slate or plain tile main slope | Roof windows to the rear slope, glass chosen to the aspect; a conservation-style flush unit where the street is protected | The tall main slope is the loft’s best light, and a flush dark-framed unit is the safer bet where character is guarded |
| Terrace back-addition, flat or shallow lean-to roof | Fixed or opening flat-glass rooflight, or a small lantern, solar-control by default | Lights the dark middle room without altering the visible slate, and the sunny back-addition heats up fast when it faces the wrong way |
| 1930s semi, hipped concrete or clay tile roof | Standard roof windows to the rear slope, solar-control on any south or west face | Predictable cut-timber structure and simple flashing, with the rear slope usually the one worth glazing |
| Garden-suburb or planned interwar house, steeper varied roof | Roof windows or a lantern, specified to sit right on the roof, with the planning position checked first | These streets are more likely to be protected, so the unit and the application have to be considered together |
| Post-war or modern, trussed roof | Smaller openings between the trusses, or a structural alteration designed before anything is cut | Factory trusses cannot simply be removed, so the framing sets the size of the opening |
Where a unit has already failed, misted between the panes, lost its seal or simply dated so far that it drags the room down, fitting a new unit into the existing opening is our work, and it usually goes faster than people expect because the hole is already there. If what you are looking at is a roofing fault rather than a glazing one, a roofer is the right trade for that, and we will tell you so plainly.
Building Control and the shape of the week
A new or enlarged rooflight is notifiable under the Building Regulations. Part L sets the thermal bar the unit has to clear, which is why the glass specification is not a free choice. Part K covers safety in overhead glazing, which is the reason the inner pane sits laminated so it holds together above your head. We make the Building Control notification to the London Borough of Havering on your behalf as part of the job. You do not register anything and you do not chase it.
Where the property sits inside a protected area, the planning step comes first, and there is no sense ordering a particular unit until you know an application is going in and on what basis.
A typical Romford install runs in this order:
- Survey. We get onto the roof, check the structure from inside, read the aspect and work out what the slope receives through the year, and establish the planning status with the borough.
- Specification. Unit, position, size and glass, with the G-value settled here against the aspect, and honest pushback if the plan is clear glass on a sunny slope or heat-rejecting glass on a shaded one.
- Planning, where a protected area calls for it, alongside the Building Control notification.
- Access. Scaffold or tower designed to the actual plot, which on a terrace is the part that takes the thought.
- Install. A single roof window in a straightforward semi is usually a day. A pair in a converted loft runs a day to two. A flat rooflight or lantern on a back-addition depends on the roof it is going into.
- Making good inside, and the roof left watertight and tidy.
Every installation carries our ten-year workmanship guarantee, and we have been fitting skylights and rooflights for over fifteen years. Indicative figures by unit type sit on our costs page, and if you would sooner have a number for your own roof, the quote form takes about a minute.
Romford skylight questions we get asked
Do I need planning permission for a rooflight in Romford?
It depends on the property and where it sits. On an ordinary house, a rooflight that stays below the ridge and stands no more than 150 millimetres clear of the slope is often permitted development. But Romford is in the London Borough of Havering, flats and maisonettes never had that right, listed buildings need consent, and an Article 4 Direction over a protected area can remove the right for roof and window changes. Confirm your property’s status with Havering before you commit.
My back room is dark. Can a skylight really solve that?
In a deep terrace, often yes. The middle room in these houses has no window of its own, but the back-addition behind it usually has a flat or lean-to roof at a lower level. A rooflight dropped into that roof brings daylight straight down into the darkest part of the plan, and it does not touch the slate on the main roof or change anything you can see from the street.
Which way should my rooflight face?
You do not choose the aspect, the terrace does, and that is the whole point of surveying it first. A south or west slope wants solar-control glass near a G-value of 0.3 so a small room does not overheat. A north or north-east slope wants clear glass so it is not throwing away light it cannot afford to lose. The correct glass on the wrong slope is still the wrong glass.
How do you get a scaffold up when there is no side access?
Carefully, and it is planned at the survey rather than improvised on the day. On a terrace with no side return, access to the rear roof runs through the house or over the back boundary, materials are hand-carried, and the parking and loading rules of the borough are worked into the plan. It is one of the reasons a terrace job can take a little longer than a semi even when the fitting itself is the same.
Do you handle the paperwork with the council?
We make the Building Control notification to the London Borough of Havering on your behalf as part of the installation. Where a protected area means a planning application is needed, we will set out what the borough is likely to be looking at and specify the unit to suit, though the consent itself is always the council’s to give.
How long does an install take?
A single roof window in a straightforward roof is usually a day. A pair in a loft conversion runs a day to two. A flat rooflight or a lantern on a back-addition depends on the roof it goes into and the opening size. On a tight terrace, add time for access rather than for the work.
We install across Romford and out through the wider spread of south Essex towns, with Romford sitting at the London edge of the area we cover, roughly twenty-nine miles by road from Southend. Wherever your roof is, the conversation starts the same way: which slope, which aspect, and what the glass has to do about it. Everything else follows from that.
