Rooflights and skylights over the dormer bungalows of Eccleston's mature plots

St Helens made its name in glass, and rooflight installation in Eccleston centres on the quiet suburban roofs west of the town centre: concrete-tiled semis, dormer bungalows and detached houses standing on mature plots. Falling leaves test a skylight here almost as hard as rain does.

Why are so many Eccleston landings and loft rooms short of daylight?

  • The bungalow loft roomUnder the pitch of a dormer bungalow roof, where the loft was boarded and fitted out as a bedroom and the only light comes from one small gable window.
  • The semi with the inner landingUpstairs in an inter-war or 1960s semi around Eccleston Park, the landing is boxed in by bedrooms either side of a turning stair, so no outside wall gives it a window.
  • The extended back kitchenBehind a detached house on a bigger plot, a flat-roofed kitchen or garden room has been bolted on, and the old rear windows now face its walls instead of the garden.

Loft rooms, inner landings and back kitchens

Skylight installation in Eccleston covers brick terraces on the St Helens side, inter-war semis, post-war bungalows and large detached houses, and each service below is matched to one of those types.

  • Roof lanterns over larger rear extensions on the detached plots, framed to the opening the builder left and finished to match the new walls.
  • Kitchen and garden-room extensions with a single-storey flat roof get a raised kerb under the rooflight, which lifts the glass clear of leaves and pooled water.
  • For semis and bungalows roofed in concrete interlocking tile: the flashing kit is picked to suit the tile profile on the roof, not a drawing in a catalogue.
  • Older roof windows and lanterns here with fogged glazing, or with water starting to get in round the frame, are swapped for new sealed units.

A glass-making town's suburb, built in layers

Eccleston sits on the western side of St Helens, and its houses show how the borough expanded outwards from the old industrial centre. Nearest the town are the brick terraces that went up when glass, coal and chemicals drew workers in: narrow-fronted, with Welsh slate on the main roof and an outrigger at the back that often carries a lean-to or a flat-roofed kitchen. Those roofs are shallow in the loft and close-rafted, so a roof window usually goes into the rear slope, where it cannot be seen from the street.

Further out come the inter-war semis, hipped-roofed and planned around a central landing. Many of them have had their lofts converted, and the converted loft is where a rooflight earns its keep, because a dormer is a large job and a roof window is a small one. After the war the suburb filled with bungalows, chalet bungalows and dormer bungalows on generous plots, then with the cul-de-sac estates of the later twentieth century, each house roofed in concrete interlocking tile.

The larger detached houses in the leafier parts of Eccleston are the third layer. They tend to have been extended more than once, so a single house can carry a pitched tiled roof, a lean-to and two different flat roofs, all of different ages. Each of those roofs wants its own answer, and a survey is the only reliable way to match them.

Bungalows need a separate word of their own. A roof window in a chalet or dormer bungalow can double as the bedroom escape, since the room sits low enough, whereas a two-storey house's upper floor needs a different arrangement; when a roof window counts as an escape route is covered in its own answer.

Outriggers and rear extensions on the old terraces deserve a closer look. Many have had a bathroom or kitchen built into the yard over the decades, so a single house can have a slate main roof, a pitched outrigger and a flat felt roof over the extension. A rooflight over a bathroom on the flat section brings daylight into a room that often has only a small frosted window, and it can be done without disturbing the slate above.

In the semis, the loft is the larger prize. Inside an inter-war semi the roof void tends to be wide, with the original purlins carrying it well, so a conversion often needs no more than two roof windows set in the rear slope. The glazing usually goes on the rear slope, away from the street, where it lights the room just as well and draws no attention from the road.

Trees, concrete tile and flat felt: what the plots ask of a unit

Eccleston has no coastline and no hill to speak of. It lies on low, open ground in the middle of the Merseyside and Lancashire plain, so rain and wind that begin over the Irish Sea reach it across open ground, and the flashing laps are made up for that. Nothing here is as battered as a cliff-top roof, but the weather still arrives from the west and soaks the west-facing slopes in a way a sheltered valley never does.

The more particular problem is the plots themselves. Many Eccleston houses stand among mature trees, and trees drop leaves, seeds and sap. Debris piles against the upstand of a flat-roof rooflight and keeps water standing there, so the unit that sits only a little proud of the roof suffers first. A taller kerb and a fall that carries water away from the glass matter more here than they would on a bare estate. Moss is the pitched-roof version: it builds on shaded concrete tile and then lifts the edge of the flashing as it grows.

Concrete interlocking tile changes the work on a pitched roof. The tiles lock into one another, so cutting an opening means taking up a block of them, forming a new batten layout around the frame and laying the flashing to the profile of that tile. We choose the flashing kit for the tile on your roof and keep spare tiles for the surround, because tile that has weathered for forty years rarely matches a fresh one.

Bungalow lofts bring a different job. The ridge is low, so a roof window in a rear slope sits within easy reach of the ground, and the room beneath often has a boarded floor and loft insulation that must be dressed back around the new lining. On a detached house with a long drive and a wide frontage, a tower or a small scaffold is easy to place. Slate terraces towards St Helens sit on tight streets, and working from inside the loft is often the tidier way in; fitting a VELUX from the loft side says when that works.

Gutters matter as much as the unit itself under trees. A blocked gutter above a roof window sends water sideways into the flashing, so the work includes clearing the run above the opening and checking that the fall carries water past it. A guard over a lantern or a brush strip at the foot of a pitched unit keeps the worst of the autumn debris from lodging there.

Permissions in Eccleston, from planning to sign-off

Planning for Eccleston is decided by St Helens Borough Council, whose pages sit on sthelens.gov.uk. A house in this part of the borough will normally fit within permitted development, and the limits on a roof window without an application are set out separately. Flats, maisonettes and any street under an Article 4 direction fall outside that, so look at the council's own maps for yours.

Older buildings are another matter. Listed building consent is required for a rooflight on a listed house, farmhouse or chapel conversion, and the old cottages and farm buildings left standing among the later estates are where one is most likely. A house inside a conservation area calls for the same care, and a flush conservation unit is often the sensible pick; what planners look at on a protected slope is worth a read first.

We tell St Helens Borough Council's building control team about the work ourselves, and the guide to how a new rooflight is signed off explains the process. On a loft conversion we also make sure the notification covers the rooflight alongside the stair, fire separation and structure.

Estates built in recent decades often come with a builder's warranty, and the sign-off paper for a rooflight sits neatly beside it in the folder for the house.

  1. Visit. We look at the roof, the room below and the plot, and agree the unit and where it goes.
  2. Price. Nothing is booked until the figure is on paper.
  3. Notify. The council or an approver hears from us wherever the work is notifiable.
  4. Fit. We fit and dress the unit, then give you a written ten-year guarantee on the workmanship.

Eccleston roofs, answered one at a time

We have a dormer bungalow in Eccleston with a bare loft room. Can a roof window serve as the escape window?

In a dormer bungalow the loft room is low enough that a roof window can be its escape window, provided Approved Document B, volume 1 is met: an unobstructed openable area of 0.33m² or more, at least 450mm high and 450mm wide, and the bottom of the opening no higher than 1100mm above the floor. Those figures are checked against the actual room, and the order is placed only after that.

Our semi in Eccleston Park has a landing with no window. Would a sun tunnel reach it?

A sun tunnel can usually reach it, since the tube needs only a clear run from the roof to the ceiling, and on a hipped semi that run passes through the loft between the rafters. Once we have checked the route and noted any pipes or wiring, the quote names whichever fits that landing better, a tunnel or a small roof window.

Which parts of Eccleston do you cover, and do you work out towards the rest of St Helens?

Every part of Eccleston is covered, from the older terraces nearest St Helens town centre out to the bungalow and detached streets, and the rest of the borough besides. Send the postcode by phone or WhatsApp and a visit can be fixed.

Do the mature trees on an Eccleston plot affect where a flat rooflight should go?

They do, because leaves, seeds and sap settle on a flat roof beneath overhanging branches and hold water against the glass. A taller kerb and a fall that carries water away from the unit matter more under trees, and a position clear of the heaviest branches is better still.

Who tells St Helens Borough Council about the rooflight, and what do we get at the end?

We make the notification to St Helens Borough Council, or to a registered approver where one is used. Once the work has been checked the certificate comes through, and you have no forms to complete.
