Flat rooflight on the single-ply roof of a terraced house extension

A rooflight and skylight for Roby's older villas and the semis of Huyton

Rooflight installation in Huyton mostly means tiled roofs: inter-war semis with hipped slopes, council-built estate houses from the post-war years and the older villas of Roby. A skylight here is chosen to suit the tile profile and the roof timbers underneath, which differ from one street to the next.

Which parts of a Huyton house are left in permanent half-light?

  • The Roby villa stairwellUp the tall stairwell of a Roby villa, where a Victorian window on the half-landing lights the bottom flight and leaves the top floor in shadow.
  • The estate-house box roomIn the box room of a post-war estate house around Page Moss or Woolfall Heath, a room with one small window that could take a loft-slope rooflight instead.
  • The extended semi's hallwayAlong the hall of a Huyton Quarry semi that gained a rear extension, where the new room swallowed the old kitchen window and the hall got nothing in return.

Villa stairwells, estate box rooms and semi hallways

Skylight installation in Huyton has to fit Victorian villas in Roby, cottages by the old village, 1930s semis, post-war estates and newer cul-de-sacs, and the services below are sorted by what each of those roofs allows.

  • On Roby's larger detached and semi-detached houses, a lantern over a rear kitchen-diner adds overhead light to what the garden doors already give.
  • On a Huyton semi, a converted garage or rear extension can be lit from above by a flat rooflight on a low kerb, with no work to the walls.
  • Roof windows set into the concrete interlocking tiles of estate houses, with flashing kits matched to the tile profile so the surround sits flat.
  • A rooflight that opens at the touch of a wall switch or remote, letting heat escape from a stuffy first-floor landing.

Villas, village streets and the semis that filled in between

Railways shaped Victorian Huyton. The Liverpool and Manchester line gave the old village a station, and the houses that followed were homes for people who worked in the city and wanted a garden. That is why Roby has Victorian and Edwardian villas, some with three floors, steep pitched roofs and a stairwell that runs the full height of the house. Natural slate was the covering of that period, and some of those slopes have since been re-covered in tile or artificial slate.

The older heart of Huyton, around the parish church and the village roads, mixes cottages and short terraces with later infill. Roofs there are small, often steep, and the loft rooms are low. A rooflight in a roof of that size has to be chosen by the centimetre, because a unit a little too wide leaves no rafter to carry the trimming.

Most of Huyton's housing arrived in two waves, the 1930s and the decades after 1945, as the edge of Liverpool pushed outward. Brick to first-floor level and hipped tile above: that is the 1930s private semi, and its landing is boxed in at the centre of the house with no outer wall to borrow light from. Council estates followed, among them the roads around Page Moss and Woolfall Heath, and many of those houses were later bought by their tenants. Their roofs are plain, usually concrete or clay tile, with a ridge that runs the length of a pair of houses and a chimney stack at each end.

Later building, from the 1970s on, filled the gaps with cul-de-sacs of detached houses and short rows of town houses. Their roofs are built from factory-made trussed rafters, and that matters for rooflights, because a truss cannot simply be cut through. Houses of every period have collected extensions as well: flat-roofed kitchens, converted garages and loft rooms that rely on roof windows for what daylight they get.

Many a Huyton project begins in the loft. A hipped 1930s roof gives a good rear slope for a pair of roof windows, while an estate house with a shallow pitch may offer only a narrow strip of usable height. Whether the room can take a rooflight, and where, depends on the rafters, the ridge height and the way the stairs arrive, not on the size of the house.

Concrete tiles, trussed roofs and what sits behind the opening

Huyton lies well inland, so it misses the worst of the salt-laden gusts that hit the coast. It is not sheltered, though. The prevailing wind still arrives from the south-west across the flat country on the Liverpool side, and the estates were laid out with wide gaps between the house rows. Wind gets round a gable end and under the verge of a hipped roof, which is why verge and ridge details on estate houses loosen with age.

Before anything else, we look at what covers the roof. Most Huyton houses of the last ninety years wear tiles, and the profile varies between the small plain tile of a 1930s semi and the deep interlocking concrete tile of a later estate. Every profile needs its own flashing kit. A kit made for one tile will not close against another, and water finds the gap. We match the kit to the tile on your roof, which also tells us whether tiles can be lifted and reused around the new opening or whether a few spares from a merchant will be needed.

Under the covering, there are two kinds of roof. Inter-war semis and the older villas were framed in cut timber, with rafters, purlins and a ridge board that a carpenter can trim around. Houses from the 1970s onward use trussed rafters, whose diagonal webs carry the roof's weight. A roof window can sometimes sit between two trusses if the unit is narrow enough. A wider opening needs a trimmer and a structural calculation first, and we raise that at the survey rather than on the day.

Flat roofs are the second job. Garage conversions, rear kitchens and porches on Huyton semis are often covered in single-ply or felt, and the question for a flat rooflight is the deck underneath. Boards that have stayed damp for years go soft at the edges, and a kerb needs sound timber to fix to. If the covering is tired, renewing it as the kerb goes in avoids paying for access twice; the kerb itself has to do a specific job, described in how an upstand keeps a flat rooflight dry.

Access in Huyton is easier than in a town of tight terraces. A drive or front garden comes with most estate houses, so a tower or short scaffold can stand clear of the pavement. Roby's tall villas are different, because the eaves can sit high enough that a full scaffold is the safe way to work.

  • The tile profile, so the correct flashing kit is ordered
  • Cut rafters or trussed rafters in the loft
  • The hip and ridge lines near the planned position
  • The deck beneath any garage or porch roof
  • Where the soil vent pipe and the boiler flue come through the slope

Knowsley Council, the older streets and getting the work signed off

Whether a Huyton road has special protection is a question for Knowsley Council, which also takes the planning applications. On the back slope of an ordinary house, a rooflight rarely needs an application; the conditions are set out separately. Slopes facing the road are looked at harder, and when a front-facing roof window becomes a planning matter is dealt with in a separate guide.

Knowsley has listed buildings and designated conservation areas, and we do not guess which side of a line a particular road falls on. If your house is old, in the village, near the parish church or on one of the older roads in Roby, check the map on knowsley.gov.uk or ask the council before you order anything. On a protected road the usual answer is a flush conservation unit, as described under low-profile units for older streets. Listing is stricter, and the council's consent comes before any work on a listed house.

Flats and maisonettes are worth a separate thought. Blocks of them stand in Huyton alongside the houses; a flat has none of the permitted development rights a house enjoys, which puts both freeholder and council in the decision. A former council house bought under the right to buy can also carry conditions in its title papers, and the solicitor's file from that purchase is worth a look.

In Huyton, a rooflight is notifiable work, and we lodge the paperwork with Knowsley Council's building control; one guide sets out what the regulations ask of a replacement unit.

  1. Survey. We look at the tiles, the timbers and the position, and note whether the street has extra protection.
  2. Quote. A fixed figure goes to you in writing, naming the unit and the flashing.
  3. Installation. The unit goes in, the framing and flashing are left open to inspection, and the room is cleaned.

Huyton roofs, Knowsley paperwork

The loft of our Roby villa has an old rooflight over the stairs. Can that be replaced with a modern one?

A stairwell rooflight in a Roby villa is among the easiest things to replace, because the opening already exists and the framing is in place. We check the size, the flashing and the condition of the timber at the survey, then fit a new unit that meets today's thermal standards.

We bought our former council house in Page Moss and the loft has trussed rafters. Is a roof window still possible?

A trussed loft in Page Moss can still take a roof window: a narrow one may sit between two trusses with no structural change, and a wider one needs trimming and a calculation for the new framing. We look in the loft at the survey, tell you which route your roof needs and include any engineering in the written quote.

We are in Woolfall Heath. Is that close enough to be covered by this page?

Woolfall Heath, Page Moss, Huyton Quarry, Roby and the roads of the old village all come under Huyton for our purposes, so nothing about your address needs checking first. Houses in the Quarry streets, on the Roby side and out past Woolfall Heath share the same tiled, semi-detached character, so one set of advice applies across all of them.

Our Huyton semi has a hipped roof. Does the hip limit where a roof window can go?

A hip takes away the straight run of rafter you get on a gable roof, so the best slope for a window on a 1930s Huyton semi is usually the rear main slope, clear of the hip and the chimney stack. We mark the position against the hip and ridge lines in the loft at the survey.

Does the wind across Huyton's open estates matter when choosing a rooflight?

The gaps between estate house rows let the south-westerly reach verges and ridges with little shelter, so we choose a flashing kit that matches your tile profile and bed it firmly. A loose verge near a new opening is something we point out at the survey rather than leave to chance.
