Installing a skylight and rooflight in low 1960s roofs across Partington
Low-pitched 1960s roofs, flat-roofed extensions and a flat landscape of moss and canal define the houses of Partington. Rooflight installation in Partington means working with shallow slopes, concrete tile and felt, and open ground where wind has a clear run at every roof, with a skylight chosen to suit each one.

What leaves so many Partington homes short of daylight?
- The deep-plan terraceIn a 1960s terrace with a deep floor plan, where a central stair and a bathroom sit away from both the front and back walls and never see a window.
- The flat-roofed rear extensionA semi whose flat-roofed kitchen or garden room leaves the middle of the floor dim, because light arrives from one side only.
- The maisonette stairwellUp the shared stairwell of a low-rise block or maisonette, where a roof opening above the top flight is the only way daylight can reach the lower landings.
Deep-plan terraces, flat extensions, maisonette stairs
Housing in Partington ranges from 1960s terraces and low-rise blocks through semis and bungalows to newer estate homes, and skylight installation in Partington follows that range, from small sun tunnels to full lanterns.
- Lanterns for wider rear extensions on larger semis, giving a flat-roofed room more height and light without a full structural change.
- Rear extensions, porches and garages roofed in felt or single-ply take flat rooflights on an upstand, with enough fall for the water to clear.
- Roof windows for the shallow tiled pitches of 1960s houses, chosen for a low slope where a standard unit would sit too flat.
- Better-glazed rooflights for houses where the roof loses heat quickly, chosen against the thermal limits for existing dwellings.
A planned estate on flat land that was once mostly moss
Partington's housing has a clear starting point. The village was greatly expanded in the 1960s, when large numbers of homes were put up quickly to rehouse families from Manchester and its suburbs. Streets of terraces and semis were laid out on a plan, with low-rise blocks and maisonettes in places, and the result is a town whose roofs share a family resemblance far more than most of the older places on the Merseyside side of the region.
Many of those 1960s houses have shallow-pitched roofs, covered in concrete tiles or in some cases in profiled sheet, with simple timber construction. The pitch is low enough that standard roof windows need checking against their minimum angle, and flashings must be fitted to suit. Where a pitch is too shallow for a conventional unit, a flat rooflight or a window designed for low slopes is the better choice. The lofts are often only just big enough for storage, so owners who want a room up there usually end up combining roof windows with a rear dormer or an extension.
Extensions are the second layer. Over the decades, owners have added flat-roofed kitchens, utility rooms, garages turned into extra rooms and conservatories rebuilt with solid roofs. Each of these adds floor area and takes away daylight from the original house behind it. Flat rooflights and lanterns earn their keep over these extensions, since each one lights a room that has one window at most.
On the village edges the newer estates are brick and block under insulated tile roofs, carried on modern timber trusses, so the trusses are checked before any opening is cut. Between all these types, the one common feature is the ground itself: flat, low and open, on the edge of the moss and close to the canal.
Maisonettes and low-rise blocks need their own thinking. The roof over a block is shared, often flat or nearly so, and a rooflight above a stairwell serves several households. Permission from whoever owns or manages the roof comes before any quote, and the structure over the stair, usually a concrete or steel-supported deck, is checked for what can be cut.
- The pitch of the slope against the minimum angle for the chosen unit
- Whether the roof is tile or profiled sheet, which sets the flashing type
- Truss spacing in newer houses, because trusses cannot simply be cut
- Whether a flat extension roof has the fall and deck to take a kerb
- Where the shared wall or stair sits in a terrace or maisonette
Nothing stands between the roofs and the weather on this flat ground
Partington lies on level land with the Manchester Ship Canal beside it, the Mersey close by, and the open expanse of Carrington Moss to the east. There are no hills here to take the edge off the wind, and few tall buildings to shelter a row of houses. The result is a roof that meets the wind head on from most directions, and a rainstorm that arrives across open fields with force. So fixings and flashings matter here more than appearance does.
On a low-pitch tile roof, rain driven across the slope can be forced under a flashing that would hold on a steeper roof. A roof window for a shallow pitch needs a flashing kit and underlay detail designed for that angle, and the lap at the head and sides is generous. Concrete tiles on these houses are often interlocking, so they do not open up cleanly, and each cut is made to leave the neighbouring tiles locked in place.
Flat roofs get a different kind of attention. Many of the extensions have felt roofs that are now past their best, and a rooflight is raised on a kerb built up from the deck, so the covering around the opening must be sound enough to hold the new waterproofing. A shallow fall, or none at all, leaves water standing against the kerb, which is why the upstand height is chosen with the fall in mind. Ponding is more common on flat roofs here because the extensions were often built with little pitch.
Ground conditions are no concern for a roof job, but access is. Streets are wide and plots open, so a tower or small scaffold can usually stand clear of the house. In a terrace or block with shared walls, the roof may be reached only from the rear, and the work is planned around neighbours' access and the stair. On a gentle slope above a clear loft, a roof window can sometimes go in from the loft side.
Wind also affects the day of the work. A lantern or a large flat rooflight is lifted into place in one piece, and a gusty day on open ground can make that unsafe, so the fitting date is kept flexible and the unit is not hoisted until it can be lowered under control. Temporary weatherproofing goes over any opening left at the end of the day.
Condensation deserves a mention for houses of this age. Thin roof insulation and a cold ceiling plane mean warm, damp air from a bathroom can condense on a poorly lined opening, so the splay inside is insulated and the glazing is chosen with its thermal performance in mind. A rooflight with better glazing often feels warmer in the room than the old plastic dome it replaces.
A low-pitch tile roof
- Check the angle against the unit's minimum
- Use a flashing kit for shallow slopes
- Keep interlocking tiles locked either side
A flat extension roof
- Read the deck and the fall first
- Build the kerb up to clear standing water
- Tie new membrane into the upstand
Trafford Council, and who answers which question about a rooflight
Partington is in the Trafford borough of Greater Manchester, and Trafford Council is its local planning authority. That makes it a different regional setting from the Merseyside towns on the rest of our patch, though the rules are the same English ones. For an ordinary house a rooflight is usually permitted development, and the conditions behind that are covered in that separate guide, so they are not repeated here. Low-rise blocks fall outside those rights: a flat or maisonette has none for rooflights, so the planning check comes before the order.
We are not certain of any conservation area that covers the 1960s housing of Partington, and we would rather not name one. If your home is older, listed or subject to a direction that removes permitted development, Trafford Council can tell you before you commit, and listed building consent applies to any listed building. Historic England publishes guidance for owners of listed buildings, and the page on rooflights in protected streets helps if your street turns out to be protected.
Before work starts at a Partington house, Trafford Council's building control service gets our notification, and what the standards ask of an existing home has its own guide.
Lofts need a final word. A loft bedroom over a two-storey house is not served by a roof window as a way out, because an escape window counts only on a storey within 4.5m of the ground; that conversion needs a protected stair. A bungalow with rooms in the roof is the exception, and there a roof window works as the escape if its opening meets the Approved Document B sizes.

Rooflight queries from Partington homeowners
Is the roof on our 1960s Partington terrace too shallow for a roof window?
A roof window will work if the slope is above the minimum angle for the unit, and many 1960s roofs sit near that limit. We measure the pitch at the survey and choose a window and flashing kit made for it. If the slope is too low, a flat rooflight is the usual alternative.
The felt on our flat extension roof is old. Can a rooflight go in it?
A rooflight can go into a flat extension roof, provided the deck and fall around the opening are sound. We build a kerb up from the deck, tie the new membrane into it and check that water cannot stand against the glass. The survey tells you what the roof needs.
Would a sun tunnel reach the bathroom in a deep-plan 1960s terrace?
For the inner bathroom of a deep-plan terrace, a sun tunnel fits well: a small cut in the roof lets a tube drop through the loft and end in a diffuser on the bathroom ceiling. On a low pitch the tube has a short, nearly straight run.
Can a flat or maisonette in Partington have a rooflight?
Permitted development for rooflights stops at houses, so a flat or maisonette in Partington starts with a planning enquiry to Trafford Council. Any shared roof also needs the freeholder or management company to agree before work is booked.
Our garage conversion on the estate has a pitched tile roof. Can it have a roof window?
A converted garage with a pitched concrete-tile roof can take a roof window if the pitch is above the unit's minimum angle and the rafters allow an opening between them. The tile profile sets the flashing kit, and the interlocking tiles either side are kept locked in place when the opening is cut. A garage conversion is often a deep, dim room, so the extra light is felt at once.
