Under Marshfield's roofs
Long street, stone walls, steep gables
Marshfield grew along a single long street, and the old houses still crowd the pavement with their gable ends and chimney stacks. Behind the frontage sit yards, outbuildings and a scatter of newer housing. Each of these asks something different of a rooflight, and the answers begin with who built the roof and when.
Stage 01 · Housing stock
Frontage houses and what lies behind them
Walk the length of the High Street and the Cotswold stone does most of the talking. Some houses present a gable to the road, others a long eaves line, and plenty hide a second range, a lean-to or a converted barn out of sight in the yard. A good many are on the statutory list. Before we measure anything, the survey establishes which of these we are standing in, because that decides which products can even be considered. We also take a little time over the character of the street, since a unit that is plain on one rear slope may look wrong on another.
The coverings change house to house. Stone slate crowns the older buildings, clay pantiles turn up on others, and where a roof has been renewed in living memory you may find ordinary concrete tile. The flashing for a rooflight is ordered for the covering actually on your slope. A kit that suits one will not close properly on another.
Behind the old frontage, the village has newer brick and reconstituted-stone housing on trussed roofs, usually with a garage or small rear extension. These raise a different puzzle. When an estate was granted permission, the council sometimes withdrew householder rights by condition. The decision notice settles it, and we ask to see it.
| Building | Roof | Looked at first |
|---|---|---|
| Frontage house | Stone slate or pantile | Listing and conservation boundary |
| Converted barn or outbuilding | Mixed old coverings | Timber layout, planning history |
| Estate house | Concrete tile, trussed rafters | Any planning condition on the estate |
| Rear addition | Flat roof | Deck, upstand, drainage fall |
Stage 02 · Slate and pan
Opening a stone slate roof without losing its look
Stone slates are laid in courses that shrink in size from eaves to ridge, the biggest and heaviest at the bottom. Cut a window through that pattern and the courses have to be rebuilt around the frame, each slate sorted by size and set back where it belongs. If this is done carelessly the new opening reads like a scar. If it is done in order, the unit looks as though it was always there. We plan which slates come off first, and where they are stacked, before the day.
Pantiles pose another puzzle. They roll up and down in a wave, so a flat flashing kit leaves gaps along the troughs. A profiled apron, ordered to the tile, follows the wave and closes the frame side to side. We note the make or the profile at survey and order to match.
Under either covering, the timber in an older roof is seldom regular. Rafters vary in section and spacing, and some have been cut for chimneys in the past. We stretch the tape across the gap at the very point the unit is meant to occupy. Where a rafter would need to be cut, we say so in the plan and say how it is trimmed.
Then there is the angle. Every roof window and conservation rooflight is made for a stated span of pitches, and the steep gables here suit most comfortably. The measured pitch is written down, so that the unit named in your plan is one the slope can really carry.
On stone, the order the slates come off is decided in the kitchen, not on the roof.
Graded stone courses
- Slates shrink in size from eaves upwards
- Lifted, sorted and stacked by size
- Relaid so the pattern runs on unbroken
- Rafters judged for the extra weight
Rolling pantile
- Tiles rise and fall in a regular wave
- Profiled apron ordered to the make
- Troughs closed along both sides of the frame
- A few spare tiles counted before work begins
Stage 03 · The council's say
Who decides, and what they have said before
The planning authority here is South Gloucestershire Council. Marshfield has a conservation area, and a conservation area on its own does not forbid a rooflight: such work can remain permitted development unless the council has removed that freedom with an Article 4 direction. So the useful questions are narrower. What does the direction say, if there is one, and what has the council decided on neighbouring houses? Its website and planning register hold both.
The village also falls within the Cotswolds National Landscape. Reduced permitted development can apply on land of that status, though ordinary rooflights are not simply outlawed. We read what governs your address, put the finding on paper, and recommend a question to the council whenever the picture is unclear. Our planning permission guide holds the permitted development tests, so they are not repeated here.
Marshfield has a high number of listed buildings, and for these the test is different. Work that alters how a listed house looks or feels must first get listed building consent, whatever permitted development might otherwise allow. A flat or a maisonette has no such freedoms to begin with.
Your plan ends this part with one plain verdict. Either there is nothing to apply for, or we would suggest an application, or listing means consent has to be sought first. We check and advise. The council decides.
Questions put to the record for one address
- Is the house inside the conservation boundary line?
- Does an Article 4 direction cover the street?
- Is the building on the statutory list?
- Did the estate consent take away householder rights?
- Does the Cotswolds designation alter the answer?
Stage 04 · Glass up the passage
Bringing glass up to a roof behind a wall
Houses built hard against the pavement leave no front garden and little room for a van. Rear slopes are reached through a side passage, a yard gate or the house, and some plots are walled on every side. The survey walks that route, because the way glass and frames reach the roof shapes the whole schedule far more than the unit itself.
A roof window can usually be lowered into place from the room beneath, so the work outside is mostly flashing, plus slates or tiles closed up beside the frame. If the slope is tall or the access awkward, a scaffold or a tower goes up first, ordered early and noted on the plan. Glass for a flat roof has to be hoisted, so that gets its own check.
A fresh hole in a finished roof counts as building work, so Building Control has a place in the day. If the work is notifiable, the paperwork to Building Control is ours to file. The plan names the body that takes the notice, council or private.
We pin the fitting date down at the moment of ordering. A conservation rooflight or a big glazed unit may be made to order and arrive later than something off the shelf, so your plan lists three dates: the order, the delivery that is due, and the morning of the fitting. By evening, the roof is shut again.
What bends the schedule in Marshfield
| Kerbside space | Parking for the van, and the carry to the house |
|---|---|
| The way through | House, side passage or walled yard to the rear |
| Height of slope | Decides whether a scaffold or tower is booked |
| Stone slate | Relaying takes longer than modern tile |
| Room below | How much lining and finishing the opening needs |
We note every one of these at the visit, and each feeds into the written quote.
Stage 05 · Survey sheet
A morning with a tape in the rafters
The visit starts in the roof void, where we can reach it. A tape runs between the rafters at the planned spot, the timber gets looked over for soundness and old movement, and we record what sits under the covering: battens, felt, or nothing at all. Plenty of old roofs have no underlay at all, and that alters how an opening is made weathertight.
Outside, the covering, the angle and the neighbouring roofs are read, with chimneys and valleys given a wide berth. Once indoors we settle where the daylight should land, for instance over the bedside, the stairs or the bathroom, and whether the unit should open.
Back at base, all of it is turned into your written job plan. It names the unit with its size code, gives the permission finding and the Building Control route, and shows the delivery wait, then the fitting date. Once you accept it, you hold a written ten-year guarantee covering our workmanship.
What leaves with us after the visit
- Rafter gaps measured at the planned spot
- Timber soundness noted
- Covering, pitch and underlay recorded
- Route for glass and frames walked
- Permission finding drafted for the plan
