Market town roofs
Georgian fronts, canal terraces and flats above shops
Devizes grew around a medieval castle and a great market place, and it kept growing when the Kennet and Avon Canal brought trade, with brewing growing up alongside it. The result is a Wiltshire market town with a very large historic centre and a conservation area to match, where almost every street holds a different type of roof.
Stage 01 · Street by street
From the Market Place to the canal wharf
In the centre, around the Market Place and the main streets running off it, the buildings are mostly Georgian and Victorian brick, with older timber-framed structures hidden behind some of the fronts. Roofs here are clay tile or slate, often pitched steeply, and the rear ranges that face yards and passages are where nearly all rooflight work happens.
Down towards the canal and the brewery the character shifts to terraces and workers' cottages from the nineteenth century. These are brick houses with slate roofs, regular rafters and small back extensions. Loft conversions are common in this kind of house, and a roof window on the back pitch is the standard way to bring light and headroom into a new room.
Beyond the old town, the twentieth century added interwar semis and postwar estates, with concrete-tiled roofs and, in many cases, flat-roofed extensions at the back. Kitchen extensions at the back often call for a lantern or flat rooflight, and those jobs turn on kerb heights and the fall of the deck.
Because Devizes holds all of this within a short drive, the survey records the building type before anything else, and the rest of the plan follows from it.
| Building | Roof | First look |
|---|---|---|
| Georgian town house | Tile or slate, steeply pitched | Listing status, conservation boundary |
| Canal-side terrace | Slate, regular rafters | Rear pitch, loft height |
| Flat above a shop | Mixed, often flat | Ownership, lease and consent |
| Interwar or postwar house | Concrete tile | Pitch, extension roof |
Stage 02 · Protected centre
What the conservation area means for a front slope
Devizes answers to Wiltshire Council on planning, and a big share of the historic centre sits in the conservation area. Sitting in that area does not stop a house using permitted development for a rooflight, except where a direction takes the right away. The extent is on the council's conservation pages, and any direction is recorded in its register.
Which slope carries the unit is the first design decision. A Georgian front pitch is seen from the street every day, while a rear pitch over a yard is seen by almost nobody, and the difference in how a council reads the two is often large. Where the room can be lit from the back, that is the simpler route. Where the front is the only option, the frame, the bar and the finish all matter more.
Many councils prefer flush, slim-framed rooflights on slopes that can be seen from the street, and the planning officer's view on the front pitch of a Georgian house is likely to be stricter than on the back. The practical advice is simple: put the unit on the rear slope where one will do, and ask first if the front is wanted. The details of those limits are in our guide to rooflight permissions.
Listed buildings are everywhere in Devizes. Where one is involved, any change to its character calls for listed building consent, and no permitted development argument gets around it. We establish the listing, outline what an application would involve and set the outcome down in the plan; the council makes the ruling.
Beyond the town edge the land rises towards the North Wessex Downs. Designation can reduce some permitted development rights, though it does not forbid rooflights, and addresses near the boundary are put to the council.

Stage 03 · Flats and shops
When the roof is shared or the house is a flat
Devizes has plenty of buildings that have been divided: shops with flats above, large old houses turned into apartments and rows of cottages knocked together. Householder permitted development does not reach a flat or maisonette, which means a rooflight there calls for an application in its own right, and the roof itself may belong to someone else.
The first questions are therefore about ownership and permission, not about glass. Who owns the roof, what does the lease say, and is the freeholder's consent needed before anything is cut? We note these on the survey and ask you to clarify them early, because they decide the date as much as the lead time of the unit does.
Where the roof is a flat one over a rear shop or an extension, the work is different again. The kerb, the deck and the way water leaves the roof all need to be understood, and the unit is chosen to sit on a proper upstand. A flat rooflight or a fixed lantern often suits these roofs best.
Shared walls and shared drains complicate matters, so the plan lists any neighbour who needs to know about the work.
House with its own roof
- Householder rights may apply
- Owner decides the unit and position
- Planning search for the one address
- Neighbours told only about scaffold
Flat or divided building
- No householder rights at all
- Lease and freeholder consent checked
- An application of its own is likely
- Shared walls and drains noted
Stage 04 · Getting up there
Narrow streets, yards and market days
A fitting in the middle of Devizes is as much a logistics exercise as a building one. Streets are narrow, market days fill the centre with stalls and traffic, and many properties have no front access at all except across the pavement. The survey asks where the vehicle can stand, for how long, and whether a permit or a polite word with a neighbour is called for.
Rear yards and passages are often the only route to the roof. A roof window can be carried through the house, but a long lantern frame or large glass panel cannot be taken up a Georgian staircase, so those jobs need either a clear yard or a lifting plan. Where scaffold has to stand on the highway or across a neighbour's land, it is arranged in advance and shown in the plan.
Building Control sits in this sequence as well. Any new opening cut into the roof is controlled work. A notifiable job gets its notice filed by us, and the plan then says which body receives it: Wiltshire's building control section or an independent registered approver. Replacing nothing but the sealed glazing needs no notice, and the plan says which category the job falls in.
Once the roof is open it does not stay open. The team closes up the covering and leaves the opening ready for the plasterer, and the date for the fit is nailed down at the point of ordering.
What decides a Devizes fitting day
| Parking and permits | Where the van stands, for how long and with whose agreement |
|---|---|
| Yard or passage access | How glass and frames reach the rear of the building |
| Scaffold position | On the pavement, in a yard or on a neighbour's land |
| Unit size | Large lanterns need a planned lift, small windows do not |
| Covering | Slate and old clay tile take longer to dress back |
We log each of these on the visit, and the quote reflects them.
Stage 05 · The plan
One document before one order
A Devizes survey ends with a single written plan. It identifies the unit by size code, reports the council search, sets out the Building Control route, gives the order's lead time and fixes the fitting day. If a consent is still to be obtained, the plan marks the date as conditional and says why.
Lead time depends on the product. A stock roof window is usually the quickest to arrive, while a lantern or a conservation rooflight is made to order and takes longer, so the plan gives the dates for ordering and delivery next to the fitting day. Asking for the plan early costs nothing and saves waiting later.
Nothing is ordered until you have read it and agreed. If something in the plan is wrong, for instance a measurement or the room you meant, it is corrected on paper first, long before anything is made to measure.
After sign-off the workmanship is guaranteed for 10 years, and you keep the plan as the record of what was fitted and why.
Corrections are made on paper, long before glass is cut.
