Velux windows and roof skylights are one of the most common addition requests on Salisbury's growing stock of loft conversions. The city's large Victorian and Edwardian terraces in Fisherton and St Paul's convert well — deep pitch, good head height, and rear-elevation windows that typically fall within permitted development on non-listed properties. Bishopdown's 1960s bungalow stock is another prime candidate: flat-ceilinged rooms that gain enormous benefit from roof glazing.
Conservation area and listed building constraints complicate matters on properties in and around the Cathedral Close. Front-elevation roof windows require planning permission in these designations, and in some cases the local authority will resist any glazing on visible roof slopes. We advise on this before quoting, not after.
Conservation area properties: rear-elevation windows on a non-listed property are generally permitted development. Front elevation and listed buildings require pre-application advice from Wiltshire Council. We can advise on the likely outcome based on your specific property and location before you commit to a quote.

Rooflights leak at the flashing kit, not usually the glass — so a leaking Velux is often a fitting or flashing problem rather than a faulty window.
When it is not the answer: A leaking rooflight often needs only a new flashing kit, not a whole new window — we'll check before quoting a replacement. Read the full guide.
Rooflights turn up all over Salisbury — loft conversions across the post-war estates in Bishopdown and Harnham, and light wells added to the dark upper floors of the Victorian terraces off Fisherton and Milford. The recurring call is a leak that homeowners assume means a failed window, when it's almost always the flashing kit or the way the unit meets the surrounding tiles or slates. On the older clay-tile and slate roofs in the conservation areas, integrating a rooflight neatly with the covering and underlay takes proper detailing, not a bead of silicone. Whether it's a new flashing kit, a like-for-like swap or a fresh install to bring light into a loft, getting that junction right is what keeps it dry.
We check the window, the flashing kit and the surrounding tiles or slates.
Itemised quote for a new flashing kit, a like-for-like swap, or a new install.
Usually a single day per rooflight.
We fit the window and manufacturer flashing kit, integrating it with the covering and underlay so it's fully weathertight.
Internal reveal made good if agreed, site cleared, guarantee handed over.
| Job | Typical duration |
|---|---|
| New flashing kit only | Half a day |
| Like-for-like replacement | 1 day |
| New rooflight install | 1–2 days |
| Multiple rooflights | 2–3 days |
We keep the opening covered and weathertight at all times; heavy rain can pause a mid-swap.
Rooflight work runs from scaffold or a tower for safe access to the slope. Scaffold is specified for: new installs, multiple units, or steep slopes - always itemised in your written quote, never a hidden extra, and we arrange it.
Salisbury's dense Victorian terraces off Fisherton and Milford mean rear-access scaffold and permit-controlled pavement space, while the post-war Bemerton Heath and Bishopdown estates give easier access but ageing concrete-tile roofs. Pavement scaffold and skip permits go through Wiltshire Council; allow a few working days on streets like Fisherton Street, Milford Street where space is tight.

Worked example: A like-for-like Velux replacement on a loft in Salisbury: around £650 including window and flashing kit.
No deposit on repairs under £500; staged payments on larger jobs with nothing up front before materials are on site. Repairs are standard-rated; a full re-roof usually attracts 5% VAT.
Covering SP1, SP2 and surrounding postcodes.
Velux and other branded units carry manufacturer warranties; our fitting is guaranteed for up to 10 years.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
Some internal access needed and a little plaster make-good on new installs; external work is quick and tidy. You do not need to stay home for external work - we just need power and access agreed in advance.
We plan installs around dry windows and never leave an opening exposed. Salisbury sits where five rivers meet, so valley-floor humidity accelerates moss and slows drying, while higher ground catches wind-driven rain.
"Two Velux windows in the loft conversion — MK06 opening units. Clean installation, flashings integrated properly, no leaks through the first winter. Good communication throughout."
"Leaking Velux in the back bedroom — previous firm said we needed a new window. These lads replaced the flashing kit only and sorted it for a quarter of the price. Should have called them first."
"Roof lantern over the kitchen extension — excellent quality installation, properly integrated into the flat roof system. No issues after 18 months. Very pleased."
Velux window installation in Salisbury typically costs £600-£1,400 per window including roof integration, flashing kit and internal finishing. Roof lanterns and fixed skylights cost more depending on size. We quote individually after assessing the roof structure.
Permitted development rights for roof windows are restricted in Salisbury's conservation areas. Front-elevation roof windows typically require planning permission. Rear-elevation windows on most properties can be installed under permitted development. We advise on what consent is required before quoting.
Yes. Velux leaks are almost always a flashing failure rather than a window failure — the original EDW or BDX flashing kit has failed at the upstand or the lead apron has lifted. We repair and replace Velux flashings without replacing the window itself in most cases.
MK04 (78x98cm) and MK06 (78x118cm) are the most common sizes in 3 and 4-bed Salisbury properties. CK02 (55x78cm) is common in smaller bedroom lofts. We carry most standard sizes and can usually install within a week of confirmation.
Most Velux installations on rear and side roof slopes fall within permitted development and do not require planning permission, provided the window does not project more than 150mm from the roof slope and sits below the ridge height. Conservation area properties and listed buildings have additional restrictions — on listed buildings, any alteration requires listed building consent. We check the planning position for your specific property before any installation is confirmed.
The EDW (Extendable Drainage Window) flashing is the standard Velux supplied flashing kit for pitched tile roofs. It uses a flexible aluminium apron at the bottom and side soakers with a top flashing. Failures are almost always at the apron-to-tile junction or at the side soaker top edge where movement has broken the seal. In Salisbury's exposed positions — particularly properties on high ground or facing south-west — UV degradation and thermal cycling shorten the EDW service life to 10-15 years. Replacement using the correct BDX or BFX flashing is a half-day job per window.
Velux windows can be installed in conservation areas with prior approval — conservation area consent is required for any works that alter the external appearance of a dwelling. Roof lights that sit flush with the roof slope and use conservation-specification units (such as the Velux conservation range with slim sight lines) are generally viewed more favourably. We advise on the planning position, specify the correct unit and handle the installation to conservation area standards.
