Velux Roof Windows in Wantage
Velux Roof Windows Specialists in Wantage
Velux and roof window installations across Wantage properties are a regular part of our work — both fitting new windows during loft conversions or extension works, and repairing or replacing windows where the original flashing kit has failed. Leaking Velux windows are one of the most commonly misdiagnosed roof problems: the tile around the window is often fine, but the factory flashing kit has failed at the upstand junction.
Why Velux Windows Leak
Most Velux leaks across Wantage properties are caused by flashing kit failure rather than damage to the window itself. The original factory flashing kit — which seals between the window frame and the surrounding tiles — deteriorates after 15–25 years. The rubber seals on the upstand degrade, the lead or aluminium flashing separates from the tile, and water tracks into the roof void at the junction. In most cases, replacing the flashing kit resolves the leak without replacing the entire window.
Planning and Building Regulations
Most Velux installations on rear roof slopes are permitted development and do not require planning permission. Front roof slope installations, installations on listed buildings, and windows in conservation areas in Wantage may require prior notification or planning consent. We check for every survey address before ordering any materials.

On Wantage roofs, the repairs that come up most are tied to that stock — slipped tiles and perished mortar on the older frontages around the Market Place and Newbury Street, and wind-lifted or cracked interlocking tile on the estate roofs. We match the fix to what the roof in front of us actually is, rather than reaching for a standard job sheet.

Honest advice
How to Tell You Need Roof Repairs
In Wantage, the roofs we are called to reflect the town's own building character. Wantage, King Alfred's market town, has a Georgian and Victorian core around the Market Place and Newbury Street backed by inter-war and post-war estates climbing towards the Downs — clay tile and slate on the old centre, concrete interlocking on the estates. Wantage sits at the foot of the Downs where the Letcombe Brook runs through, so it catches more wind off the escarpment than the valley towns, and exposed south-facing slopes weather harder.
On Wantage roofs, the repairs that come up most are tied to that stock — slipped tiles and perished mortar on the older frontages around the Market Place and Newbury Street, and wind-lifted or cracked interlocking tile on the estate roofs. We match the fix to what the roof in front of us actually is, rather than reaching for a standard job sheet. The valley and hill geography around Wantage matters here too: where a roof sits determines how fast a small fault turns into an internal leak, so what looks minor on an exposed Wantage slope is worth checking sooner rather than later.
Most Oxford roof problems announce themselves indoors before they are visible outside — a damp patch, a dripping loft, or debris in the gutter. The question is whether it is a contained repair or the first sign of a covering at the end of its life.
A damp patch on an upstairs ceiling that darkens after rain
Daylight or wet timber visible in the loft
Slipped, cracked or missing tiles seen from the ground
Debris from the roof (mortar, tile fragments) in the gutters or on the drive
Staining down a chimney breast or near a valley
When it is not the answer: If more than about a third of the covering has slipped or the whole roof lifts tile-by-tile from nail sickness, repairing piece-by-piece is money wasted — re-roofing is the better long-term value. Read the full guide.

How a Oxford Roof Repairs Job Runs
1. Survey & diagnosis
Every Wantage job follows the same disciplined sequence, adapted to the property — a period roof around the Market Place and Newbury Street gets more survey and matching time than a modern estate roof, but the steps are the same.
We inspect the roof and the loft to find the true source — water often tracks metres from the entry point on Oxford's older long-rafter roofs. No call-out fee.
2. Written itemised quote
You get a fixed-price written quote naming the materials and the exact scope, with scaffold or access itemised, not a vague verbal figure.
3. Scheduling
Scheduled repairs are usually booked within 5–10 working days; active leaks are prioritised for same-day make-safe.
4. The repair
We carry out the repair with matched materials where conservation compliance requires it, and protect the area below.
5. Cleanup & sign-off
We clear all debris, water-test where relevant, and hand over the written 10-year workmanship guarantee.
Wet or high-wind days pause tiling and leadwork — we build weather margin into every Oxford booking and make the roof safe at the end of each day.
Access
Scaffold, Skips & Street Access
Around Wantage Market Place and the Newbury Street frontages, narrow pavements bring permit scaffold and conservation matching; the estates rising towards the Ridgeway are open and driveway-accessible for towers.
Most Oxford repairs run from towers or roof ladders; scaffold is quoted only where the job needs safe standing time at height. Scaffold is specified for: chimney-side repairs, full valley rebuilds, and anything beyond a day working at height - always itemised in your written quote, never a hidden extra, and we arrange it.
Central Oxford's medieval street core and the tight Victorian terraces of Jericho and off the Cowley Road mean rear-access scaffold and permit-controlled pavement space are the norm on many jobs. Pavement scaffold and skip permits go through Oxford City Council; allow a few working days on streets like Holywell Street, Ship Street, St Michael's Street, Merton Street where space is tight.

Worked example: A rear valley rebuild on a 1930s semi in Summertown, including tower access and waste removal, typically runs around £680.
No deposit on repairs under £500. Staged payments on larger jobs — nothing up front before materials are on site. VAT included in every written quote.

On top: manufacturer warranties on materials (terms vary by product).

Good to know
Disruption, Mess & Weather
A day of ladder or tower work and a small amount of tile debris — we sheet below the work area and clear everything before we leave. You do not need to stay home for external work - we just need power and access agreed in advance.
Repairs run year-round; temporary weatherproofing goes on the same day if rain stops work mid-job. The Thames and Cherwell valley setting keeps ambient humidity high, so drying times for mortar, GRP and biocide run longer here than on the surrounding higher ground.

FAQ
Velux Roof Windows Wantage — Common Questions
New Velux installation in Wantage costs £800–£1,400 per window including supply, fit and flashing kit. Flashing kit replacement on an existing window costs £350–£600. Glass replacement costs £400–£700. Free written quotes provided.
Most Velux leaks on Wantage properties are caused by flashing kit failure rather than window damage. The rubber upstand seals and lead or aluminium flashings degrade after 15–25 years. A survey will confirm whether the flashing kit or the window unit itself needs replacement — in most cases, replacing the flashing kit resolves the leak.
Most Velux installations on rear roof slopes are permitted development with no planning permission required. Front-facing installations and windows on listed buildings or in Wantage's conservation areas may need consent. We check requirements at the survey stage before ordering any materials.
Yes. If the window frame and flashing are in good condition but the glass is cracked, fogged or damaged, replacement glass is available for most Velux models and costs £400–£700 fitted. We assess the condition of the frame and flashing at the same visit.
A standard Velux installation in Wantage takes half a day to one full day depending on the tile type and access. Multiple windows are typically done in sequence on the same visit. We confirm the schedule in the written quote.
The flashing kit is the weatherproofing system between the Velux window frame and the surrounding roof tiles. It includes the upstand frame (which sits over the tiles), lead or aluminium cover flashing, and rubber seals at the junction. An incorrectly specified or degraded flashing kit is the most common cause of Velux leaks.
Yes. We install and repair Velux, FAKRO, RoofLITE and other roof window brands. For heritage and conservation area properties in Wantage, we can source slim-profile and conservation-approved units that satisfy planning requirements.
Leaking Velux windows on Wantage properties are among the most frequently misdiagnosed roof problems. In the majority of cases we attend, the cause is flashing kit failure at the junction between the window frame and the surrounding tiles — not the tile itself and not the window unit. Replacing the flashing kit resolves the leak in most cases without touching the window or surrounding tile.
Wantage Tile Profile and Flashing Compatibility
The tile type on your Wantage property determines the correct flashing kit specification. Wantage's Victorian market town core and 1970s–1980s expansion estates properties have a mix of tile profiles — clay plain tile on older properties, concrete interlocking on post-war stock. A flashing kit for the wrong tile profile will not seal correctly regardless of installation quality. We specify the correct kit for the tile type on every Wantage survey.
Planning Requirements in Wantage
Rear slope Velux installations on most Wantage properties are permitted development with no planning notification required. Front slope installations and any window on a conservation area or listed Wantage property require prior notification or planning consent. We check for every Wantage address before ordering materials or confirming installation.
