📞 Call Now: 01473 807630Velux roof windows and roof lights are a common feature in Ipswich's converted loft spaces, particularly in the Victorian and Edwardian properties around Christchurch Park and the 1930s semis in Rushmere St Andrew and Whitton that have had loft conversions over the decades. They are also fitted in the more modern housing stock where additional light in upper floor rooms is wanted without a full dormer conversion.
The most common issue we deal with on existing roof lights in Ipswich is failed flashing — the weatherproofing collar that seals the window to the surrounding roof surface. Most flashing kits use aluminium or lead that degrades after 15–25 years depending on original specification and exposure. When the flashing fails, water tracks under the surrounding tiles and into the opening, causing ceiling damage and damp that is often first noticed as a mysterious wet patch around the window frame during rain.
For new Velux installations, we survey the roof structure carefully before specifying the window size. The position within the roof slope, the rafter spacing, and the tile or slate profile all affect the choice of window and flashing kit. We handle the structural opening (cutting between or trimming rafters as needed), install the window frame, and fit the correct flashing kit for the roof type — including the correct conservation area units on properties where planning applies.
Several of Ipswich's central and suburban areas have conservation designations. In these areas, roof lights that would alter the character of the roof slope may require planning consent. We check conservation area status and advise on planning before any work starts — including recommending the correct low-profile or conservation-spec window where consent has been granted.

📞 01473 807630Roof windows bring light into loft conversions and top-floor rooms across Ipswich. Whether you're adding one or a leaking old one needs replacing, the watertight detail where the window meets the roof is what matters.
When it is not the answer: If your existing Velux is sound and only the blind or the internal trim is tired, you don't need a new unit — we'll tell you if a simple flashing or seal fix will do. Read the full guide.
Roof windows are increasingly common across Ipswich as loft conversions add bedrooms and studies to the Victorian terraces and 1930s semis. Whether you're adding light to a dark top-floor room or replacing a misted, draughty old skylight, the detail that matters is the flashing kit where the window meets the covering — get that wrong and the window becomes the leak. We size and position the window to the roof pitch and covering, form the opening cleanly, and dress the manufacturer flashing kit into the tiles or slates so the junction is watertight for the life of the window. On the flat-roofed dormers common on Ipswich loft conversions, it's the junction with the main pitched roof that needs the careful leadwork.
The watertight detail is everything with a roof window. We use the manufacturer's own flashing kit — matched to whether your roof is tiled or slated — and dress it into the covering so the junction sheds water for the life of the window, rather than relying on sealant that perishes. The opening is formed cleanly between the rafters, with any trimming done properly so the roof structure stays sound, and we make good inside and out so the finish is neat around the reveal. On the flat-roofed dormers common on Ipswich loft conversions it is the junction between the dormer and the main pitched roof that needs the careful leadwork, and that is exactly where a poorly-detailed dormer starts to leak.
Most Ipswich roof-window work falls into two jobs: adding light to a converted or top-floor room, and replacing an old skylight that has started to leak or mist up. A single window into an existing pitch is typically a day's work; a like-for-like replacement into an existing opening is often quicker. We keep the roof watertight at every stage, so the covering is never left open to the weather, and we make good the reveal inside so the finish around the window is neat. On the terraces and 1930s semis where lofts are commonly converted, we match the flashing kit to the existing tile or slate covering, because a Velux dropped into the wrong flashing kit for the roof type is exactly the installation that leaks a winter later.

We assess the roof pitch, covering and structure to size and position the window and confirm the correct flashing kit.
A fixed price for supply and fit, with any structural or covering work itemised.
Booked within a few days; a single window is usually a one-day job.
We form the opening, fit the window, dress the manufacturer flashing kit into the covering, and make good inside and out.
Site cleared, guarantee handed over.
| Job | Typical duration |
|---|---|
| Single Velux, existing pitch | 1 day |
| Replace like-for-like | Half a day |
| Multiple windows / conversion set | 2–4 days |
| Flashing-only repair | A few hours |
We keep the roof watertight at every stage; heavy rain days are scheduled around for opening-up work.
Roof window work runs from a tower or scaffold for safe standing time and to work the covering around the window. Scaffold is specified for: most installations — safe standing time is needed to dress the flashing into the roof - always itemised in your written quote, never a hidden extra, and we arrange it.
Ipswich's Victorian terraces off Norwich Road are narrow-fronted with resident parking, so rear-access scaffold and permit-controlled pavement space are common; the post-war estates at Chantry and Whitehouse have open frontages where access is far simpler. Pavement scaffold and skip permits go through Ipswich Borough Council; allow a few working days on streets like Fonnereau Road, the terraces off Norwich Road, the California streets where space is tight.
| Job | Typical range | Notes |

Worked example: Supplying and fitting a single Velux into an existing pitch on an Ipswich loft conversion, flashing kit dressed into the tiles: about £1,650.
Staged payments on installations — nothing before the window and materials are on site. VAT included.
Covering IP1, IP2, IP3, IP4, IP5 and surrounding postcodes.
Installation workmanship is covered for 10 years; Velux and other units carry their own manufacturer warranties on the window and flashing kit.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
Some internal dust when the opening is formed — we sheet the room and clear up. One or two days per window, and you can stay in the house. You do not need to stay home for external work - we just need power and access agreed in advance.
We open up and close in the same working window so the roof is never left exposed; wet spells are scheduled around. Ipswich sits exposed to easterly weather off the North Sea with little shelter, and the Gipping valley holds autumn damp that slows drying times.
"Two new Velux windows in our Victorian loft conversion. Conservation area compliant units, correct flashing for the Welsh slate. They checked planning before ordering. Clean installation, no mess."
"Leaking roof light — flashing had completely failed. They replaced the full flashing kit on the survey visit, didn't try to sell a new window when it wasn't needed. Honest and efficient."
"Sealed unit replacement — the glass had been misting for years. They carried the right size on the van, replaced it in under an hour. Looks completely new. Very efficient service."
A standard Velux window supply and fit in Ipswich (tile flashing kit, single unit, standard size) typically costs £600–£950. Larger or non-standard sizes, flat roof windows, and conservation area units cost more. Free survey, exact quote.
Most Velux leaks in Ipswich properties are caused by failed flashing kits rather than the window itself. The lead or aluminium flashing around the window degrades and allows water to track under the tile course around the opening. We assess on a free survey and replace the flashing kit rather than the whole window in most cases.
Standard Velux windows flush with the existing roof slope are permitted development in most cases. Conservation area properties and listed buildings may have restrictions. We check planning status during our survey visit. Roof lights that protrude above the roof line are more likely to require consent.
Yes. If the frame is sound but the sealed unit has failed (misting between panes), we can replace the glass unit without replacing the full window. This is significantly cheaper than a full replacement and restores the thermal performance. We carry common Velux sealed unit sizes.
A correctly installed Velux window should last 20–30+ years. Flashing kits may need attention every 15–20 years depending on original specification and exposure. We carry out free condition assessments on existing roof lights as part of any roof survey.
Yes — Velux installation in Victorian and Edwardian loft conversions across Ipswich is regular work. We ensure the flashing kit is appropriate for the tile type (slate-specific kits for original Welsh slate roofs, clay tile kits for period properties) and check planning compliance.
The window (the frame and glass unit) goes inside the roof structure. The flashing kit is the weatherproofing collar that seals the window to the surrounding tile or slate surface. They fail at different rates — the window typically outlasts the flashing. A leaking roof light in Ipswich is usually a flashing kit replacement, not a full window replacement.
