Velux roof windows and skylights bring light into Ipswich loft spaces and roof rooms. We fit new Velux windows, replace failed flashings, install sealed unit replacements, and repair leaking roof lights across Ipswich and Suffolk.
Velux 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.

"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.
