Velux roof windows and flat roof skylights in Folkestone. Loft conversions across the Cheriton and Folkestone West estates are increasingly adding roof windows.

Velux and skylight work in Folkestone has to be weathertight against the coast. A rooflight is a hole in the roof, and on the exposed seafront the flashing kit and the seal take the full force of wind-driven Channel rain — so a Folkestone rooflight job lives or dies on the quality of the flashing and the fit.
The signs a Folkestone roof needs attention are familiar enough: you are converting a loft or extending and want natural light; an existing rooflight that has started to leak around the frame; a tired or single-glazed skylight you want upgraded for insulation.
On Folkestone's coastal roofs, watch for an existing skylight leaking around the frame after gales, condensation or draughts from a tired single-glazed unit, and any rooflight fitted without the correct flashing kit. On the seafront, the flashing is everything, so a leaking unit is worth re-flashing properly before more water gets in.
The judgement that matters in Folkestone rooflight work is getting the flashing watertight against coastal wind — and, first, whether an existing unit needs re-flashing or replacing.
When it is not needed: If an existing Velux is sound and only the flashing has failed, a re-flash is far cheaper than a full replacement - we will fix rather than replace where sensible. More on repair versus replacement.
On Folkestone's coastal properties around Sandgate Road, rooflight work means new and replacement Velux units, flat-roof rooflights on extensions, and re-flashing leaking existing skylights. The exposure drives wind and rain hard against the frame and flashing, so a poorly-fitted rooflight leaks quickly. We fit the correct Velux flashing kit for the roof covering, seal the frame properly, and detail the upstands robustly for the coastal exposure.
A recent Sandgate Road job fixed a classic coastal leak: an existing skylight fitted with the wrong flashing kit, letting wind-driven rain in every gale. We stripped it, re-flashed with the correct kit for the covering, and sealed the frame robustly for the exposure — watertight through every storm since.
We work Folkestone every week, so a rooflight here is fitted by a roofer who knows Sandgate Road, Cheriton Road, The Old High Street and the local roofs first-hand — the right unit and flashing for the roofs and setting on these streets, not a one-size approach.

On Folkestone's coastal properties around Sandgate Road, rooflight work means new and replacement Velux units, flat-roof rooflights on extensions, and re-flashing leaking existing skylights. The exposure drives wind and rain hard against the frame and flashing, so a poorly-fitted rooflight leaks quickly. We fit the correct Velux flashing kit for the roof covering, seal the frame properly, and detail the upstands robustly for the coastal exposure.
A Folkestone rooflight is only as good as its flashing against the coast, because wind-driven Channel rain will find any gap in the seal or the flashing detail. A unit fitted without the correct kit, or sealed carelessly, leaks within months on the exposed seafront. We use the right flashing kit for the specific covering, seal and detail the frame and upstands robustly for the exposure, and re-flash leaking units properly rather than patching them. The result is natural light that stays watertight in a Channel gale — a rooflight fitted for the coast, not for a sheltered inland roof where the flashing hardly gets tested.
We assess the roof, the rooflight position, and the coastal exposure — on Folkestone roofs the wind and driven rain dictate the flashing and sealing specification.
You get an itemised quote specifying the correct Velux flashing kit for your covering, robust upstand detailing, and coastal sealing, priced clearly.
