Velux, Dormers & Roof Windows in Twickenham & Richmond

Light, space and a watertight finish

A roof window brings light into a dark loft. A dormer goes further, turning dead roof space into a proper room. Both jobs sound simple, but the roofing has to be spot-on. The flashings, cheeks and weatherproofing are where a badly fitted roof light or dormer starts to leak.

A poorly dressed opening is the most common cause of a leak here. That's why we fit Velux-style windows into the roof slope with care. We also build the roofing side of dormers and loft conversions — the cheeks, the flashings, the weatherproofing. Everything gets dressed in properly, so it stays dry for the long term.

A dormer changes more than the inside of your loft. It also changes the shape of your roof from the street, so the finish needs to match the rest of the house. We choose materials and details that suit a period property, rather than a flat, modern box stuck on the back. Small choices, like matching cladding or tile hanging, make a real difference to how it looks from the street.

Most roof windows fitted into an existing slope don't need planning permission, since they count as permitted development. A dormer is a bigger step, especially on a front-facing roof or inside a conservation area. We'll flag anything you need to check early, so there are no surprises once work starts. We can point you toward the council's own guidance if you want to check the detail yourself.
