Velux Roof Window Installation in Wokingham
Roof repairs, re-roofs and flat roof specialists across Wokingham. Free surveys, fixed written quotes, tidy workmanship.
Wokingham Roofing Company supplies and fits Velux roof windows across Wokingham — new installations cut into existing roofs, straight swaps for tired old units, and the flashing work that decides whether a roof window stays watertight for twenty-five years or leaks by Christmas. A roof window is the cheapest transformation in the loft business: one day's work turns a dim loft room or dark landing into the brightest space in the house.
We fit them as roofers, which is the point. The window itself is a factory-made unit; the skill is in the hole — trimming rafters correctly, dressing the flashing kit into your specific tile profile, and making good the underlay around the opening.
Roof window work we do
New installations
Opening formed, rafters trimmed and doubled where needed, window set to the correct height, flashed and finished inside with an insulated plasterboard reveal ready for decorating.
Replacement windows
Failed double glazing, rotten sashes or pre-1990s units swapped for current Velux models — usually a same-size swap using the existing opening, done in half a day.
Flashing kits matched to the roof
Velux's EDW kits suit profiled tiles, EDL for slate, and recessed kits sit the window lower for a sleeker line. The wrong kit is the number one cause of leaking roof windows.
Blinds and controls
Blackout, thermal and venetian blinds fitted to existing windows, plus solar and electric opening for out-of-reach units — no wiring needed for solar.

What decides a good installation
Three details separate a dry roof window from a problem one. First, the flashing kit must match the roof covering exactly — profile depth matters, and forcing a tile kit onto slate is a leak in waiting. Second, the underlay needs a proper collar around the opening with a drainage gutter above the frame, so any water that ever gets under the tiles is shepherded around the window rather than into it. Third, the insulation collar and vapour barrier stop the warm loft air condensing inside the reveal — the 'leak' that turns out to be condensation is the most common roof window complaint of all.
Windows sized and positioned right also need no planning permission on most Wokingham houses — roof windows fall under permitted development provided they don't project more than 150mm, though conservation areas have tighter rules we'll flag at survey.
