Velux & Skylight Installation in Winchester

The single detail that decides whether a roof window stays watertight is the flashing kit. A Velux or skylight must use the flashing kit made for the specific tile profile on your Winchester roof — a generic kit cut to fit is the commonest cause of leaks, working in dry weather and failing in wind-driven rain.

Roof windows, rooflights and dormers

Pitched-roof windows (Velux and equivalent) are the standard for loft rooms. Flat-roof rooflights bring light into extensions and single-storey rear rooms. Dormer windows add both light and headroom but are a bigger job, with cheek flashing and a small flat roof of their own. We fit all three across Winchester.

Structural trimming

Where an opening spans more than one rafter, a structural trimming header carries the load around it. This is proper structural work with correctly sized timber and joist hangers — confirmed at survey and included in the quote.

Positioning for light and ventilation

The position of a roof window changes how well it works. A north-facing window gives even, constant daylight ideal for a home office; a south-facing one floods the room but needs a blind for summer heat. Two windows on opposite pitches give cross-ventilation that clears a stuffy loft room far better than one. We advise on positioning at survey, not just installation.

The building-regulations angle

A habitable Winchester loft room needs a glazed area of at least one-twentieth of its floor area, and if the room is a means of escape, the window must meet minimum opening dimensions for egress. These are not optional details — they are the difference between a compliant conversion and one that fails building control. We size and position the windows to satisfy both the daylight and the escape requirements.

Flashing is everything on a Winchester period roof

The single most important detail on a Winchester roof window is the flashing kit, and it must match the exact tile or slate profile. On the city's clay plain tile and natural slate stock, a generic flashing kit cut to fit is the commonest cause of a window that leaks after its first winter. We use the manufacturer's tile-specific kit every time, which is what keeps the installation watertight for the life of the roof.

Conservation and planning

In Winchester's conservation areas, roof windows on rear slopes within permitted-development limits are generally acceptable, but front-facing rooflights and anything on a listed building need consent. Getting this right before installation avoids the worst outcome: a beautiful new window that the conservation officer requires you to remove. We check the planning position before any work is booked.

We fit roof windows, skylights and flat-roof rooflights across Winchester and the surrounding area, from loft conversions in the period stock of Weeke and Fulflood to contemporary extension rooflights in Eastleigh, Chandler's Ford and the villages.

Every installation uses the manufacturer's tile-specific flashing kit matched to your exact roof covering — the detail that keeps the window watertight for the life of the roof — and includes any structural trimming the opening requires. We confirm the building-regulations position for habitable rooms and the planning position for conservation-area and listed properties before work begins.

Each roof window carries the manufacturer warranty plus our 10-year workmanship guarantee on the installation and flashing. Call 01962 809171 for a free survey and written quote.
