Professional VELUX Window Installation in Bristol

Roof windows let natural light into loft spaces and upper floors that would otherwise rely on artificial lighting alone. Fitting them correctly means working through the roof covering itself, so the surrounding flashing and weatherproofing has to be right from the outset.

Brunel Roofing Bristol supplies and fits VELUX roof windows across Bristol, covering new installations, replacements of old or leaking units, and roof windows fitted as part of loft conversions.

Flashing and Weatherproofing

A roof window is only as watertight as the flashing fitted around it. The flashing kit forms the seal between the window frame and the surrounding roof covering, and it has to be matched to the roof pitch, the covering material and the specific VELUX model being fitted.

Most roof window leaks trace back to flashing that has been fitted incorrectly, has deteriorated over time, or was never suited to the roof it was installed on. Getting this right at installation avoids repeat callouts and water damage to the loft space below.

We fit manufacturer flashing kits to VELUX's specification and check the surrounding tiles, slates or felt for a proper weathertight finish before completing the job.

Centre-Pivot or Top-Hung: Which Roof Window Suits Your Project

VELUX windows are available in a range of opening styles, but most domestic installations come down to a choice between centre-pivot and top-hung models. Centre-pivot windows rotate around a fixing at the midpoint of the frame, which makes them straightforward to clean from inside and generally the more cost-effective option. They suit roofs with a reasonable pitch and windows fitted at a height where the handle at the top of the sash is still easy to reach.

Top-hung windows open outward from a hinge at the top of the frame, giving an unobstructed view and more headroom when the window is open, which makes them a common choice for loft conversions where the window sits lower down a room or within easy reach. They also tend to suit lower-pitched roofs better than centre-pivot models. Which one is right for a particular room usually depends on the roof pitch, the window's height from the floor and how the room will be used, and we can talk through the options during a site visit.

VELUX Windows for Loft Conversions

Roof windows are often the main source of natural light in a loft conversion, and they need to be planned alongside the rest of the roof structure rather than fitted as an afterthought. This includes positioning windows to suit the finished room layout, selecting a size and opening style appropriate for the space, and coordinating the installation with any structural work already underway.

Costs vary depending on the window size, the opening mechanism chosen, roof access and whether existing roof coverings need to be matched or replaced around the new window. As a very rough guide, a straightforward single VELUX installation on an accessible roof might run from around £600 to £1,200 including the flashing kit, with electric or solar-powered models and more complex roofs costing more.
