VELUX Window Installers › Neath › Guide
Adding a roof window to a roof that has been there for decades is a common job, and in Neath there are plenty of lofts with space waiting to be used. It is not a case of cutting a hole and dropping in a window. This guide explains what we check, how the opening is formed, and what to expect.
What we check first
We start in the loft. Rafter spacing, the pitch of the roof, headroom underneath, existing insulation and the condition of the timbers all affect what is possible. Outside, the roof covering decides which flashing kit is needed. If the pitch is very shallow or the roof is in poor condition, we say so before going further.

- Pitch of the roof and headroom beneath the slope
- Roof covering: slate, clay or concrete tile
- Existing insulation and what lies beneath it
Forming the opening
To make room, one or more rafters may need trimming and doubling up to carry the load around the opening. We cut the roof covering back carefully, frame the opening, and fit the window in the correct position in the slope. On slate, we aim to disturb as few slates as possible.
This is why the work cannot be guessed from a catalogue. Rafters on older Victorian roofs are often generous but vary, while post-war roofs may use lighter timber that needs more support. We check on site and explain what the framing will involve.
Flashing, lining and insulation
Each window must be matched to a flashing kit made for the roof covering, whether slate, plain tile or concrete interlocking tile. Inside, the lining, insulation and vapour control around the opening keep the room dry and warm. Most leaks and damp patches trace back to these details rather than to the glass.
Rooms, light and ventilation
A roof window brings in more daylight than a vertical window of the same size and lets you open the room to fresh air. In a Neath terrace the rear pitch is often the best place, keeping the street view unchanged. Position matters: too high and you only see sky, too low and headroom is lost.
On estate houses around Skewen and Briton Ferry the loft may need insulating better before it becomes a living space. We look at the whole picture so the new room is comfortable, not just bright, and we tell you what we would do first.
Permissions and the next step
Some work may need planning or Building Regulations checks — we advise before work starts. Beyond that, the next step is simple: tell us about the house, and we arrange a proper look at the loft and the roof. We then explain the window options, the work involved and what the finished room will be like.

Common Questions
Can any loft take a roof window?
Not every loft. The pitch, the headroom, the rafters and the roof covering all matter. Most ordinary pitched roofs in Neath can take one, but we check on site and say plainly if a particular position will not work.
Will it leak?
A properly matched flashing kit, careful framing and good sealing make a leak unlikely. Most leaks around roof windows trace to flashing, sealing or the surrounding covering, so those details get our full attention.
Does a roof window need blinds?
Many people add a blind to control summer sun and glare, particularly on a south-facing slope. It is a personal choice rather than a necessity, and we can discuss options when we plan the window.
