Roof windows and rooflights in Barnsley
Roofline supplies and fits pitched roof windows and flat roof lights across Barnsley. New openings cut and trimmed, old units replaced, and every one flashed for the roof covering it sits in so the light comes in and the water stays out.

Fitted by roofers, so the weathering is right
A roof window is a hole in a roof. Whether it leaks depends entirely on the flashing kit around it and how the tiles or slates are dressed back to it. That is roofing, which is why a roof window fitted by a roofer tends to outlast one fitted by a joiner. We fit new windows, replace old and failed units, and put right ones that were fitted badly.
- Pitched roof windows from the main manufacturers, centre-pivot and top-hung
- Flashing kits matched to the roof covering: interlocking tile, plain tile, slate
- New openings cut and trimmed, with rafters doubled where needed
- Replacement of old, misted or leaking roof windows
- Flat glass roof lights and roof lanterns for extensions
- Conservation roof windows for listed buildings and conservation areas
- Blinds, insect screens and remote-opening options


Every job is photographed before and after so you can see exactly what was done.
Roof window problems we fix
Most leaking roof windows are not the window. They are the flashing or the tiles around it.
- Water staining on the plaster around a roof window
- Condensation between the panes (a failed seal)
- The window no longer opens or closes properly
- Rot in the frame or the timber reveal
- Tiles above the window cracked or slipped
- Flashing lifted, patched or sealed with mastic
- Daylight around the frame from inside
- A flat roof light that ponds around its kerb
- A loft or landing that is dark and could be bright
Roof windows and rooflights: your questions
Do I need planning permission for a roof window?
Usually not. Roof windows on a house are generally permitted development provided they do not project more than 150 mm from the roof slope and the house is not listed or in a conservation area with an Article 4 direction. Side-facing windows above ground floor may need obscure glazing. We will tell you if your property is one of the exceptions.
Can you replace an old roof window like-for-like?
Yes. The main manufacturers publish replacement guides so a modern window drops into the opening left by an older model, often with a new flashing kit. It is usually a half-day job and the loft is transformed.
Why is there condensation on my roof window?
Condensation on the inside surface in winter is normal in a humid room and improves with ventilation. Condensation between the two panes means the sealed unit has failed and the glass needs replacing. Roofline can replace the glazing unit or the whole window.
