VELUX Window Installers › Aberdare
A roof window can turn a dark, unused loft in an Aberdare terrace into a bright bedroom, study or storage space. The window itself is the easy part. What decides whether it stays dry for the life of the roof is the flashing, the framing and the way the opening is finished.
We install VELUX and similar roof windows across Aberdare, Trecynon, Cwmbach, Mountain Ash and Hirwaun. Each job starts with a look at your roof covering and your rafters, so the window, flashing kit and lining are matched properly before anything is cut. Nothing is ordered until that is confirmed.

Roof Windows in Valley Houses
Aberdare's Victorian and Edwardian terraces were built with steep roofs and deep lofts, which makes them good candidates for conversion. The pitch is usually generous, and the loft often runs the full length of the house, so a roof window can light the space without much structural fuss. Houses at the end of a row may also have a side wall to light.
The covering matters a great deal. Many older roofs here are natural or imitation slate, and others have been re-covered in concrete tiles. Each needs a flashing kit made for that profile, and getting that wrong is the commonest reason a window leaks in a wet valley climate. We identify the covering before we order a single part.
Rain in this part of the Cynon Valley is heavy and frequent, and wind drives it sideways up the slopes. That means every junction around the opening has to shed water properly, and the insulation and vapour control inside have to stop condensation forming on cold timber. Getting that detail right matters far more than the brand on the frame.
Roof Window Work We Do in Aberdare
- New roof windows in existing roofs — We cut the opening, trim and double up the rafters where needed, and fit the window with the correct flashing for the covering.
- Loft conversion roof windows — For loft rooms in terraces and semis we position windows for light and headroom, and fit linings and insulation so the room is comfortable.
- Replacing an old roof window — Where an older window is leaking or has misted, we remove it and refit a new one, renewing the flashing and checking the surrounding covering.
- Flashing and weathering renewals — If the glass is fine but water is getting in, we renew the flashing and surrounding sealing, and check the tiles or slates around the frame.
- Lining, insulation and finishing — The opening is lined and insulated, and a vapour control layer is fitted, so the inside is neat and the timbers stay dry.
- Misted and failed sealed units — Misting between the panes means the sealed unit has failed. We explain whether the unit can be replaced or the whole window should be changed.
How We Approach a Window Job Here
Before quoting we look at the roof covering from the ground and the rafters from inside the loft. Spacing, condition and any existing joists decide whether the opening needs trimming. We confirm the size and position with you, so the window lands where you actually want it, not just where it fits.
A roof window may need planning or Building Regulations checks, and we advise before work starts. On the day we protect the rooms below, keep the roof open for as short a time as we can, and finish the lining inside so the room is usable when we leave.
VELUX Window Installers Guides for Aberdare
VELUX Window Installers in Aberdare — Common Questions
Can you fit a VELUX window in an Aberdare terrace loft?
Usually yes. Most terraces have enough pitch and loft depth. We check the rafters and the covering from the loft and the ground, confirm the best position with you, and tell you if anything needs strengthening before we cut an opening.
Does the window need a special flashing for my roof?
Yes. Flashing kits are made for different coverings, such as slate, plain tile or profiled concrete tile. We identify the covering on your roof and fit the matching kit, because the wrong one is a leading cause of leaks around roof windows.
Why is my existing roof window leaking?
Most leaks come from the flashing, the sealing, condensation or the roof covering around the frame rather than the glass. We look at all of those before suggesting a fix, so you do not pay to replace a window that is not the problem.
Will fitting a roof window mean cutting the rafters?
Sometimes. A rafter may need trimming, with the cut ends supported by doubled timbers. We check the loft first and explain what the opening involves, so you know what is being done to the structure before work begins.
What does it mean if my window has misted up?
Mist or droplets between the panes means the sealed glass unit has failed. That is separate from a leak. We can tell you whether the unit can be swapped or whether the whole window should be replaced, depending on its age and fit.
