Roof Windows Fitted Properly in Aberdare
A well-placed roof window transforms the dark middle rooms and attic spaces so common in valley terraces. The difference between a skylight that delights and one that drips is entirely in the fitting - the flashing, the weatherproofing and how the slates are dressed around it.
That is roofing work, not joinery. Aberdare weather will find any shortcut around a roof window within a winter, which is why ours are flashed and detailed by people who spend every day keeping water out of roofs.
We fit leading-brand roof windows into slate and tile roofs, replace failed and leaking units, and detail every installation to handle valley rain. Another part of the complete service from your local Aberdare roofer.

Frequently Asked Questions
Straight answers about skylights and roof windows in Aberdare.
Do I need planning permission for a skylight in Aberdare?
Usually not – most roof windows fall under permitted development. Conservation areas and listed buildings have extra rules, and we will check and advise before any work starts.
How long does fitting a roof window take?
A straightforward single window is normally fitted and fully weathered-in within a day. Structural openings or multiple windows take longer – we will give you a clear programme with the quote.
Can you fit skylights into a slate roof?
Yes – slate is our home turf. The right flashing kit and careful hand-dressing of the slates around the frame make the difference between neat and leaky.
My skylight leaks - do I need a whole new window?
Not always. If the glazing and frame are sound, reflashing and resealing usually cures it for a fraction of the cost. If the sealed unit has failed, replacement is the better spend – we quote honestly either way.
Which brands do you fit?
We supply and fit the leading roof window brands and will recommend the right unit and glazing spec for your room, roof pitch and budget rather than pushing one make.
Which areas do you cover?
Aberdare and the whole Cynon Valley – Aberaman, Cwmbach, Trecynon, Llwydcoed, Cwmdare, Penywaun and Hirwaun.
