How we approach pitched roof windows in Caerphilly
Pitched roof windows in Caerphilly means centre-pivot and top-hung skylights for tiled and slate roofs. We cover the CF83 district and the rest of Gwent, with a survey before any price is fixed.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Typical uses for pitched roof windows include lofts, attic rooms, landings and vaulted ceilings.
Caerphilly is around 15 km from Newport, Gwent, and we survey and fit throughout that part of Gwent, including the CF83 district.

Planning, building control and Caerphilly
Planning rules in Wales are tighter than in England for rooflights: Class C rights do not apply in conservation areas, National Parks or AONBs, so a rooflight there needs planning permission. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
Welsh Building Regulations expect new or replacement rooflights to reach 2.2 W/m²K and roof windows 1.4 W/m²K or a Band B rating. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.

Questions about pitched roof windows in Caerphilly
Can you replace an old roof window?
Yes — replacement into the same opening is usually quicker than a new install, often a few hours per window.
Can a roof window be fitted from inside?
In most cases, yes — only the tiles around the opening are lifted, and much of the work is done from inside the loft.
Do I need planning permission for a roof window?
Often not, under householder permitted development, provided it does not project too far above the roof plane and conditions are met. Listed buildings, flats and some conservation areas are different. Our planning guide covers each nation.
Can you work alongside my builder in Caerphilly?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Caerphilly?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
