Skylight replacement for Aberdare: the essentials
Thinking about skylight replacement in Aberdare? The short answer: replacing tired domes and failed glass with a modern rooflight. The longer answer depends on your roof, which is why we survey before we price.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Skylight replacement suits older extensions due a modern rooflight.
Aberdare sits about 6 km from Rhondda and 6 km from Merthyr Tydfil, and we cover the whole CF44 postcode district and the roads in between.
What you can choose

Things we check at survey
- A replacement is a chance to meet current thermal standards
- Old glass and domes are disposed of responsibly
Do you need permission in Aberdare?
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
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. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.
