What do rooflight upstands & kerbs in Cardigan involve?
Rooflight upstands & kerbs in Cardigan means insulated kerbs built and waterproofed to suit your rooflight. We cover the SA43 district and the rest of Dyfed, with a survey before any price is fixed.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Rooflight upstands & kerbs suit roofs where the old kerb is low, cold or leaking.
Cardigan sits about 35 km from Carmarthen and 38 km from Haverfordwest, and we cover the whole SA43 postcode district and the roads in between.

Consents for rooflight upstands & kerbs in Cardigan
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. 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.
In Wales the limiting values are 2.2 W/m²K for a rooflight and 1.4 W/m²K (or WER Band B) for a roof window in an existing house. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about rooflight upstands & kerbs in Cardigan
How high should a rooflight upstand be?
High enough to meet the rooflight manufacturer's minimum above the finished roof surface — commonly 150 mm. On roofs with deep finishes, such as green roofs, it needs to be taller.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
Can I build the upstand myself?
Your builder can, to our drawing. We check it before the rooflight is fitted, because the unit must sit square and level.
Will I need planning permission in Cardigan?
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.
Do I need to be at home for the survey in Cardigan?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
