What do rooflight upstands & kerbs in Pwllheli involve?
We handle rooflight upstands & kerbs across Gwynedd, including Pwllheli. In short: insulated kerbs built and waterproofed to suit your rooflight. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Think of rooflight upstands & kerbs for roofs where the old kerb is low, cold or leaking.
Pwllheli is around 42 km from Bangor, Gwynedd, and we survey and fit throughout that part of Gwynedd, including the LL53 district.

Do you need permission in Pwllheli?
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. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.

Questions about rooflight upstands & kerbs in Pwllheli
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
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.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
How do I book a survey in Pwllheli?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Is the survey in Pwllheli free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
