How we approach rooflight upstands & kerbs in Welshpool
Rooflight upstands & kerbs in Welshpool means insulated kerbs built and waterproofed to suit your rooflight. We cover the SY21 district and the rest of Powys, with a survey before any price is fixed.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. In Welshpool, as anywhere, rooflight upstands & kerbs are the usual choice for roofs where the old kerb is low, cold or leaking.
Neighbouring towns include Newtown (19 km) and Rhosllannerchrugog (39 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Welshpool
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.
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.
Read the planning permission guide before you commit to a design.

More we do in Welshpool
Rooflight upstands & kerbs in Welshpool: questions
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.
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
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.
Is the survey in Welshpool free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Welshpool?
