Rooflight upstands & kerbs in Penrith: what is involved?
Rooflight upstands & kerbs in Penrith means insulated kerbs built and waterproofed to suit your rooflight. We cover the CA11 district and the rest of Cumbria, with a survey before any price is fixed.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. In Penrith, as anywhere, rooflight upstands & kerbs are the usual choice for new flat-roof openings and rooflight replacements.
Neighbouring towns include Keswick (25 km) and Carlisle (28 km). We offer a survey date when we reply to your enquiry.

Do you need permission in Penrith?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
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.

Yes. We carry out rooflight upstands & kerbs in Penrith and across Cumbria. Send your postcode and we will offer a survey date when we reply.

Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
