Rooflight upstands & kerbs for Clacton-on-Sea: the essentials
Rooflight upstands & kerbs in Clacton-on-Sea means insulated kerbs built and waterproofed to suit your rooflight. We cover the CO15 district and the rest of Essex, with a survey before any price is fixed.
In the East of England, bungalows and chalet bungalows with large flat-roofed extensions are common, and they often suit a long run of rooflights. Rooflight upstands & kerbs suit new flat-roof openings and rooflight replacements.
We work across Essex, including Clacton-on-Sea, and in neighbouring towns such as Harwich and Colchester. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for Clacton-on-Sea
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.

Common 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.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
Can you work alongside my builder in Clacton-on-Sea?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Clacton-on-Sea free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
