Rooflight upstands & kerbs for Exeter: the essentials
For Exeter homes and buildings we offer rooflight upstands & kerbs: insulated kerbs built and waterproofed to suit your rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. In Exeter, as anywhere, rooflight upstands & kerbs are the usual choice for new flat-roof openings and rooflight replacements.
Exeter is around 59 km from Plymouth, and we survey and fit throughout that part of Devon, including the EX1 district.

- Timber upstands with insulation
- Internal plaster-box linings

Consents for rooflight upstands & kerbs in Exeter
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. 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.
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. 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.

Common questions
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.
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.
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
Do I need to be at home for the survey in Exeter?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Exeter?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
