Rooflight upstands & kerbs in Felixstowe: what is involved?
Thinking about rooflight upstands & kerbs in Felixstowe? The short answer: insulated kerbs built and waterproofed to suit your rooflight. The longer answer depends on your roof, which is why we survey before we price.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. Think of rooflight upstands & kerbs for roofs where the old kerb is low, cold or leaking.
From Felixstowe to Harwich, Ipswich and Clacton-on-Sea, the same survey-first process applies: measure, specify, fix the price, then fit.

Do you need permission in Felixstowe?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.

Questions about rooflight upstands & kerbs in Felixstowe
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
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.
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.
Will I need planning permission in Felixstowe?
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.
How do I book a survey in Felixstowe?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
