Roof lanterns in Rottingdean: what is involved?
Thinking about roof lanterns in Rottingdean? The short answer: hipped glass lanterns that lift the ceiling of orangeries and extensions. The longer answer depends on your roof, which is why we survey before we price.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Typical uses for roof lanterns include orangeries, kitchen-diners and single-storey extensions.
Rottingdean is around 6 km from Brighton, and we survey and fit throughout that part of East Sussex, including the BN2 district.
What you can choose
- Internal and external colours
- Aluminium or uPVC systems
- Rectangular, square or bespoke sizes
- Solar-control or self-cleaning glass
- LED lighting in the plaster box
- Can include opening vents
- Adds visual height to a single-storey room
What to check first
- Needs a strong, level kerb or upstand
- Plaster-box depth affects how the lantern looks from below
Planning, building control and Rottingdean
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. 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.

Roof lanterns in Rottingdean: questions
Do they leak?
Modern lanterns are sealed systems. Leaks usually trace back to the kerb or roof membrane detail, which we form and check ourselves.
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
Roof lantern or flat rooflight?
A lantern adds height and sky from all sides; a flat rooflight is lower-profile and cleaner from outside. Our guide compares them in detail.
Will I need planning permission in Rottingdean?
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.
Is the survey in Rottingdean free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
