Roof lanterns in St Ives: what is involved?
For St Ives homes and buildings we offer roof lanterns: hipped glass lanterns that lift the ceiling of orangeries and extensions. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
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. Roof lanterns suit orangeries, kitchen-diners and single-storey extensions.
We work across Cambridgeshire, including St Ives, and in neighbouring towns such as Huntingdon and St Neots. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Opening vents with electric control
- Internal and external colours
- Aluminium or uPVC systems
- Solar-control or self-cleaning glass
- LED lighting in the plaster box
- Classic look that suits period and modern homes
- Light from every angle across the day
What to check first
- Larger lanterns may need a steel or timber ring beam
- Some designs project above the roof enough to affect planning on certain houses
Planning, building control and St Ives
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.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Roof lanterns in St Ives: 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.
Can a lantern go on an existing extension?
Yes, if the flat roof structure can be opened up and trimmed. We check joists and the roof build-up at survey.
Do roof lanterns get hot?
They can in summer if clear glass is used on a south-facing roof. Solar-control glass and an opening vent make a big difference.
Do I need to be at home for the survey in St Ives?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Do you fit roof lanterns in St Ives?
Yes. We survey and fit roof lanterns in St Ives and across Cambridgeshire. Send your postcode and we will offer a survey date when we reply.
