What do roof lanterns in Crowthorne involve?
For Crowthorne 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. In Crowthorne, as anywhere, roof lanterns are the usual choice for orangeries, kitchen-diners and single-storey extensions.
Neighbouring towns include Sandhurst (3 km) and Yateley (4 km). We offer a survey date when we reply to your enquiry.
What you can choose
- LED lighting in the plaster box
- Opening vents with electric control
- Aluminium or uPVC systems
- Solar-control or self-cleaning glass
- Internal and external colours
- Adds visual height to a single-storey room
- Light from every angle across the day
What to check first
- Larger lanterns may need a steel or timber ring beam
- Needs a strong, level kerb or upstand
Consents for roof lanterns in Crowthorne
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 roof lanterns in Crowthorne
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
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.
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.
Do I need to be at home for the survey in Crowthorne?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Crowthorne free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
