What do roof lanterns in Warminster involve?
For Warminster 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.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. In Warminster, as anywhere, roof lanterns are the usual choice for rooms that need height as well as light.
Warminster sits about 10 km from Frome and 13 km from Trowbridge, and we cover the whole BA12 postcode district and the roads in between.
Options we can specify in Warminster
- Internal and external colours
- Opening vents with electric control

- Double or triple glazed with solar-control options

What to check first
- Larger lanterns may need a steel or timber ring beam
- Plaster-box depth affects how the lantern looks from below
Planning, building control and Warminster
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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.

Roof lanterns in Warminster: 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.
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.
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.

Yes. We survey and fit roof lanterns in Warminster and across Wiltshire. Send your postcode and we will offer a survey date when we reply.
