How we approach roof lanterns in Witham
Thinking about roof lanterns in Witham? 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.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. In Witham, as anywhere, roof lanterns are the usual choice for orangeries, kitchen-diners and single-storey extensions.
Jobs in Witham are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Choices for your Witham project
- Aluminium or uPVC systems
- Opening vents with electric control
- Internal and external colours
- LED lighting in the plaster box
- Solar-control or self-cleaning glass
- Adds visual height to a single-storey room

Things we check at survey
- Plaster-box depth affects how the lantern looks from below
- Needs a strong, level kerb or upstand
Do you need permission in Witham?
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. 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 Witham: 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.
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.
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 Witham?
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.
Can you work alongside my builder in Witham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
