Roof lanterns for Winchester: the essentials
We handle roof lanterns across Hampshire, including Winchester. In short: hipped glass lanterns that lift the ceiling of orangeries and extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Roof lanterns suit orangeries, kitchen-diners and single-storey extensions.
We work across Hampshire, including Winchester, and in neighbouring towns such as Eastleigh and Southampton. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Winchester
- LED lighting in the plaster box
- Opening vents with electric control
- Solar-control or self-cleaning glass

Consents for roof lanterns in Winchester
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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 Winchester: questions
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 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 you work alongside my builder in Winchester?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do you fit roof lanterns in Winchester?
Yes. We survey and fit roof lanterns in Winchester and across Hampshire. Send your postcode and we will offer a survey date when we reply.
