Roof lanterns for Dunoon: the essentials
Thinking about roof lanterns in Dunoon? 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.
Many Scottish homes have dormers and attic rooms where an extra roof window adds light without a full dormer. In Dunoon, as anywhere, roof lanterns are the usual choice for rooms that need height as well as light.
Jobs in Dunoon 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.
Specification options
- Internal and external colours
- Rectangular, square or bespoke sizes
- Solar-control or self-cleaning glass
- LED lighting in the plaster box
- Aluminium or uPVC systems
- Light from every angle across the day
- Slim aluminium bars, more glass
Before you order: points to check
- Plaster-box depth affects how the lantern looks from below
- Needs a strong, level kerb or upstand
Planning and building rules for Dunoon
Scottish householder permitted development (Class 2B, other external alterations) can cover a rooflight that projects no more than 1 metre from the roof, but the right does not apply in conservation areas. Flats and tenements are outside householder permitted development, so check with the planning authority first.
Scottish energy standards for glazing, including rooflights, use an area-weighted average of 1.4–1.6 W/m²K in extensions, so most modern units comply comfortably. Replacing a rooflight, frame included, does not need a building warrant, but the work must still meet the building standards.
Read the planning permission guide before you commit to a design.

Questions about roof lanterns in Dunoon
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.
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
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.
How do I book a survey in Dunoon?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Dunoon?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
