Roof lanterns for Alloa: the essentials
Roof lanterns in Alloa means hipped glass lanterns that lift the ceiling of orangeries and extensions. We cover the FK10 district and the rest of the Forth Valley, with a survey before any price is fixed.
Short winter days in Scotland make every square metre of overhead glass count, so rooflight sizing matters. Typical uses for roof lanterns include rooms that need height as well as light.
Alloa sits about 9 km from Stirling and 11 km from Bridge of Allan, and we cover the whole FK10 postcode district and the roads in between.
What you can choose
- LED lighting in the plaster box
- Internal and external colours
- Aluminium or uPVC systems
- Solar-control or self-cleaning glass
- Opening vents with electric control
- Slim aluminium bars, more glass
- Adds visual height to a single-storey room
What to check first
- Some designs project above the roof enough to affect planning on certain houses
- Plaster-box depth affects how the lantern looks from below
Planning, building control and Alloa
Planning rules in Scotland differ: rooflights are treated as external alterations under Class 2B, with no permitted development in conservation areas. Flats and tenements are outside householder permitted development, so check with the planning authority first.
Scotland's Technical Handbook (section 6) asks for windows, doors and rooflights in an extension to average 1.4–1.6 W/m²K, with no single unit worse than 3.3 W/m²K. Forming a new opening normally involves structural work, so check with the local authority verifier whether a building warrant is needed.
Read the planning permission guide before you commit to a design.

Common 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.
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
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.
Can you work alongside my builder in Alloa?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Alloa?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
