What do roof lanterns in Greenock involve?
Our roof lanterns service in Greenock covers hipped glass lanterns that lift the ceiling of orangeries and extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Tenements and flats are common in Scottish towns and cities, where rooflights over stairwells and top-floor flats need the owners' and factor's agreement. Typical uses for roof lanterns include orangeries, kitchen-diners and single-storey extensions.
We work across Renfrewshire and Inverclyde, including Greenock, and in neighbouring towns such as Gourock and Helensburgh. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Greenock
Planning rules in Scotland differ: rooflights are treated as external alterations under Class 2B, with no permitted development in conservation areas. Listed buildings need listed building consent where the work affects their character.
Under the Scottish building standards, replacement rooflights should average 1.6 W/m²K or better, and no individual unit should exceed 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.

Roof lanterns in Greenock: 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.
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 you work alongside my builder in Greenock?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in Greenock?
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.
