Flat rooflights in Greenock: what is involved?
Flat rooflights in Greenock means fixed double or triple glazed rooflights for flat roofs and extensions. We cover the PA16 district and the rest of Renfrewshire and Inverclyde, with a survey before any price is fixed.
Scottish weather is hard on roofs, so we specify rooflights and roof windows with exposure in mind and fit upstands with generous heights. Think of flat rooflights for landings, bathrooms and rear extensions with flat roofs.
Greenock is around 24 km from Paisley, and we survey and fit throughout that part of Renfrewshire and Inverclyde, including the PA16 district.
Options we can specify in Greenock
- Solar-control or self-cleaning outer pane
- Rain sensor if paired with an opening unit
- Frame colours: anthracite, black, white or RAL
- Plastered or lined internal reveal
- Double or triple glazing
- Fixed units are simple, quiet and low-maintenance
- Double or triple glazed with a warm-edge spacer
What to check first
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
- New openings in an existing roof need a structural check on joists
Planning and building rules for Greenock
In Scotland most rooflights on houses fall under Class 2B permitted development; in a conservation area, or on a listed building, consent is needed. Listed buildings need listed building consent where the work affects their character.
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. Forming a new opening normally involves structural work, so check with the local authority verifier whether a building warrant is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
How long does it take?
Fitting into a prepared upstand usually takes a day. Forming a new opening in an existing roof, including making good inside, is often two to three days.
Double or triple glazing?
Double glazing suits most domestic jobs. Triple glazing improves thermal performance and cuts noise from rain, which is worth it over bedrooms or where the energy calculation is tight.
Can you fit into my existing flat roof?
Yes. We form a new opening, trim the joists, build and waterproof an upstand and make good the ceiling. A survey confirms the joist direction and roof build-up first.
Is the survey in Greenock free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Greenock?
Planning rules in Scotland differ: rooflights are treated as external alterations under Class 2B, with no permitted development in conservation areas.
