Flat rooflights for St Andrews: the essentials
Flat rooflights in St Andrews means fixed double or triple glazed rooflights for flat roofs and extensions. We cover the KY16 district and the rest of Fife, 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. Flat rooflights suit kitchen extensions, side returns and flat-roofed back rooms.
St Andrews is around 50 km from Dunfermline, and we survey and fit throughout that part of Fife, including the KY16 district.
What you can choose
- Plastered or lined internal reveal
- Integral or fitted blinds
- Solar-control or self-cleaning outer pane
- Frame colours: anthracite, black, white or RAL
- Insulated kerb or timber upstand built to suit
- Inner pane laminated for safety overhead
- Fixed units are simple, quiet and low-maintenance
Things we check at survey
- The roof membrane must be dressed up the upstand before the unit goes on
- New openings in an existing roof need a structural check on joists
Consents for flat rooflights in St Andrews
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. Replacing a rooflight, frame included, does not need a building warrant, but the work must still meet the building standards.
See our building regulations guide for U-values, glazing limits and self-certification.

Flat rooflights in St Andrews: questions
Can a flat rooflight be walked on?
Not unless it is designed as a walk-on unit with structural laminated glass. A standard flat rooflight is for light only — if the roof is used as a terrace, choose a walk-on rooflight instead.
Do flat rooflights leak?
A well-fitted flat rooflight should not leak. Leaks almost always come from the upstand or membrane detailing, not the glass unit, which is why the upstand height and the way the roof covering is dressed up and under the frame matter more than the brand.
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.
Will I need planning permission in St Andrews?
Planning rules in Scotland differ: rooflights are treated as external alterations under Class 2B, with no permitted development in conservation areas.
Do I need to be at home for the survey in St Andrews?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
