What do flat rooflights in Perth involve?
We handle flat rooflights across Perth and Kinross, including Perth. In short: fixed double or triple glazed rooflights for flat roofs and extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Short winter days in Scotland make every square metre of overhead glass count, so rooflight sizing matters. In Perth, as anywhere, flat rooflights are the usual choice for kitchen extensions, side returns and flat-roofed back rooms.
We cover all of Perth and the PH1 district, and nearby Auchterarder and Kinross.
Options we can specify in Perth
- Frame colours: anthracite, black, white or RAL
- Insulated kerb or timber upstand built to suit
- Plastered or lined internal reveal
- Integral or fitted blinds
- Square, rectangular or long-format sizes
- Fixed units are simple, quiet and low-maintenance
- Slim sightlines from inside — mostly glass, little frame
Things we check at survey
- The roof membrane must be dressed up the upstand before the unit goes on
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
Do you need permission in Perth?
In Scotland most rooflights on houses fall under Class 2B permitted development; in a conservation area, or on a listed building, consent is needed. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Flat rooflights in Perth: 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 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.
How do I book a survey in Perth?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Is the survey in Perth free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
