Flat rooflights in Glasgow: what is involved?
For Glasgow homes and buildings we offer flat rooflights: fixed double or triple glazed rooflights for flat roofs and extensions. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Scottish weather is hard on roofs, so we specify rooflights and roof windows with exposure in mind and fit upstands with generous heights. Flat rooflights suit kitchen extensions, side returns and flat-roofed back rooms.
We cover all of Glasgow and the G1 district, and nearby Rutherglen and Bishopbriggs.
What you can choose
- Square, rectangular or long-format sizes
- Solar-control or self-cleaning outer pane
- Double or triple glazing
- Frame colours: anthracite, black, white or RAL
- Rain sensor if paired with an opening unit
- Inner pane laminated for safety overhead
- Even, top-down daylight across the whole room
Things we check at survey
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
Consents for flat rooflights in Glasgow
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.
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.

Common questions
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 it make the room too hot?
A big unglazed-to-sky area can add solar gain in summer. Solar-control glass, a blind, or pairing a fixed unit with an opening one keeps it comfortable.
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.
How do I book a survey in Glasgow?
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 Glasgow free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
