What do flat rooflights in Lockerbie involve?
For Lockerbie 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.
Many Scottish homes have dormers and attic rooms where an extra roof window adds light without a full dormer. Typical uses for flat rooflights include kitchen extensions, side returns and flat-roofed back rooms.
Lockerbie sits about 16 km from Annan and 17 km from Dumfries, and we cover the whole DG11 postcode district and the roads in between.
What you can choose
- Plastered or lined internal reveal
- Rain sensor if paired with an opening unit
- Double or triple glazing
- Solar-control or self-cleaning outer pane
- Integral or fitted blinds
- Fixed units are simple, quiet and low-maintenance
- Double or triple glazed with a warm-edge spacer
What to check first
- New openings in an existing roof need a structural check on joists
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
Consents for flat rooflights in Lockerbie
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. Flats and tenements are outside householder permitted development, so check with the planning authority first.
Scotland's Technical Handbook (section 6) asks for windows, doors and rooflights in an extension to average 1.4–1.6 W/m²K, with no single unit worse than 3.3 W/m²K. Replacing a rooflight, frame included, does not need a building warrant, but the work must still meet the building standards.
Read the planning permission guide before you commit to a design.

Questions about flat rooflights in Lockerbie
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.
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.
Will I need planning permission in Lockerbie?
In Scotland most rooflights on houses fall under Class 2B permitted development; in a conservation area, or on a listed building, consent is needed.
