Flat rooflights in Lerwick: what is involved?
Flat rooflights in Lerwick: by arrangement. In short, fixed double or triple glazed rooflights for flat roofs and extensions. We confirm travel and timing before any survey is booked, then fix the price in writing.
Stone villas, cottages and conservation areas across Scotland often call for conservation rooflights in slate roofs. Think of flat rooflights for landings, bathrooms and rear extensions with flat roofs.
Lerwick is in a remote or island area, so surveys and fitting here are by arrangement. Send your postcode and we will tell you honestly whether and when we can help.
Specification options
- Insulated kerb or timber upstand built to suit
- Rain sensor if paired with an opening unit
- Frame colours: anthracite, black, white or RAL
- Integral or fitted blinds
- Solar-control or self-cleaning outer pane

Before you order: points to check
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
- The roof membrane must be dressed up the upstand before the unit goes on
Planning, building control and Lerwick
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.
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.

Flat rooflights in Lerwick: questions
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.
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.
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.
