How we approach flat rooflights in Berwick-upon-Tweed
For Berwick-upon-Tweed 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.
Stone villages inland in the North East can have conservation areas where low-profile rooflights are preferred. Typical uses for flat rooflights include kitchen extensions, side returns and flat-roofed back rooms.
Jobs in Berwick-upon-Tweed are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Specification options
- Rain sensor if paired with an opening unit
- Double or triple glazing
- Plastered or lined internal reveal
- Insulated kerb or timber upstand built to suit
- Square, rectangular or long-format sizes
- Inner pane laminated for safety overhead
- Fixed units are simple, quiet and low-maintenance
Things we check at survey
- New openings in an existing roof need a structural check on joists
- The roof membrane must be dressed up the upstand before the unit goes on
Planning, building control and Berwick-upon-Tweed
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.

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.
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.
Can you work alongside my builder in Berwick-upon-Tweed?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Berwick-upon-Tweed free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
