Flat rooflights in Dudley: what is involved?
Flat rooflights in Dudley means fixed double or triple glazed rooflights for flat roofs and extensions. We cover the DY1 district and the rest of the West Midlands, with a survey before any price is fixed.
Many Midlands semis have had a single-storey rear extension added, and a larger flat rooflight or lantern is often the change that makes it feel finished. Flat rooflights suit kitchen extensions, side returns and flat-roofed back rooms.
We work across the West Midlands, including Dudley, and in neighbouring towns such as Brierley Hill and Tipton. Access, parking and how the glass reaches the roof are all checked at the survey.
Choices for your Dudley project
- Square, rectangular or long-format sizes
- Insulated kerb or timber upstand built to suit
- Plastered or lined internal reveal
- Solar-control or self-cleaning outer pane
- Rain sensor if paired with an opening unit
- Fixed units are simple, quiet and low-maintenance
- Pairs with an opening unit where you also need ventilation
Things we check at survey
- New openings in an existing roof need a structural check on joists
- 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 Dudley?
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Common 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.
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.
Will I need planning permission in Dudley?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line.
Can you work alongside my builder in Dudley?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
