Flat rooflights in Telford: what is involved?
For Telford 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.
Industrial and commercial units around Midlands towns often still have their original rooflight sheets, which are due for replacement. Flat rooflights suit landings, bathrooms and rear extensions with flat roofs.
We cover all of Telford and the TF3 district, and nearby Wellington and Bridgnorth.
What you can choose
- Rain sensor if paired with an opening unit
- Solar-control or self-cleaning outer pane
- Square, rectangular or long-format sizes
- Insulated kerb or timber upstand built to suit
- Frame colours: anthracite, black, white or RAL
- Slim sightlines from inside — mostly glass, little frame
- Double or triple glazed with a warm-edge spacer
What to check first
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
- New openings in an existing roof need a structural check on joists
Planning and building rules for Telford
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.

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.
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.
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.
Do I need to be at home for the survey in Telford?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Telford?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
