Flat rooflights for Ossett: the essentials
For Ossett 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.
Converted barns and mills in Yorkshire often suit bespoke or ridge rooflights that follow the original structure. Think of flat rooflights for kitchen extensions, side returns and flat-roofed back rooms.
Ossett sits about 3 km from Dewsbury and 4 km from Batley, and we cover the whole WF5 postcode district and the roads in between.
Options we can specify in Ossett
- Rain sensor if paired with an opening unit
- Integral or fitted blinds
- Insulated kerb or timber upstand built to suit
- Frame colours: anthracite, black, white or RAL
- Square, rectangular or long-format sizes
- Fixed units are simple, quiet and low-maintenance
- Pairs with an opening unit where you also need ventilation
What to check first
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
- New openings in an existing roof need a structural check on joists
Planning and building rules for Ossett
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.
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
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.
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 you work alongside my builder in Ossett?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
