Flat rooflights for Dungannon: the essentials
For Dungannon 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.
Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting. In Dungannon, as anywhere, flat rooflights are the usual choice for kitchen extensions, side returns and flat-roofed back rooms.
We work across County Tyrone, including Dungannon, and in neighbouring towns such as Coalisland and Cookstown. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Dungannon
- Integral or fitted blinds
- Frame colours: anthracite, black, white or RAL
- Solar-control or self-cleaning outer pane
- Square, rectangular or long-format sizes
- Insulated kerb or timber upstand built to suit
- Fixed units are simple, quiet and low-maintenance
- Even, top-down daylight across the whole room
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
Do you need permission in Dungannon?
In Northern Ireland, roof alterations come under Class B of the 2015 order: a rooflight facing a road must not project more than 15 cm and must sit at least 0.5 m from the ridge, eaves, verge and party wall. Listed buildings also need listed building consent from the council.
Technical Booklet F1 (2022) asks for replacement windows and rooflights in existing homes to reach WER Band C or a U-value of 1.6 W/m²K, assessed in the vertical position. Extensions follow a 25% glazing allowance in Technical Booklet F1.

Questions about flat rooflights in Dungannon
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.
How long does it take?
Fitting into a prepared upstand usually takes a day. Forming a new opening in an existing roof, including making good inside, is often two to three days.
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.
Will I need planning permission in Dungannon?
Northern Ireland's householder permitted development allows rooflights within limits — no more than 15 cm projection on road-facing slopes and a 0.5 m margin from ridge, eaves and party walls.
Can you work alongside my builder in Dungannon?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
