How we approach flat rooflights in Portadown
Flat rooflights in Portadown means fixed double or triple glazed rooflights for flat roofs and extensions. We cover the BT62 district and the rest of County Armagh, with a survey before any price is fixed.
Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting. In Portadown, as anywhere, flat rooflights are the usual choice for landings, bathrooms and rear extensions with flat roofs.
Portadown is around 5 km from Craigavon, and we survey and fit throughout that part of County Armagh, including the BT62 district.
What you can choose
- Double or triple glazing
- Plastered or lined internal reveal
- Rain sensor if paired with an opening unit
- Square, rectangular or long-format sizes
- Frame colours: anthracite, black, white or RAL
- Even, top-down daylight across the whole room
- Double or triple glazed with a warm-edge spacer
Before you order: points to check
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
- The roof membrane must be dressed up the upstand before the unit goes on
Planning and building rules for Portadown
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.
For homes in Northern Ireland, Technical Booklet F1 sets 1.6 W/m²K (or WER Band C) for replacement glazing including rooflights. Extensions follow a 25% glazing allowance in Technical Booklet F1.
Read the planning permission guide before you commit to a design.

Questions about flat rooflights in Portadown
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 Portadown?
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.
Do I need to be at home for the survey in Portadown?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
