How we approach flat rooflights in Lurgan
Thinking about flat rooflights in Lurgan? The short answer: fixed double or triple glazed rooflights for flat roofs and extensions. The longer answer depends on your roof, which is why we survey before we price.
Wind and rain off the Atlantic make upstand and flashing details important on Northern Irish roofs. Typical uses for flat rooflights include landings, bathrooms and rear extensions with flat roofs.
We work across County Armagh, including Lurgan, and in neighbouring towns such as Craigavon and Portadown. Access, parking and how the glass reaches the roof are all checked at the survey.
Choices for your Lurgan project
- Insulated kerb or timber upstand built to suit
- Plastered or lined internal reveal
- Square, rectangular or long-format sizes
- Frame colours: anthracite, black, white or RAL
- Solar-control or self-cleaning outer pane
- Even, top-down daylight across the whole room
- Slim sightlines from inside — mostly glass, little frame
Things we check at survey
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
- The roof membrane must be dressed up the upstand before the unit goes on
Consents for flat rooflights in Lurgan
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. A side-facing window within 15 m of a neighbouring boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Northern Ireland's energy rules assess rooflight U-values in the vertical position — unlike England and Wales — and expect 1.6 W/m²K or Band C for replacements. Extensions follow a 25% glazing allowance in Technical Booklet F1.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about flat rooflights in Lurgan
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.
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.
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.
How do I book a survey in Lurgan?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Lurgan?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
