What do flat rooflights in Omagh involve?
Our flat rooflights service in Omagh covers fixed double or triple glazed rooflights for flat roofs and extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written 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 cover all of Omagh and the BT78 district, and nearby Strabane and Enniskillen.
What you can choose
- Integral or fitted blinds
- Plastered or lined internal reveal
- Frame colours: anthracite, black, white or RAL
- Solar-control or self-cleaning outer pane
- Insulated kerb or timber upstand built to suit
- Even, top-down daylight across the whole room
- Slim sightlines from inside — mostly glass, little frame
What to check first
- New openings in an existing roof need a structural check on joists
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
Planning, building control and Omagh
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. 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.
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 Omagh
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 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.
Will I need planning permission in Omagh?
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.
Is the survey in Omagh free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
