How we approach flat rooflights in Coalisland
Our flat rooflights service in Coalisland 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.
Many Northern Irish homes have later flat-roofed kitchen extensions where an old dome can be swapped for glass. Think of flat rooflights for kitchen extensions, side returns and flat-roofed back rooms.
Coalisland sits about 6 km from Dungannon and 12 km from Cookstown, and we cover the whole BT71 postcode district and the roads in between.
What you can choose
- Frame colours: anthracite, black, white or RAL
- Rain sensor if paired with an opening unit
- Plastered or lined internal reveal
- Integral or fitted blinds
- Solar-control or self-cleaning outer pane
- Double or triple glazed with a warm-edge spacer
- Inner pane laminated for safety overhead
Before you order: points to check
- 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
Do you need permission in Coalisland?
Most rooflights on houses in Northern Ireland are permitted development under Class B, but not in a conservation area or on a listed building's curtilage. 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. New dwellings must average 1.40 W/m²K across windows, roof windows and rooflights.

Questions about flat rooflights in Coalisland
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.
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.
