How we approach sliding rooflights in Cookstown
Thinking about sliding rooflights in Cookstown? The short answer: box rooflights whose glass lid slides back for walk-out roof access. 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 sliding rooflights include walk-out access where a hatch would feel cramped.
Cookstown sits about 12 km from Coalisland and 15 km from Magherafelt, and we cover the whole BT80 postcode district and the roads in between.

Planning and building rules for Cookstown
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.
For homes in Northern Ireland, Technical Booklet F1 sets 1.6 W/m²K (or WER Band C) for replacement glazing including rooflights. New dwellings must average 1.40 W/m²K across windows, roof windows and rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Does it need planning permission?
A box unit that projects above the roof plane can need planning permission, especially on the front of a house or in a conservation area. We check before you order.
How heavy is it?
Box sliders weigh hundreds of kilograms, so delivery may need a crane or lifting gear, and the structure must be checked.
Can children open it?
Controls can be key-switched or placed out of reach. We will set the controls up to suit the household.
Do you fit sliding rooflights in Cookstown?
Yes. We survey and fit sliding rooflights in Cookstown and across County Tyrone. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Cookstown?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
