Sliding rooflights in Magherafelt: what is involved?
Thinking about sliding rooflights in Magherafelt? 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.
Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting. Typical uses for sliding rooflights include staircases that rise to a roof terrace.
Magherafelt sits about 15 km from Cookstown and 24 km from Coalisland, and we cover the whole BT45 postcode district and the roads in between.

Do you need permission in Magherafelt?
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.
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. 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.

Questions about sliding rooflights in Magherafelt
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.
Is a sliding rooflight better than an access hatch?
For daily use, usually yes — you walk out under open sky instead of climbing through a hinged hatch. A hatch costs less and suits occasional access.
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 I need to be at home for the survey in Magherafelt?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Magherafelt?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
