Sliding rooflights in Dungannon: what is involved?
Thinking about sliding rooflights in Dungannon? 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.
Northern Ireland has a mix of terraces, bungalows and rural farmhouses, and rooflights are a common upgrade when extending. In Dungannon, as anywhere, sliding rooflights are the usual choice for staircases that rise to a roof terrace.
Dungannon is around 36 km from Omagh, and we survey and fit throughout that part of County Tyrone, including the BT70 district.

Consents for sliding rooflights in Dungannon
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. Extensions follow a 25% glazing allowance in Technical Booklet F1.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Is it lockable?
Yes. Units lock from inside and the drive holds the lid closed.
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.
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.
Is the survey in Dungannon free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Dungannon?
