Sliding rooflights for Northallerton: the essentials
For Northallerton homes and buildings we offer sliding rooflights: box rooflights whose glass lid slides back for walk-out roof access. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Converted barns and mills in Yorkshire often suit bespoke or ridge rooflights that follow the original structure. Think of sliding rooflights for walk-out access where a hatch would feel cramped.
Northallerton is around 48 km from York, and we survey and fit throughout that part of North Yorkshire, including the DL6 district.

Planning and building rules for Northallerton
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
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.
What if it is raining?
Fitted with a rain sensor, an electric unit closes automatically. Most also have a manual override for power cuts.
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 you work alongside my builder in Northallerton?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
