How we approach sliding rooflights in Monmouth
For Monmouth 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.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Sliding rooflights suit walk-out access where a hatch would feel cramped.
Jobs in Monmouth are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Box (glazed sides) or flat sliding lid
- Integrated balustrade on some ranges
- Anthracite, black or RAL frames
- Electric drive with safety edge
- Double or triple glazing
- Electric operation with safety stops
- Daylight down the stair when closed
Things we check at survey
- Needs space on the roof for the lid to slide clear
- Electric units need a dedicated supply and commissioning
Consents for sliding rooflights in Monmouth
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Controls can be key-switched or placed out of reach. We will set the controls up to suit the household.
What if it is raining?
Fitted with a rain sensor, an electric unit closes automatically. Most also have a manual override for power cuts.
