Sliding rooflights in Tenby: what is involved?
Thinking about sliding rooflights in Tenby? 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.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Sliding rooflights suit walk-out access where a hatch would feel cramped.
Jobs in Tenby 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.
Options we can specify in Tenby
- Electric drive with safety edge
- Box (glazed sides) or flat sliding lid
- Rain sensor
- Anthracite, black or RAL frames
- Integrated balustrade on some ranges
- Glazed box sides keep the headroom open
- Full-width, walk-out access to a roof terrace
Things we check at survey
- The stair opening and headroom must meet Building Regulations
- Weight and point loads need a structural check
Planning, building control and Tenby
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.
Welsh Building Regulations expect new or replacement rooflights to reach 2.2 W/m²K and roof windows 1.4 W/m²K or a Band B rating. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Sliding rooflights in Tenby: questions
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.
Is it lockable?
Yes. Units lock from inside and the drive holds the lid closed.
Will I need planning permission in Tenby?
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed.
Do I need to be at home for the survey in Tenby?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
