How we approach sliding rooflights in Herne Bay
For Herne Bay 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.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Sliding rooflights suit walk-out access where a hatch would feel cramped.
From Herne Bay to Whitstable, Canterbury and Faversham, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Anthracite, black or RAL frames
- Double or triple glazing
- Integrated balustrade on some ranges
- Electric drive with safety edge
- Box (glazed sides) or flat sliding lid
- Electric operation with safety stops
- Lockable from inside
Before you order: points to check
- Weight and point loads need a structural check
- Needs space on the roof for the lid to slide clear
Do you need permission in Herne Bay?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.

Common questions
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 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.
Can you work alongside my builder in Herne Bay?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Herne Bay?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
