Sliding rooflights in Gravesend: what is involved?
Our sliding rooflights service in Gravesend covers box rooflights whose glass lid slides back for walk-out roof access. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Sliding rooflights suit staircases that rise to a roof terrace.
Jobs in Gravesend 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
- Integrated balustrade on some ranges
- Double or triple glazing
- Rain sensor
- Box (glazed sides) or flat sliding lid
- Electric drive with safety edge
- Full-width, walk-out access to a roof terrace
- Lockable from inside
Before you order: points to check
- Needs space on the roof for the lid to slide clear
- Weight and point loads need a structural check
Do you need permission in Gravesend?
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. 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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about sliding rooflights in Gravesend
Is it lockable?
Yes. Units lock from inside and the drive holds the lid closed.
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 children open it?
Controls can be key-switched or placed out of reach. We will set the controls up to suit the household.
Will I need planning permission in Gravesend?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof.
How do I book a survey in Gravesend?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
