What do sliding rooflights in Mitcham involve?
For Mitcham 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.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Typical uses for sliding rooflights include staircases that rise to a roof terrace.
Mitcham sits about 2 km from Morden and 3 km from Wimbledon, and we cover the whole CR4 postcode district and the roads in between.
Specification options
- Double or triple glazing
- Integrated balustrade on some ranges
- Rain sensor
- Electric drive with safety edge
- Anthracite, black or RAL frames
- Electric operation with safety stops
- Replaces a dormer or stair enclosure on some roofs
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
Consents for sliding rooflights in Mitcham
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.
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. 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.

Sliding rooflights in Mitcham: questions
Can children open it?
Controls can be key-switched or placed out of reach. We will set the controls up to suit the household.
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.
What if it is raining?
Fitted with a rain sensor, an electric unit closes automatically. Most also have a manual override for power cuts.
Will I need planning permission in Mitcham?
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.
