How we approach sliding rooflights in Whitefield
Thinking about sliding rooflights in Whitefield? 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.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Think of sliding rooflights for staircases that rise to a roof terrace.
Jobs in Whitefield 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
- Electric drive with safety edge
- Anthracite, black or RAL frames
- Box (glazed sides) or flat sliding lid
- Double or triple glazing
- Integrated balustrade on some ranges
- Daylight down the stair when closed
- Electric operation with safety stops
Things we check at survey
- Needs space on the roof for the lid to slide clear
- The stair opening and headroom must meet Building Regulations
Do you need permission in Whitefield?
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. 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
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.
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 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 you work alongside my builder in Whitefield?
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 Whitefield?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
