Sliding rooflights for Staines: the essentials
We handle sliding rooflights across Surrey, including Staines. In short: box rooflights whose glass lid slides back for walk-out roof access. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Typical uses for sliding rooflights include staircases that rise to a roof terrace.
Neighbouring towns include Egham (3 km) and Ashford, Surrey (3 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Staines
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
Is it lockable?
Yes. Units lock from inside and the drive holds the lid closed.
Can you work alongside my builder in Staines?
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 Staines?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
