Sliding rooflights for Guildford: the essentials
Sliding rooflights in Guildford means box rooflights whose glass lid slides back for walk-out roof access. We cover the GU1 district and the rest of Surrey, with a survey before any price is fixed.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. In Guildford, as anywhere, sliding rooflights are the usual choice for staircases that rise to a roof terrace.
Guildford is around 9 km from Woking, and we survey and fit throughout that part of Surrey, including the GU1 district.

Planning and building rules for Guildford
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. 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.

Sliding rooflights in Guildford: 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.
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 Guildford?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Guildford free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
