Sliding rooflights for Bolton: the essentials
We handle sliding rooflights across Greater Manchester, including Bolton. 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.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. Think of sliding rooflights for staircases that rise to a roof terrace.
We work across Greater Manchester, including Bolton, and in neighbouring towns such as Farnworth and Westhoughton. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Electric drive with safety edge
- Double or triple glazing
- Anthracite, black or RAL frames
- Box (glazed sides) or flat sliding lid
- Integrated balustrade on some ranges
- Daylight down the stair when closed
- 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 Bolton?
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

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.
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 the survey in Bolton free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Bolton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
